When traffic is requested via [OptimizeToursRequest.consider_road_traffic] [google.cloud.optimization.v1.OptimizeToursRequest.consider_road_traffic], and the traffic info couldn't be retrieved for aTransition, this boolean is set to true. This may be temporary (rare hiccup in the realtime traffic servers) or permanent (no data for this location).
Sum of the delay durations applied to this transition. If any, the delay starts exactlydelay_durationseconds before the next event (visit or vehicle end). SeeTransitionAttributes.delay.
Sum of the duration of the breaks occurring during this transition, if any. Details about each break's start time and duration are stored inShipmentRoute.breaks.
Time spent waiting during this transition. Wait duration corresponds to idle time and does not include break time. Also note that this wait time may be split into several non-contiguous intervals.
Total duration of the transition, provided for convenience. It is equal to: * * next visitstart_time(orvehicle_end_timeif this is the last transition) - this transition'sstart_time; * * ifShipmentRoute.has_traffic_infeasibilitiesis false, the following additionally holds:total_duration = travel_duration + delay_duration + break_duration + wait_duration.
The encoded polyline representation of the route followed during the transition. This field is only populated if [populate_transition_polylines] [google.cloud.optimization.v1.OptimizeToursRequest.populate_transition_polylines] is set to true.
Vehicle loads during this transition, for each type that either appears in this vehicle'sVehicle.load_limits, or that have non-zeroShipment.load_demandson some shipment performed on this route. The loads during the first transition are the starting loads of the vehicle route. Then, after each visit, the visit'sload_demandsare either added or subtracted to get the next transition's loads, depending on whether the visit was a pickup or a delivery.

Vehicle loads during this transition, for each type that either appears
in this vehicle'sVehicle.load_limits,
or that have non-zeroShipment.load_demandson some shipment performed on this route.
The loads during the first transition are the starting loads of the
vehicle route. Then, after each visit, the visit'sload_demandsare
either added or subtracted to get the next transition's loads, depending
on whether the visit was a pickup or a delivery.
