The purpose of this project was to record the proportion of Canadian vehicles in prominent retail destination parking lots along the I-5 corridor in northwest Washington State. These destinations were located in Blaine, Lynden, Ferndale, Bellingham, Burlington and Marysville. Data collection was executed by dividing the locations into northern and southern zones, with each zone visited by a two-person team following a prescribed route. The teams collected data within specific mapped sections of parking lots by counting the number of cars with Canadian and U.S. license plates with the use of tally counter devices. Additionally, an I-5 overpass is located within each zone in order to look at southbound I-5 traffic at locations both north and south of Bellingham at an identical time of day. Generally, the intent is to visit every site on each of three consecutive days, Thursday through Saturday. On each field day, data collection starts prior to mid-day and is scheduled to finish by late afternoon. The information collected is then compiled in an Excel spreadsheet for further analysis.
