## Abstract

A system and method that enables individual travelers, including pedestrians or individuals on smaller conveyances, to communicate their location and direction of travel to signal light controllers at an intersection, enables traffic networks to receive this communication and output the detected data to the corresponding intersection traffic-signal controller to allow for individuals not in standard motor vehicles to be detected by traffic detection systems and to allow for priority of traveler flow either independent of vehicle use, or based on specifics of the vehicle used.

## Claims

### Claim 1

A method for assisting a loaded mass transit vehicle through an intersection, the method comprising:
transmitting, using a vehicle identifier system, a location and direction of travel of a mass transit vehicle;
a plurality of mobile communication devices communicating with said vehicle identifier system that travelers associated with said mobile communication devices are on said mass transit vehicle;
receiving at a receiver said location and direction of travel transmission;
evaluating said location and direction of travel information to determine if said mass transit vehicle is approaching an intersection;
if said mass transit vehicle is approaching said intersection, assigning a priority to said mass transit vehicle for said mass transit vehicle to go through said intersection, said priority increasing for each traveler on said mass transit vehicle; and
altering a traffic signal at said intersection if said assigned priority is above a threshold number of travelers.

### Claim 2 (depends on 1)

The method of claim 1, wherein said vehicle identifier system only transmits said direction of travel information if said vehicle identifier system is in a preselected detection zone proximate said intersection.

### Claim 3 (depends on 1)

The method of claim 1, wherein said direction of travel information comprises the direction that the mass transit vehicle is moving.

### Claim 4 (depends on 1)

The method of claim 1, wherein said mass transit vehicle is a bus.

### Claim 5 (depends on 1)

The method of claim 1, wherein said mass transit vehicle is a light rail train.

### Claim 6 (depends on 1)

The method of claim 1, wherein said mass transit vehicle is a car pool vehicle.

### Claim 7 (depends on 1)

The method of claim 1, wherein said mobile communication device comprises a smartphone.
