Research On Spatial Evaluation System Of High-speed Railway New Area Characteristics Based On Crowd Cognitice Behavior

In recent years,with the acceleration of high-speed railway construction in China,the resources and focus of urban development are gradually shifting to the surrounding areas of high-speed railway.More and more cities expect to complete the urban spatial reconstruction by means of the "space-time effect" of high-speed railway.The new high-speed railway area is becoming an important new urban area in China.At the same time,the new high-speed railway area is positioned as a regional city in planning and design.City portal.Under this background,how to improve the overall image of the new high-speed railway zone has become one of the important issues that need to be solved urgently.At present,there are domestic literature on how to shape the characteristic image of high-speed railway new area,but mostly from the perspective of design,few from the perspective of space users to carry out perceptual analysis;secondly,existing research on the spatial characteristics of the new area,mostly concentrated in the vicinity of high-speed railway station,crowded areas,not the whole new area into the discussion.In addition,the current research mostly carries out one-to-one analysis of specific new area objects,and the conclusions are lack of generality,and few studies analyze the new area space from the perspective of evaluation.Faced with the overall scope of the new area,this paper analyses the space that can promote its portal image to show to the outside world,and defines it as "special space".Then,from the perspective of crowd behavior,it summarizes and analyses the elements of space environment,and then constructs a special space evaluation index system of the new high-speed railway area based on the demand of crowd behavior activities.Finally,through the completion of the project,it is relatively complete.The application of the evaluation system is validated by the example of Shan’s domestic high-speed railway new area,which provides a method for the practical application of the system in the future,as well as ideas and references for relevant research.
