We propose a new design of a transit system that ensures point-to-point travel using a large number of deployed vehicles such as buses and minivans. The design is based on no more than one transfer during a trip and includes computerized dispatch and routing using probabilistic rules in a real-time management framework. The focus of the presentation is on the routing rules. - WB43.2 Estimation of Freight Origin-Destination Matrices with ITS Data
We will describe a game theoretical formulation that depicts the flow of goods in urban areas as a market in Cournot-Nash equilibrium. The formulation, integrative freight market simulation, decomposes the urban good movement problem in 2 main components: the estimation of the amount of transportation service contributed to the market (in Cournot-Nash equilibrium)... - WB43.3 A Simulation Assignment Model to Evaluate Infrastructure Improvements for Freight Operations in the Chicago Area

We analyze the truck operation in the Chicago area, its effects on both passenger and truck traffic and discuss a means for evaluating potential improvements. Numerous scenarios of infrastructure improvements on the Chicago network are evaluated. A simulation-based traffic model is developed that accounts for the simultaneous routing of passenger and truck traffic in order to develop performance measures... - WB43.4 The Life Expectancy of a Min-Path Tree: A Fast Algorithm for the Dynamic Quickest Path Problem
The algorithm finds a quickest path tree in a network whose arc traversal-times are continuous piecewise linear functions of arrival time. Using a parametric approach, the algorithm transforms a min-path tree for one epoch of departure time into the next earlier epoch at which the tree's topology changes. The local updating technique affects only a small fraction of the tree...
