Analysis of a ramp metering application for Mitchell Freeway

Freeways are widely used in major metropolitan cities to respond to the increasing number of vehicle users. Due to such growing demands, it is very important to effectively control and manage freeway traffic. Ramp metering is one of the most common methods used in which the freeway traffic flow is smoothed by means of a traffic signal on a freeway entry ramp. In this study, the effect of ramp metering on traffic of a section of Perth’s Mitchell Freeway was investigated through micro-simulation modelling. A base model was developed and demand estimated – this estimated with the increasing demand of the freeway by scaling the total demand. In the ramp metering installation step, the ALINEA local ramp metering algorithm was used and calibrated to control the flow rates of entry ramps. Finally, the effect of ramp metering on Mitchell Freeway was investigated using different criteria and a discussion was made.
