The Port Authority of New York and New Jersey has used its truck data for traffic management purposes during highway and bridge/tunnel reconstructions and freighteconomic analysis. Chicago has used its truck data to generate truck activity maps of the Greater Chicago region; truck speed simulation; and modeling the effects of toll facilities on truck route choices within the context of the Chicago regional travel model.

The most common survey method for conducting truck travel surveys in urban areas was the combined telephone-mailout-mailback method. Three urban areas in the country Phoenix, Arizona; Alameda County, California; and Houston-Galveston, Texas - have recently conducted truck travel surveys using the combined telephone-mailout-mailback method.
