In recent years, Variable Speed Limit (VSL) has been emerged as an effective mean of traffic control strategy to improve the mobility and traffic safety. This study analyzed the effects of driver response to VSL on a freeway corridor in the City of Edmonton, Alberta, Canada using VISSIM. A previously developed modified 2nd order METANET model was adopted to implement the VSL control strategy. Various levels of speed compliance were assumed during the simulation. Finally, a simulation case study was analyzed based on the field collected data for driver's response towards posted speed limit. The study findings suggested that even with the lower speed compliance, VSL can still be effective for a traffic stream with lower speed variance. The simulation results also suggested that the adopted VSL control strategy overestimates the VSL effectiveness.
