In the project, University of South Florida researchers explored a new approach to developing truck traffic data by exploiting truck GPS data obtained from truck companies through a joint venture of the American Transportation Research Institute (ATRI) and the Federal Highway Administration (FHWA). Many companies use GPS to monitor their trucks locations, potentially providing data about truck movements with unprecedented scope and detail. However, the desired measures do not flow automatically from the data, and sophisticated procedures are required to condition the data and then to perform the needed calculations. |
