A SYSTEM OPTIMAL TRAFFIC ASSIGNMENT MODEL WITH DISTRIBUTED PARAMETERS

摘要: In this paper a multidestination system optimal dynamic traffic assignment model with distributed parameters is examined. This can be considered an extension of previous and well known models such as those Merchant Nemhauser (1978) Friesz (1990). Flow dynamics the based on simple continuum for flows composed by several commodities equal propagation characteristics. An important property following that no overtaking occur between different commodities. case flow propagating at constant speed vertical queues end links it possible stable approximation proposed means control problems. For one stable, approximations shown how strengthened Courant-Friedrichs-Levy condition ensures FIFO observance approximating problem. Finally, single destination in network, application extremals calculation method problems developed authors papers also favorable conditions its are discussed.
