This paper presents evaluation of a model based Variable Speed Limit (VSL) control algorithm
\nfor maximizing the mobility and safety of traffic network. A Model Predictive Control (MPC)
\napproach is used with traffic prediction and performance evaluation capabilities. Improvement
\nof the network efficiency has been measured in terms of minimizing Total Time Spent (TTS) of
\nall the vehicles in the network. A simulation-based surrogate safety measure Time To Collision
\n(TTC) has been used to capture the probability of collisions between two pair of vehicles. A
\nmulti-criterion objective function has been formulated having Total Time Spent (TTS) as network
\nefficiency measure and Time To Collision (TTC) as the instantaneous safety measure. In order
\nto create an active bottleneck, an artificial collision was created resulting in queue formation
\nupstream of the bottleneck. VSL trigger condition was based on a 'speed drop' algorithm. The
\nperformance of the presented VSL algorithm has been tested using Microsimulation tool
\nVISSIM. Genetic Algorithm is used to calculate the optimized control values by developing a
\nintegrated VISSIM COM-MATLAB interface. The findings from the paper suggest that the
\napplication of VSL can substantially contribute to improved traffic flow and a more
\nhomogeneous traffic situation, which increases safety. The results of the experiments have
\nshown that the proposed approach which is based on driver behaviour can significantly improve
\nnetwork safety condition while still improving travel time of vehicles.<\/p>\n
