Summary

This study addresses the challenges of implementing Intelligent Transport Systems (ITS) in small and medium-sized cities in Russia, where economic constraints often prevent the adoption of advanced traffic management technologies. The research focuses on the main street of Pavlovsk, a city with a population of approximately 25,000, to evaluate the efficiency and economic viability of coordinated traffic control versus full ITS implementation. The primary motivation is to develop alternative, cost-effective methods for managing traffic flow that account for the specific economic realities of smaller urban centers. The methodology involved a comprehensive analysis of a 2-kilometer section of October 40th Street, specifically an 844-meter coordinated segment comprising three intersections. The researchers conducted field studies to determine geometric and traffic characteristics, including traffic intensity, using short-term analysis methods. They performed a 24-hour monitoring of traffic flow to identify periods where coordinated control was ineffective. Additionally, the study utilized AnyLogic simulation software to model traffic delays and calculate the economic impact of different management strategies. The economic assessment included estimating the costs of implementing ITS hardware and software versus using a previously developed algorithm for evaluating coordinated control efficiency. The results indicated that coordinated traffic control is not effective during all hours; specifically, it was deemed inefficient during nighttime and early morning hours when traffic intensity on secondary streets exceeded that of the main street. Simulation data showed that implementing either the evaluation algorithm or full ITS could reduce annual vehicle delays on the main street from 58,238 to 43,966 vehicle-hours, and on secondary sections from 34,847 to 23,674 vehicle-hours. This reduction translates to an annual economic benefit of approximately 11.2 million rubles. However, the cost of full ITS implementation was estimated at 15 million rubles, resulting in a payback period of 1.4 years. In contrast, implementing the alternative algorithm required only 120,000 rubles, yielding a payback period of 0.01 years. The study concludes that while ITS provides operational benefits through constant monitoring, it is economically unjustified for small cities like Pavlovsk due to high implementation costs. Instead, the authors recommend using alternative algorithms to evaluate and optimize coordinated traffic control, which achieves similar reductions in traffic delays (approximately 20%) at a fraction of the cost. This approach offers a sustainable solution for improving traffic management efficiency in low-population urban areas without the financial burden of full-scale ITS infrastructure.
