Fix a stop's time, and how long you stay there
Vanu works out each stop's time from live traffic. When one has to happen at an exact time, you fix it and the rest of the route adjusts.
The basics
Open the stop

Fix the time

Look at the route

The first stop is the departure. Fixing its time is saying when you set off.
The departure adjusts itself

When you fix more than one
You can fix several stops. Vanu works out the legs between them and, when there is time to spare, leaves it as a wait at the earlier stop — rather than driving the van around with passengers aboard.
Two fixed times

When a fixed time cannot be met, Vanu does not invent it: it shows the real arrival and how many minutes late that is.
During the trip
What you set up shows on the running-trip screen, over the stop you are serving.
How long you have been at the stop

Stops with a fixed time

The time families see during the trip is the van's real arrival, not the fixed time. If you get there early and wait, they see when you arrived.
A default value
If most of your stops take about the same time, set it once instead of filling it in stop by stop.

Pick a time for each kind

This does not touch routes you have already saved, and any stop can still have its own time.
