Web Application for Transport Infrastructure Simulation

Abstract

The work develops a web application for simulation modeling of road traffic at an intersection in order to optimize traffic flows. Design / Method / Approach. The study uses an engineering and technological approach that involves designing and implementing a web application taking into account the architectural principles inherent in complex object modeling systems. Theoretical implications. The conceptual model allows adapting existing principles of modeling complex systems (in particular, transport networks) to the formats of web-oriented applications. Conclusions. Alternative parameters and sequential algorithms for the functioning of this model have been developed. Detailed flowcharts of each stage have been constructed and the best solution to the problem has been selected. Practical implications. As a result of the implementation of the architecture, a functional prototype has been created that allows modeling traffic in the current time mode. It can be used to analyze the quality of the organization of transport flows, as well as by state institutions, city administrations and project organizations for a visual representation of the transport network or the practical implementation of a functional prototype. Of particular importance is its use in the military sphere as a tool for situational analysis, logistics planning and simulation for making effective decisions in dynamic and dangerous conditions. The value of the study is the basis for the practical application of information technologies in the field of infrastructure planning. The developed model was successfully tested on the example of the multimodal transport system of the city of Dnipro and the organization of road traffic in the city with 5 distributions of transport networks: normal, uniform, decreasing (exponential), increasing, based on real (empirical) data. Research limitations / Further research. The study is limited by the set of input data and the lack of consideration of informal factors that may affect traffic. Further directions of the real-time scenario include: integration with real sources of transport data; implementation of nonlinear, stochastic or neural network approaches; inclusion of modules for assessing network load, CO₂ emissions, impact on the environment and economy of the city. The proposed tool can be used to analyze the efficiency of traffic management, assess the impact of infrastructure changes or test transport policies. Originality/value. The originality of the work lies in the combination of web development and transport modeling approaches in a single architecture focused on interactive simulation of infrastructure objects. Research includes: integration with real sources of transport data; inclusion of modules for assessing network loadin real time.
