In major Chinese cities, huge numbers of bikes compete with growing numbers of cars for
road space, a situation that has led to traffic snarls and congestion. An element of the
Shanghai city government has now obtained what is described as the "world's first
mobile traffic analysis system," a leading edge monitoring device built in Australia
by AARB Transport Research Ltd., that sets a new standard in traffic analysis technology.
The custom-designed vehicle counts and classifies cars, monitors, and analyzes traffic
flow continuously on site. The information collected will be used to prepare strategic
plans to resolve traffic congestion and help ensure that Shanghai has the best possible
road network.
The system features a digital analysis system that automatically monitors traffic using
overhead video cameras mounted on 10-meter (33-foot) masts. One is integral to the
vehicle, while the other is mounted on a trailer unit that can operate independently at a
separate location. Floodlights allow traffic monitoring around the clock.
Video images recorded by the cameras are captured in real time by the software, and up
to 40 detectors can be connected with the screen to provide traffic counts,
classification, flow, and speed.
A sophisticated fuel flow system is included to monitor fuel consumption while an
on-board computer system calculates travel times for specified routes in real time.
