Traffic               cameras in HCM City catch more than 4,000 in act
               HCM CITY —               Cameras have caught 4,208 traffic violators since being posted at               roundabouts and intersections around HCM City on September 10,               with motorcyclists accounting for 81 per cent of the total.
               Police said               46 per cent of violations involve wrong way travelling along               one-way streets. Other violations include speeding, running red               lights and overloading motorbikes with passengers or cargo.
               "Violators               of traffic regulations must be fined heavily and vehicles must be               temporarily seized," said Nguyen Van Dua, Deputy Chairman of               HCM City’s People’s Committee.
               Offenders               received pictures of the violations at their homes; violators have               paid 27.5 per cent of the fines issued, ranging from VND50,000 to               100,000. "This shows the initial success of the city’s new               plan to reduce traffic violations," Dua said at a meeting on               Tuesday in which he reviewed the one-month use of traffic cameras               in the city.
               To step up               the fight against traffic violations further, Dua urged traffic               police and cameramen to regularly patrol small streets, one way               streets and areas with new traffic re-direction plans.
               He said               raising traffic safety and awareness of regulations, while               encouraging people to observe traffic rules, is key to keeping the               streets safe.
               This week,               cameras will be installed in areas where daredevils often organise               motorbike races, and on national highway black spots where there               are a high number of accidents.
               "Fines               will also be imposed on pedestrians and cyclists caught violating               traffic regulations," Dua said.
               The city               People’s Committee approved the instalment of 22 new cameras in               the city’s intersections. This month, the city will invest               VND7.7 billion (US$490,000) to put cameras in operation.
               HCM City’s               authorities are determined to reduce traffic accidents by 40 per               cent this year, using cameras and several other drastic measures.
               The city, as               well as reducing accidents, aims to cut traffic congestion by 50               per cent in specific areas, and get rid of inner city racing.
               "Thanks               to law enforcement and increased driver responsibility, the number               of accidents dropped by 20 per cent in HCM City last month,"               said director of the municipal Transport and Public Works, Ha Van               Dung.
               The National               Committee for Traffic Safety reported 74 fewer road accident               casualties in September than in August. Nearly 1,200 accidents               occurred nation-wide last month, leaving 869 people dead and 963               others injured. — VNS
