The invention relates to a traffic signal light intelligent control system and a control method thereof, which belong to the technical field of intelligent traffic; the system comprises four CCD camera heads, a signal processor and a controller; and the method comprises the following steps: establishing a coordinate system and the transformation relation thereof; sequentially carrying out distortion correction, sharpening and perspective transformation on a traffic flow image; extracting edges of a vehicle image and filtering out lane lines and traffic sign arrows in the image; cutting the image; carrying out edge projection for obtaining pixel coordinates which correspond to the queue length of vehicles waiting to pass on each type of lane in each direction under the computer image coordinate system; calculating the actual queue length of the vehicles waiting to pass; obtaining time required for leading all the vehicles on each type of the lane in each direction to pass; and controlling the opening and the closing of a traffic signal light according to the time of leading all the vehicles to pass. The traffic signal light intelligent control system can control the opening time and the closing time of the traffic signal light in a high-efficient and energy-saving manner, thereby providing a scientific information base for realizing the urban intelligent traffic.

The invention belongs to the technical field of traffic management, and relates to a road traffic flow prediction method based on cell phone data. The method comprises the following steps of: dividing the time when the traffic flow is needed to be predicted and monitored during the day into different periods of time; in an observation phase, for each observed day, obtaining the cell phone data ofeach period of time through monitoring cell phone switching quantity among different base stations arranged at the same road section, and monitoring and counting road traffic flow data of each periodof time; calculating a related coefficient between the cell phone data and the road traffic flow data; in a prediction phase, monitoring the cell phone data of each period of time in real time; and predicting the traffic flow data in the current period of time according to the cell phone data monitored in real time and the related coefficient. The road traffic flow prediction method based on the cell phone data can reduce cost and labor power invested in road detection devices, and provides an effective way for implementing intelligent urban traffic and solving problems of traffic jams.

The invention discloses an on-board monitoring terminal.
