• Abstract:
  Freeway corridors in most of Ohio’s major cities exhibit recurring and non-recurring congestion. Traffic responsive metering is particularly attractive due to its ability to dynamically respond to the inevitable fluctuations in traffic. ODOT has ramp meters in operation on two urban freeway corridors in the state. However, performance of these meters in the field and their efficacy at managing congestion was unknown at the start of this study. This research pursued several objectives: (1) assessing the performance of the current system, (2) ensuring good performance from a traffic responsive metering system, (3) investigating the operation of the coordinated ramp metering system, and (4) work with ODOT to improve the performance of the ramp metering system.
