• Abstract:
  The primary objective of this pilot study was to examine six types of land use of interest to the Louisiana Department of Transportation and Development (DOTD): apartment complexes, urgent care facilities, dollar stores, car washes, drive-thru banks, and drive-thru daiquiri/boil shops. This research aimed to answer six questions: (1) How much variability is there in the trip rates among the sites and throughout the week? (2) Are the trip rates significantly different from ITE, so as to warrant further determination of rates? (3) Is variability with contextual factors apparent? (4) What should be the priority for determining new trip generation rates for use in Louisiana, as evidenced by deviation from ITE and potential impact on traffic planning? (5) Can new micro-radars provide more accurate counts? (6) Can third-party mobility datasets provide accurate count data for computing trip rates? To answer these questions initially, two types of measuring devices were considered: counting cameras, which provide classification counts from video, and forward-firing micro-radar devices. Initial tests with counting cameras at the sites showed they were unsuitable for the selected sites' configuration. The micro-radar devices were used next, and despite some operational issues, they provided a more reliable data source. To ease counting, a computer vision tool based on the YOLO algorithm was developed and applied to recorded video from the sites. Finally, both of the micro-radars and the computer vision tool became the primary tools for data collection.
