Connected and Automated Vehicles

Connected and Automated Vehicles (C/AV) will present new opportunities and challenges for planning agencies with respect to identifying, prioritizing, and evaluating projects and programs. The resources below are a starting point to help planners better understand C/AV technologies and their potential impact on transportation planning. The FHWA Office of Planning is currently developing a separate web page that will provide a comprehensive look at C/AV and Planning.

Planning Techniques to Address Connected and Automated Vehicles

  • Connected Vehicle Impacts on Transportation Planning: Primer – The primer illustrates how connected vehicles (CVs) may be considered across the range of transportation planning processes and products developed by states, metropolitan planning organizations, and local agencies.
  • Connected Vehicle Impacts on Transportation Planning: Desk Reference – This desk reference is designed to help transportation professionals quickly understand and begin planning for the wide variety of impacts that C/AV technology is expected to have on transportation planning products and processes. It is designed to be a flexible document, and it is not necessary to read the reference cover-to-cover or in order. Readers can simply turn their attention to whichever transportation planning product, planning step or process, C/AV impact, or C/AV application they need further information on.
  • Connected Vehicle Impacts on Transportation Planning: Outreach to Planning Community – This report presents outreach memos on 11 case studies analyzing the impacts of C/AV on various transportation planning products. It provides a high-level account of the most significant or unique impacts of C/AV on particular planning products. The main objective of this research was to comprehensively assess how CVs should be considered across the range of transportation planning processes and products.
  • Connected Vehicle Impacts on Transportation Planning: Analysis of the Need for New and Enhanced Analysis Tools, Techniques, and Data—Briefing for Traffic Simulation Models – This report focuses on the research and activities that will need to take place in order to adapt existing transportation models to include C/AV. It includes a summary of existing data, tools, and products currently used; a gap analysis identifying the limitations of current models in C/AV analysis; and finally, a research plan to target the identified needs and gaps. A current NCHRP Project Task (20-102, Task 9) is comprehensively examining the role of models in planning for C/AV, with a report expected in early 2018.
  • Planning for Operations – Methods developed to support Planning for Operations are relevant to assessing CV projects, especially Vehicle-to-Infrastructure (V2I) investments. Many techniques for assessing Intelligent Transportation System (ITS) investments also apply to CVs.
  • Performance-Based Planning and Programming – Iterating through the steps of performance-based planning and programming is an effective way of responding to rapidly developing technologies like C/AV. Developing a vision of desirable outcomes is essential. The other key element is to develop and use performance measures and data collection to assess progress toward those outcomes. Progress in this case is not just the result of planned investments, but also results from external development of C/AV technologies, and the markets for them.
    • Performance-Based Planning – This website provides an up-to-date overview of FHWA resources related to performance based planning and programming. The website includes guidebooks, case studies, and other resources related to performance based planning and programming.
    • Performance-Based Planning for Operations –This website provides resources for integrating operations into planning and programming. The methods and examples are useful in planning for CVs, but can also help consider AVs.
  • Scenario Planning – Discussing and evaluating possible future scenarios is a key planning activity that can help understand and respond to C/AV technologies. The links offer various resources for using scenario planning.
  • NCHRP 20-102: Impacts of Connected Vehicles and Automated Vehicles on State and Local Transportation Agencies – The objectives of this National Cooperative Highway Research Program are to (1) identify critical issues associated with C/AVs that state and local transportation agencies and AASHTO will face, (2) conduct research to address those issues, and (3) conduct related technology transfer and information exchange activities. 15 different research tasks cover C/AV implications for transit, freight, planning and modeling tools, travel demand, and infrastructure needs, among others.
    • NCHRP Report 845: Advancing Automated and Connected Vehicles: Policy and Planning Strategies for State and Local Transportation Officials – This report assesses policy and planning strategies at the state, regional, and local levels that could influence private-sector automated vehicle (AV) and connected vehicle (CV) choices to positively affect societal goals. The report aims to assist agencies with exploring actions that might increase the likelihood that AV and CV technologies will have beneficial impacts on traffic crashes, congestion, pollution, land development, and mobility (particularly for older adults, youths under the age of 16, and individuals with disabilities).
    • Strategies to Advance Automated Vehicles and Connected Vehicles: Briefing Document – This briefing document is intended for state, regional, and local agency and political decision makers who are framing public policy making for these transformational technologies. The briefing document makes the case for taking action in spite of uncertainties and presents 18 policy and planning strategies that may be useful in advancing societal goals. It is based upon NCHRP Report 845, Advancing Automated and Connected Vehicles: Policy and Planning Strategies for State and Local Transportation Officials.

Connected Vehicles

Connected Vehicles (CV), implemented for example through Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) technology, apply emerging communication and intelligent transportation technologies to improve safety, mobility and efficiency of the transportation system. V2I investments are under consideration today by many planning agencies. Planning techniques for evaluating investments in CV include Planning for Operations, Performance-Based Planning, and Scenario Planning.

Automated Vehicles

Automated Vehicles (AV) are finding their way onto our highways in increasing numbers. There are many uncertainties in what AVs will be able to do, how they will be deployed, and how the public will use them. That makes it impossible to know today whether AVs will call for new investments, or whether AVs will make certain future planned investments obsolete before they are built. In addition, regulatory decisions made outside the planning process will have a significant (and still unknown) effect on how AVs are deployed. Key planning activities include discussing AVs during the planning process, revisiting the discussions regularly during planning document update cycles, and regularly re-assessing what we are learning from pilot projects and on-road testing. Planning techniques that can be used to develop responses to AVs include Scenario Planning and Performance-Based Planning and Programming.

  • Federal Automated Vehicles Policy – This guidance, intended to be updated soon, focuses on four key areas to facilitate the safe introduction and deployment of highly automated vehicles: (1) vehicle performance guidance for automated vehicles, (2) model state policy, (3) NHTSA’s current regulatory tools, and (4) new tools and authorities.
