Traditional freeway multi-ramp control methods mostly use coil to collect parameters, which makes the calculation of traffic regulation rate inaccurate and leads to low precision of technical control. To solve this problem, a multi-ramp remote cooperative control technology is proposed. Combining with the cooperative environment of expressway, the paper restricts the main line traffic, calculates the traffic cost of periodic route distance and prediction time after vehicles enter the road network, adjusts the coefficient according to the actual road condition, and when the parameter coefficient is 0, the lowest traffic cost is the optimal planning path, and triggers the route guidance and execution. Taking full account of the ramp total flow constraints, the induction scheme is implemented to obtain the shortest control cycle, and the fuzzy logic algorithm is used to calculate the control rate in the control cycle, so as to achieve the purpose of multi-ramp control. The experimental results show that the control precision of the technology is high, which lays a foundation for the safe operation of expressway.
