Abstract: An apparatus and method for activating an inductance loop vehicle detector is disclosed, wherein a magnet is positioned within a casing and attached to a vehicle. In order to activate the inductance loop vehicle detector, the vehicle, attached magnet, and casing are moved in relation to an induction loop embedded within a roadway. A reaction between the magnet and induction loop causes the inductance loop vehicle detector to register the presence of a vehicle. The casing may be configured to form a separation distance between the magnet and the vehicle to enhance the magnetic field proximal the induction loop.

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.

Abstract: The traffic control system uses global positioning system information from a variety of vehicles, analyzes that information and uses it to provide control signals to traffic control devices. For example, a base station may use information about vehicle patterns and vehicle speeds to control traffic signals, speed limit indicators, and traffic metering lights. In turn, the base station can provide information back to the vehicle about traffic patterns. This enables the driver to make his or her own determination about vehicle patterns. The traffic pattern information may also be used with a GPS navigator to automatically plot a preferred path around adverse traffic conditions.

Abstract: A traffic sensor system for detecting and tracking vehicles is described. The disclosed system may be employed as a traffic light violation prediction system for a traffic signal, and as a collision avoidance system. A video camera is employed to obtain a video image of a section of a roadway. Motion is detected through changes in luminance and edges in frames of the video image. Predetermined sets of pixels (nulltilesnull) in the frames are designated to be in either an nullactivenull state or an nullinactivenull state. A tile becomes active when the luminance or edge values of the pixels of the tile differ from the respective luminance or edge values of a corresponding tile in a reference frame in accordance with predetermined criteria. The tile becomes inactive when the luminance or edge values of the pixels of the tile do not differ from the corresponding reference frame tile in accordance with the predetermined criteria. Shape and motion of groups of active tiles (nullquantanull) are analyzed with software and a neural network to detect and track vehicles.
