Service Package Description

This service package provides an alternative approach for surveillance of the roadway network. Two general implementation paths are supported by this service package: 1) wide-area wireless communications between the vehicle and center is used to communicate vehicle operational information and status directly to the center, and 2) dedicated short range communications between passing vehicles and the roadside is used to provide equivalent information to the center. The first approach leverages wide area communications equipment that may already be in the vehicle to support personal safety and advanced traveler information services. The second approach utilizes vehicle equipment that supports toll collection, in-vehicle signing, and other short range communications applications identified within the architecture. The service package enables transportation operators and traveler information providers to monitor road conditions, identify incidents, analyze and reduce the collected data, and make it available to users and private information providers. It requires one of the communications options identified above, on-board equipment, data reduction software, and fixed-point to fixed-point links between centers to share the collected information. Both “Opt out” and “Opt in” strategies are available to ensure the user has the ability to turn off the probe functions to ensure individual privacy. Due to the large volume of data collected by probes, data reduction techniques are required, such as the ability to identify and filter out-of-bounds or extreme data reports.

Maricopa County Department of Transportation AZTech RADS ISP Probe Information Collection This equipment package aggregates and processes traffic probe data collected from equipped vehicles, toll operators, and transit centers. It also collects, aggregates, and processes environmental probe data from equipped vehicles. Probe data may be collected through direct wide area wireless communications with vehicles or through short range communications equipment at the roadside. Aggregated probe data and derived route travel times and environmental conditions information are distributed to other centers and other equipment packages that use the information to support transportation operations and traveler information services.
Maricopa County Department of Transportation AZTech RADS ISP Traveler Data Collection This equipment package collects traveler-related data from other centers, performs data quality checks on the collected data and then consolidates, verifies, and refines the data and makes it available in a consistent format to applications that deliver traveler information. A broad range of traveler-related data is collected including traffic and road conditions, transit data, emergency information and advisories, weather data, special event information, traveler services, parking, multimodal data, and toll/pricing data. This equipment package also shares data with other information service providers.
