Public transport [PT]

This model describes a conventional public transport service described by a GTFS (General Transit Feed Specification).

Model description

Operator

The operator ensures a collective transport service which is described by a timetable. It also manages the fleet of vehicles that realise this service.

Service vehicles

Each service vehicle is affected to a set of trips. Trips are described in the timetables, and consist in a series of stops where users can be picked up or dropped off. The behaviour of the service vehicles is summarised in the following flowchart.

Users

This model does not include the simulation of users.
