Uniqueness of User Equilibrium in Transportation Networks with Heterogeneous Commuters
This paper discusses uniqueness of user equilibrium in transportation networks with heterogeneous commuters. Daganzo (1983, Transportation Science) proved the uniqueness of (stochastic) user equilibrium when commuters have heterogeneous tastes over possible paths but identical disutility functions from time costs. We Þrst show, by example, that his result may not apply in general networks if di...
متن کاملModeling User Equilibrium in Microscopic Transportation Simulation
The Transportation Research Forum, founded in 1958, is an independent, nonprofit organization of transportation professionals who conduct, use, and benefit from research. Its purpose is to provide an impartial meeting ground for carriers, shippers, government officials, consultants, university researchers, suppliers, and others seeking exchange of information and ideas related to both passenger...
متن کاملRobust Transportation Network Design Under User Equilibrium
We address the problem of designing a transportation network in the presence of demand uncertainty, multiple origin-destination pairs and a budget constraint for the overall construction cost, under the behavioral assumption that travelers optimize their own travel costs (i.e., the "user-equilibrium" condition). Under deterministic demand, we propose an exact integer optimization approach that ...
متن کاملTopological Conditions for Uniqueness of Equilibrium in Networks
Equilibrium ow in a physical network with a large number of users (e.g., transportation, communication and computer networks) need not be unique if the costs of the network elements are not the same for all users. Such di¤erences among users may arise if they are not equally a¤ected by congestion or have di¤erent intrinsic preferences. Whether or not, for all assignments of strictly increasing...
متن کاملEquilibrium uniqueness with perfect complements
It is sometimes the case that some economic goods are perfect complements to some agents, but not to all agents. As an illustration, consider the following highly stylized story. A regulator faces the problem of pricing the use of a given network, e.g., a highway network. For our purposes, a network is simply a graph, with no loop. Each edge of the graph has a capacity: the maximal amount of tr...
