AbstractWe accelerate the maturity of IntelliDrive applications and unlock the storehouse of modeling detail in TEXAS to organizations building IntelliDrive applications J2735/Dedicated Short Range Communication (DSRC) signal controllers and on-board IntelliDrive systems. We add four SAE J2735 messages: SPAT MapData Basic Safety Messages and Signal Request Message for emergency vehicle preemption. Mappings from TEXAS variables to J2735 message fields are customizable. We add a reverse interface to report vehicle movement to TEXAS users and model seven wireless DSRC channels for vehicle-to-vehicle or vehicle-to-infrastructure communication. eTEXAS interfaces with 3 party physical network models. We catapult TEXAS from its roots as a mainframe batch-oriented simulation that gained a highly usable Java-based graphical user interface into a modern 21st century tool with new animation. We restructure TEXAS as a simulation library component that can be called on to simulate vehicle movement in the next delta of time. We support use of eTEXAS with CORSIM/ corridor simulation; cross-platform execution; execution in a virtual machine; access to eTEXAS as a service for remote cloud or parallel execution; a more realistic model of driver behavior on yellow signals; and interfacing with emulated signal controllers supporting J2735. We enhance our Phase I simulation of Bonneson’s Detection-Control System.
