Assessment of Rural Road Simulation Modelling Tools

This conference paper, from the 2002 meeting of the Institution of Professional Engineers New Zealand (IPENZ) Transportation Group, presents an assessment of the currently-available rural road simulation modeling tools. The author investigated the merits of these various simulation packages (notably TRARR, TWOPAS, and PARAMICS) for modeling vehicle interactions on rural highways in New Zealand. The study focused on the suitability of these tools for evaluations of crash risk and travel efficiency, particularly prediction of vehicle speeds and bunching in typical highway situations. Traffic on Rural Roads (TRARR) is a micro-simulation model; it models each vehicle individually. Two-Lane Passing (TWOPAS) is a microscopic simulation model of traffic on two-lane rural highways. Parallel MicroSimulation (PARAMICS) simulates the individual components of traffic flow and congestion, and presents its output as a real-time visual display for traffic management and road network design. The author concludes that each of these three packages has some particular strengths over the others. TRARR still has a significant advantage in terms of familiarity to many New Zealand practitioners, and well-established support tools to enhance its ease of use for project evaluation. TWOPAS is similar to TRARR and ongoing development makes it an attractive long-term proposition. PARAMICS can model situations not traditionally provided for by rural simulation models; however, it is more difficult to quickly set up and run and model and obtain the required outputs. Thus, it is important to use different packages on projects, to obtain the most appropriate project evaluation and to develop experience by practitioners.
