Performance Measures Through Wireless M2M Communications

California Department of Transportation District 10 is an urban-rural district composed of three valley counties and five foothill counties. With limited resources available to it, District 10 was looking for a high-quality, low-cost data source to serve multiple performance measurement functions including Transportation Management, Traffic Census, and Traffic Signals and to improve surface transportation efficiency. Working closely with InfoTek Wireless, Caltrans District 10 created a customized solution combining the InfoTek Wizard hardware, its Intelligent Loop Detection Application (ILDA) firmware, and data collector middleware to solve its several identified problems and to provide near real-time performance measurement data. The new platform was able to be implemented at a very low cost; it enabled District 10 to provide near real-time data directly to the Freeway Performance Measurement System, developed in cooperation with the University of California at Berkeley and other partners; it allowed for data sharing with Traffic Census, not previously achievable; it facilitated the capture of much more detailed and extensive traffic data, it made possible the archiving of traffic data; and it provided an upgrade to the Caltrans Automated Warning System (CAWS). Caltrans District 10’s rollout of the InfoTek Wizard platform advances ITS by its use of a cutting edge, bi-directional GPRS intelligent modem for wireless data collection and M2M (machine-to-machine) communication, its ILDA software and middleware for collecting, analyzing and archiving more precise data (including actual speed, occupancy, and classification of individual vehicles on a lane-by-lane basis), and its Web-based, user-intuitive GUI interface—all rolled out over existing infrastructure. Once the new data was in place, it immediately began providing data that helped the Caltrans meet its PLAP (Program Level Action Plan) goals for improving safety and mobility for California’s travelers.
