Trip Format

Traffic Mode Attribute

Vehicle

field: data.vehicle_attribute	type	description
lane_change_length	float64	distance required to complete lane change: m
min_gap	float64	the minimum distance between the vehicle and the vehicle in front: m

Bike

field: data.bike_attribute	type	description
speed	float64	moving speed of this person if he rides a bike

Walking

field: data.pedestrian_attribute	type	description
speed	float64	moving speed of this person if he walks

Schedules Attribute

Position

Position types	field	type	description
Position.LanePosition	lane_id	int	LaneID
	s	float64	s is the distance from the point on the lane to the starting point of the lane
Position.AoiPosition	aoi_id	int	AOI ID
	poi_id	int	POI ID, needs to be a sub-poi of aoi_id, otherwise the value is invalid

Journey

message types	field	type	description
DrivingJourneyBody	road_ids	list[int]	road sequence from origin to destination
	eta	float64	estimation time of arrival
WalkingRouteSegment	lane_id	int	Lane ID
	moving_direction	MovingDirection	moving direction; 0: unspecified; 1: in the same direction as the positive lane direction; 2: in the opposite direction as the positive lane direction.
WalkingJourneyBody	route	list[WalkingRouteSegment]	the (Lane+direction) sequence from the origin to destination
	eta	float64	estimation time of arrival
Journey	type	JourneyType	0: unspecified; 1: driving; 2: walking
		DrivingJourneyBody	Optional. routing results for driving journey
		WalkingJourneyBody	Optional. routing results for walking journey

Trip

field	type	description
mode	TripMode	trip mode, 0: unspecified; 1: walking only; 2: driving only; 5: Riding bikes if avaible, otherwise walking.
end	Position	destination
departure_time	float64	expected departure time (in seconds), optional
wait_time	float64	the expected waiting time (in seconds), if departure_time is empty, wait_time defaults to 0, optional
arrival_time	float64	expected arrival time (in seconds), optional
activity	string	the activity name of the destination for this trip
routes	Journey	pre calculated routing results

Schedule

field	type	description
trips	list[Trip]	list of trips
loop_count	int	the number of times trips are executed, where 0 represents infinite loops and greater than 0 represents how many times they are executed
departure_time	float64	expected departure time (in seconds), optional. FAQ: Q1-What would happen if both the Schedule and the departuretime of the first Trip were specified simultaneously? A1-only depend on the departuretime of Trip. Q2-What would happen if both the Schedule and the first Trip were specified with wait_time=10 at the same time? A2-the waiting time is 10+10=20
wait_time	float64	expected waiting time (in seconds), if departure_time is empty, wait_time defaults to 0.

Main Attribute

field	type	description
data.attribute.length	float64	length: m
data.attribute.width	float64	width: m
data.attribute.max_speed	float64	max speed: m/s
data.attribute.max_acceleration	float64	max accelaration: m/s^2 (positive value)
data.attribute.max_braking_acceleration	float64	max deceleration: m/s^2 (negative value)
data.attribute.usual_acceleration	float64	usual acceleration: m/s^2 (positive value), required to be less than the max acceleration
data.attribute.usual_braking_acceleration	float64	usual deceleration: m/s^2 (negative value), required to be greater than the max deceleration
data.home	Position	initial position
data.schedules	list[Schedule]	initial schedules
data.labels	dict[string, string]	[can be empty] additional tags (e.g. repair vehicle type -> power grid)
