摘要

Automated transit systems are a recent development in transportation technology, intended to serve urban regions and major activity centers such as airports, shopping districts, and universities. The purpose of this work, conducted under the heading of Network and Local Control, was to develop routing and dispatching techniques for vehicles in automated transit systems. In this report, the problem of efficiently routing vehicles from many origins to many destinations in a large automated transportation network is formulated as an optimization problem by using a performance index based on total, time-averaged travel time subject to the dynamic vehicle flow constraints of the network. The flow dynamics are based on a nonlinear model that uses link densities as the state variables. A solution algorithm is designed so that all control computations can be performed in a completely decentralized manner, where information exchange occurs only between physically adjacent wayside control computers. The major result of this work was the development of a routing control algorithm with potential for online application.
