Systems and methods for detection of travelers at roadway intersections
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.
1. A system for assisting a traveler through an intersection comprising:
a mobile communication device under control of a pedestrian having a path of travel, said mobile communication device being configured to transmit its location and direction of travel;
a receiver configured to receive said location and direction of travel transmission from said mobile communication device;
a processor evaluating said location and direction of travel information to determine if said pedestrian is approaching an intersection of roadways and which roadway of said intersection said path of travel will cross;
if said pedestrian is approaching said intersection, altering a traffic signal at said intersection so as to grant said pedestrian the ability to cross said roadway said path of travel will cross when said pedestrian arrives at said intersection.
2. The system of claim 1 , wherein said mobile communication device only transmits said direction of travel information if said mobile device is in a preselected detection zone proximate said intersection.
3. The system of claim 1 , wherein said direction of travel information comprises the direction that the mobile communication device is moving.
4. The system of claim 1 , wherein said direction of travel information comprises the direction that a mobile communication device is pointed.
5. The system of claim 1 , wherein direction of travel information comprises a direction indicated on the mobile communication device.
6. The system of claim 1 wherein said mobile communication device comprises a smartphone.
7. The system of claim 1 wherein said mobile communication device comprises a wearable computer.
