摘要： A video camera is placed so as to overlook vehicles' attitudes at an intersection and in the vicinity of the intersection. Video signals provided by the video camera are sent to the main body of a vehicles movement measuring apparatus. An A/D converting unit in the main body converts the video signals into digital data. Digital data in two frames, one of which is taken a certain length of time after the other, is stored in image memory units. Another image memory unit stores data of an input image including no vehicle image. An image data processing unit performs image processing on the data stored in the image memory units and extracts data about vehicles from the processed data. Information relating to speeds, tracking, etc., of vehicles is output from a data input-output unit. This processing of the obtained image data measures vehicles' movement as the degree of traffic jam or the smoothness of the downstream traffic flow on a road with detection of data regarding vehicles presence or speeds.

摘要： A method for predicting a traffic flow rate at a point on a road to control a traffic light signaling system measures a traffic density on the road to predict a traffic flow rate by utilizing the fact that a velocity of a vehicle on the road is restricted by an interval between successive vehicles, since the traffic density is locally increased when the vehicle interval is not uniform and therefore the spatial mean speed is lowered. This method offers higher accuracy by utilizing a correction coefficient obtained from an actual vehicle distribution, for instance, a coefficient derived from entropy. An apparatus for controlling a traffic light signaling system installed on a point of a road by utilizing this predicting method, thereby smoothing a traffic condition, includes video cameras for picking up images of a traffic condition at an upper stream of an intersection, an A/D converter for converting an analog video output signal into a digital video signal, two sets of image memories for storing digital image data about two scenes imaged by the video cameras at a proper time interval, an image processing unit for extracting moving objects from the images, a data process/control unit for calculating a total number of vehicles within a predetermined area and each space headway, whereby a vehicle distribution pattern is recognized an a correction coefficient is calculated, and an input/output unit for interfacing with the traffic light signaling system installed on the road.

摘要： A device for cracking down on disregard of a traffic signal includes a television camera for imaging a road, on which signal lights are mounted at a cross; a vehicle movement measuring instrument for processing image data coming from the television camera and measures traveling position and traveling speed of each vehicle; a signal state detector for detecting an indication color of the signal lights; and a traffic signal disregarding vehicle detector for detecting a vehicle which has disregarded a traffic signal, based on the traveling position and the traveling speed of the vehicle measured by the vehicle movement measuring instrument and the indication color of the signal lights detected by the signal state detector. The vehicle movement measuring instrument measures the distance from the cross and the speed of the vehicle. In the case where there is a vehicle traveling within the cross, while the signal state detector detects a red indication of the signal lights, it is detected as a vehicle which has disregarded the traffic signal, and a recorder records the traveling state and the registration number thereof.

摘要： The present invention provides vehicle activity data by accurately measuring and collecting traffic information, such as vehicle speed, number of passing vehicles, types such as small size and large size of the vehicles. The invention allows tracing of a vehicle which makes a lane change, avoids influence of a large size vehicle for measurement in an adjacent lane, and provides an approach for obtaining vehicle activity data at night time or in the rain. The apparatus stores video information from a video camera in image memories. The stored current image data and background data are processed by an image processing section to assign identification number for respective individual vehicles. Results of tracing include a position of the front end of the vehicle in a measuring area, a vehicle width, and both end positions of the vehicle are stored in time sequence. A computer calculates speed over one second for respective processed frames on the basis of vehicle position information for a given number of preceding frames, provides weights for respective calculated speeds and performs averaging for deriving an accurate vehicle speed.
