In China’s freeways, moving bottlenecks occur frequently, greatly limiting the efficiency of freeway traffic. This paper proposes an on-ramp metering control strategy considering freeway moving bottleneck (ORMCS-FMB) under the intelligent and connection environment, and verifies the effectiveness of this strategy with a micro-simulation software. ORMCS-FMB mainly includes three parts: detecting the moving bottleneck, forming platoons of moving bottleneck, and controlling the ramp metering rate. The proposed strategy first takes the slow car (moving bottleneck) upstream as the head car of the platoon and forms a platoon following the moving bottleneck. This produces a certain gap between the adjacent platoons for the on-ramp merging vehicles. When a platoon arrives within the ramp merging area, the proposed model will calculate the ramp metering rate based on the distance between the lead(last) platoon vehicle and the merging area, and the distance between the adjacent platoons. The simulation experimental results show that ORMCS-FMB can effectively reduce the travel time of the system and improve the traffic capacity within the freeway merging area under a high-flow condition.
