Abstract: A system for intelligent transport communication includes at least one transmitter, and at least one in-vehicle mobile receiver for use within a mobile road vehicle. The transmitter broadcasts, by wireless communication, dedicated data for each of a plurality of heading directions of the mobile road vehicle, on a corresponding plurality of multiplexed channels. The receiver receives the dedicated data on one of the multiplexed channels that corresponds to an actual heading direction of the mobile road vehicle. A multiple-redundant vehicle heading direction identification system for use within the mobile road vehicle includes a GPS direction identification system, a multiple digital compass system that identifies a heading direction of the mobile road vehicle based on input from multiple digital compasses, and a central processing unit that selects the heading direction produced by the GPS direction identification system only when an output of the GPS direction identification system is healthy.

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.

Abstract: A method for controlling the movement of vehicles including removing a portable transmitter assembly and a portable receiving assembly from a vehicle, disposing the portable receiving assembly contiguous to an area where at least one vehicle travels, and illuminating at least one indicator on the portable receiving assembly with the portable transmitter assembly for controlling the movement of vehicles. An assembly for controlling the movement of vehicles includes a computer-readable medium.

Abstract: In traffic signal control for setting a green light time to a value between the lower limit time and the upper limit time in real time depending on a traffic volume sensed by vehicle sensors Sa, Sb, and so forth, the upper limit time Gmax is set longer with an increase of a traffic volume on an access road corresponding to a phase in question (Steps T8 and T9). This arrangement is effective for use at an intersection where a traffic volume in one direction is far heavier than in any other direction, and thereby makes it possible to forestall the occurrence of traffic jam (FIG. 6).

Abstract: A collision avoidance system and method for a traffic intersection having a traffic light, which selectively extends the duration of a red light cycle to prevent traffic from entering the intersection during a red light violation. Output from one or more violation prediction image capturing devices is used to provide images showing one or more vehicles approaching the intersection. A violation prediction unit, which is also coupled to a signal reflecting a current light phase of the first traffic signal, receives and processes vehicle location information derived from the images to generate violation predictions for the vehicles approaching the intersection. The violation prediction indicates a likelihood that an associated vehicle will violate an upcoming red light phase of the traffic signal. In response to the violation prediction, a violation predicted signal is provided to a traffic signal controlling traffic intersecting with the predicted violator.

Abstract: 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.
