6.2.5 - Collect Probe Data From Vehicles
This process shall collect environmental and traffic probe data from vehicles. Data quality checks shall be performed on all collected data. The environmental data (such as measured air and surface temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, ALB status, and snapshots of recent events include ALB activations, etc.) and traffic data (e.g., vehicle identifier, vehicle speed, heading and snapshots of recent events including starts and stops, speed changes, etc.) will be sourced from vehicle-based sensors or vehicle control systems. The environmental and traffic probe data will be aggregated by this process with measurements from other vehicles, producing one set of environmental and traffic probe data. Traffic probe data in particular will be additionally aggregated with traffic probe data from electronic toll collection operations and transit vehicle probes. When any of the data is provided in analog form, the process shall convert it to digital form and calibrate it. The process shall provide all of the received information to the ISP Operator Interface process and receive the data collection parameters (to define exactly what data shall be retrieved as a result of each request) from the operator interface process.
