Results of Research of the Traffic Safety at Signalized Intersection with Countdown Timers

摘要

The article is a continuation of the research work carried out by the authors on determining the impact of the countdown timers on traffic conditions, and--in this case--on traffic safety at the intersections. The paper presents the results of research for assessing the impact of the role of the intersection with the countdown timers in transportation network of the city on the safety of the intersections. Moreover, the article also demonstrates the force of the influence of the countdown timers on the level of traffic safety, depending on the function of the intersection in transportation network. For scientific purposes, the traffic measurements were conducted which have been described in detail in another article [1].
