Connected and automated vehicles (CAVs) are destined to change how the Texas transportation system operates. TxDOT is responsible for the nation’s most extensive state-level network, and it is essential to explore the potential impacts of CAVs on the design, maintenance, and operation of the transportation system. Research into CAVs’ mobility, environmental, legal, and safety implications for the state of Texas was conducted by UT Austin’s Center for Transportation Research (CTR). This document, Best Practices Guidebook for Preparing Texas for Connected and Automated Vehicles, presents the main points of CTR’s research on CAVs and develops practice recommendations, emphasizing safety, to assist TxDOT in optimally planning for these new technologies using a holistic and qualitative approach.1 Presently, the legal landscape for CAVs is one of much uncertainty and flexibility. Current Texas laws do not directly address such technologies; if this ambiguity remains unaddressed, it could hamper the state’s ability to best prepare for CAV use. The National Highway Traffic Safety Administration (NHTSA) advocates adoption of laws that enable researchers to test CAV technologies while ensuring the safety of test subjects and roadway system users. Most observers, including NHTSA, agree that CAV research still needs development before driverless vehicles are ready for use by the public. In addition to setting the stage for advanced testing, the State must address questions concerning liability in the event of a crash involving CAV technologies like electronic stability control and lane keeping assist. Existing crash responsibility law for conventional vehicles should be updated to reflect the increasing use of automation technologies. A national survey and a Texas survey assessed the current state of public opinion towards existing and forthcoming CAV technologies. The U.S. wide survey’s fleet evolution results indicated that around 98% of the U.S. vehicle fleet is likely to have electronic stability control and connectivity by 2030. Long-term fleet evolution suggests that Level 4 AVs are likely to represent 25% to 87% of the U.S. light-duty vehicle fleet in 2045. Results suggest that 41% of Texans are not ready or willing to use shared autonomous vehicles (SAV) and only 7% hope to rely entirely on an SAV fleet, even at $1 per mile. AVs and SAVs are less likely to affect Texans’ decisions about moving closer to or farther from the city center: about 81% indicated a desire to stay at their current location.
