Texas model version 3.0 (diamond interchanges)

The Texas Model for Intersection Traffic has been revised and released as Version 3.0. The new Version 3.0 provides the capability of performing detailed computer simulation of diamond interchanges as well as single intersections. Traffic control choices for actuated diamond interchanges include dual ring controllers operating under "Figure 3, 4, 6, and 7" phase sequence patterns. The basic look and feel of earlier versions of the model have been retained to minimize needs for additional user training. The animated graphics feature has been expanded to include single intersections and diamond interchanges. The progress of each individually-characterized vehicle moving through a simulated intersection or interchange is displayed in real-time or in stop-action on a microcomputer-driven graphics screen. This allows the user to study the overall traffic performance or to examine the behavior of any selected vehicle(s) in great detail. With Version 3.0 of the TEXAS Model that is described in this report, alternative intersection or diamond interchange designs and traffic-control schemes can be evaluated quickly and accurately in a timely and cost-effective manner (A).
