Enhancing the Usability of an Intersection Collision Avoidance Simulation Method

The TEXAS Model for Intersection Traffic is a high-quality single-intersection microscopic traffic simulation model developed at The University of Texas at Austin. It analyzes in sub microscopic detail the behavior of driver-vehicle units as they go through an intersection and intermix with other traffic flows. It has detailed intersection geometry, path following, microscopic car following, lane changing, visibility restriction features and surrogate safety measures allowing it to be used for intersection collision analysis. However, its user interface is card-oriented and thus it is extremely difficult to use. Making it easy to use would encourage its use for design of intersections that consider traffic collision and safety potential. Additional changes to the model and new features are needed to enhance usefulness for collision avoidance simulation.
