The article analyzes the experience of using pre-signals to solve the problematic issue of effective traffic management at signalized intersections. Based on the results of the analysis, it has been found that the main directions of using presignals as a means of traffic control on cities highways are the prioritization of public transport on the approach to the intersection and directly at it, as well as the optimization of traffic signal control of local intersections or a group of intersections (coordination). The key criteria for evaluating measures to improve the efficiency of traffic flow management at controlled intersections with the use of pre-signals are traffic delays, time spent by public transport users, the level of service and the queue of vehicles. The main means used to assess the efficiency of traffic signal systems with the use of pre-signals is simulation modeling, for which the most popular software products among industry experts are used - VISSIM, SUMO, AIMSUN. A potential area for further research is the development of principles for selecting and justifying the location of pre-signals on cities highways.Downloads
