USER-FRIENDLY TEXAS MODEL - GUIDE TO DATA ENTRY. FINAL REPORT

Two interactive data-entry programs have been incorporated into the TEXAS Model for Intersection Traffic to produce the User-Friendly TEXAS Model. Now, a user, working through an alphanumeric terminal connected in an interactive time-sharing mode to a mainframe computer or through the keyboard of a microcomputer, can enter all the data needed for a simulation run in about 1/10 the time previously required. During simulation, the progress of each individually-characterized vehicle moving through a simulated intersection is recorded and subsequently displayed in real-time or in stop-action on a microcomputer-driven graphics screen. This animated graphics display allows the user to study the overall traffic performance at an intersection or to examine the behavior of any selected vehicle(s) in great detail. Tabular summary statistics are also produced for each simulation run if requested by the user. With the user-friendly version of the TEXAS Model that is described in this guide, alternative intersection designs and traffic-control schemes can be evaluated quickly and accurately in a timely and cost-effective manner.
