Methodology for Ensuring the Required Level of Traffic Safety at Single-Level Regulated Roads Intersections

摘要

A functional flowchart is presented for the results of the investigations aimed at development of the methodology for automated control systems (ACS) which could evaluate and maintain the required traffic safety (TrS). The flowchart can be used in traffic management schemes (TMS) at regulated (signal-controlled) road intersections (RRI) with various methods of traffic light control in the options with traditional control methods I (phase by phase control) or II (control according to separate directions of traffic) and a new method of combined control of traffic III (various combinations of traditional methods I and II in one cycle of traffic light control). The control methods in ACS at RRI are changed according to the intensity threshold of left-turning and right-turning traffic streams to ensure the traffic safety (TrS) during these maneuvers.
