Beijing Cracks Down on Car Horns With Automated Noise Detectors

Beijing's noisy streets are set to become a lot quieter as the city begins punishing violators of its rarely-enforced car horn ban through the use of automated detectors.

Currently implemented in 20 areas throughout the city, violators caught improperly using their horn will be fined RMB 100 (USD 15).

First unveiled last summer, the automated detectors use a sonar system to accurately pinpoint the specific vehicle that made the offending honk. From there, the detectors use a camera system to record the vehicle's license plate, which authorities will use to track down the owner of the vehicle.

A third system comprising of an LED sign will notify the violating driver in real-time that their offense has been recorded by the automated setup.

The system is said to be so precise that it can identify violators within two seconds as well as distinguish between two vehicles traveling side-by-side.

"Parallel vehicles can also be identified based on their position in each lane; the recognition locator feature can reflect the direction the honks are coming from, so there will be no misjudgment," said Li Jianfeng, deputy director of the Scientific and Technical Information Department of the Beijing Traffic Management Bureau.

So far, the system has been very effective at its job, capturing nearly 30,000 violators during a pilot project that started at the beginning of the year.

By law, horn use is prohibited within Beijing's Fifth Ring Road and near special schools and hospitals except in the case of an emergency. Dating back to 2007, the current ban has been difficult to enforce because it required the presence of a traffic officer to both verify the violation and then immediately issue a ticket.
