| 20090167563 | INTEGRATED INTERSECTION TRAFFIC CONTROL SYSTEM - This invention relates to an integrated intersection traffic control system. The system comprises a statistic module for creating traffic data of each lane and each direction, an intelligent light control module for creating queuing data of the corresponding lane and direction, a vehicle speed detection module for creating speed data, a snapshot control module for crating snapshot control signals, a light control module for receiving lighting mode control commands from a CPU and switching on/off corresponding light power supply circuits, and a CPU for receiving data from other modules and devices and controlling them. The present invention integrates functions including traffic condition monitoring, traffic light control and punishable vehicle snapshoot. Such an integrated system is more economical and easier to construct and operate. | 07-02-2009 |
| 20090167562 | TRAFFIC LIGHT CONTROL SYSTEM FOR A HIGH FLOW INTERSECTION - The present invention relates to a traffic light control system for a high flow intersection comprising a CCU (Central Control Unit) and a plurality of surveillance cameras for monitoring the traffic condition in the intersection and on the lanes going out of the intersection, wherein the surveillance cameras capture traffic flow images in the intersection and on the outgoing lanes, which are converted by an interface circuit and sent to the CCU for processing, wherein the CCU determines whether an outgoing lane is in congestion according to the processed images, switches and keeps on red lights for corresponding directions when the outgoing lane is determined to be in congestion, and resumes the former lighting mode after the congestion is dissipated. Such a control system may, when an outgoing lane is determined to be in congestion, automatically switches and keeps on red lights of corresponding incoming lanes to prevent waiting vehicles from pulling in the intersection, thereby allowing the congestion to be dissipated. | 07-02-2009 |
| 20090167561 | INTELLIGENT TRAFFIC LIGHT CONTROL SYSTEM - The invention relates to an intelligent traffic light control system comprising a microprocessor, a manual input device, an enforced switching device and an intelligent detecting device, wherein the microprocessor is used for controlling traffic lights, the manual input device is used for inputting control parameters of traffic light to the microprocessor, the enforced switching device is used for carrying a preferentially direct operation. The control system can automatically adjust the traffic light control parameters according to the changes of traffic flow in different directions, thereby increasing the traffic efficiency of intersection of roads and achieving a best control for traffic. | 07-02-2009 |
| 20090115848 | MULTIDIRECTIONAL TRAFFIC IMAGE CAPTURING METHOD AND ELECTRONIC POLICE SYSTEM - This invention relates to a multidirectional traffic image capturing method and an electronic police system. This method adopts forward direction camera and side direction camera to capture images of the traffic condition and can obtain qualified images through regularly adjusting the direction of side direction camera with main control unit. This system is made up of main control unit, forward control unit, forward camera, and side control unit and side camera. The main control unit will analyze, judge if there is a disobeying of traffic lights through lights signal and traffic condition, meanwhile control forward direction camera and side direction camera to capture images. This invention adopts multidirectional image capturing method to obtain the images of violated vehicles, which overcomes the long standing issue of red light glaring, guarantees the quality of the images and is mainly used in the supervision and management of the traffic. | 05-07-2009 |
| 20090115634 | VEHICLE DETECTING SYSTEM BASED ON GROUND SENSE COIL - This invention relates a vehicle detecting system based on ground sense coil, mainly comprising a sense coil and a vehicle detector. The ground sense coil possesses a driving and detecting unit while the vehicle detector has central processing unit (CPU). The drive, the detecting unit and the CPU own separate power supply circuits, there are filter circuits on the input terminal of the CPU and/or on the input terminals of the drive as well as the detecting unit, and common input terminal used to connect external power supply circuit. A voltage regulator circuit can be employed on the power supply circuit of the CPU and will be placed in the same electromagnetic shielding shell with the CPU. This invention has simple structure, is convenient to use and effectively avoids interference of the ground sense coil to the CPU. This invention can be applied on roads or other locations that the vehicles pass to detect the vehicles as well as the traffic condition. | 05-07-2009 |
