| Abstract: | Based on reasonable hypotheses according to analysis of real road traffic condition,mathematical models for real time control of road traffic signals relating to single-cross-shaped intersection,single-t-shaped intersection,linear regions with three multi-intersections,and net regions with six multi-intersections are built.Utilizing Matlab to generate a real time sequence of vehicle flow which satisfies the Poisson distribution,algorithm are designed and compiled according to optimization objectives.Corresponding numerical sequels are obtained,and the optimized results are discussed. |
| Keywords: | traffic signals real time control optimization algorithm Poisson process |
