The article deals with the priority passage of regulated intersections by public transport using the method of extending the permitting signal. The relevance of the problem under consideration is due to insufficient study of the issue of choosing the optimal control parameters for the method of extending the resolving signal. Using simulation modeling, a study was carried out of the priority passage control process on two- and three-lane road sections. In the course of the experiment, the dependences between the extension time of the allowed signal and the cycle duration were determined at different ratios of the phase coefficients, as well as the optimal distance of the priority activation detectors. The obtained results of the research work can be used in the design of the urban intelligent transport system and when adjusting the control modes in the automated traffic control system of the urban agglomeration.

The largest cities of Russia have problems with the development of rapid transit passenger transport. A good solution to the problem is to replace the tram lines with rapid transit tram lines or light rail (LRT). One of the conditions of a light rail transit is to increase the distance between stopping points. A review of the literature shows that the question of the effect of the distance between stopping points on the tram speed is insufficiently studied. The aim of the study is to determine the relationship between the tram speed and the distance between the stopping points of the light rail system. The research method is simulation at the micro level in Aimsun. The study considered the speed limit, stopping time at stopping points, delays due to signalized intersections. Based on the simulation results, a relationship between the tram speed and the distance between stopping points was determined. The obtained relationship is of practical value and can be used for LRT planning and management in cities.

The article deals with the analysis of intermittent lanes priority based on simulation. The implementation of intermittent lanes priority system is only possible within the framework of urban intelligent transportation system (ITS). In some cases, there are not always enough ITS components for the operation of intermittent lanes priority system. Based on the simulation it is possible to determine the efficiency of the intermittent lanes priority system with the minimum or complete number ITS components. To compare the effectiveness of intermittent lanes priority system the simulation was performed for the four scenarios:
1. Without the use of public transport priority
2. Classically marked priority lane
3. Using the intermittent lanes priority system with a minimum number of ITS components
4. Using the intermittent lanes priority system with the full amount of ITS components
According the results of simulation we concluded that the minimal intermittent lanes priority system is noticeably inferior to a fully functional intermittent lanes priority system on the effectiveness, but such system does not require a high level of development of the urban ITS and can be considered as the first stage of a complete intermittent lanes priority system.
