| Abstract: | Firstly,the various types of ramp models in the third ring-road of Beijing Expressway were presented based on METANET model.Then,the third ring-road traffic network was established in the Paramics microscopic traffic simulation software.Finally,the optimal control objective was proposed.In the optimization method,the ramp metering time was real-encoded by using the genetic algorithm to optimize the whole control objectives.The result of simulation indicates that the algorithm improves the conditions of the ... |
