BETTER MANAGEMENT OF TRAFFIC INCIDENTS: SCOPE OF THE PROBLEM

When a major incident causes a bottleneck, significant freeway congestion results even though unused capacity may exist on parallel routes within the freeway corridor. The time an incident occurs and how long it blocks a freeway lane are prime factors that influence the amount of congestion and delay that develops. It is shown that, the more frequently incidents occur, the more frequently congestion will result and that, the longer the duration of the incident is, the more likely severe delay is to occur. Incident detection and types of response systems are discussed in relation to the objectives of the freeway system.
