User-Friendly Interface for Rural Highway Computer Simulation Models withEmphasis on the Incorporation of the TWOPAS Model

摘要

Rural highways account for the majority of the highway mileage present in theUnited States and many other countries. As such an important element of the transportation infrastructure, there is an ongoing demand for tools with which to assess their operating and safety characteristics, improvement possibilities, and general effectiveness. Computerized simulation models developed specifically for two-lane two-way rural highways have been used as powerful tools in making such assessments. Two such models are TRARR, developed by the Australian Road Research Board, and TWOPAS, developed by the FHWA. UCB developed a user-friendly interface for the TRARR model under previous projects, This report documents the incorporation of TWOPAS model into the same interface which is called UCBRURAL. This report also contains a detailed description of how to use the UCBURAL interface to make either a TRARR or a TWOPAS run.
