Interface: Commercial Vehicles - TxDOT Austin District Connected Vehicle Roadside Equipment
Architecture Flow Definitions
driver log (Planned) Applicable ITS Standards
A daily log showing hours in service for the current driver. The query flow is not explicitly shown.
electronic screening request (Planned) Applicable ITS Standards
Request for identification data to support electronic screening.
freight equipment information (Planned) Applicable ITS Standards
Container, trailer, or chassis information regarding identity, type, location, brake wear data, mileage, seal #, seal type, door open/close status, chassis bare/covered status, tethered / untethered status, temperature, humidity, power, battery levels, brake wear data, and bill of lading/information regarding the cargo/content.
infrastructure restriction warning notification (Planned) Applicable ITS Standards
Notification to vehicle on-board equipment (OBE) that includes vehicle size (height, width, length) and weight as measured by infrastructure sensors, current infrastructure size and weight restrictions, and infrastructure restriction warning message(s) currently displayed on roadside signs.
on-board safety data (Planned) Applicable ITS Standards
Safety data measured by on-board sensors. Includes information about the vehicle, vehicle components, cargo, and driver. The query flow is not explicitly shown.
pass/pull-in (Planned) Applicable ITS Standards
Command to commercial vehicle to pull into or bypass inspection station.
screening event record (Planned) Applicable ITS Standards
Results of CVO electronic screening activity.
trigger area notification (Planned) Applicable ITS Standards
Notification to activate wireless roadside inspection safety data message collection.
unique identifiers (Planned) Applicable ITS Standards
Unique identifiers for the motor carrier, driver, and vehicle. This flow identifies the driver actually operating the vehicle in multi-driver scenarios.
vehicle location and motion for surveillance (Planned) Applicable ITS Standards
Data describing the vehicle's position, heading, speed, acceleration, transmission, steering wheel angle, braking status, size information, and trajectory. This flow represents monitoring of basic safety data ('vehicle location and motion') broadcast by passing connected vehicles for use in vehicle detection and traffic monitoring applications.
vehicle payment information (Planned) Applicable ITS Standards
Information provided for payment of tolls, parking, and other transportation fees including identification that can be used to identify the payment account or source and related vehicle and service information that are used to determine the type and price of service requested. The information exchange normally supports an account debit to pay fees, but an account credit may be initiated where pricing strategies include incentives.
vehicle payment request (Planned) Applicable ITS Standards
Request for information supporting payments. For fee structures that include incentives, the request may support either an account debit or an account credit or reimbursement.
vehicle payment update (Planned) Applicable ITS Standards
Data written to vehicle equipment to support electronic toll collection or parking payment.
vehicle profile (Planned) Applicable ITS Standards
Information about a vehicle such as vehicle make and model, fuel type, engine type, size and weight, vehicle performance and level of control automation, average emissions, average fuel consumption, passenger occupancy, or other data that can be used to classify vehicle eligibility for access to specific lanes, road segments, or regions or participation in cooperative vehicle control applications.
vehicle situation data (Planned) Applicable ITS Standards
This flow represents vehicle snapshots that may be provided by the vehicle to support traffic and environmental conditions monitoring. Snapshots are collected by the vehicle for specific events (e.g., when a sensor exceeds a threshold) or periodically and reported based on control parameters when communications is available. Traffic-related data includes snapshots of measured speed and heading and events including starts and stops, speed changes, and other vehicle control events. Environmental data may include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti-lock brake status, and other collected vehicle system status and sensor information. The collected data is reported along with the location, heading, and time that the data was collected.
vehicle situation data parameters (Planned) Applicable ITS Standards
A request for vehicle situation data that includes parameters used to control the data that is reported and the flow of data reported by the vehicle. This flow identifies the type of data/snapshots that are requested and reporting parameters such as snapshot frequency, filtering criteria (data thresholds for reporting), and reporting interval.
