Changan Street Increases Tail Number Monitor Function

Recently, 13 junction on Chang an Street successively install video detector, which will replace the previous ground Induction coil, intersection of real time monitoring traffic flow, and thus control the traffic lights change, increase the rate of intersection traffic.

Induction coil was destroyed in the overhaul of Changan Street, traffic management departments have completely updated intelligent control system of Changan street lights. In recent days, every night there will be workers in the construction of Changan street junctions. They are standing on the lift engineering car, turning on the lights lamp in the laying of lines, and then install video detector on a light pole. "Every day from 10 o'clock to 6 o'clock in the morning," A master workman said.

Video detectors with the appearance of a normal intersection monitoring cameras almost, principles are taken by turning on the screen, upload back to Headquarters or in the analysis of image on the local host, come to the traffic flow, and then under the lights change direction to how many intelligent vehicle regulation. The street intersection traffic light's computer intellectualization controls this city already to realize. North-South traffic flow in the direction is big, the direction of green time will extend. Conversely, if to vehicular traffic between East and West, North and the red light in the direction of time is extended.

Through the analysis of intersection of vehicle speed and distance, intelligent traffic light timing can make the entire road to form the "green zone", vehicle lights. Yiqian, achieving this intelligence-based, is to rely on underground inductive loop, as long as the vehicle rolled over, coils of electromagnetic induction, and communicate this information to computer systems, computer based on vehicle flow in both directions to real time timing the traffic lights. Facilities at the lights of the city Authority Chief Ma Xuhui introduction, video monitor replacing traditional inductive loop monitor is a monitoring mode conversion (security equipment supply), improve technology integration: first, the video surveillance will be installed at each junction several probes collect traffic flow more informative (security guard equipment), and judgment on the traffic flow will become more accurate and rapid; video monitoring also addresses the issue of vulnerability of coils. Due to the very high temperature of asphalt in summer, coil easily damaged.

And the coil must be planted to cut pavement construction, this installation method is not conducive to large areas of the city used; in addition, video monitor extends the Induction coil also do not have some features, such as image capture, video recording, video in the future may also increase the function of monitoring traffic violations such as tail number limit line, a multi-purpose machines.from:home security equipment
