Title:Evaluation of Non-Intrusive Traffic Data Technologies
End Date:April 2009


Obtaining accurate and timely traffic data is essential to successful transportation operations/planning projects. Traffic detection technologies can generally be classified into two groups: intrusive and nonintrusive. Intrusive detection technologies are installed on/within the roadway, which require lane closures. Using this type of technology is inherently more hazardous and is generally more time consuming, especially for temporary traffic data collection. Non-intrusive traffic detection technologies are deployed adjacent to the roadway and require minimal (if any) interaction with traffic flow. These types of detection technologies do not require any lane closures, which results in a safer environment.

The Advanced Traffic Analysis Center (ATAC) has acquired several radar-based traffic detectors (non-intrusive) and will evaluate their performance for the North Dakota Department of Transportation (NDDOT), specifically for use as temporary data collection devices. The main objective of this study is to determine the applicability of using radar-based sensors to support the NDDOT traffic data collection efforts. These sensors would be used primarily as temporary, portable data collection devices, so ideally they would be deployed with minimal resources.
