vehicle_env_sensor_data_for_traffic

This data flow consists of environmental sensor data from onboard vehicle devices collected at the roadside and is sent to the Process and Store Traffic Data function for further processing to determine environmental conditions. For each vehicle, the data includes unique vehicle identifiers, measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, Anti-Lock Brake System (ABS) status, and other collected vehicle system status and sensor information. Both current data and snapshots of recent events (e.g., traction control or anti-lock brake system activations) may be reported. It consists of the following data items each of which is defined in its own DDE:

list_size
