“…The modelling of the occurrence of such incidents, and the way in which the effects are propagated through the network is a major task; it is, however, an extremely important area to consider, since the full benefit of a DRG system may only be realised in such situations. We note that incident modelling has already received some attention in the context of route guidance systems (Al-Deek et al, 1989;Bi-eheret et al, 1990;Mauro, 1991).…”

In attempting to simulate the operation of a dynamic route guidance system, the modelling task is concerned both with the operation of the control system and with the implications this has for modelling driver hehaviour (whether or not the driver is receiving information from the controller) and network conditions. The aim of this paper is to provide an overview of the modelling issues which need to be considered when addressing such a problem, and which have been identified by various authors in reports on experimentallsurvey work and in discussion papers.In discussing the great number of challenges to the modelling world which have arisen from the interest in such systems, we seek to stimulate further discussion and to provide a framework within which any route guidance model may be critically evaluated. We consider such a framework to be particularly timely in the light of the wealth of simulation models currently being proposedand widely varying conclusions being drawn -as a result of many major research initiatives currently underway throughout the developed world.It is our belief that the development of a model which adequately represents the performance of a dynamic route guidance system is of the utmost importance to the success of such an approach.It will not only provide a means for evaluating the potential benefits, but should also provide an essential insight into the most appropriate means for its implementation and improve our understanding of transportation networks.

“…Since we have no reliable understanding about how drivers plan on the basis of such information the planning layer reference model is likely to be more complex. It is to be hoped that experiments now underway [17,18,19,20] will improve our understanding.…”

“…For instance, in their Los Angeles study, they found that 93 incidents occurred per one million vehicle miles of travel, though just 6.5% of these incidents were collisions and just 10% of incidents blocked lanes (average duration of 20 minutes). Al-Deek et al (1988 modeled the occurrence of incidents in a highway corridor, and estimated benefits associated with diverting traffic to alternate routes. The dynamics of traffic flows during incidents was also studied by Heydecker (1994) within the context of alternative diversion strategies.…”
