Identifier of the agent (given in the input files).
selected_alt_id
Integer
No
Identifier of the alternative.
expected_utility
Float
No
Expected utility, or surplus, from the alternative-choice model. The exact formula and interpretation depends on the alternative-choice model of the agent.
shifted_alt
Boolean
No
Whether the agent selected alternative for the last iteration is different from the one selected at the previous iteration.
departure_time
Float
Yes
Departure time of the agent from the origin of the first trip (before the origin_delay), in number of seconds after midnight. If there is no trip for the selected alternative, the departure time is null.
arrival_time
Float
Yes
Arrival time of the agent at the destination of the last trip (after the trip’s stopping_time), in number of seconds after midnight. If there is no trip for the selected alternative, the arrival time is null.
total_travel_time
Float
Yes
Total travel time of the agent for all the trips, in seconds. This does not include the origin_delay and the trips’ stopping_times. If there is no trip for the selected alternative, the total travel time is null.
utility
Float
No
Simulated utility of the agent for the selected alternative, departure time and route.
alt_expected_utility
Float
No
Expected utility, or surplus, for the selected alternative. The exact formula and interpretation depends on the departure-time choice model of this alternative.
departure_time_shift
Float
Yes
By how much the selected departure time of the agent shifted from the penultimate iteration to the last iteration. If there is no departure time for the selected alternative (or the previously selected alternative), the value is null.
nb_road_trips
Integer
No
The number of road trips in the selected alternative.
nb_virtual_trips
Integer
No
The number of virtual trips in the selected alternative.
Identifier of the agent (given in the input files).
trip_id
Integer
No
Identifier of the trip (given in the input files).
trip_index
Integer
No
Index of the trip in the selected alternative’s trip list (starting at 0).
departure_time
Float
No
Departure time of the agent from origin for this trip, in number of seconds after midnight. For the first trip, this is the departure time after the origin_delay.
arrival_time
Float
No
Arrival time of the agent at destination for this trip (before the trip’s stopping_time), in number of seconds after midnight.
travel_utility
Float
No
Simulated travel utility of the agent for this trip.
schedule_utility
Float
No
Simulated schedule utility of the agent for this trip.
departure_time_shift
Float
Yes
By how much the departure time from origin for this trip shifted from the penultimate iteration to the last iteration. If there is no previous iteration, the value is null.
road_time
Float
Yes
For road trips, the time spent on the road, excluding the time spent in bottleneck queues, in seconds. For virtual trips, the value is null.
in_bottleneck_time
Float
Yes
For road trips, the time spent waiting in a queue at the entry bottleneck of an edge, in seconds. For virtual trips, the value is null.
out_bottleneck_time
Float
Yes
For road trips, the time spent waiting in a queue at the exit bottleneck of an edge, in seconds. For virtual trips, the value is null.
route_free_flow_travel_time
Float
Yes
For road trips, the travel time of the selected route under free-flow conditions, in seconds. For virtual trips, the value is null.
global_free_flow_travel_time
Float
Yes
For road trips, the travel time of the fastest route under free-flow conditions, in seconds. For virtual trips, the value is null.
length
Float
Yes
For road trips, the length of the route selected, in meters. For virtual trips, the value is null.
length_diff
Float
Yes
For road trips, the total length of the edges taken during the last iteration and that were not taken during the previous iteration, in meters. For virtual trips, the value is null.
nb_edges
Integer
Yes
For road trips, the number of edges on the selected route. For virtual trips, the value is null.
pre_exp_departure_time
Float
No
The expected departure time for this trip, before the simulation starts, in number of seconds since midnight. This is always equal to departure_time for the first trip of the agent. This can be different from departure_time if the previous trips’ travel times were miss predicted.
pre_exp_arrival_time
Float
No
The expected arrival time for this trip, before the simulation starts, in number of seconds since midnight.
exp_arrival_time
Float
No
The expected arrival time for this trip, at the time the agent departs from the trip’s origin, in number of seconds since midnight. This is different from pre_exp_departure_time if the trip’s actual departure time is different from the one that was predicted before the start of the simulation.
