Abstract
A system and method that enables 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.

A method for assisting flow of travelers through an intersection, the method comprising:
- providing a mobile communication device to each traveler in a plurality of travelers, said mobile communication device being configured to transmit its location and direction of travel;
- providing a receiver for receiving said location and direction of travel transmission;
- evaluating said location and direction of travel information to determine if a selected traveler in said plurality of travelers is approaching an intersection along said direction of travel;
- if said selected traveler is approaching said intersection, assigning a priority in a ladder of priorities to said selected traveler for when said selected traveler may go through said intersection, said priority being positioned in said ladder of priorities based on how many travelers in said plurality of travelers are approaching said intersection along a same said direction of travel as said selected traveler;
- and
- altering a traffic signal at said intersection based on said assigned priority.
