Vehicle-Traffic Control with Limited Capacity CAVs

All Research Projects, Current ProjectsLeave a comment

Research and Field-Testing of Vehicle-Traffic Control with Limited-Capacity Connected/Autonomous Vehicles Overview Connected and automated vehicles (CAVs) are believed to have great promise for the future of urban traffic control, and much research has been conducted in the past decade on the possibilities CAVs present for improving traffic flow in cities. However, the primary focus has…

Crowdsourcing Parking Data for Micromobility Vehicles

All Research Projects, Current ProjectsLeave a comment

Crowdsourcing Parking Data for Micromobility Vehicles Overview As dockless micromobility services become more commonplace, so too are instances of mis-parked bikes and scooters, and associated complaints from other travelers and residents. Concerns over problems with parking are responsible for delaying or limiting the scale of dockless services in some cities, which limits the utility of…
