The Transportation Research Board is distributing this circular to make the information contained herein available for use by individual practitioners in state and local transp...
A high capacity communication satellite interconnects scores of ground stations simultaneously. Under the Satellite-Switched/ Time Division Multiple Access (SS/TDMA.) system, each channel of the satellite is allocated to a pair of ground stations for a certain time period, after which the whole set of allocations (called a switch) is changed simultaneously. The problem we address is to minimize...
The Traffic Assignment problem consists in determining the routes used by sets of network users taking into account the link congestions. In deterministic modelling, Wardrop Equilibriums are computed. They can be reduced to huge nonlinear multiflow problems in the simplest cases. In stochastic modelling, Logit Assignments are used. They can be obtained, mainly, by substituting the minplus semir...
This chapter demonstrates an application of agent-based selection dynamics to the traffic assignment problem. We introduce an evolutionary dynamic approach that acquires payoff data from multi-agent reinforcement learning to enable a adaptive optimization of traffic assignment, provided that classical theories of traffic user equilibrium pose the problem as one of global optimization. We then s...
An analytical model is developed to assign regional freight across a multimodal highway and railway network using geographic information systems. As part of the regional planning process, the model is an iterative procedure that assigns multimodal freight traffic to the network to achieve overall network optimum. The procedure integrates optimization programming with traffic assignment, conside...
