Variable Speed Limits can affect safety and congestion. To estimate the effects of variable speed limits, the operation value should be calculated with queuing theory. In this model after ts minutes since congestion occurred, the queue length is checked and variable speed limits operation would be started. Under this condition, cars pass the modeling area without congestion within the same travel time with non- controlled condition. The confliction under VSL and that under non-controlled condition were compared using SSAM.
