Trips for Medium- and Heavy-Duty Vehicles Across the Six Subregions of the Inland Empire

The research conducted by Kimberly Collins, Ph.D., and her team at the William and Barbara Leonard Transportation Center, California State University, San Bernardino, investigates the traffic patterns of medium- and heavy-duty vehicles (MDHDVs) in the Inland Empire (IE) of Southern California. Their study leverages data from proprietary big data vendors to differentiate between long-haul (LH) and regional short-haul (RSH) trips. The use of big data is aimed to overcome challenges in data collection and analysis, such as reliability and accuracy, to improve regional traffic management and planning.
