Research On Traffic Dispersal Scheme And Traffic Impact Assessment For Urban Main Road Water Supply Pipeline Construction

As the city scale,increasing the public infrastructure of form a complete set,after occupying,digging urban road construction projects is increasing,lead to serious congestion,during the period of construction surrounding traffic seriously affect the citizens’ happiness and get feeling,at the same time,some items of scientific and reasonable traffic organization scheme is not reasonable,lead to traffic safety problems during actual construction.Therefore,how to scientific and reasonable assessment of traffic organization scheme and traffic impact is particularly important,to ensure the safety of urban traffic flow,districts,people travel car safety is of great practical significance,and through this article research put forward reasonable and presence with field construction traffic improvement suggestion,help to improve roadway taking-up construction management level,To help relevant departments improve the road occupation construction operation system and documents,refine the guidance of construction site operations,and provide a certain theoretical basis for government decision-making.In this paper,starting from the current situation at home and abroad,the construction content and characteristics of the urban main road water supply pipeline are summarized,and the characteristics and design principles of the traffic relief scheme are elaborated.Combined with the analytic hierarchy process(AHP)and fuzzy mathematical method,the fuzzy AHP is finally selected as the evaluation method of this paper.Secondly,on the basis of clarifying the design objective,design content and data collection method of the traffic relief scheme,the ideas of two relief schemes,Scheme one and scheme two,are put forward.Again,through consulting a large number of literature and consulting professionals,questionnaire investigation,build up in this paper,the fuzzy analytic hierarchy structure model of the target layer,and four criteria and 14 index layer,calculate the factor weights and fuzzy evaluation,and put forward using VISSIM software of microscopic traffic impact assessment,and further analysis of traffic impact of the construction project.Finally,this paper chooses the construction of a main road water supply pipeline of Guangzhou as a case to analyze,and makes two drainage schemes,and uses VISSIM software to conduct simulation evaluation of the drainage scheme.The results show that: after the drainage,the service level of the construction scope is at level C.The structural model of this paper is used to compare and select the relief scheme,and it shows that the score of the second scheme is higher than that of the first scheme.Finally,the traffic relief scheme two is determined as the traffic relief scheme of this project.In order to better guarantee the smooth implementation of construction and ensure the safety of construction,pedestrians and vehicles,this paper proposes to refine the emergency plan,implement the safety technology management measures before and during construction,and use information sharing and release,so as to further improve the management efficiency of road-occupying construction areas.In the actual construction process of the project,the construction effect of Scheme 2 traffic relief scheme is good,and there are no traffic complaints during the construction process,which ensures the successful implementation of the project.Based on hierarchical structure model to evaluate the traffic organization scheme for the urban main road construction provides a good reference value,and in view of the practical engineering,put forward the detailed traffic emergency plan,improve the safety management measures and the use of information sharing and publishing mechanism,to other occupy urban road construction,mining has a great significance.
