Research On The Evaluation And Optimization Of Pedestrian Space In The Core Area Of The Capital Based On The Living Circle Of The Elderly Group

With the deepening of the aging population in our country,the daily travel needs of the elderly population are also gradually increasing.The problem between the current situation of pedestrian space and the needs of the elderly is prominent,resulting in contradictions such as space occupation and low level of fitness for the elderly.The pedestrian space and corresponding supporting facilities urgently need to be renovated and upgraded.The life circle is an important basis for dividing the daily travel of the elderly population,and also an important driving force for creating livable travel for the elderly.It is of great significance to conduct a unified evaluation and analysis of pedestrian space and facilities based on the needs and behavioral patterns of the elderly population,combined with the current road situation.This article takes the pedestrian space in the core area of the capital as the research object,pays attention to the physiological conditions and practical needs of the elderly,and from the perspective of the elderly population’s living circle,conducts a scientific evaluation of the current situation of pedestrian space for the elderly population,in order to provide reference for the future transformation and improvement of pedestrian space in the core area of the capital.This article extracts and analyzes the current construction status and population aging level of the core area of the capital,selecting four representative streets as the research scope for onsite investigation.Based on the research on the construction of domestic and international living circles and the evaluation of pedestrian space,the main influencing factors of elderly people’s walking behavior are proposed,and a pedestrian space evaluation system in the core area of the capital is constructed from the perspective of elderly people’s living circles from three aspects:facility accessibility,space,and landscape environment.A total of 32 impact factors were selected,including 19 indicators of convenient reachability of facilities,7 indicators of space safety continuity,and 6 indicators of comfort and humanity of the environment.Invite experts from relevant fields to evaluate and obtain relative weights between indicators.Using big data analysis,field research,data measurement and data visualization,the content and evaluation results of each index of typical street pedestrian space are obtained,and the semantic content is converted into quantitative scores.Based on the evaluation results,the existing problems in the walking space of the core area of the capital city were summarized.Based on this,problem oriented optimization was carried out on the walking space of the elderly from three levels to improve the comfort of the walking space and enhance the adaptability of the walking space to the elderly.To provide reference for the quantitative evaluation of walking space in the living circle of the elderly population,and to explore more targeted and scientific methods for optimizing walking space.
