  • Patent number: 10198943
    Abstract: Embodiments describe new mechanisms for signalized intersection control. Embodiments expand inputs beyond traditional traffic control methods to include awareness of agency policies for signalized control, industry standardized calculations for traffic control parameters, geometric awareness of the roadway and/or intersection, and/or input of vehicle trajectory data relative to this intersection geometry. In certain embodiments, these new inputs facilitate a real-time, future-state trajectory modeling of the phase timing and sequencing options for signalized intersection control. Phase selection and timing can be improved or otherwise optimized based upon modeling the signal's future state impact on arriving vehicle trajectories. This improvement or optimization can be performed to reduce or minimize the cost basis of a user definable objective function.

    Abstract: Provided are a server and a system that are capable of generating road traffic information on traffic congestion in a more appropriate manner, considering actual road traffic conditions. If a vehicle speed V falls below a first reference speed V1 and then exceeds a second reference speed V2 (>V1), then a traffic congestion situation is estimated based on an inference that the vehicle is highly likely to have escaped from traffic congestion. To estimate a traffic congestion situation, it is required that a situation in which the vehicle speed V exceeds the second reference speed V2 continue for a second specified distance or more or for a second specified time T2 or more.

  • Patent number: 8842022
    Abstract: A traffic control sensor system which provides outputted signals to a receiving traffic control system to assist the traffic control system in making real-time informed green light decisions. Such signals received by the traffic control system include calls for a green light for monitored traffic lanes approaching an intersection. The traffic control sensor system employs various techniques to reduce the number of vehicles that are dropped or occluded. A vehicle is considered to be dropped or occluded whenever the traffic control sensor system first detects the vehicle entering a user defined zone within the approaching lanes to the intersection, and then fails to detect or monitor such vehicle exiting the user defined zones. Occlusion or dropping may occur whenever a sensor is malfunctioning, certain environmental conditions are present, or during any time the sensor's detection signal is interrupted such as from cross traffic entering the monitored intersection.

  • Patent number: 8373578
    Abstract: A wireless head for a traffic preemption system. Implementations may include one or more optical receivers adapted to identify an optical signal transmitted by an optical transmitter included in a vehicle preemption unit mounted to a vehicle and one or more head radio transceivers adapted to identify a radio signal transmitted by a vehicle radio transceiver included in the vehicle preemption unit. A head radio frequency (RF) modem may also be included adapted to transmit one or more radio signals to an intersection RF modem. The head may be mounted to a traffic support fixture. The one or more optical receivers, one or more head radio transceivers, and the head RF modem may all be operably coupled together within the wireless head. The intersection preemption unit may be adapted to change a traffic light in favor of the vehicle to which the vehicle preemption unit is mounted.

  • Patent number: 8330622
    Abstract: Traffic light installations for producing meta information on the basis of input information about the surroundings of the traffic light installation. The traffic light installation acts as a data pool and can independently reproduce a road section using the information which it has measured or which it has obtained from adjacent vehicles. In addition, the traffic light installation can use the input information to produce meta information which is communicated to other vehicles and thus results in a constant flow of traffic.

  • Patent number: 8279086
    Abstract: A method and system are provided for determining travel time through intersections by assigning an initial position for a virtual probe in the intersection and updating the position and velocity for the virtual probe such that the position and velocity of the virtual probe are determined multiple times from a time when the virtual probe is at an initial position until the time when the updated position of the virtual probe is past a stop line at the intersection. Updating the position and velocity of the virtual probe involves retrieving vehicle detection data and traffic control signal data to determine a distance from the virtual probe to the closer of a stop line and a vehicle in a queue in front of the virtual probe. The length of the queue is determined using the intersection of two shockwaves.

  • Patent number: 8269654
    Abstract: A flashing beacon may include a signal unit, a control unit associated with the signal unit, a solar panel or collector, and an activation device that may all be mounted or otherwise positioned on a post of a roadway sign. Light units associated with the signal unit may be programmed to flash on and off in a unique wig-wag pattern. Further, a light bar may also be used with the beacon to generate an intense flash of light soon after activation of the beacon as an additional means of grabbing the attention of the operator of a vehicle.

  • Patent number: 8253592
    Abstract: An external adaptive control system and method control a traffic signal controller assembly. The external adaptive control system determines a non-linear schedule with one or more states corresponding to one or more individual phases with each state having a start time and a duration. The external adaptive control system generates presence data for reception by the controller assembly for each state and its associated duration.

  • Patent number: 8248272
    Abstract: The present invention extends to methods, systems, and computer program products for detecting targets in roadway intersections. Transmit antennas transmit signals into a roadway intersection. Receive antennas receive corresponding signal reflections off objects in the roadway. The reflections correspond to two dimensional image data for the roadway intersection. The reflections are conditioned for compatibility with a processor. The processor processes the condition reflections into a two dimensional image of targets in the roadway intersection.

  • Patent number: 8237589
    Abstract: An adjusting system for traffic lights includes a number of image capture units, a processing unit, and a storage system. The number image capture units capture a number of car images. The storage system examines the number of car images to find license plates in each car image, counts the number of the cars, obtains the status of the traffic lights according to the number of the cars, and manages status of the traffic lights correspondingly.

  • Patent number: 8212688
    Abstract: A method of controlling traffic signals at a road intersection, which has a plurality of signal groups, each of which controls at least one direction of traffic within the intersection. The method comprises the steps of obtaining and utilizing traffic data to calculate a current traffic state and the rate of change in the traffic state. The method further comprises formulating at least one action and the duration of the action in response to these calculations. Each action comprises switching at least one traffic signal. One or more policies based on the calculations and the action are resolved. A continuous decision making process is applied to evaluate a reward for the policies resolved and a policy that maximizes the reward is selected.

  • Patent number: 8171290
    Abstract: An authentication system authenticates remotely generated optical control signals. A remote optical emitter transmits an optical control signal from a remote location. A remote authentication device collocated with the remote optical emitter receives an authentication challenge signal and transmits a compatible authentication response signal. A control optical signal processor positioned at a first location receives the optical control signal from the remote optical emitter and generates a control output signal in response to detection of a valid optical control signal. An authentication device is coupled by a real time data communications link with the optical signal processor and with the remote optical emitter.
