Societal Challenges of Connected and Automated Vehicles

Journal of Intelligent Transportation Systems

Connected and automated vehicle (CAV) systems will potentially bring many changes to urban and interurban mobility.  Integrating CAV technologies within the traditional road environment interacting with the different road users leads to important research questions, since their potential on shared mobility, the reduction of traffic congestion, energy use efficiency, pollutant emissions and noise reduction is still unclear. Therefore, there is a need for detailed and accurate studies on the estimation on the effects of CAV technologies on transportation externalities.

Moreover, predictable short to medium-term market penetration of CAVs will influence the performance of the road transport system in terms of congestion, energy consumption and pollutant emissions. Anticipating changes in travel demand and mobility patterns due to market penetration of CAVs is important. For example, statistical analysis to determine the key factors that can change mobility patterns in the future are needed. Different scenarios of CAVs market penetration need to be realistically simulated. Advances in strategic decisions of route selection by users and operational eco-driving decisions by system managers need to be assessed, in order to support the emerging and new mobility eco-system designed to enhance mobility and reduce the overall system impacts.

Several stakeholders from the government, industry and academia have invested resources to work on topics related to CAVs.  Additionally, a large number of auto manufacturers and other transportation service providers are leading the way in developing and introducing new concepts and products. Thus, there is a need to better understand these products and the impacts of CAV technologies.

This special issue will examine societal challenges of connected and automated vehicle systems from a variety of perspectives. Topics of interest include, but are not limited to:

  • Energy and environmental implications of CAVs, while accounting for interactions with human-driven vehicles in mixed traffic;
  • Changes needed in traffic, emissions and noise models for accurate estimation of vehicle impacts with CAVs;
  • Effects of connected and automated vehicles on land use and urban mobility;
  • The importance and analysis of big data collected from CAVs to address vehicle impacts;
  • Robust pilot studies with CAVs and their environmental impacts;
  • Energy and emissions warnings to drivers under a CAV environment;
  • Changes in mobility decisions/habits under a CAV environment;
  • Effect of CAV systems on traffic management, accounting for recurrent/non-recurrent congestion conditions;
  • Road pricing planning in a CAV environment;
  • Real-time traffic management in a CAV environment;
  • Intelligent network flow optimization for improved transportation system performance, energy use and environmental impacts;
  • Multi-objective assessment of different impacts of transportation systems in the presence of CAVs;
  • Identification of emissions and noise hotspots, according to different market penetration scenarios of CAVs and human-driven vehicles;
  • Effect of CAVs on the equity of transportation system accessibility.
