Ningbo traffic police invented artifact so that an accident more than a year and a half of peace on the road there is a signal, the driver can pass in the past. Village Road intersection can generally only installed burst flashing lights, the driver of a little problem. How to solve this problem? As a result, Ningbo traffic police Du Zhenning invented a set of early warning system". In April this year, the State Intellectual Property Office awarded the system related invention patents. At the end of the month, it is also a finalist in the national public security organs of the Ministry of public security to carry out reform and innovation competition. Currently, the city of Ningbo has 25 traffic junctions installed this set of car warning system, the effect is significant.

After two years of testing, testing and upgrading, only to come up with this alarm system. Of course, the development process is not smooth. In order to solve the problems such as signal conversion, Du Zhenning specifically went to the science and Technology Department, went to university, to consult experts; in order to make the system sound and flashing lights, he also specifically looking for relevant professional technology company. Last March, the "vehicle warning system" connecting line in Jiangbei two Hong Xing Cun Chen took office for the first time Guangzhuang intersection. Du Zhenning told reporters that this intersection was originally an accident prone, because traffic is small, the passing speed, but accident prone, after nearly two years, only the accident took place on 2, 1 fatalities.
