Struct sim::trips::TripManager

pub(crate) struct TripManager {
    trips: Vec<Trip>,
    people: Vec<Person>,
    active_trip_mode: BTreeMap<AgentID, TripID>,
    unfinished_trips: usize,
    car_id_counter: usize,
    events: Vec<Event>,
}

Manages people, each of which executes some trips through the day. Each trip is further broken down into legs – for example, a driving trip might start with somebody walking to their car, driving somewhere, parking, and then walking to their final destination. https://a-b-street.github.io/docs/trafficsim/trips.html describes some of the variations.

Returns the path to use if successful. Caller is responsible for handling both the success and failure case.

impl TripManager

pub fn cancel_unstarted_trip(&mut self, id: TripID, reason: String)

Cancel a trip before it’s started. The person will stay where they are.

    id: TripID,
    reason: String,
    abandoned_vehicle: Option<Vehicle>,
    ctx: &mut Ctx<'_>
