摘要： A traffic light control system which includes two-way communications between a moving emergency vehicle approaching a busy intersection with one or more traffic lights, arranged so that the traffic light control apparatus has stored therein preset patterns of response that temporarily preempt the usual operation of the traffic light and instead provides the most effective method of routing the vehicle through the intersection while redirecting general traffic. As part of the invention, the traffic light control mechanism returns acknowledgement of receipt of instructions to the emergency vehicle. The stored preset traffic patterns may in one embodiment be responsive to human intervention from a dispatching center or to time-of-day conditions. The stored traffic patterns in still another embodiment may be arranged to include a plurality of coordinated intersections. In still another embodiment, the traffic light control apparatus may be operated under control of data or voice transmitted from the emergency vehicle's regular two-way voice communications system to a central, attended control station.

摘要： Traffic signals at an intersection are controlled by one or more controllers of the state/interval type, located in the vicinity of the intersection. One or more remote units that are portable or mobile communicate with the controller via a coded signal to command specific light operations, instruct a secondary controller to take-over light control at the intersection from a primary controller, and to reprogram the operation of the controller on a temporary or permanent basis. The remote units generate a code that must be received accurately by the controller before commands are followed. In order to economically provide such a code, the code generator employs a diode matrix that orders data words and address words and is easily reprogrammed. The traffic signal indicator operation is monitored by the controller both to detect controller error, as by a voltage error resulting from an incorrect controller action, and to detect a non-controller error, as by a current error resulting from a burned out indicator. The controller may take different corrective action depending upon the nature of the error, including switching to another controller. An anti-coincidence logic circuit is connected between a state/interval controller and the light driver and disconnect.

摘要： A system for controlling traffic lights to clear intersections in advance of the approach of an emergency vehicle, in which a directional radio transmitter and antenna are provided on the vehicle, which transmits one or the other of two selected coded signals in the direction of movement of the vehicle. An omni-directional radio antenna and receiver are positioned at the intersection to receive the radiated signal from the vehicle approaching that intersection. The first coded signal includes a first pair of frequencies, and the second coded signal includes a different pair of frequencies, which are decoded by two similar pairs of filters. The signals cause a sequence of events including a closing of an interrupter relay which opens all circuits leading from the traffic light controller to all of the traffic lights, and controls the closing, alternately, of two sets of selected circuits, to apply power alternately to two selected sets of traffic lights.

摘要： Priority is given to the movement of buses at intersections controlled by traffic lights, by lengthening the duration of the green lights on the street on which the bus approaches the intersection, and shortening the duration of the red lights, not only in response to the presence or absence of the bus, but also in accordance with the total amount of traffic on that street and the cross street. For each of the streets on which buses travel, there are provided "mini-green" programmer wheels which permit display of the green for two time periods of minimum duration on the relevant street, one time period corresponding to flowing traffic and the other to non-moving traffic. On each street where buses travel, there are also "time extension" programmer wheels, which permit setting of two time extensions of the duration of the green light on the associated street, again for flowing traffic and for non-moving traffic. Each bus street also has "maxi-green" programmer wheels to permit setting of a maximum green time on the associated street. And for each street on which buses do not travel, there are "mini-green" programmer wheels which permit setting of two minimum duration times of the green light for flowing and for non-moving traffic.

摘要： Signal recognition circuitry provides a control signal which is initiated following the receipt of successive input signals provided they are spaced less than a first duration apart and have been received for at least a second duration with such control signal continuing for at least a third duration. A first pulse generator is controlled by the input signals and is used to assure that the spacing between pulses is proper by producing a pulse if the spacing is improper with such pulse being used to inhibit operation of a second pulse generator used to measure the second duration. The second pulse generator controls operation of a switching circuit and operation of a third pulse generator. If the second duration is satisfied, a pulse is provided by the second pulse generator causing the switching circuit to provide the control signal. The third pulse generator begins operation after the pulse has been provided by the second pulse generator and connects with the switching circuit to terminate the control signal in response to a pulse produced by the third pulse generator when it has been operating for said third duration.

摘要： An additional light bulb arranged in each red or yellow lamp of a traffic light is energized through a radio-operated switch by an approaching emergency vehicle. The switch also interrupts the normal intermittent current supply to the red, yellow, and green lamps. Movement of the emergency vehicle is facilitated by the stopping of all traffic along its route not only in transverse directions, but also in the direction of movement of the vehicle and in the opposite direction.

摘要： A control device included in each vehicle composing a vehicle group predicts a vehicle state of a subject vehicle before a traveling regulation point based on speed information of the subject vehicle, light color information of a traffic signal, and distance information between the subject vehicle and an entrance of the traveling regulation point. Based on the vehicle state, it is determined whether a vehicle of which the vehicle state corresponds to an unenterable state is included in the vehicle group. The unenterable state indicates a state where the subject vehicle cannot enter the traveling regulation point before the traffic signal is changed to the yellow light when its speed is maintained at a current speed. When it is determined that the vehicle in the unenterable state is included in the vehicle group, the subject vehicle is controlled such that it does not enter the traveling regulation point.
