Simulating Signal Phase and Timing with an Intersection Collision Avoidance Traffic Model

eTEXAS is an integrated traffic and communications simulator developed in cooperation with the US Department of Transportation (USDOT) to support the development of Connected Vehicle (CV) Apps and to perform research on vehicle and roadside Dedicated Short-Range Communication/Wireless Access in Vehicular Environments (DSRC/WAVE) communications using the Society of Automotive Engineers (SAE) standardized J2735 message set. eTEXAS provides a web based interface including vehicle animations. eTEXAS supports using J2735 messages, and an experimental message set produced by the Federal Highway Administration (FHWA). eTEXAS is a platform to assist organizations developing and validating Apps. eTEXAS integrates a mobility model with a DSRC communications model and simulating the communications of CV Apps deployed on DSRC equipment such as On-Board Units (equipped on vehicles) and Road-Side Equipment (RSE) equipped on infrastructure. The Phase IIB project will prove the Phase II eTEXAS model through field trials, engage stakeholders through training, and enhance eTEXAS with additional features. These features include adding cellular communications as an alternative to DSRC/WAVE, multi-simulator capability to scale via parallel execution of number of communication nodes (in vehicles or road side equipment) and to use eTEXAS as part of a road network simulation with multiple intersections.
