Interface: Basic Vehicles - INDOT Field Equipment
Information Flow Definitions
broadcast advisories (Planned)
General broadcast advisories that are provided over wide–area wireless communications direct to the vehicle radio. These analog advisory messages may provide similar content to ITS broadcast information flows, but include no digital data component. Existing Highway–Advisory Radio (HAR) advisory messages are a prime example of this flow.
communications signature (Planned) Selected Comm Solution
Communications from devices on–board a vehicle, including personal devices that are carried into the vehicle, that can be monitored by ITS field equipment to uniquely identify the vehicle. This flow represents communications from Bluetooth device(s) on–board a vehicle that may be monitored by ITS field equipment or any other passive or active communications from the vehicle that can be used to identify a vehicle to support traffic monitoring. This flow specifically covers passive monitoring of vehicle communications. Other information flows cover active communications between ITS equipment on–board a vehicle and ITS field equipment.
