Analysis on Comprehensive Transportation Accessibility of Scenic Spots in Metropolitan Area Based on Spatial Simulation:A Case Study of Changsha-Zhuzhou-Xiangtan Metropolitan Area
Comprehensive transportation accessibility has an important impact on the service quality and tourist experience of scenic spots in contemporary metropolitan areas.Previous studies paid more attention to the accessibility of single-mode transportation,and gave less consideration to the accessibility of comprehensive transportation covering highways,railways,high-speed railways and other modes of transportation,along with a lack of the calculation of time that tourists take in both transfer and the last phase of transportation getting to their destinations.All these have led to errors in analysis results,making it difficult to accurately quantify transportation accessibility in metropolitan areas and other areas with complex traffic conditions.In this context,this study aims to build a research framework for the comprehensive transportation accessibility of scenic spots in the metropolitan area through an overall consideration of the traffic share rate,transportation service coverage,travel distance,real-time road conditions,and transfer,parking and walking times,and a whole-process analysis of the first,middle and final sections of tourism transportation.Taking the Changsha-Zhuzhou-Xiangtan metropolitan area as a case,this study used tools such as Amap's JavaScript Application Programming Interface(JSAPI)to collect traffic status data on urban and rural roads,expressways,railway transits,and other related traffic data for 80 scenic spots above 3A level within the metropolitan.It developed a spatial database of scenic spots and their comprehensive transportation and a rose diagram of starting nodes,calculated the traffic share ratio and connection time,and conducted an accessibility analysis of various transportation modes,a spatial analysis of comprehensive transportation accessibility,and a structural analysis of comprehensive transportation accessibility in various scenic spots.Through these spatial simulation methods,the spatial distribution characteristics,rules,and existing problems of comprehensive transportation accessibility of scenic spots in the metropolitan area were thoroughly summarized.The results show that:Firstly,in terms of spatial distribution,the comprehensive transportation accessibility in scenic spots of the Changsha-Zhuzhou-Xiangtan metropolitan area presents a"low-high-low"trend from the urban center to the peripheral areas.Secondly,the role of rail transit is not fully utilized,with tourists heavily relying on highways when accessing scenic spots.Thirdly,problems exist in the organization of various types of transportation,where mutual interference outweighs mutual promotion.Fourthly,the last phase of transportation to access scenic spots also has problems such as the unreasonable design of the main entrance,poor transportation connection with surrounding trunk roads,and insufficient parking capacity.Based on these problems,three optimization measures for the macro transportation planning,the middle traffic organization,and the micro traffic design are proposed.This study offers a new approach and a methodological reference for the spatial quantification and structural study of comprehensive transportation accessibility in scenic spots of metropolitan areas and provides inspiration for further optimizing the tourism transportation system in metropolitan areas and cities amid the integrated development of transportation and tourism industries.
