Determine the latest departure times of stations

[kevinkrueger]

Now, to output our departure times to our stations, we specified "ExactTimeConsiderationAtArrival" in the route calculation. Thereby we got the following error message:
"ExactTimeConsiderationAtArrival mode can not be used if TourRestrictions are requested.".

How can I solve this problem?

Hello Kevin,

in fact this error occurs because we do not compute the break- and rest rules while we create the route from the "reverse angle". Technically this would be possible but in such a case we would start to insert the breaks in the wrong way:
Imagine a driver who is completely refreshed but who needs a break after 4:30 hours.

Forward: based on a refreshed driver in ExactAtStart mode. This structure is what you'd like to get.

With "ExactAtArrival" we would insert the "first" break 4:30 back from the ArrivalTime and so on.

The output route of such an approach would probably display the "early" breaks way too early.

Now in this case I simulated the expected output with an (impossible) combination of "ExactAtArrival" and "Break- and Restrule of a refreshed driver". The first break occurs somewhere after 2:00 hours which is wrong.

What you could do to solve this: Apply an iterative approach

• Perform a ExactAtStart-Routing with a reference time almost as the desired "arrival time".
• Use the output arrival time to determine a "shift" period
• Calculate the route again in "ExactAtStart"-Mode but translate the "start time"

Not the perfect solution but for most cases good enough.

Best regards,
Bernd

PS: This video shows how we flood the network in a unidirectional case (such as ExactAtStart and ExactAtArrival).

quick update... though the following request does not mention "TourOptions" it fails with an

Took me a few seconds to spot the various implicit causes:

• The waypoints contain tourStopOptions.
• The resultFields ask for tourReport="true"
• The resultFields ask for <eventTypes>TOUR_EVENT</eventTypes>

Each one of these triggers the error in this case.
