Measurement And Application Of Walking-effiency Of District

In the context of the development of globalization,from a certain perspective,The development of motorization is somewhat shocking.Many cities in Europe and America are beginning to realize the importance of the choice of motorized development mode because of the disadvantages brought about by high motorization in Europe and America.At present,China is in motorization mode.On the basis of properly promoting motorization,vigorously developing walking travel is the correct path to avoid the development of disorderly motorization in Europe and the United States.The degree of motorization in China has caused a series of urban problems.Especially the walking network under the direction of walking is gradually eroded by motorized development.However,the construction of walking blocks in our country is still in the initial stage.A large number of studies show that the construction of walking blocks cannot meet the daily travel needs of ordinary residents.If we want to change the direction of motorization by developing walking,it is very important to evaluate the existing walking network.Methods and procedures are described and applied to practical projects.First of all,carry on the basic research and the related research summary.It is considered that the shortcut of walking in a block is the convenience of walking from the starting point to various kinds of daily facilities in the block.Through the analysis of the concept of the shortcut of walking in the block,it is pointed out that the shortcut of walking in the street has the most influence on walking.The two major factors are walking distance and purpose.It is pointed out that there are three kinds of quantitative research methods: walking index measure method,walking connectivity measure method and walking accessibility measure method.It is pointed out that it can be used for reference in the aspects of road network mode,land use mode and daily service facility layout.Secondly,the paper puts forward the measurement model of block walking shortcuts,analyzes the influencing factors of block walking shortcuts,and thinks that the influencing factors of block walking shortcuts mainly include walking purpose,walking distance,walking shortcut rate,etc.Different walking destinations have different probability of causing people to travel,so the goal of walking is quantified as the weight of destination,and the size of walking distance also has an effect on people's willingness to travel on foot.If the walking distance is too large,the walking distance will not occur,so the walking distance will be quantified as the distance attenuation value.The walking shortcut rate represents the ratio of the straight line distance between the starting and ending points to the actual distance,which is used to measure whether the walking path is zigzag or not.So quantifying it as cu,and the walking barrier factor also has an effect on the walking path,Therefore,the equivalent quantification is calculated in the walking distance substitution model.Finally,the walking shortcut rate,destination weight value(a)and distance attenuation value(b)are extracted as the calculation index of the street walking shortcut measurement,and the mathematical model is established.Then,select Sugang block of Shunde District of Foshan City as a case study,carry out field investigation and model measurement evaluation.Through field research,record,comb and evaluate the status quo of walking in the research area.Based on Baidu map database,the actual situation of walking network is verified,calibrated and generated,which is used as the basic data for evaluating the shortcut of block walking.Based on the measurement model of shortcut of block walking,Arc GIS is used as the technical platform.Taking the database of Baidu and Gaude as the data source,the complete calculation flow is established,and the result of calculation and visualization of data is realized.Finally,the evaluation results of the shortcut of walking in Sugang district are obtained.According to the evaluation results of walking shortcuts in the blocks,the updated design of Sugang block is carried out.First,the design strategy of constructing a good walking shortcut block is discussed.In this paper,the design methods of walking network and daily facility configuration are presented,and the guidance method of measuring model for building area renewal design is put forward.
