The invention discloses an SUMO-based highway multi-ramp cooperative sensing and control integrated method. The method comprises the following steps: step 1, constructing a simulation road network; step 2, constructing a required simulation environment; step 3, using the collected traffic flow data as a ramp control basis of the next time period, and performing real-time feedback control in combination with an improved multi-ramp control algorithm Metainea considering the influence of traffic composition so as to realize multi-ramp cooperative sensing and control integration; and step 4, comparing the condition of using the improved Metainea algorithm to perform ramp management and control with the unused basic condition aiming at delay through data generated in the simulation process, and analyzing a result. On the basis of an improved expressway multi-ramp management and control algorithm, a real-time management and control scheme is obtained by inputting required data collected by a detector sensing system, and the traffic flow is controlled at the entrance of an upper ramp so as to improve the travel efficiency of passengers; and multi-ramp cooperative sensing and control integration is realized in the SUMO simulation environment, and the control effect of the improved algorithm is verified.
