Mobile event triggering function for transit management system using traffic signal priority
First Claim
1. A mobile event triggering method, comprising:
- detecting an entry of a vehicle into a defined event location;
evaluating a vehicle status with respect to at least one entry criterion;
conducting an event entry action when the vehicle status meets said at least one entry criterion;
evaluating the vehicle status with respect to at least one mobile event criterion corresponding to at least one mobile event;
activating said at least one mobile event when the vehicle status meets said at least one mobile event criterion corresponding to said at least one mobile event;
evaluating the vehicle status with respect to at least one exit criterion; and
conducting an event exit action when the vehicle status meets said at least one exit criterion.

Abstract
A traffic signal control method and system reduces the delay time of a transit vehicle at an intersection by incorporating an automatic vehicle location (AVL) system to trigger a traffic signal priority (TSP) strategy with a chain of mobile events to determine the correct timing, location, conditions, and/or other mobile events that may trigger a TSP action. The traffic signal control can also be used to notify vehicle status in passenger/traveler information systems such as street signs, to monitor the wait time at an intersection or bus stop, and in any application that relates to vehicle entry into a given location and a consequence of actions that may be associated with the location.

19. A mobile computer for use in a traffic signal priority control system, comprising:
-
a storage device containing at least one event definition data block, wherein said at least one event definition data block contains mobile event criteria defining at least one mobile event, and a processor containing an algorithm that evaluates a vehicle status with respect to the mobile event criteria and activates the mobile event if the mobile event criteria are met. - View Dependent Claims (20)

21. A traffic signal priority control system, comprising:
-
a mobile computer having a storage device containing at least one event definition data block, wherein said at least one event definition data block contains mobile event criteria defining at least one mobile event, and a processor containing an algorithm that evaluates a vehicle status with respect to the mobile event criteria and activates the mobile event if the mobile event criteria are met;
a vehicle-mounted device that responds to activation of the mobile event;
a receiving device that responds to the response of the vehicle-mounted device to the activation of the mobile event; and
a traffic signal control that controls a traffic signal based on response of the receiving device. - View Dependent Claims (22, 23, 24, 25, 26, 27)
