As an efficient traffic control strategy to ameliorate freeway traffic congestion, ramp-metering has been successfully applied in the US. However, the applicability and effectiveness of a ramp-metering strategy are required to be investigated during the pre-implementation phase in order to ensure the success of the implementation. Traffic simulation models can provide a quick and cost-effective way to test and evaluate a ramp-metering algorithm prior to implementation on a freeway network. In this report, one ramp-metering algorithm (Fixed-time ramp metering) has been evaluated over a part of Highway 85 in Waterloo, Ontario. Simulation results show that fixed time algorithm can not improve the condition of Highway 85; in some cases, the algorithm may even delay traffic and increased pollution.
