Variable Speed Limits (VSL) have great potential for increasing freeway traffic efficiency. This paper presents a multi-segment lane-level VSL system, in which speed limits of each lane can be adjusted respectively. In addition, a simulation-driven method is proposed to test and analyze different VSL strategies with respect of speed, occupancy and travel time. The simulation-driven method is based on the SUMO simulator and traffic control interface. Different commands can be applied to adjust speed limits of edges and lanes. The results show that multi-segment lane-level VSL strategies can significantly improve traffic efficiency. This approach can be applied to a long-distance freeway section with multiple variable message signs.
