Impacts of Connected Vehicles and Automated Vehicles on State and Local Transportation Agencies. Task 12. Business Models to Facilitate Deployment of CV Infrastructure to Support AV Operations

Connected vehicle (CV) technology will be essential to support the operation of automated vehicles in ways that will generate societal benefits rather than disbenefits. Different jurisdictions will have varying levels of interest in deploying CV infrastructure, based on varying perceptions of the benefits that they will gain from CV systems. Limited availability of CV infrastructure will seriously impede the ability of autonomous vehicles (AVs) to operate everywhere and is likely to deter growth of the market for AVs. How should this problem be addressed, to provide policy frameworks and/or business models that can facilitate widespread deployment of the needed CV infrastructure? The objective of the research is to provide guidance for agency decision-makers to use in evaluating possible business models for their CV investment and policy decisions. The project needs to start from a basis of solid analysis showing the importance of CV technology to enable AV systems to produce societal benefits, and then explore how to deploy the needed CV infrastructure. Task 1. Review and summarize existing authoritative research results to show the differences in traffic flow dynamics (and hence congestion, energy use, and pollutant emissions) associated with AV versus CV automation systems at various levels of automation. Based on these results, estimate the net difference in societal benefits of AV implementation with and without CV capabilities for a variety of representative deployment environments (large and small metropolitan regions, intercity corridors with different traffic volumes, etc.). Assess these separately for infrastructure-to-vehicle (I2V) and vehicle-to-vehicle (V2V) cooperative automation (for which the infrastructure requirements are likely to be substantially different). For cases in which the existing literature does not provide sufficient information about the differences, perform additional modeling studies to produce refined estimates. Note: The U.S. DOT is developing a benefits assessment tool that could be foundational to this effort. Task 2. Define how the requirements for CV systems to support AV operations could potentially be more stringent than they would be for other intelligent transportation systems (ITS) applications, in ways such as: (a) limited tolerance of holes in communication coverage when driving from one jurisdiction to the next; (b) greater availability requirements based on safety and productivity implications of the loss of communications by the AV applications; (c) need for additional data elements beyond the minimum required basic safety message (BSM) Part I data elements that will be required for cooperative collision warnings under National Highway Traffic Safety Administration (NHTSA) regulations; and (d) enhanced cyber security needs. Based on considerations such as these, identify the extent to which AV usage could impact the costs of deploying and/or operating the infrastructure elements of both I2V and V2V cooperative systems. Task 3. Define potential business models for deployment of the CV infrastructure needed to support AV use of CV technology, accounting for public agencies sensitivity about providing others with access to their traffic signaling infrastructure. These could include: (a) combinations of designing, building, owning, operating, and maintaining the CV systems by the public agencies themselves; (b) franchising or contracting out to third parties; (c) offering right-of-way access to third parties in exchange for them providing the CV infrastructure; (d) other forms of public-private partnerships in which the AV industry or AV operators would finance the CV infrastructure costs based on their own direct benefits; (e) relying on cellular infrastructure as available rather than deploying dedicated short range communications (DSRC), considering the potential differences in communication capabilities and system performance as well as costs and responsibilities for the public agencies. Task 4. Based on the findings from the previous tasks, develop recommendations for what actions states should take regarding implementation of both I2V and V2V connectivity infrastructure to support AV operations, addressing topics such as: (a) criteria states should use to prioritize locations for I2V and V2V CV infrastructure deployment and (b) how the CV deployments should be financed (what business models for what operating environments) based on the levels of implementation costs and of societal benefits relative to direct private user benefits.
