Research Description

Connected Autonomous Vehicle (CAV) technologies are making rapid gains in the transportation research and markets. Emerging wireless communication technologies for on-board sensors and roadside infrastructure have the potential for significant benefits in terms of mobility, safety and environmental impacts. With more and more CAV technologies implemented in the field, our facilities started to face a mixed traffic environment with non-CAVs and CAVs at different levels of autonomy. These require facilities to be equipped with devices and sensors to enable the connections. Managed lanes (MLs) have gained interest around the U.S. in freeway facility management as they can regulate demand, and utilize available capacity to make the current facility more effective and efficient. ML facilities are frequently equipped with traffic sensors (i.e., speed detectors, traffic counters), tolling equipment (electronic toll collection) and other technologies, which make them the best facility for the early deployment sites for CAVs.

Additional Supporting Information

Recent research has examined and promoted CAV technology on managed lane systems to increase capacity and reduce congestion, as managed lane systems could be equipped with advanced infrastructure relatively quickly. To maximize the benefits from CAVs, there is a research need to evaluate the implementation of CAV dedicated MLs.
