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 method for permitting a target vehicle to safely violate a right-of-way system of rules is described. The method may comprise, amongst other things, providing a roadway system, wherein the movements of vehicles within the roadway system are governed by a right-of-way system of rules; controlling a traffic control system including a plurality of traffic control signals in a manner that causes the plurality of traffic control signals to change in accordance with default control pattern for implementing the right-of-way system of rules; and modifying the default control pattern. By doings so, the method may permit a target vehicle to safely violate the right-of-way system of rules. Similarly, by doing so, the method may prevent a plurality of secondary vehicles from traveling along or through a predicted path of the target vehicle.
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:
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:
A system and device that will notify roadway maintenance workers of an approaching mass transit vehicle and, conversely, will notify the operators and administrators of mass transit vehicles of roadway maintenance workers within the vicinity of an approaching section of track.
Abstract:
A fluid pump (10) has a compression member (12) having a variably-sized compression surface (13b) movable against fluid pressure in a chamber (22). The effective surface area of the compression member (12) decreases in size together with a corresponding cross-sectional area of the chamber (22) from a maximal area at a beginning of the compression stroke to a minimal area at the end of the compression stroke. Using a variably-sized surface area to compress a fluid volume allows obtaining a rapid gain of fluid pressure even for applications in which the compression member (12) is actuated at relatively low frequencies and under the action of relatively small forces.
Abstract:
Systems and methods for system for controlling a traffic grid, the system comprising a traffic grid including a first roadway and a second roadway, the second roadway crossing the first roadway at an intersection; a special transit lane included within at least one of the first roadway and the second roadway, the special transit lane being configured to share both personal vehicular traffic and special vehicular traffic; a detector configured to detect the presence of a special vehicle within a detection zone, which detection zone is formed within the special transit lane in a predetermined area proximate to the intersection; and a signal light proximate to the intersection configured to control traffic traveling through the intersection, the signal light having a controller; wherein the controller controls the signal light to operate in a first mode of operation based, at least in part, on a detection of a special vehicle by the detector within the detection zone.
Abstract:
A system and device that will notify roadway maintenance workers of an approaching mass transit vehicle and, conversely, will notify the operators and administrators of mass transit vehicles of roadway maintenance workers within the vicinity of an approaching section of track.
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.
Abstract:
The design consists of the features of the shape and configuration of the heel portion of the boot shown in the drawings. The portions of the boot shown in the broken lines do not form part of the design.Figure 1 is a perspective view of the boot;Figure 2 is a side view of the boot;Figure 3 is a bottom view of the boot;Figure 4 is a rear view of the boot; andFigure 5 is a bottom perspective view of the boot.
