Application of Global Positioning System (GPS) to Travel Time and Delay Measurements: 2001 Phase

The Global Positioning System (GPS) has been used for the collection of travel time data throughout Delaware. This method proved to be effective and accurate in collecting travel time and delay data for the past five years. The 1997 report describes how the accuracy of the GPS method was tested. Further, the 1998 report contains a step-by-step description of the data collection method. In 2001, data were collected again during peak travel times in both the morning and afternoon.
