Abstract:Using conventional methods, it is extremely costly to measure detailed traffic characteristics in high quality spatial or temporal resolution. For analyzing travel characteristics on roadways, the floating car method, developed in the 1920s, has historically been the most used assessment tool. Measuring traffic patterns, such as estimating origin-destination (O-D) matrices, has traditionally required the establishment of cordons with many observers recording license plate numbers which are later cross-referenced. Both applications are very labor intensive because of the need to employ human observers over many hours, meaning that the cost per data point is prohibitive for collecting data for anything besides limited studies.
