Traffic Organization Issues at Signalized Intersections - Case Study Related to Traffic Distribution Over Lanes

Signalized traffic control may significantly improve traffic safety by eliminating potential collision points within a specified time frame (signalling phase). Traffic organization on multiple-lane inlets requires an appropriate division of traffic over lanes. It is also very important to make it legible and eliminate ambiguity of signals and road signs. The article presents selected aspects of the problem. It discusses real-life examples and simulations aimed at analysing different solutions for multiple lane inlets to signalized intersections. Comparative analysis covers, inter alia, the length of vehicle queues and delays at accesses.
