An Evaluation Of The Joint Operation Of Ramp Metering And Variable Speed Limits Using Corsim

An Evaluation of the Joint Operation of Ramp Metering and Variable Speed Limits Using Corsim

The integrated control scenario is tested against the no control case, the VSL only case and the ramp metering only case. The results (i.e. network wide and link statistics) indicate that the integrated control case outperforms the rest of the traffic management scenarios.

Evaluating Ramp Metering and Variable Speed Limits to Reduce Crash Potential on Congested Freeways Using Micro-simulation

Recent research at UCF into defining surrogate measures for identifying crash prone conditions on freeways has led to the introduction of several statistical models which can flag such conditions with a good degree of accuracy. Outputs from these models have the potential to be used as real-time safety measures on freeways. They may also act as the basis for the evaluation of several intervention strategies that might help in the mitigation of risk of crashes.
