RELATIONSHIPS BETWEEN TRAFFIC CONGESTION AND SAFETY: A DISCUSSION OF ISSUES AND PAST RESEARCH
This report addresses the following questions as to what might be the expected effect on safety if some of the basic goals of Intelligent Vehicle Highway Systems (IVHS) are met: (1) What would be the safety effect if IVHS increases volume without increasing capacity? (2) What would be the safety effect if IVHS increases volume and capacity? (3) Does congestion, defined here as the ratio of volume to capacity, absolutely have to increase when the V/C ratio approaches 1.0? (4) How is increased traffic movement to be defined?
