Abstract

The main objective of this study was to test both intrusive and non-intrusive data collection devices and to provide North Dakota Department of Transportation (NDDOT) with insight into the accuracy of the various data collection technologies and the applicability of the tested devices. All devices were temporarily deployed along with ATAC’s Traffic Data Collection System (TDCS). The TDCS has been upgraded to be able to accommodate not only Autoscope based systems but also the radar-based Wavetronix systems including the SS105 and SS125 sensors. The devices were evaluated based on their accuracy in collecting traffic volumes and classification.
