Analytical Techniques to Use Historical Probe Data to Assess Platooning Potential on Interstate Corridors
Publication: International Conference on Transportation and Development 2020
ABSTRACT
There are multiple vendors that now provide real-time probe data based interstate speed measurements at sub-1 mile, 1-min fidelity. This paper presents an analytical tool for visualizing interstates traffic conditions to validate congestion identified by the probe data with cameras at select locations. This visualization tool is then applied to the I-70 corridor in Indiana, an important east-west freight corridor. The tool is used to screen, at both a strategic and tactical level, the “platoon-ability” of sections, and time periods on I-70. Case studies are presented that illustrate recurring congestion, congestion associated with crashes, and congestion associated with moving workzones and maintenance operations. The 15-min median speed heat map was recommended as a quick and robust screening tool. A series of simulated trajectories, using 1- min segment speed archives, were used to demonstrate the robustness of this strategy by analyzing the frequency of speed changes greater than 10 mph as well as how often the speeds dropped below 55 mph. The paper concludes with a recommended visualization of median speeds for identifying strategic locations and time periods that platooning may be viable and a recommendation for a 10 mi real-time tactical “look ahead” visualization to identify likely areas of congestion or stopped traffic.
