Method for providing a typical load profile of a vehicle for a public transport system
First Claim
1. A method for determining a composite load profile of a vehicle, wherein the vehicle is configured to take a plurality of trips along a route, the route defines a plurality of stops, the vehicle pauses at each of the stops for a respective dwell time during each trip along the route, the vehicle defines a maximum passenger capacity, and the composite load profile indicates a composite passenger capacity utilization of the vehicle along the route;
- the method comprising, for each of a plurality of trips along the route;
(a) collecting, with a computing system comprising one or more computing devices and from one or more sensors mounted to the vehicle, first data identifying a time-indexed location of the vehicle along the route during the trip;
(b) estimating, with the computing system and based on the collected first data, (i) a dwell time for each stop and (ii) at least one instance of a maximum load stop, a stop being designated as a maximum load stop at least when the vehicle, during the stop, is at the maximum passenger capacity; and
(c) computing, with the computing system, a load profile for the trip byperforming a local regression procedure in which the route is divided into subsections and capacity utilization of the vehicle between adjacent subsections is represented as a linear function of the estimated dwell times and the at least one maximum load stop;
the method further comprising computing, with the computing system, the composite load profile based on the plurality of computed trip load profiles.

Abstract
A method for providing a typical load profile of a vehicle includes computing dwell times and maximum load stops, wherein a maximum load stop indicates a stop having a largest load on a route for a trip using route information and vehicle scheduling information based on automatic vehicle location data, computing one or more trip load profiles by identifying a load progression rate by performing a local regression procedure dividing the route into subsections such that the loads between adjacent subsections can be represented by a linear function on input of the computed maximum load, the computed dwell times, and maximum load stops, and constraining the identified load progression rate to an admissible value by evaluating the rate load progression with regard to historical dwell times and the computed maximum load stops. The method further includes computing the typical load profile based on load profiles of computed trips.
