Abstract: Use of a mobile user device to identify the individual operating a vehicle, which, either alone or in conjunction with a vehicle control unit (VCU), may be used to establish vehicle priority in connection with traffic control systems. This provides for a system that provides priority for the individual based on their individual and current need for priority, as opposed to providing priority generally for a vehicle.

Abstract: Systems and devices that will notify train system maintenance workers of an approaching vehicle and, conversely, will notify the operators and administrators of train systems of train system maintenance workers within the vicinity of an approaching section of track. Embodiments of the safety systems and methods disclosed herein may use track and direction information and/or LiDAR to assist in determining vehicle positioning and/or speed particularly where there are two or more possible tracks or vehicle paths in close proximity to each other.

Abstract: Systems and methods that allow use of simple priority VCUs (those that can only request an increased priority) to operate in a manner that simulates much more sophisticated schedule-adherence or ETA-type traffic control systems without the need to upgrade vehicle hardware. Instead, tracking of the vehicle, whether provided by other systems or by the VCU operating in conjunction with certain prepared points or zones is used to determine if the VCU equipped vehicle is ahead or behind schedule and operation of the VCU itself is altered to modify the expected arrival time of the vehicle.

Abstract: 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.

Abstract: Systems and methods for requesting modification of traffic flow control systems that combine satellite position navigation systems and dead reckoning technology with secure radio communications to accurately report a vehicle's real-time location and estimated arrival times at a series of signal lights within a traffic grid or at a distant signal light, while enabling signal controllers to accommodate priority requests from these vehicles, allowing for these vehicles to maintain a fixed schedule with minimal interruption to other grid traffic.

Abstract: A satellite positioning location based control and monitoring system for light rail transit systems which enables transit personnel to track vehicle positions, progress and non-vital signals as light rail vehicles travel through their routes while eliminating the capital and maintenance costs associated with embedded light rail transit monitoring systems.
