Improving Motorway Mobility and Environmental Performance via Vehicle Trajectory Data-Based Control

open access: yesIEEE Access, 2020
High cost and relatively low reliability of stationary sensors hinder the wide spread of advanced motorway traffic control measures. In this research, we propose a vehicle trajectory data based variable speed limit (VSL) controller to improve mobility ...
