“Exploiting Capacity of Managed Lanes in Diverting Traffic around an Incident”

Chou, C. and E. Miller-Hooks (2011)

Pub43This paper studies the potential benefits of traffic diversion in incident management for freeway operations of concurrent flow lane facilities. Techniques that exploit the capabilities of the COM interface of the microscopic simulation tool, VISSIM, were devised for modeling freeway incidents and diversion strategy implementations. The potential for mobility improvement in general purpose lanes as a consequence of diverting traffic around an incident using existing managed lanes and resulting degradation in managed lane performance are considered on a case study. Results from experiments employing the developed simulation tool show that the benefit to general traffic due to implementation of a diversion strategy depends on the relative location of the incident scene to the start point of the diversion opening, total length of access to the managed lane under the diversion strategy, incident duration, and number of lanes blocked (i.e. incident severity). When diversion implementation lags, travel time reductions achieved through diversion are diminished.
