COMPARISON OF PERFORMANCE OF TWOPAS AND TRARR MODELS WHEN SIMULATING TRAFFIC ON TWO-LANE HIGHWAYS WITH LOW DESIGN SPEEDS

A comparison of the TWOPAS and TRARR models when used to simulate traffic operation on two-way rural highways with low design speed and two lanes is reported on in this paper. It was found that the TWOPAS and TRARR models are generally comparable in their ability to simulate traffic operations on two-lane, two-way highways. However, the TWOPAS simulation results compared better with field data for roads with an 80-km/hr (50-mph) design speed. This was the case for both a level terrain site and a rolling terrain site. The comparison was made in travel time and percentage time delay. Both models require further work before they can be applied without reservation to the many types of situations that might arise on two-lane roads. It is recommended, however, that TWOPAS be adopted for analysis related to capacity and level of service.
