Sometimes you know something about the real world that Spare doesn't. This could be a reason that the passenger needs to be in a specific vehicle with a specific driver.
By constraining a trip request to a single duty, you'll now be able to specify the exact vehicle that you want your trip request to go on. If the trip doesn't fit with the current requests on the vehicle, Spare will automatically rematch other requests on the vehicle, as long as those requests still fit their stated trip flexibilities.
This feature is available in our Dispatch Package. Contact your Spare representative to learn more.
