摘要： Approaches for issuing preemption requests. The boundaries of a geo-window are repeatedly determined based on locations and headings of a vehicle as the vehicle is traveling along a roadway. The methods and systems determine whether or not any one of a plurality of intersections is located within the boundaries of the geo-window in response to changed boundaries of the geo-window. In response to determining that one of the plurality of intersections is located within the boundaries of the geo-window, a preemption request is transmitted from the vehicle to an intersection controller at the one of the plurality of intersections.

摘要： A priority control unit is provided for use with light-based and GPS-based traffic control priority systems. The priority control unit includes a light emitter subsystem that is configured to emit pulses of light. The pulses of light encode a priority request for activating preemption of a traffic signal by a light-based traffic control priority system. The priority control unit also includes a GPS-based subsystem that is configured to transmit a priority request by radio waves. The priority request from the GPS-based subsystem is for activating preemption of a traffic signal by a GPS-based traffic control priority system. A switch is coupled to the light emitter subsystem and to the GPS-based subsystem. The switch simultaneously activates both the light emitter subsystem and the GPS-based subsystem for transmitting priority requests in response to user control. In another embodiment, the priority control unit further includes a broadcast based subsystem for transmitting priority requests.

摘要： Various approaches for a traffic control preemption system that includes a receiver, a light emitter, and control circuitry. The receiver includes a photodetector and circuitry that produces a number of electrical pulses in response to each detected light pulse. For each detected light pulse the number of electrical pulses represents a level of radiant power of the light pulse, and a threshold number of electrical pulses and an activation frequency at which the threshold number of electrical pulses is repeated activates preemption. The control circuitry is coupled to the light emitter and controls the light emitter to emit bursts of light pulses. Each burst includes at least two light pulses and a frequency of light pulses in each burst and a frequency of the bursts cause the receiver to produce at least the threshold number of electrical pulses at the activation frequency and activate the preemption.

摘要： Approaches for managing transit vehicle schedules. The method includes determining a current location and current heading of a transit vehicle by a global positioning system (GPS) module aboard the transit vehicle and communicating the current location and current heading to a computer processor. The computer processor determines a current time and current day, and a trip schedule is selected from a plurality of trip schedules in a database. The selected trip schedule has attributes consistent with the current location, current heading, current time, and current day. The method determines whether the transit vehicle is ahead of the selected trip schedule or behind the selected trip schedule. An output signal indicates whether the transit vehicle is ahead of or behind schedule.

摘要： Approaches for prioritizing multiple candidates for preemption of a traffic signal phase at an intersection are disclosed. Light signals transmitted from light-signaling vehicles approaching an intersection encode priority codes using a first set of values. Radio signals from radio-signaling vehicles approaching the intersection encode priority codes using a second set of values. A set of preemption candidates is determined from the light and radio signals, as well as from network-based requests, and a respective relative priority of each preemption candidate based on the priority code of each preemption candidate is determined. A request output for preemption of the traffic signal phase for a preemption candidate having a highest priority.

摘要： The disclosed approaches for processing traffic signal priority requests include receiving traffic signal priority requests from a vehicle. The number of stopped vehicles at the intersection and on an approach to the intersection is determined in response to receiving each priority request. An activation threshold is computed as a function of an estimated-time-of-arrival (ETA) threshold and the number of stopped vehicles. A vehicle ETA of the vehicle at the intersection is determined in response to each priority request. In response to the vehicle ETA being less than the activation threshold, the priority request is submitted for preemption service processing at the intersection. In response to the vehicle ETA being greater than the activation threshold, submission of the priority request is bypassed for preemption service processing at the intersection.

摘要： Managing traffic signal preemption at a plurality of intersections. In one approach a security level code that specifies one of a plurality of security levels for at least one jurisdiction is input. The security level controls which emitter codes are allowed to preempt traffic signals at the intersections in the jurisdiction. A set of emitter codes for the plurality of intersections in the jurisdiction is determined in response to the security level code. The set of emitter codes is downloaded to a plurality of preemption controllers at the plurality of intersections in the jurisdiction. Each preemption controller accepts a preemption request only if the preemption request contains an emitter code indicated by the downloaded set of emitter codes as being allowed to preempt traffic signals at the intersections in the jurisdiction.
