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, wherein said at least one mobile event is sequenced according to a defined event hierarchy, wherein a given event hierarchy contains a parent event and at least one child event depending on the parent 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.

18. 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, wherein the mobile event criteria is defined according to an event hierarchy where any given event includes a parent event and at least one child event depending on the parent 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 (19, 20, 21, 22, 23, 24)
