Coordinated Traffic Flow Control in a Connected Environment

Research Product Type
Research Report
Some field studies have observed reductions in travel time by coordinating freeway ramps with adjacent arterial signals. To advance the investigation, the researchers propose an integrated traffic management strategy that involves variable speed limit, lane change, ramp metering for freeway traffic flow control, and a traffic-responsive signal control scheme for adjacent traffic light intersections.

Coordinated Traffic Flow Control in a Connected Environment

  • Principal Investigator Petros Ioannou, Ph.D.
  • University of Southern California
This project will investigate how connectivity provided by vehicle to infrastructure (V2I) and vehicle to vehicle (V2V) technologies can be used to develop traffic flow control systems that will enhance mobility and safety, and reduce queues at ramps with positive benefits to transportation efficiency and environment.

Dataset: National Mileage Fee Survey

Research Product Type
Data
This dataset is associated with a study that examines the extent to which public perceptions of mileage fees are guided by misinformation or lack of information using a national, internet-based survey. The research team employs hypothetical voting opportunities to gather respondent support for mileage fees, coupled with educational treatments that address mileage fee fairness, privacy, and costs.
