Method for predicting traffic space mean speed and traffic flow rate, and method and apparatus for controlling isolated traffic light signaling system through predicted traffic flow rate
TL;DR: In this paper, 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 speed rate by utilizing the fact that a velocity of a vehicle is restricted by an interval between successive vehicles, since traffic density is locally increased when the vehicle interval is not uniform and therefore the spatial mean speed is lowered.

Masakazu Toyama,Hasegawa Yuji +1 more
TL;DR: In this paper, a video camera is placed so as to overlook vehicles' attitudes at an intersection and in the vicinity of the intersection and the video signals provided by the video camera are sent to the main body of a vehicles movement measuring apparatus.
Patent
Vehicle activity measuring apparatus
TL;DR: In this paper, the authors presented a method for obtaining 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.
Patent
Device for monitoring disregard of a traffic signal
TL;DR: In this article, 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 vehicle disregarding vehicle detector was used to detect a vehicle which has disregarded the traffic signal.
