The Transport Systems Centre (TSC) is currently conducting a study of Adelaide's Southern Expressway. The Expressway was constructed to complement the transport needs of the population located in the southern areas of metropolitan Adelaide and is unique in that traffic flows in only one direction. The TSC is currently investigating the effects of induced traffic on the network containing the expressway and as part of this research, travel time and fuel consumption data has been collected allowing the direct comparison between using each alternative route. This data has been collected using the TSC's instrumented vehicle which is capable of logging data directly from the engine management system in synchronisation with global positioning system (GPS) receivers. The GPS data provides both spatial and time/distance based data from which various traffic parameters can be derived including travel time, stopped time, travel speeds (instantaneous and average) and various congestion indices. The engine management system module provides data such as time, distance, speed, fuel consumption, RPM, throttle position, engine temperature, engine gear, use of air conditioning and economy/power mode. The data provide the basis for direct comparison of the routes and the formulation of emissions models whereby the net benefit of the new infrastructure can be quantified. In addition to the observational studies, simulation modelling of traffic flows on the Southern Expressway is being undertaken using the Paramics traffic network microsimulation package. Paramics allows the occurrence of traffic incidents and their effects to be studied. (a) For the covering entry of this conference, please see IRRD abstract no. E200397.
