National Evaluation of the SafeTrip-21 Initiative: I-95 Corridor Coalition Test Bed, Final Evaluation Report: California Deployment of Portable Traffic-Monitoring Devices

The purpose of this document is to present the findings of the national evaluation of the deployment of portable trafficmonitoring devices (PTMDs) at a variety of locations in California conducted under the USDOT’s SafeTrip-21 Initiative. The California Department of Transportation (Caltrans) tested the use of PTMDs in work zones. During this testing, the USDOT conducted an evaluation to gain an understanding of the technical and institutional issues associated with using these types of devices. The purpose of the evaluation is both to learn how highly portable, temporary traffic sensors with a small footprint can provide real-time traffic conditions in work zones and to determine how that information can be used effectively by State Departments of Transportation (DOT) to improve safety and mobility in work zones. Based on their experience during this test, Caltrans personnel reported that the PTMDs enabled them to focus their activities on the areas that needed the most attention, while still monitoring areas that needed less active involvement. The data gathered during the test helped Caltrans personnel to better understand the queuing activity in and around work zones, and will help them plan work zone activities more efficiently and effectively in the future. Overall, based on the findings from users interviewed about PTMDs, the devices appear to be a cost-effective and flexible means for an agency to remotely monitor traffic conditions.
