      <title>1. Introduction</title>
      <p>Road transport is the main element of domestic transportation for most countries, acting as a
key component of the transportation system and playing a significant role in ensuring
economic growth and social development. The growth of the car fleet is accompanied by
negative consequences in the field of road safety, ecology and the use of natural resources [1].
Continuing to study the issues of road transport, it should be noted that the presence of cars
on the roads is accompanied by other negative consequences. Among them are traffic jams
that occur in large cities and on cross-country routes, which lead to increased fuel
consumption and time for road users [2].</p>
      <p>Despite its obvious advantages in terms of mobility and economic development, road
transport also creates a set of problems related to road safety, environmental pollution, and
infrastructure costs that require attention and systematic work to address.</p>
      <p>In most megacities, automobile exhaust emissions account for a significant share of total
atmospheric emissions. This factor seems to be particularly critical in the context of air
pollution, which leads to serious consequences for human health and the ecological balance.
The negative impact on the atmosphere caused by road transport requires immediate
measures to reduce toxic emissions and ensure sustainable use of natural resources.</p>
      <p>This situation indicates the need for active reorganization and improvement of the transport
system, given the high level of impact of road transport on the social, economic and
environmental aspects of modern society. It should be noted that managing the formation of
toxic substances in exhaust gases requires a systematic approach and the implementation of
evidence-based strategies. The key contribution to total emissions is made by chemical
processes in the engine combustion chamber. Taking into account the impact of driving mode
on emissions emphasizes the need to regulate these processes depending on the operating
conditions of the vehicle.</p>
      <p>The main contributions of this study are:
• A modeling environment has been developed that allows creating realistic models and
experimenting with various parameters to optimize traffic in an urban environment.
• The concept of separation of the modeling environment and the software base was
introduced to ensure flexibility and adaptability. This allows the use of different
technologies to optimize different aspects of urban mobility.
• Active agents have been researched and implemented to optimize traffic flow
management. Agents provide autonomy, adaptability, and distributed
decisionmaking, which increases the efficiency of traffic management.
• Experimental studies of the application of the model environment on the example of
the city of Khmelnytskyi aimed at optimizing the duration of green light at traffic
lights in order to reduce CO2 emissions have been carried out. The results obtained
indicate significant improvements in environmental performance.
• The importance of improving the parameters of the transport infrastructure to achieve
a more sustainable and environmentally friendly urban transport system has been
revealed.</p>
      <p>The structure of the paper is as follows. Section 2 analyzes previous research related to
intelligent transportation systems and urban mobility management. Section 2 provides a
detailed description of the method used in the research aimed at optimizing traffic flows and
urban mobility systems. The presentation of the model in the modeling environment is
investigated, including a description of the model display in a specialized modeling
environment for experiments and optimization. Section 4 presents an experiment to evaluate
the effectiveness of the proposed approaches in real-world conditions. The Discussion section
includes an analysis of the experimental results and their further discussion with regard to
possible applications. The Conclusions section summarizes the research and identifies the
main conclusions arising from the results of the work.</p>

      <title>2. Related Works</title>
      <p>Traffic's environmental impact includes emissions of harmful substances, air and water
pollution, acoustic pollution, loss of natural habitats, resource consumption, energy
consumption, and climate change. The solution to these problems includes the development of
efficient transportation systems and the use of more environmentally friendly technologies. A
number of scientific studies have been devoted to solving problems from a range of complex
solutions as intelligent transportation system [3-5]. The scientific community pays
considerable attention to the problems of reducing the impact of transport on the
environment in order to reduce environmental impact. Thus, research is being conducted in
terms of optimizing traffic flows using modern capabilities with indirect measurements of
traffic density. Although intelligent transportation systems have a wide range of challenges
[6, 7], the development of individual components is yielding positive results. The analysis is
extended to geographic areas, including intersections and road infrastructure, to provide
adequate solutions for traffic optimization, especially at intersections [8, 9]. Methods of
improving neural networks are actively developing and achieving good results, at the same
time, practical application is of great importance [10-12]. Various graph neural networks, such
as convolutional graphs and attention graphs, are used to solve traffic forecasting problems in
the context of traffic. These methods are used in various forecasting tasks, including traffic
forecasting, speed forecasting, and passenger flow forecasting in urban transportation systems
[13].</p>
      <p>The main aspect of such research is the data-driven approach, which involves the use of
historical data for forecasting. The problem of traffic forecasting turns out to be extremely
complex, as it involves large amounts of data with high dimensionality and multiple
dynamics. This is compounded by the consideration of emergencies, such as road accidents,
repair work, periodic traffic jams, etc. Spatial and temporal dependence is recognized as an
essential feature of traffic conditions. It takes into account the influence of not only
neighboring areas, but also temporal fluctuations, including seasonal variations. Traditional
linear time series models, such as regression models, are ineffective in addressing such spatial
and temporal forecasting challenges. Machine learning and deep learning techniques are
widely used in the traffic management industry to improve forecasting accuracy. For example,
convolutional neural networks are successfully used to model the entire city in the form of a
grid. For tasks where traffic is represented in the form of a graph, such as in road networks,
graph neural networks are widely used [14].</p>
      <p>In many cases, existing methods of spatio-temporal modeling do not provide sufficient
attention to the dynamic characteristics of the relationships between points in the road
network. In particular, most works based on recurrent neural networks have limited efficiency
due to the repetitive nature of their structures. In addition, the lack of proper comparison of
different methods on the same data sets remains a problem [15-16]. Modern traffic forecasting
experts mainly use heuristically constructed static traffic graphs, which may not accurately
reflect traffic dynamics. Previous attempts to use dynamically generated traffic graphs also
face problems such as long model training time and a decrease in model quality in terms of a
number of characteristics [14, 17].</p>
      <p>In order to fully automate the network, which can be a likely tool in solving current
challenges related to traffic forecasting in urban environments, detailed data analysis is
required [18]. The use of machine learning models based on historical data is a common
practice for traffic forecasting. This helps to develop solutions for optimizing traffic flows and
facilitates the forecasting of passenger traffic. Research on real-time data, despite the
randomness of traffic flow trajectories, demonstrates the possibility of predicting user
movement [19, 20]. Among these methods, the use of Markov chain-based methods along
with graph neural networks stands out, as it is characterized by its lower complexity [21, 22].
A special place is occupied by papers that determine the trustworthiness of decisions made by
AI [23-25], since vehicles are means of increased danger.</p>
      <p>It is important to note that in order to achieve full network automation and address the
current challenges of traffic flow forecasting, it is necessary not only to take into account
historical data but also to focus on the dynamics of traffic. Some studies, based on real-time
data, try to predict user movements while taking into account a high degree of uncertainty in
traffic flow trajectories.</p>
      <p>In particular, when studying movements that determine the trajectories of users from
source to destination at different intervals, it is important to use comprehensive mobility
forecasting studies. Experts also study various methods for predicting user mobility patterns
[26]. A set of studies in the field of traffic flow and passenger movement forecasting using
machine learning and deep learning methods is a relevant and important area of development
for further optimization and automation of transport systems in urban environments.
However, an environment for adaptive traffic management and meeting objective functions is
important for simulation modeling of urban mobility systems and optimization of
environmental impact on the environment. The simulation environment should correspond to
the urban implementation environment for specific operating conditions and be able to
reproduce the scenarios of the adaptive control system and the likely traffic context.</p>
      <p>It is important to note that successful modeling of the urban mobility system and
optimization of the environmental impact on the environment largely depends on the quality
of the simulation environment. This environment must be specifically adapted for effective
traffic management and meet the target functions of the system. It is also important to ensure
that the simulation environment is adaptable so that it can effectively respond to changes in
traffic conditions and urban dynamics. This includes the ability to take into account various
traffic management strategies, accident prevention, traffic signal optimization, and other
aspects that affect the efficiency of the urban mobility system and environmental
sustainability. Simulation modeling and adaptive traffic management are key to such tasks.
Successful implementation of algorithmic solutions in a real-world environment requires
experimental testing of the relevant models.</p>
      <p>This study focuses on creating an analytical environment for effective simulation
modeling. The main goal is to thoroughly analyze the impact of various traffic signal control
methods on exhaust gas emissions and noise generation during road traffic. The study is
based on specific practical observations and the use of a simulation model that reflects
realistic traffic conditions.</p>

      <title>3. Research method</title>
      <p>Building a modeling environment for urban mobility systems and traffic flow services has an
important scientific and practical justification. Research in this area is aimed at developing
and improving algorithms, methods, and models that will optimize traffic flow, reduce
congestion, and maximize the efficiency of urban mobility systems.</p>
      <p>However, in addition to the scientific aspect, building such an environment also solves
specific problems for the practical implementation and support of real traffic flow systems.
The modeling environment should be able to optimize traffic. The development and
implementation of traffic signal control algorithms, public transportation routes, and
coordination systems help to effectively regulate traffic, reducing travel time and congestion.
Be able to use predictive models to anticipate and adapt to changes in traffic flows, events, or
emergencies. Efficient use of resources, which means that vehicle distribution models are
developed and public transport operations are optimized to use resources efficiently and
reduce emissions. Be able to interact with the real world. Apply realistic modeling of
interaction with existing infrastructures, including roads, traffic lights, parking lots, and other
elements that affect traffic flow. Support real-time decisions. Develop systems that can
provide recommendations and make decisions in real time to effectively manage traffic flows.</p>
      <p>Thus, building an environment for traffic flows should not only improve scientific
research, but also create a basis for the practical implementation and optimization of real
systems in the field of urban mobility.</p>
      <p>The functionality of the modeling environment and the program basis in the context of
scientific research and practical application must interact harmoniously for effective modeling
and optimization of urban mobility systems. This means that the modeling environment
should provide the ability to create realistic models and flexible parameter configuration for
conducting various experiments. The main aspects of the interaction between the
functionality of the modeling environment and the program basis are presented in the Table 1.</p>

        <p>The program basis, in turn, should be developed taking into account the needs of the
modeling environment, ensuring efficiency and flexibility of interaction with agents and
systems. This includes creating user-friendly interfaces for agent configuration, developing
algorithms for modeling their behavior and interaction. It is also important to ensure the
ability to collect, process, and analyze data, as well as integrate with real-world data collection
technologies. The program basis should support experiments, analysis of results, and
optimization tests.</p>
        <p>The main goal is to create such a relationship between the modeling environment and the
program basis that would ensure effective modeling, analysis, and improvement of urban
mobility systems in a real urban environment.</p>
        <p>The separation of the modeling environment and the software base in traffic flow
modeling systems is due to several important aspects. First, it provides flexibility and
adaptability in research, allowing the use of different software solutions for different aspects
of research. This approach allows choosing the best technologies and integrates different tools
to maximize the efficiency and accuracy of the results.</p>
        <p>The second aspect is scalability. Large and complex studies may require the use of different
tools, and the modeling environment can serve as a platform for efficiently managing the
interaction of different software bases. This approach helps to optimize the use of resources
and ensures scalability of research.</p>
        <p>The third aspect is data integration. The modeling environment can serve as a platform for
data integration and processing, and the program basis can be used to analyze and display
results. This helps to optimize information processing and facilitates the collaboration of
different tools. In general, the separation of the modeling environment and the program basis
is a key strategic approach aimed at ensuring flexibility, efficiency, and adaptability in traffic
modeling. The functionality of the modeling environment in the context of scientific research
and practical application should closely interact with the functionality of the software base for
effective modeling and optimization of urban mobility systems.</p>
        <p>The functionality of the modeling environment in scientific research and practical
application should be based on the functionality of the program basis. Accordingly, this can be
represented as follows. Let M be a modeling environment and P be a program basis. The
functionality of M is based on the functionality of P from the main categories given in the
Table 1.</p>
        <p>
          M = f (P),
(
          <xref ref-type="bibr" rid="ref1 ref12 ref23">1</xref>
          )
where f is a function that defines the relationship between the modeling environment and
the program basis.
        </p>
        <p>This function may include such aspects as:
– modeling of conditions
– effective agent modeling
– flexibility and adaptability</p>

        <p>It can be noted that the set of functions of the modeling environment M is absorbed by the
set of functions of the program basis P:</p>
        <p>M ⊆ P.</p>
        <p>The program basis should provide the ability to implement all the necessary functionality
of the modeling environment and not limit research and practical use. At the same time, the
program basis should be beta extensible and have sufficient flexibility to be extended to meet
the needs of scientific research and development. Such an approach reflects the complex
interaction between the functionality of the modeling environment and the program basis,
which allows to effectively solve the problems of scientific research and practical use in the
field of urban mobility systems.</p>
        <sec id="sec-3-1-1">
          <title>3.1. Application of active agents in the intelligent transportation system</title>
          <p>The use of active agents in modern systems and technologies has sound reasons and
important advantages. The use of active agents has a set of advantages, especially when they
are used in systems to optimize their performance according to quality criteria.</p>
          <p>Active agents can act autonomously and independently, making decisions without
constant intervention from centralized management. This ensures more efficient and flexible
management in different scenarios. Agents can adapt to changes in the environment and
operating conditions. Their adaptive capabilities allow for more flexible and effective
solutions in variable environments. Active agents are based on a distributed architecture
where different agents can work in parallel and independently. This makes the system less
vulnerable to failures and allows expanding functionality by adding new agents. Agents have
the ability to work based on local knowledge, which allows them to make decisions based on
limited information. This is especially useful in distributed and dynamic systems. Active
agents can use machine learning techniques to improve their performance on their own and
make optimal decisions based on experience. The distributed nature of active agents
contributes to the efficient use of resources, as they can work in parallel and dynamically
respond to current conditions.</p>
          <p>Combining these advantages, active agents are an effective tool in the development of
systems and technologies where flexibility, efficiency, and adaptability are important. Let us
consider the model of the active influence system from the point of view of an active agent in
the context of optimizing the model parameters in the model environment built into the
program basis (Fig. 2). In this case, the active agent can perform a number of functions and
interact with elements of the modeling environment and the program basis.</p>
          <p>In the process of the modeling environment, the active agent can contribute to the
optimization of model parameters by interacting with various elements of the environment.
This may include changing parameters by agents to influence modeling conditions and
algorithm performance. The agent may also interact with algorithms to facilitate the
implementation and optimization of algorithms in the simulation environment. This may
include selecting and adapting algorithms depending on the needs of the model.</p>
          <p>The active agent can detect dynamic changes in model parameters and independently
adapt them in real time to optimize model performance in changing conditions. Interaction
with the configuration of the program basis is also important, and the agent can adjust the
parameters of the program basis to achieve optimal interaction with the modeling
environment. The agent can also participate in data collection and analysis, determining
which model parameters or properties should be measured and analyzed to achieve better
performance.</p>
          <p>The agent also has the ability to select impact scenarios. This feature allows the active
agent to define specific situations or conditions to which it should direct its influence as part
of the model parameter optimization. The agent can analyze the current state of the model
environment and identify potential influence scenarios that can improve or optimize the
model performance. The choice of a particular scenario may depend on various factors, such
as changes in traffic conditions, weather conditions, or specific user requirements.</p>
          <p>This feature allows the agent to be flexible and adaptive to various situations that arise
during the modeling process. Choosing the optimal impact scenario can significantly improve
the efficiency of parameter optimization and the model's performance in general. In addition,
the active agent constantly adapts to new conditions and requirements of the modeling
environment to ensure the effectiveness of parameter optimization. This approach allows the
modeling environment and the program basis to interact and optimize in real time,
responding to changes in the input data, modeling conditions, and user requirements.</p>
          <p>This approach provides interaction between the modeling environment and the program
basis for the effective use of the agent-based approach in research and practical applications
of urban mobility systems.</p>

          <title>3.2. Model representation in the modeling environment</title>
          <p>Let's consider the formal representation of the model that will be used in the modeling
environment in order to achieve the effectiveness of the objective function. Let's define the
objective function in terms of reducing environmental impact within urban mobility by
optimizing traffic flow regulation.</p>
          <p>The objective function for optimizing traffic flow management within urban mobility with
a focus on reducing environmental impact can be formulated with the identification of factors
that take into account various aspects of sustainability, comfort, and environmental
performance. The general objective function is presented in the form:</p>
          <p>φopt =Eco,Comf , Sust ,
where φopt – the target optimization function;</p>
          <p>Eco – environmental indicator (CO2 emissions or other pollutants);
Comf – comfort (average speed, waiting time, etc.);</p>
          <p>Sust – sustainability of traffic flows.</p>
          <p>The challenge is to find the optimal traffic management that maximizes comfort and
sustainability while minimizing environmental impact. This is a simple example, and there
may be more parameters and constraints in real-world conditions. Optimizing the objective
function may involve the use of mathematical optimization methods.</p>
          <p>The model for the environmental impacts of traffic flows in urban mobility is defined as
follows:</p>
          <p>Eco = Trf , Emis,VihT , EmisSt,TtfPat, RdTopl,CondAtm ,
where Trf – traffic or traffic volume;</p>
          <p>Emis – emissions per unit of traffic;
VihT – types of vehicles by fuel consumption;
EmisSt – emission standards and approaches for determining transport emissions;
TtfPat – parameters of transport movement, such as speed and other factors;
RdTopl – road topology;</p>
          <p>CondAtm – atmospheric conditions.</p>
          <p>
            Each of these factors represents an additional level of detail to account for different aspects
that affect vehicle emissions. More complex dependencies with additional factors may be used
in the specification of studies and models, depending on the specific data and research
objectives. On the basis of the presented models, we will conduct experimental studies of the

      <p>Let's define the real-world environment for modeling the traffic control system. The
realworld environment for modeling of the traffic control system in the city of Khmelnytskyi
includes various infrastructure and organization aspects of the transportation system. The city
has different road types, such as main, arterial, and local roads, which connect different parts
of the city. Intersections and interchanges regulate traffic using traffic lights and roundabouts.</p>
      <p>The city is also served by public transportation, such as buses and trolleybuses, which
provide transportation to the different parts of the city. Pedestrian zones, central squares, and
bicycle lanes contribute to pedestrians and cyclists’ safety.</p>
      <p>The infrastructure also includes parking lots and parking garages, while electronic traffic
control and monitoring and management systems help to optimize traffic. Environmental
aspects are taken into account through green areas and alleys aimed at reducing emissions
and improving air quality.</p>
      <p>For this purpose, let's use the urban road system of Khmelnytskyi, which is shown in
Fig. 3.</p>
      <p>When analyzing the traffic flows of districts in the city of Khmelnytskyi, traffic lights are
identified as key points of intervention in urban mobility, which have a decisive impact on the
efficiency of the transport system. The a priori analysis identified the following critical points.</p>
      <p>Traffic lights are located in the central areas where main and arterial roads are intersected.
Traffic lights are also important at the entrances to the city from highways and main
thoroughfares. A separate category is the traffic lights at the intersections of bus and
trolleybus routes.</p>
      <p>Traffic lights are also identified in areas with heavy pedestrian traffic, such as around
shopping centers or educational institutions. Particular attention is paid to the traffic lights in
areas where traffic congestions often occur, as well as at bottlenecks and overpasses. In
addition, traffic lights in the areas of transfer to different types of transport are considered, as
these are key nodes of citizens’ mobility and movement between different vehicles.</p>
      <p>Identification of these critical points of traffic signal control allows us to set up an optimal
traffic management regime, direct efforts to improve urban mobility and reduce traffic
congestion. After analyzing the traffic flows of the districts in terms of urban mobility, we will
determined the set of traffic lights, which, according to the a priori analysis, have the most
significant impact on the functioning of the transport system Fig. 4.</p>
      <p>The city of Khmelnytskyi is divided into different districts with defined vehicle routes. In
the central business district, which covers the city centre, there are main and arterial routes
with marked traffic lights at intersections. Residential areas have their own road routes, with
traffic lights at main streets and at the entrances to residential areas. Industrial zones also
include designated routes with their own traffic signal control points for traffic efficiency.</p>
      <p>The city of Khmelnytskyi has a set of notable traffic zones, each with its own
characteristics and dynamics. Green zones are the starting points of traffic, defined as places
where vehicle depart. This scenario describes the typical traffic in the morning. The vehicles
in these zones go to their destinations, represented by the purple zones Fig. 5.</p>
      <p>The purple zones are the final destinations where the vehicles are headed to. Each of these
zones represents a separate direction or area of the city. Thus, vehicle from the green zones
are directed to purple zones, making trips from one end of the city to the other. In addition to
the planned traffic, 30% of random traffic was included in the emulation. This random traffic
has no specific directions, and is "fixed" – it moves randomly on each run of the emulation,
but with a fixed direction on each run.</p>
      <p>This approach allows simulating the vehicle movement in the city, with taking into
account the main directions of departure and arrival, as well as additional elements of
unpredictability characterized by the random traffic. We initialized the sets of green light
durations for traffic signals and conducted experimental studies to determine whether it is
possible to optimize the objective function, which we defined as CO2 emissions, according to
this criterion. We set up the parameters of green light duration for the traffic lights and
conducted experimental studies to determine the possibility of optimizing these parameters
with respect to the CO2 emissions criterion. This criterion will act as an objective function in
the optimization process.</p>
      <p>By varying the duration of the green light at traffic lights, we determined the impact of
this parameter on CO2 emissions. This allowed us to find the optimal mode of traffic lights
operation that reduces CO2 emissions while ensuring efficient traffic flow.</p>
      <p>Experimental studies will help to determine the optimal values of green light duration for
each traffic light, taking into account the traffic intensity in specific areas of the city and the
impact on CO2 emissions (Table 2).</p>
      <p>The results of the experimental studies indicated that significant improvements in CO2
emissions can be achieved by optimizing the duration of the green light at traffic signals.
These results indicated that the introduction of optimal parameters for the duration of the
green light leads to a systematic reduction in CO2 emissions at city intersections (Table 3, 4).
Negative values indicate a positive impact of optimization on environmental indicators.

      <p>The results of the experimental studies conducted indicate a great potential for optimizing
traffic in terms of environmental impact. This indicates the possibility of improving the traffic
control system to reduce emissions and improve the environment of urban space. The
proposed system of modeling environment and program basis on the example of application
indicates the presence of the necessary flexibility and adaptability to the needs of
experimental research.</p>
      <p>The results obtained indicate the importance of improving the parameters of traffic lights
and other elements of transport infrastructure to achieve more sustainable and
environmentally friendly urban transportation systems. The enormous potential in this area
points to the need for further research and implementation of optimized traffic strategies to
ensure more efficient environmental friendliness of urban transport. Thus, in comparison
with the most undesirable set of green traffic lights, the integrated indicator of improving the
time of transport movement is respectively Set2 - 2.6%, Set3 - 3.6%, Set4 - 8.2%. If we choose
the volume of CO2 emissions as the optimization criterion for the same data sets, we get the
following results: Set2 - 2.5%, Set3 - 3.1%, Set4 - 7.4%. The conducted studies indicate that the
proposed approach to the formation of the model environment and program basis has
significant potential, especially in terms of using an active agent to adapt the conditions of
traffic management in urban areas. The goal of the research was achieved and the results
showed that the program basis should have sufficient flexibility in relation to the research
tasks and be able to properly meet the research objectives in the process of active scientific
research. The proposed approach to the delineation of environments from the standpoint of
design solutions indicates good prospects for further research on the development of a system
of active and adaptive influence on traffic flows. Accordingly, the proposed system of research
environment structure structures the research environment and does not limit the possibilities
of scientific research, but rather stimulates its flexibility and adaptability, allowing to focus on
the process of scientific research.</p>
      <p>The study was limited to optimizing traffic light duration and measuring the impact on
CO2 emissions. Also, the study concerned only the city of Khmelnytskyi. This limitation is
justified by the fact that the application problem is considered, since general methods under
specific application conditions leave many aspects out of consideration. And these aspects can
have a decisive influence on the final result</p>

      <title>6. Conclusions</title>
      <p>The conclusions of the experimental studies on optimizing the duration of green light at
traffic lights in Khmelnytskyi confirm the significant potential for reducing CO2 emissions
and improving environmental performance in urban transport.</p>
      <p>The experiment showed that the introduction of optimal parameters for the duration of
traffic lights led to a significant reduction in CO2 emissions at various intersections in the city.
The proposed system of modeling environment and program basis, based on the example of
application, demonstrates the necessary flexibility and adaptability to the requirements of
experimental research. The flexibility of the system lies in the ability to adapt the parameters
of traffic lights and other elements of urban infrastructure to identify optimal decision to
reduce CO2 emissions. Optimizing traffic lights reduced CO2 emissions by 2.5-7.4% compared
to non-optimized light durations, showing potential to improve air quality.</p>
      <p>The study was conducted with the limitation that the objective function was CO2
emissions as an environmental impact. This limitation is due to the fact that the effectiveness
of the proposed method was determined within the scope of this study, with the aim of
obtaining a positive result. Therefore, including more parameters in the model, such as speed
limits, lane configuration, public transport routes, etc., will bring the model closer to real
conditions. Also, measuring other pollutants besides CO2, such as NO, solid particles, VOCs
will allow a more objective look at the study results.</p>
      <p>To summarize, optimization of urban traffic lights is a promising area for improving
environmental performance and creating more sustainable transportation systems, and the
use of a modeling environment approach and program basis are effective tools for applying
active agents to influence the modeling environment.</p>
