MODELS OF TRAVEL TIME AND RELIABILITY FOR FREIGHT TRANSPORT
This study identifies the causes of delay and unreliability in transport systems and models them in such a way that complete trip time distributions can be obtained. The tradeoff between trip time and rates almost always figures importantly in the choice of mode and shipment size. It is difficult to get good estimate of trip time; multiple observations must be used to get a distribution of travel time which describes not only the average performance of the mode but also its reliability. The attributes of each system are related directly to elements of the mathematical model in order to produce a tool which can easily be used for planning and policy analysis.
