Studies On The Plan Of Maintaining Traffic Moving In Reconstruction Work Zone Of Highway

Changed as a result of highway capacity expansion project of reducing the region, workers, construction machinery, construction roadside traffic barrier and constitute a dangerous environment the complexity of traffic, construction work zones has become the traffic bottlenecks and accidents source of potential danger. This article on the expansion project in the operation area of traffic safety problems, and make some effective technical measures and management measures to safeguard the smooth operation traffic is diverted to the highway expansion project PAT study to further improve the .First of all, introduced to the expansion of highway operations and the type of definition, according to the highway extension, the impact of road and highway extension data, extension of the operations people, vehicles, roads and traffic flow characteristics conducted a systematic analysis, summed up the expansion of highway operations to the danger of traffic. Secondly, the highway extension in accordance with the characteristics of the operating area of the highway expansion in the operation area warning area, transition area, buffer zone, work area, as well as the termination of the district to conduct a reasonable analysis and calculation of the length of the highway expansion different from the construction phase of the deployment area of operations have been studied; then studied the expansion of highway work zones to safety facilities, especially facilities for temporary security settings, analysis of the security operations of the basic requirements for facilities, the operation area of the traffic signs, traffic marking, temporary isolation facilities, safety facilities, such as night-time construction of facilities set up, different extension of the highway construction zone safety devices operating in detail the layout, the extension of the highway traffic safety facilities operations setting effects Analysis of the evaluation. Then, to study the expansion of the highway to the traffic control operations program. Proposed operating area traffic control, speed control, as well as the safety of operations management approach, developed abnormal weather, night construction, traffic accidents and traffic plans for peak hours, the establishment of the expanded emergency management system during the transport.Finally, theoretical analysis, based on the combination of Westwood widening the highway expansion of bilateral section of the specific circumstances of the construction phase of its operations in different areas to explore PAT program to guide Westwood Expressway Extension Project of the smooth.
