Method and system for optimum bus resource allocation
First Claim
1. A system for optimum allocation of bus resources, comprising:
- one or more buses, each of the one or more buses comprising;
a geo-satellite positioning system (GPS) receiver capable of receiving GPS ranging signals, and a processor that computes bus position and bus attitude based on the received GPS ranging signals; and
a local bus operating center in communication with the one or more buses, comprising;
a transceiver that receives a bus position and a bus attitude for a bus, a database that includes expected bus position information for the bus, and a processor that compares the expected bus position information and the received bus position, and that generates an alert based on a mismatch between the expected bus position information and the received bus position, and determines a corrective action if the bus attitude is unusual, wherein the processor provides reroute information to the bus and computes a required speed for the bus to remain on schedule based on the reroute information.

Abstract
A system and method allow for optimum allocation of buses or similar vehicles. The buses may form a fleet in a metropolitan transportation system. Each bus may be assigned to complete one or more routes during a given time period. Using geo-satellite position system technology, a bus may determine its current location and provide the current location to a local bus operating center or hub. The hub may monitor locations of known obstacles, and may monitor progress of the bus in completing its route. If an obstacle could interfere with route completion, the hub may send an alert and an alternate route to the bus. If a bus cannot complete its assigned route due to the presence of obstacles, the hub may determine that one or more additional buses must be put in service to satisfy required bus routing.

16. A method for optimizing allocation of buses in a mass transit system, comprising:
-
receiving a GPS ranging signal at a bus;
determining a current bus location and attitude based on the GPS ranging signal;
determining an expected bus location based on a designated bus route;
comparing the current bus location and the expected bus location;
if the location comparison indicates a mismatch, issuing an alert;
if the attitude determination indicates an unusual attitude, determining corrective action;
providing reroute information to the bus; and
computing a required speed for the bus to remain on schedule based on the reroute information. - View Dependent Claims (17, 18, 19)
