Potential Impacts of Vehicle Automation on Design, Infrastructure and Investment Decisions - A State DOT Perspective
Connected and autonomous vehicle technologies have the potential to significantly change surface transportation as we know it today. State Departments of Transportation (DOT) need to understand how these new technologies will change their approach to designing, managing and operating existing and planned transportation infrastructure. This paper explores the impacts of connected and autonomous vehicles on design, existing infrastructure and investment decisions, as they relate to State DOTs. The project was commissioned by the Pennsylvania Department of Transportation (PennDOT) with an assumption that all vehicles will be connected and autonomous by the year 2040. Design and investment decisions related to ITS message signs, radio advisories, lane capacity, clear zones, width of lanes and medians, and traffic signals are disaggregated into groups of connected, autonomous and connected automated environments and series of recommendations are provided to PennDOT and State DOTs alike to prepare for and manage the new technologies. Furthermore, a timeline is suggested for the recommended actions to help plan accordingly. The paper discusses a number of key uncertainty factors related to demand requiring state DOTs to make decisions that are robust under a range of conditions. The paper concludes that most decisions impacting State DOTs in the near term will be related to connectivity and vehicle to infrastructure (V2I) technologies such as those related to traffic signals. As technologies progress State DOTs will need to follow the market driven forces while being cautious on new investment decisions that could potentially interfere with V2I deployment and technologies.
