Optimal Facility Location WIM data (truck count) Investigated WIM data (2003-2009 and 2010 next quarter): Reliability check for each WIM station based on consistency of operating time periods.

25 Optimal Facility Location WIM data (truck count) Investigated WIM data ( and 2010 next quarter): Reliability check for each WIM station based on consistency of operating time periods. Matching WIM stations to CSFFM network: Estimate OD truck volumes by assuming truck OD routes between freight centroids. Probability of having overlapped WIM locations on truck OD routes. ATRI Truck GPS data Truck GPS Processing: Identifying truck route and trip origins & destinations (trip ends). Matching Truck Trips to WIM stations on highways. Identifying highly overlapped WIM locations by truck routes.
