What a "Bad Trip" Looks Like

A Bad Trip is a trip on a run that deviates from the main road.

To illustrate what a bad trip looks like, consider the following run. Trips 1, 2, and 4 can be picked up (green arrow) and dropped off (blue arrow) on the main road, but Trip 3 requires that the vehicle go off the main road to pick up and drop off the client.

If Trip 1 is removed, the vehicle would still have to detour off the main route to pick up Trip 3. The score of this run, once Trip 1 is removed, could be 8, on a scale of 1-10, where 10 is considered “bad.” By rescheduling Trip 1, the cost could increase to 9. In this case, the score is calculated as:
(RescheduleScore - UnscheduledScore) = (9 - 8) = 1.

However, if Trip 3 is removed from the run, the vehicle can quickly pick up and drop off Trips 1, 2, and 4 without detouring from the main route. The score of this run, once Trip 3 is removed, could be 4. By rescheduling Trip 3, the cost could increase back up to 9. In this case, the score is calculated as:

(RescheduledScore - UnscheduledScore) = (9 - 4) = 5

If the bump cost is set to 4, then Trip 3 would be moved to the Bumped run; Trip 1 and any other trips on the run that score below 4 will not be moved:

Because not all trips can be considered “bad” by looking at a map, the Bad Trip Locator relies on user-defined costing weights that determine the importance of a condition, from 0 to 25, where 0 is considered unimportant and 25 is considered very important, when identifying and rescheduling or unscheduling trips. For a list of costing weights and their descriptions, refer to the Costing Weights section in the PASS System Administrator and User Guide.
