The determination of the design index for the municipal reconstruction of expressway shall not only consider the relevant factors of the project,but also conduct adaptability analysis in combination with the current road conditions.Relying on the municipal reconstruction project of Fuxing Street in Shijiazhuang City,this paper mainly introduces the setting of road engineering design indicators in the process of municipal reconstruction,and predicts and simulates the traffic volume at the intersection nodes and road cross-section traffic volume of the relevant roads.The design index can adapt to the traffic volume in the future use life and ensure the quality and efficiency of road traffic.
With the development of urban construction,viaduct,as an important means to deal with the relationship of urban traffic,has become an important factor in the process of urban development.However,due to the structural characteristics and natural characteristics of the bridge itself,the design texture of the space under the viaduct is incomplete,the scenery is barren and the place is claustrophobia.In addition,the nearby residents and some designers have insufficient understanding of the space under the bridge,resulting in the monotonous spatial structure and low utilization rate of the space under the bridge,which cannot integrate the existing defects such as urban architecture texture.In order to improve the function,landscape and utilization mode of the overhead and under-bridge spatial structure,this paper takes the design of the space landscape engineering under the North Third Ring Road bridge in Shijiazhuang as the main study case,and combines the spatial design practice of this actual project to study ways and approaches to avoid possible negative effects in the space design under the viaduct,so as to transform the empty gray space under the viaduct into a rich scenery and a place for public activities that is meaningful and meets the needs of citizens'space environment.

This paper takes the municipalization transformation of Fuxing Street in Shijiazhuang as an example,and discusses it from both theoretical and practical aspects.Firstly,it clarifies the historical background of urban road aesthetic design by studying the transformation of urban intention,then discusses the importance of urban road for urban intention construction and the strategy of road aesthetic intention construction,and finally analyzes the practical application of Shijiazhuang combining urban renewal vision with road engineering aesthetic design to realize the aesthetic intention construction of road space.This paper points out that intention construction is the basis of road engineering aesthetic design,and also proposes that the influence of human behavior should be emphasized in aesthetic design,so that the construction and design of urban public space can not only achieve urban renewal,shape urban intention,but also guide users to regulate their behavior and jointly maintain the city image.
Because the existing communication technology restricts the development of the intelligent transportation system,the construction,operation,management and maintenance of the road cost is high,and the data transmission is unstable,which leads to the limitation of data exchange and sharing between regions.At the same time,the gap between the new technology development and the road infrastructure construction seriously affects the road management control.In order to solve the problems existing in road management and control system,this paper applies 5G communication technology to intelligent transportation system through data mining,big data computing,etc.,and provides a strong guarantee for urban roads,highways and other traffic systems in the whole process of"construction,management,maintenance,transportation and service",which can better promote the development of our country's highway traffic speed.Based on the actual needs of the reconstruction project of Fuxing Street in Shijiazhuang,this paper discusses the application of 5G communication technology in the intelligent transportation system,and analyzes the application of 5G communication technology in the road,which provides the model for our country road intelligent transportation system construction.
Xinyuan Expressway currently bears a relatively large traffic load,resulting in poor service levels and frequent congestion,and needs to be modified and expanded.During the construction process,in order to reduce the impact of mixed passenger and freight traffic on the efficiency of traffic flow.Using micro simulation methods to simulate the traffic scenarios of passenger and freight vehicles during the construction period,grasp the characteristics of traffic operation,and provide theoretical basis for the formulation of traffic organization plans during the construction period.Based on the cellular automata model theory and Matlab language,a two-way four-lane basic road section model based on the current ground-level during the construction period of Xinyuan Expressway is established,the influence of trucks on the traffic flow in time and space,flow,average speed and average number of lane changes is analyzed.At the same time,the impact on traffic flow is analyzed when the lanes are divided into functions.Through the conclusion,the management suggestions for the current ground-level traffic-ensured plan during the construction period of Xinyuan Expressway are put forward.

The purpose of this article is to study the planning method of urban greenways within the greenway control area while implementing municipal construction.The purpose is to solve the transition between the red line and the red line in the road area,and to solve the problem of the fragmentation of the urban landscape caused by the original closed expressway.Based on the typical case study of the construction planning of the Fuxing Street and North Third Ring Greenway in Shijiazhuang,by sorting out and analyzing relevant industry norms and regulations,and combining with the reasonable space available within and outside the project's own road area,colleagues have identified the types of greenways and the reasonable scope of greenway control areas,and constructed a reasonable layout plan for greenways through the use of composite greenways,further clarifying the functional positioning of urban greenways.To ensure the diversified functions of greenways and the realization of the multiple functions of greenway control areas,the development and utilization of land along the line are drived,the integrated development of"people road scenery"is promoted,and a certain guidance for the planning strategy of greenways and greenways at the city level is provided.
With the economic development and the increasing convenience of motorized travel,the scale of the city has been expanded rapidly.The original urban fringe has gradually been included in the core area of urban development,and the highway does not adapt to the development of the cities along the line.In order to meet the needs of urban development and realize the functional transformation of highways,this paper analyzes the relationship between highways and urban development,and puts forward two models of municipal reconstruction of highways:highways + urban roads and urban expressways(main roads + auxiliary roads)based on whether to separate transit traffic from urban internal traffic.Taking Shijiazhuang Xinyuan Highway and Shihuang-Shitai Highway as practical cases,this paper analyzes the adaptability of the two models,which shows that the urban expressway(main road + auxiliary road)model is more suitable for highway reconstruction in highly urbanized areas.
