| China's highway in the last century since 90 s began to build,has been rapid development,but also the traffic load under the continued growth of the pressure,with the passage of time,the volume increased,the increasing traffic flow,the expressway itself and its supporting facilities are different degrees of wear and aging in Expressway the use of strength greatly reduced will affect the rapid development of social economy in china.So far,a considerable number of expressways across the country have reached the stage of expansion.These expansion activities based on the construction of expressway extension of road construction,will stimulate the construction work accidents and traffic accident frequency,serious impact on road safety operation and serious consequences caused casualties and property losses.Therefore,it is an urgent task to study the optimization of traffic organization in the construction area of the expressway expansion project.This paper tightly combined with the domestic highway status,access to the corresponding references,and the use of field research,using the theory and method of prediction,mathematical statistics,comprehensive analysis,scientific judgment and other related,according to the traffic organization of Lianhuo expressway construction area is optimized through the analysis of capacity and safety characteristics of the construction area of the passage.Analysis of advantages and disadvantages of various traffic organization,division of the construction road section,put forward the principles and methods of prevention of Lianhuo expressway extension traffic organization optimization,and put forward the application area setting method of warning signs;at the same time for the Lianhuo expressway extension section construction chaos,put forward when the construction section of the traffic jam or accident when the traffic flow and safety for the protection of the construction section,should start the emergency Plan;at the same time according to the actual engineering,construction of even Huo highway expansion accident emergency rescue system,the development of rescue and contingency plans.This paper tightly combined with the domestic highway status,access to the corresponding references,understand the research status at home and abroad on the current highway expansion,are discussed in detail in the first chapter of this article,combined with the work experience of a simple review on access to understand about the domestic and foreign research situation of highway expansion;in order to better the thesis deeply Lianhuo on-site research work related to the understanding the Lianhuo highway traffic volume and composition,and in the expansion of road construction will face some type of traffic accident,the theory and method of analysis,forecast,mathematical statistics,and system analysis and other related data through the preparations co llected by combining the quantitative and qualitative analysis,in order to achieve the Lianhuo Expressway Road traffic organization expansion of the construction area are optimized through the analysis of capacity and safety characteristics of the construction area of the passage,and the analysis of the advantages and disadvantages of various traffic organization,division of the construction road section,put forward the method of Lianhuo expressway extension traffic organization optimization principle a nd prevention of traffic accidents,and put forward the method of setting the construction area of warning signs.This paper is of great significance to the traffic organization of Lianhuo expressway extension during construction optimization,and put forward the optimization scheme is feasible for the traffic organization of Lianhuo expressway of the construction area,is conducive to the vehicles in the traffic organization of expressway safety and fast through the construction area of the safe and effect ive,but also will have a major impact on Lianhuo expressway economic benefits. |
