Abstract:

A virtual road loop detector has a traffic control system that sends out a signal identifying location and intersection. The traffic control system, used for efficiently switching a traffic control switch, includes an intersection control module that communicates with a vehicle control module in order to determine if the traffic switch changes. The intersection control module is designed to send information regarding the intersection, which provides a virtual loop detector that assists in identify incoming vehicles and relevant switch requests from those vehicles. The virtual loop detector is a theoretical loop and defined by a pre-determined dimension from the intersection. The vehicle control module is provided to identify location and analyze information received from the intersection control system, such as proximity to or within the virtual loop detector. A light switch request may be sent by the incoming vehicle when the vehicle receives signals from the intersection and is traveling toward that same intersection. The intersection control module would then receive any information and light switch requests from the vehicle or any other incoming traffic. An analysis is performed by the intersection control module with regard to various incoming traffic information and requests in order to determine if the traffic light changes from a light schedule.

Abstract:

A method and system of the invention locates an available vehicle parking space. In the method, parked information indicative of a parked condition is stored in a first vehicle. The first vehicle may detect a change in condition from the parked condition to a vacating condition. The first vehicle then communicates the change in condition from the first vehicle to a neighboring searching vehicle and the searching vehicle detects the change.
