  • Patent number: 8947265
    Abstract: A signal or lighting system synchronizes the flashing of multiple signal or lighting assemblies. When one of the assemblies is triggered, it broadcasts a temporally staggered sequence of signals, each signal instructing the receiving assemblies to initiate flashing of their beacons a given countdown time after that particular signal is transmitted. The countdown times of the various signals all count down to the same flashing start time so that the originating and receiving beacons all being flashing at the same time. The temporal diversity of the signals enhances the ability to overcome potential interference as at least one of the signals in the sequence is likely to be received by the destination assemblies.

  • Patent number: 8791837
    Abstract: Traffic signal timing may be altered as a function of determining occluded signal viewing. More particularly, processing units may determine that a view of a traffic signal by a person is obstructed by a vehicle located on a first ingress path to a roadway intersection with a second ingress path. The traffic signal controls the right of way of the first ingress path, and the person with the obstructed view is travelling along the first ingress path toward the intersection and is located behind the vehicle relative to a view sightline of the person to the traffic signal. In response to the occluded view determination, a transition of the traffic signal may be delayed from a current visual display of a proceed signal to a subsequent visual display of a stop signal, until an end of a delay period.

  • Patent number: 7777646
    Abstract: System and method alerting drivers approaching a pedestrian crossing and notifying them of the presence of a pedestrian on the pedestrian crossing or any other accidents-prone road sections. By this, an additional traffic safety measure is provided. The presence of the pedestrian crossing marking is not always sufficient. Thus, the proposed system and method are also directed at providing a forgiving infrastructure for both inattentive drivers and jaywalking pedestrians. The system and method utilize movement and weight sensors to detect a movement upon a pedestrian crossing and its vicinity. After negating a possibility that this movement is caused by a passing vehicle, the system invokes illuminating indicators directed at approaching drivers, alerting them to the presence of a pedestrian on the pedestrian crossing. The system may be calibrated to optimize the detection rate, minimizing false alarm and no detection.

  • Patent number: 7601928
    Abstract: A pedestrian push button that discourages vandals and resists weather-related damage. The plunger is contained in a sleek, solid housing formed by a cup-shaped front cover that overlaps and substantially encloses a shallower, cup-shaped body, to protect the electrical components inside. The body is attachable from the inside to the traffic pole or other support surface, and the cover engages the body by means of a “twist-lock” connection that is hidden from view in the installed device. This reduces the appeal of the push button to vandals while at the same time making it easier for authorized personnel to open the housing for service and repair. The back of the body is contoured to conform to both flat and curved support surfaces, making the push button easy to mount securely regardless of the shape of the support surface.

  • Patent number: 7551104
    Abstract: A method called as a time-differential-ratio method and its apparatus used for intersection traffic control that differentially operates on the traffic so as to change pass-permit direction with traffic status in time is disclosed. The method includes the steps of starting, timing, vehicle-requesting, extra-moving, ratio-moving, and recycling. Unlike a common control method called as macro-estimate control method that forces changeable traffic to follow a given period and direction turn order to pass, which causes lots of stops and wait, a differential operations on the traffic are integrated with a common ratio control method and walker signals. It shows the operating features and the effective characteristic of both micro-time control and macro ratio control, which lets a vehicle arriving first pass first conditionally, is good for real-time arbitrary traffic pattern control, and leads to great reduction of stops and wait.

  • Patent number: 7271739
    Abstract: For traffic routing in a walking zone in public buildings, complexes of buildings and traffic zones, which have a plurality of destinations interconnected by traffic routes there are arranged along the traffic routes continuous visual orientation lines which each are associated to one destination, end at the associated destination and can readily be distinguished from each other. The orientation lines are equipped with univocal indicator features pointing towards the associated destination. It is preferably effected by remote control that the orientation lines are composed of display devices which are selectively activated in sections. Remote control is performed in particular by a central control center via a network to which also the control units are connected, which activate the display devices.

  • Patent number: 6982630
    Abstract: A vibrating push button station to be associated with a standard traffic signal of the kind used to control vehicular traffic at an intersection so that visually impaired pedestrians will be alerted when the pedestrian WALK signal is illuminated after first pressing a push button. The push button station includes an electromagnetic assembly that is adapted to generate a changing magnetic field following the depression of the push button. A magnet coupled to the push button by way of a flexible diaphragm is either pulled towards and repelled or simply released by the electromagnetic assembly as the magnetic field changes. The opposite movements of the magnet relative to the electromagnetic assembly is transmitted to the push button as a vibration so that the hand of a user will receive a tactile indication at the push button when vehicular traffic has been halted.
