Topic:
Driving and Motion as Defined via Veh Performance and HOS
Discussion:
This is how it is currently handled for Vehicle Performance and Driver Information:
*One thing to remember is that the way we are handling driving statuses is changing starting in December 2017.
- A vehicle is deemed to be driving after it has been at rest and vehicle has moved a 1/2 mile.
- A vehicle is deemed not driving if either the vehicle is not moving (i.e. speed is 0) for over 5 minutes, or the engine is turned off (RPM is 0) for a period of 4 seconds.
There are 2 things in play here. Your questions is about how we handle Driving Statuses in Events and Positions. The second item in play here is how we handle Driving in HOS. I wanted make sure you knew there is a difference between the two so I will explain how both of them work since it is important.
This is how it is currently handled for HOS:
- A vehicle is deemed to be driving after it has been at rest and vehicle has moved the distance specified as 'Minimum Drive Distance' in the Web Portal (defaults to 1/10th mile).
- A vehicle is deemed not driving if the vehicle is not moving (i.e. speed is 0) for over 5 minutes.
How Motion is handled for BOTH:
A vehicle is considered to be in motion when speed is above minimum speed threshold.
If the speed data is received from the trucks SAE J1708 or J1939 bus then this threshold is 2 MPH and if using GPS, it is 7 MPH.
Above definition referenced on End of Day Rollup#VehicleMotionVehicleMotion as of 12/12/2016.
