A centralized traffic controller for intelligent vehicles in a segment of a multilane highway

This paper presents two contributions in the study of Automated Highway System. The first one is a solution to calculate the coordinated movement of intelligent vehicles in a multilane highway for a fixed period of time. An optimization model that considers travel time as criteria and considers topography of the lane, traffic rules and curve of acceleration of each vehicle is presented. The model deals with many traffic situations such as overtaking and reduction in lanes. As the model takes time to run, an algorithm based on traffic simulators is proposed. The other contribution is a solution for the overtaking priority problem and it is based on references provided by the algorithm results. Moreover, new concepts for microscopic traffic assessment are proposed. Simulation tests are presented to evaluate the model and the algorithm.
