traffic flow

Providing rapid and safe traffic in cities requires the use of a set of planning and organizational measures. While the implementation of architectural-planning measures requires, except for significant investments, a quite long period, organizational measures can lead to a temporary but relatively rapid effect. For this purpose, an analysis of traffic flow metrics on the approaches to the intersection, traffic light cycle, and the traffic phasing is carried out.

The article is devoted to the problem of the impact of street parking on delays and the average speed of traffic flow. The sections with different ways of putting vehicles near the roadway in the central part of Lviv city with the most saturated flow were exposed to scientific scrutiny. For this purpose, the program software PTV Vissim is used. The causes of the impact of street parking on traffic flow speed and roadway capacity are analyzed.

The article is devoted to the methodology and research results of traffic flow parameters on the arterial streets, where different regimes of prioritizing urban public transport operate. The regularities of changes of such parameters make it possible to identify and differentiate the sections of transport network in terms of service efficiency, with the aim to implement various regulatory measures that would help to minimize delays in traffic flow.
