Project Functional Requirements (Element - Functional Object):

• Commercial Vehicle - Vehicle Basic Safety Communication
• 6: The vehicle shall exchange location and motion information with roadside equipment and nearby vehicles.


• LYNX CAV Field Equipment - RSE Automated Vehicle Operations
• 1: The field element shall check the vehicle's condition to see if it is suitable for operating on automated lanes based on vehicle control parameters (speed, headway, etc.) used by vehicles in those lanes, and once confirmed, shall send control parameters to the vehicle.
• 2: The field element shall provide to the vehicle automated lane changing data based on a lane changing strategy and detailed lane changing parameters (e.g. exactly where, and at what speed the lane change will take place), under center control.
• 3: The field element shall manage the checking in and checking out of suitably equipped vehicles requesting use of automated lanes, and send a record of all requests to the responsible center.


• LYNX Transit Autonomous Vehicle - Vehicle Basic Safety Communication
• 10: The vehicle shall determine the status of host vehicle systems including vehicle speed, heading, yaw, wheelspin, ABS, traction control, and wiper status.
• 6: The vehicle shall exchange location and motion information with roadside equipment and nearby vehicles.


• LYNX Transit Autonomous Vehicle - Vehicle Control Automation
• 1: The vehicle shall monitor the area behind and in front of the vehicle to determine the proximity of other objects to the vehicle.
• 2: The vehicle shall monitor the area to the sides of the vehicle to determine the proximity of other objects to the vehicle to determine if a control adjustment is needed.


• LYNX Transit Autonomous Vehicle - Vehicle Control Warning
• 1: The vehicle shall monitor the area to the sides of the vehicle to determine the proximity of other objects to the vehicle and if a warning is needed.
• 3: The vehicle shall provide position warnings to the driver when an object gets close enough to the vehicle to become a hazard if no action is taken by the driver.


• LYNX Transit Autonomous Vehicle - Vehicle Safety Monitoring
• 1: The vehicle shall collect and monitor data concerning the safety of the vehicle - including, steering, braking, acceleration, emissions, fuel economy, engine performance, etc.


• LYNX Transportation Center - TMC Automated Vehicle Operations
• 1: The center shall remotely control automated vehicle system field elements, by providing lane changing parameters, parameters for determination of vehicle suitability for particular automated lanes, and other control information required for automated highway operation.
• 2: The center shall maintain a log of all automated vehicle check-in and check-out transactions received from the field elements regardless of whether they are successful or not.


• Vehicle - Vehicle Basic Safety Communication
• 6: The vehicle shall exchange location and motion information with roadside equipment and nearby vehicles.
