Development of Ramp Metering Methodology Based on Individual Vehicle Data

With the advances in the development of wireless communications and detection technology, individual vehicle data are available to control the ramp for maintaining freeway. In the existing ramp metering methodology, the traffic data gathered from the main line detectors are usually used. Aggregated data such as averaged occupancy and speed have been widely used as the key parameters for determining the ramp entering volume. In the paper, the ramp metering methodology based on the individual vehicle data is proposed and evaluated with the microscopic simulation model. Individual vehicle data including vehicle speed were tested and the new ramp metering methodology was proposed. The simulation test bed was installed and the performance of the proposed methodology was compared with the existing ramp metering methodology. It was found that the ramp metering methodology with individual vehicle data successfully worked for improving freeway operation and gave better results on reducing speed variations and increasing average speed in freeway.
