Study On Traffic Safety Management Of Freeway Maintenance

At present,the expressway development in our country is developing rapidly,and the mileage of construction has reached the advanced level in construction.With the passage of time,the maintenance work of expressways is more and more frequent.The traffic accidents caused by the maintenance of expressways are on the rise.The expressway maintenance There are traffic safety hazards in operation.The U.S.freeway Traffic Safety Administration believes that autopilot technology can eliminate casualties caused by traffic accidents.Expressway traffic safety management plays a decisive role in the application of science and technology.China's freeway traffic safety management is mainly through traffic order management,traffic accident management,traffic safety to achieve.China's freeway traffic safety management technology has achieved some success,but no progress in the maintenance of traffic safety management.freeway maintenance operations often lead to major traffic accidents.Mainly due to driver's improper driving and maintenance area settings are not reasonable.Analyze the traffic safety management in the maintenance area.The speed limit in front of the maintenance area is an effective way to enhance traffic safety.The speed limit set by the expressway is relatively reasonable.The establishment of multiple speed limit points,through the gradual deceleration to protect the stability of vehicle speed.Through the limit calculation of the maximum capacity of the road under the condition of speed limit,the maximum value of the road traffic volume under the condition of freeway maintenance construction is obtained.Study and maintain the safety zone facilities.The prompt signs,traffic cones,anti-collision barrel layout analysis.Traffic cones and bumper buckets to increase the density of the layout,the guidance of the vehicle,the protection and protection work area enhanced.Reflections of freeway maintenance bucket placed vertebral bucket to a considerable extent there is not enough place.In order to prevent the construction unit traffic cones placed too high,causing the implementation of difficulties.It is necessary to make reasonable adjustments to the placement of traffic cones and obtain reasonablelayout density through experiments.On the maintenance of traffic safety,time,traffic safety management responsibilities.Through two typical cases of mobile maintenance operations traffic safety management and large conservation project traffic organization research.Mobile homework has become the first obstruction of autopilot technology on expressways and explores ways to solve the problems of mobile homework.Summarizes the successful experience and shortcomings of large-scale maintenance operation traffic organization and provides reference for more and more reconstruction work in the future.It concludes that we should make good use of the existing traffic control technology platform to refine local standards for maintenance work,strengthen coordination and cooperation between traffic police and maintenance,improve traffic cone layout,strengthen the guarantee of traffic control,speed limit management in operation areas,add identifiable electronic signals and carry out Traffic information service,sub-lane variable signal control and other freeway maintenance operations traffic safety management countermeasures.
