Intellectualized management of the public transport network
Updated: 2014-06-17
Full intellectualization has been realized in a remote control center for public transportation in Wenjiang District of Chengdu, capital of Sichuan. The whole public transportation in Wenjiang can now be managed from within the center.
In the case of a bus out on the road which hasn't turned on its air conditioner, staff in the control center need only to click a button to turn it on remotely. Also, the remote control system can monitor if any vehicles are traveling too fast.
Wenjiang has installed G-BOS (G stands for GIS, GPS, GPRS; BOS for Bus Operation System) on 74 LNG (Liquid Natural Gas) buses. The remaining vehicles will have G-BOS installed by the end of the year, giving full coverage of the new system within the district.
Real time monitoring standardizes the public transportation system
In the control center, there are nine computers and a big screen. The center carries out seamless shift work, and each public transportation line has a specific member in charge of it.
Type in a license plate number onto the computer and the staff can check on the working status of the driver, the whole view within the bus, road conditions ahead of the vehicle, and the area near the bus door, all of which are recorded by a camera in the bus. This way, the center can check on the drivers’ behavior. Any illegal behavior such as speaking on a phone, or smoking, once detected, will be warned with a notice on the LRD screen in the bus, and also by voice broadcast, letting all the passengers on board know what is going on.
Flexible management ensures a safe transportation
On the center's screen, the staff can also see statistics about each vehicle’s engine speed, brake, or running speed. All these statistics are helpful in detecting problems. If the statistics become abnormal, an alarm will ring in the center. Then the monitoring staff will ask the driver to stop immediately and contact transportation branches to deal with the situation.
With the monitoring system, staff in the center office will often know the vehicle conditions better than the drivers do. For example, they could know how many kilometers the vehicle has run, and when it should undergo maintenance. The control center can also know the actual road conditions and monitor other vehicles in order to change their route flexibly in a traffic jam. Additionally, if a crime is taking place in a bus, the center can view it through the video and call the police as soon as possible, to ensure the safety of the passengers and the drivers.
