ISP Probe Information Collection

This equipment package aggregates and processes traffic probe data collected from equipped vehicles, toll operators, and transit centres. 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 centres and other equipment packages that use the information to support transportation operations and traveller information services.
