Abstract

Confined areas present an opportunity for early deployment of autonomous vehicles due to the absence of non-controlled traffic participants. In this disclosure, two approaches for coordination of multiple AVs in confined sites. Each approach computes speed-profiles for the AVs such that collisions are avoided in cross intersections, merge-split zones and narrow road sections. Specifically, this is done by solving an optimal control problem where the motion of all vehicles is optimized jointly. The order in which the vehicles pass the crossings is determined through the solution of a Mixed Integer Quadratic Program. Through simulation results, the capability of the algorithm is demonstrated in terms of performance and observance of collision avoidance constraints.
