Discovering the Transport detail view

For cancelled transports, Visibility Hub offers all carriers a separate view not only displaying the actual tracked transport but also showing an additional purple line.
​
This purple line maps the GPS data that Visibility Hub received from the allocated vehicle for this transport. With this feature, we want to facilitate the trouble shooting of cancelled transports.
​
The article below focuses on a specific part of cancelled transports which is related to incorrect master data underlying the transport. It will describe:

  1. Prerequisites for successful transport tracking.

  2. Detecting loading and unloading locations.

  3. Good to know

1. Prerequisites for successful transport tracking

  1. A license plate is allocated to the transport.
    ​(Learn here how to allocate)

  2. The allocated license plate receives regular GPS signals.
    ​(Learn more about vehicle management)

  3. The truck enters all (un-)loading locations of the transport so its arrival can be detected and visibility can be switched on and off.

  4. The itinerary of the transport matches the itinerary of the allocated truck or at least the stops specified in the tour are visited in any order.

The error message: The truck route did not match the itinerary, relates to points 3. and 4. which will be described in more detail below.

2. Detecting loading and unloading locations

Around each loading and unloading location there is a set of GPS coordinates that is associated with this location. Visibility Hub smart algorithm can detect based on the GPS signal of the truck if a such a location is physically entered. That will trigger switching visibility on (=starting a tour) or off (=ending a transport).

In reality there are two major problems that can occur if the loading or unloading of a truck cannot be detected:

  1. A wrong truck was allocated to the transport (= the truck never entered the (un-)loading location.
    ☝To check if that happened, open transport details and investigate if the truck took the route as expected an if the purple line entered all loading and unloading locations.
    👩‍🚒To avoid this in the future, make sure the correct trucks are allocated to the transports.
    ​

  2. The truck did not send any GPS signal at the (un-)loading location.
    ☝To check if that happened, open transport details and investigate if there are parts of the route that are not covered by a purple line (= there was no option to detect loading or unloading).
    👩‍🚒To avoid this in the future, report this issue to your GPS provider and ask for a log file that proves that the GPS data as been transmitted. With this document reach out to https://support.transporeon.com and have this problem investigated.

3. Good to know

In practice we know that there can be many reasons, why a truck is driving the route not in accordance to the transport plan. In Visibility Hub we take this into consideration as long as the truck visits the stops that are specified in the transport. Even if the truck services the stops in a different order, the transport will still be tracked.
​
However, if the truck is too far away from any of the stops, it is planned to visit, Visibility Hub will notify with the warning above to protect the privacy of your data.

Please note, the better Visibility Hub knows in which order the truck visits loading and unloading stops, the more accurate will be the calculated ETA in real time. If you see problems here, please reach out to your shipper and discuss together, how the target of correct transports in the system can be achieved.
