Study on on-ramp control strategy of urban freeway based on fuzzy control

The on-ramp control strategies are classified after expounding mechanism of ramp control strategies of urban freeway. The applicability is summarized respectively based on advantages and disadvantages of each strategy. A new on-ramp control method of urban freeway is proposed by using the fuzzy control algorithm and the support vector machine algorithm, which can satisfy with demands which ramp control strategies should change with real-time changing of traffic condition. At last, some ramp control strategies are given by using control algorithm in this paper, based on the survey data of a main road in Guangdong province. The new control strategies and previous control strategies are applied to ramp control respectively, and new control strategies can satisfy dynamic changes of traffic condition by analyzing survey data, and have a better effect on the on-ramp control than old control strategy.
