Abstract: An external adaptive control system controls a traffic signal at a critical intersection that has a most conflicting volume of traffic among volumes of traffic at intersections in a traffic network. The external adaptive control system determines a plan identifying a guaranteed green light time and a minimum green duration and a period for the plan. The external adaptive control system determines, based on the plan, a non-linear schedule with one or more states corresponding to one or more individual phases with each state having a state start time and a state duration. Queues for individual traffic movements at the critical intersection also may be used to determine the non-linear schedule. The adaptive external control system controls the traffic signal according to the non-linear schedule. The external adaptive control system transmits its plan to one or more other external adaptive control systems for other intersections.

Abstract: The present invention relates to an LED traffic signal light containing numerous LEDs and a voltage compensation circuit which allows the traffic light to operate over a wide range of input power voltages, while generating sufficient light intensity to control traffic at a highway intersection. The voltage compensation circuit achieves these objectives without substantially increasing the power consumption, overall cost, or failure rate of the LED traffic signal light. In the preferred embodiment, the voltage compensation circuit disables or rearranges a first and then a second set of LEDs in the traffic light, as the input power voltage drops below a first and then a second threshold voltage, so that the remaining LEDs will be driven by an increased current and generate a greater overall light intensity than if all of the LEDs were driven by the decreased current that would result from the decreased input power voltage.

Abstract: An backup vehicular traffic control system employs a connector-switch including a normally-closed electrical switch connected in series between a traffic signal and a primary control system. In the event of an emergency condition, such as a failure of the primary control system and/or failure of a primary power source, or in the event of a shutdown condition, such as a shutdown of the primary control system and/or shutdown of the primary power source, a connector is manually connected to the connector-switch. The normally-closed electrical switch is opened when the connector is connected to the connector-switch, disconnecting the primary control system from the traffic signal. Also upon the connection of the connector to the connector-switch, an auxiliary control system coupled to the connector is coupled through the connector and connector-switch to the traffic signal. After being connected, the auxiliary control system assumes control of the time of operation of the traffic signal.

Abstract: A solid state load switching conservation circuit removably connectable with a control output of a traffic control logic circuit and responsive to an actuating input to energize an incandescent lamp from an a.c. power source exhibiting a given voltage level. The switching circuit conserves electrical power consumption and the life span of incandescent lamps and, in this regard, employs a thyristor switch, triac driver, shunting network, voltage level monitoring network, a.c. cycle monitoring network, and processor to provide a soft start form of turn on for the lamps being energized. Subsequent to the completion of soft start control, the conservation approach of the invention then turns to a voltage regulation mode which regulates the voltage applied to the lamp during traffic logic control illumination intervals such that the lamp is energized at an acceptable but lowered RMS voltage to conserve both energy and lamp life spans.

Abstract: A monitoring system for energization of traffic lamps (L 1 . . . L 8), with energy supplied from a common voltage source. Protection is provided so that energization of any one of the lamps is not in conflict with energization of another lamp. The system includes a conflict detection means (CD) having a set of inputs respectively connected to monitor individual lamps so that respective inputs of the set are activated in response to energization of respective lamps. The conflict detection means generate conflict signifying information in response to simultaneous activation of combinations of inputs. A signal group generator (SGG) feeds to the inputs a sequence of data signal groups each simultating a conflict or a non-conflict combination at the inputs. The resultant information produced by the conflict detection means (CD) is checked for correctness by a verification means under common control with the signal generator.

Abstract: A device used in the control of automobile traffic signal systems for maintaining a local time reference during periods when the a.c. power is interrupted. An accurate oscillator such as a crystal controlled oscillator is used to provide a local time reference during power interruptions. The device maintains a local clock in synchronism with the a.c. power when the power is present and maintains the time reference in synchronism with the crystal oscillator during those periods when the a.c. power is absent. Pulse trains at different rates generated in synchronism with the oscillator are combined to achieve these objects.
