Abstract:

Performance measures play a critical role in the operation of Intelligent Transportation Systems (ITS), because they provide feedback to the operators regarding system operations and efficiency. Traffic management systems use archived data, provided by various sensors, as a basis for describing normal conditions and predicting traffic conditions that may be expected at a particular time and place in the highway system. However, one of the primary concerns of ITS data users is how to assess the quality of the data. Although detectors are usually tested immediately after installation, they operate under very difficult conditions and are susceptible to degradation in accuracy or complete failure. Therefore, the development of data quality control procedures to screen erroneous data has become a critical issue. This report proposes a set of quality control metrics for the Indiana Department of Transportation to use for ensuring high quality data is provided by all sensors. The quality control program provides a tool for assessing the quality of traffic data in terms of accuracy and availability and sustaining that quality over time.
