TRIP TRAVEL TIME RELIABILITY IN DEGRADABLE TRANSPORT NETWORKS
The paper reports on an approach developed to model network performance when its link capabilities are subject to stochastic degradations, as in the form of daily traffic incidents that cause travel time variability. It is assumed that drivers would select routes to lower their travel time variability just as they would to lower their mean travel time. As commuters learn the routes' travel time variability based on past experiences, they factor such variability into their route choice and settle into a long term equilibrium pattern. This route choice behavior is characterized in the face of uncertain travel times with the notion of probabilistic user equilibrium (PUE). A pair of network analysis and design models were developed to consider trip time reliability in a network with stochastic link capabilities. Numerical studies are provided for a 19 link example to show its performance and properties.
