Preferably, a more sophisticated and superior video detection technique is selected as the traffic flow detection technique of the control system based on the current traffic flow detection technique of the intelligent transportation system. The existing traffic flow detection technology mainly adopts two methods, namely a frame difference method and a background difference method. In view of the fact that a moving target in the background difference method is very sensitive to changes of environmental factors such as illumination intensity, weather and the like, the control system detects traffic flow by adopting the frame difference method. The inter-frame difference method (i.e., frame difference method) is a method for obtaining the outline of a moving object by performing a difference operation on two adjacent frames in a video image sequence, and can be well applied to the case where there are a plurality of moving objects and the movement of a camera. When abnormal object motion occurs in the monitored scene, obvious difference occurs between frames, the two frames are subtracted to obtain the absolute value of the brightness difference of the two frames, whether the absolute value is larger than a threshold value is judged to analyze the motion characteristics of the video or the image sequence, and whether the object motion exists in the image sequence is determined. Compared with the traffic flow detection method adopted by other current intelligent traffic systems, the frame difference method has the defects of low detection precision, easy false detection and missing detection for objects moving at high speed. However, as the vehicle congestion condition, namely the vehicle flow in a slow speed state, is required to be checked, the defect of the frame difference method has less influence on the operation of the control system. And monitoring the traffic flow by the frame difference method (the existing traffic system detection method) and recording corresponding parameters into analysis software.
Preferably, the corresponding software is developed to record the bidirectional traffic flow parameters collected by road monitoring and compare with the software setting parameters, when a certain direction parameter reaches a preset congestion level and the compared result of the opposite traffic flow parameter is smaller than the preset clear level traffic flow upper limit value, the software analysis result shows that the section of isolation belt 1 moves towards the smooth traffic direction, the result is transmitted to the electronic control system, and the system controls the automatic movement of the isolation belt 1.
The specific control mode is as follows
(1) The electronic cameras 9 on the road surface monitor the traffic flow on both sides of the road by the inter-frame difference method, and when a certain direction parameter reaches a preset congestion level and the comparison result of the opposite traffic flow parameter is smaller than the preset clear level traffic flow upper limit value, the software judges that the isolation belt 1 moves.
(2) After the software judges that the vehicle needs to move, the warning lamp 8 is lighted at the end of the section of movement needed in the unobstructed direction to remind the vehicle to the middle road of changing lanes to the roadside lane, and the isolation belt 1 at the center of the innermost lane in the unobstructed direction is vacated for movement.
(3) After the vehicles in the unobstructed direction finish lane changing, the road condition recognition control system collects images to confirm that the lanes are clear, and then the road condition recognition control system controls the isolation belt 1 to move.
(4) The traffic direction indicator lamp prompts the front lane change condition when the isolation belt 1 moves.
(5) The movement of the isolation belt 1 is completed, the number of traffic lanes in the congestion direction is increased, traffic indicator lamps in the congestion direction are changed from forbidden to passing, and the congestion situation in the congestion direction is relieved.
(6) If the traffic jam problem cannot be completely solved by the movement of only the section of the separator 1, the above operations (1) - (5) are repeated for the next section of the movable separator 1.
Compared with the prior isolation belt 1, the invention has the advantages that the motion of the isolation belt 1 is controlled, the unilateral congestion condition of the rush hour is relieved, and the smooth passing of private vehicles in rush hours is ensured.
