Abstract:

Selecting an appropriate device for collecting accurate traffic data without creating any negative influence on traffic flow can be challenging for a traffic engineer. Understanding the tradeoffs of different data collection methods is a priority in order to conduct a successful data collection effort. This study explored the differences between three non-intrusive ITS sensors using radar technology: iCone, Radar Recorder, and Wavetronix SmartSensor HD (WSSHD) to collect a specific traffic parameter in comparison to the pneumatic road tubes (PRTs). This study compared 408 hours of sensor data along on a rural two-lane road with a posted speed limit of 55 mph and quantified the differences in accuracy of the devices used for collecting speed and volume traffic data. The results showed that the error in detected speeds and volumes for iCone and Radar Recorder in comparison with PRTs were 1.5 percent and 1.4 percent, respectively, and 2.1 percent for the WSSHD. The error in detected volumes for the iCone and Radar Recorder in comparison with the PRTs were 8.6 percent and 7.8 percent, respectively, while for the WSSHD there was no difference from the PRTs. Based on the results, to collect traffic volume data for each traffic lane separately, the WSSHD is recommended. When collecting individual vehicle data is required, the Radar Recorder is recommended. As long as individual vehicle data are not required, the iCone could be a convenient option especially for short-duration data collection and more specifically at work zones where detector placement may be a challenge.
