Motion Status provides clarity with regards to the vehicle’s movement summary for a given time period.
For a vehicle with an active device, the system has 5 different motion status defined, as mentioned below:
Moving
Stopped
Idling
Device Offline
Low GPS Connectivity
The motion status of a vehicle is updated in real time, as and when any new data packet is received from the device.
As and when the platform receives a new data packet, the first thing that we do is to identify whether the vehicle is MOVING or not.
If the Device Speed (in the data packet) was greater than equal to 5 km/hr, we consider that the vehicle is MOVING
If the device is less 5 Km/hr, we consider the the vehicle isn’t moving and is hence considered as STOPPED
Once the system has identified that the vehicle is STOPPED, we check whether the IGNITION value received in the data packet to check for instances of IDLING
In reality, it is possible that the vehicle might have stopped at a traffic signal and might not be IDLING in general. To differentiate between such on-ground cases from actual instances of IDLING, we have an ‘Idling Threshold’ input parameter.
The default value of Idling Threshold is 10 mins
Identifying DEVICE OFFLINE motion status
This is based on last reliable data packet received based on device gps time
If the timestamp of the last data packet received is older than the ‘Device Offline Threshold’ (default value is 6 hours) time period (from current time). Then we show this as OFFLINE
The Device Offline threshold is configurable by the user. The configuration can be updated from the general setting option under the Configuration section on the navigation panel.
Identifying LOW GPS CONNECTIVITY motion status
Sometimes due to network or other connectivity issues, the device does send some false or inaccurate data packets.
Each data packet has an input that describes whether the given data packet is reliable/accurate or not.
If during the default ‘Device Offline Threshold’ duration (ie, last 6 hours) the device has only shared unreliable data packets, then we know that:
Device is Online (ie, it has GSM or Internet connectivity)
But since is not sending any reliable location packet, we infer that the device is in LOW GPS CONNECTIVITY region
Note: We don’t consider any data be it gps or sensor etc in such cases.
