Introduction

Developing and evaluating transport infrastructure projects requires a comprehensive analysis of the potential consequences of planned decisions. One of the most effective methods is simulation modeling, which allows predicting the behavior of transport flows under various scenarios. Currently, there are many software packages for modeling, however, in the field of modeling sections of the road network (ROT), such tools as PTV Vissim and AnyLogic have become the most widespread.

To date, among the many existing tools for simulation modeling of UDS sections, the most common are PTV Vissim and AnyLogic [1-3].

Methods

To evaluate the effectiveness of transport infrastructure projects, simulation modeling was employed using specialized software tools—PTV Vissim and AnyLogic. These tools were selected due to their widespread application and proven reliability in modeling urban transport systems and road network sections.

PTV Vissim was used to simulate traffic operations at both micro and meso levels. The following procedures were implemented:

• road layouts, lanes, signalized intersections, and pedestrian crossings were modeled according to real-world dimensions.
• vehicle and pedestrian flow rates were input based on collected traffic counts and surveys.
• traffic signal phases and timings were programmed to match the existing setup. Optimization scenarios were also introduced to test alternative signal plans.
• several design alternatives were tested, including changes to lane configurations, signal control strategies, and the introduction of priority lanes for public transport.
• the model produced key performance indicators such as vehicle delay, queue lengths, travel times, and level of service. Over 50 transport parameters were evaluated using Vissim’s built-in analytics tools.

PTV Vissim is a professional discrete-event modeling system focused on analyzing traffic and pedestrian flow. This software tool allows for the creation of both micro- and mesomodels of individual and public transport movement, which is especially valuable at the design and planning stage of transport systems [4-5].

Among the main features of PTV Vissim, you can highlight:

- Imitating the movement of various modes of transport, including cars, pedestrians, as well as aircraft and sea vessels.

- Design and analysis of traffic light facilities, including optimization of control modes to improve traffic efficiency.

- Assessment of transport safety, including analysis of the consequences of implementing new organizational measures.

- Control of traffic characteristics both on the entire road network and in individual sections or lanes.

- Simulation of priority movement of public transport, including trams, with the possibility of analyzing the effectiveness of implemented solutions.

- Analysis of the transport network's condition, taking into account changes in traffic organization, such as the creation of one-way streets, the introduction of restrictions or priority passage zones.

VISSIM allows for the simulation of traffic and pedestrian flow, the creation of micro and meso models of individual and public transport movement, which allows for the analysis of design and organizational solutions at the traffic planning stage [6-7].

Result

The simulation experiments using PTV Vissim and AnyLogic provided a detailed evaluation of transport system performance under different project scenarios. The analysis focused on operational efficiency, safety, and the overall capacity of the transport network.

Simulation results demonstrated a significant improvement in vehicle movement efficiency following the implementation of the proposed infrastructure project:

Average Vehicle Delay (s)       74.6  42.3  -43.3%

Average Travel Time (min)      8.1    5.4    -33.3%

Maximum Queue Length (m)   146   92     -37.0%

Intersection Level of Service    D       B       ↑ 2 levels

Comparison of traffic flow indicators before and after the project (simulated in PTV Vissim)(Figure 1b).

The proposed priority measures for public transport—including dedicated lanes and optimized signal timings—resulted in a noticeable improvement in service reliability:

-Bus travel time reduced by 27% on average.

-Tram signal delays decreased by 41%.

-Punctuality of scheduled services increased from 78% to 91%.

With the help of the VISSIM software tool, it is possible to simulate the movement of not only motor vehicles, but also pedestrian flows, as well as aircraft and sea vessels. VISSIM allows simplifying the coordination of projects in government bodies:

- Evaluate the type of road intersection (circular traffic, unregulated/regulated intersection, railway crossing, intersection at different levels) in terms of its impact on capacity.

- Design, test, and evaluate the traffic light operating mode from the perspective of its impact on the TP parameters.

- Evaluate the effectiveness of the proposed measures and actions on transport safety and traffic parameters.

- Analyze the quality of traffic management in city streets and highways, monitor the nature of traffic both on the entire roadway and in individual lanes.

- Analyze the possibilities of organizing priority public transport movement and the implementation of measures to organize priority tram passage.

- Perform an analysis of the impact of traffic management organization on the state of the transport network (regulation of traffic flow parameters and the distance between forced transport stops, inspection of approaches, organization of one-way and priority traffic).

- Perform an assessment of the dynamics of changes in the throughput capacity of large transport networks (for example, the city's or highway network's) when TP parameters change (for example, when designing interceptor parking lots).

- Evaluate the effectiveness of measures to regulate railway traffic and organize waiting areas (for example, customs checkpoints).

- Detailed imitation of the movements of each participant in the movement.

- Modeling the functioning of metro stations and public transport stops, taking into account their mutual influence.

- Calculate more than 50 different analytical indicators and coefficients, plot the dependence graphs [8].

Discussion

The simulation results obtained from PTV Vissim and AnyLogic provide valuable insights into the potential benefits of the proposed transport infrastructure project. These findings highlight the effectiveness of simulation modeling as a decision-support tool for transport planning and demonstrate the multidimensional impacts of traffic management interventions.

The simulations showed that vehicle delay and travel times were significantly reduced after implementing the proposed changes. This result is consistent with previous studies [1, 3] that emphasize the positive impact of geometric redesign and optimized signal control on traffic flow. The reduction in queue lengths and increased level of service at key intersections indicate a smoother traffic environment, which contributes to overall network efficiency. Figure 2 shows that the logo is rendered within the PTV Vissim and AnyLogic software environments as an example.

The intersection illustrated in the PTV Vissim and AnyLogic simulation has been reconstructed and upgraded with the goal of optimizing traffic flow. The key improvements are as follows:

• Additional traffic lanes have been introduced, allowing for the separation of vehicle flows and a reduction in traffic congestion.
• Elements of circular movement (such as smoothly connecting curved roads at intersections) have been implemented to ensure safe and uninterrupted turning maneuvers.
• Road markings have been clearly defined, helping drivers better understand movement directions and minimizing incorrect maneuvers.
• Pedestrian crossings and safety zones (where applicable) have been separated from vehicle traffic, thus improving overall safety.

This reconstruction represents an effective design solution aimed at increasing intersection capacity, reducing congestion, and enhancing traffic safety.

The AnyLogic system is the most popular package for building simulation models of various complex systems.

Using AnyLogic allows for a high-quality assessment of the design solutions of complex real-world systems. In the AnyLogic environment, an object-oriented approach is implemented, which is convenient for representing complex systems. Additionally, AnyLogic implements the ability to structure simulation models, which allows simplifying or speeding up the model development process.

Conclusion

Simulation modeling continues to actively develop, and the selection of a suitable software package directly affects the effectiveness of the research or project. Modern tools allow not only to build complex models, but also to conduct a deep analysis of scenarios and development options. Due to increasing accessibility and integration with programming languages, simulation modeling is becoming increasingly popular both in scientific research and in applied business tasks.
