Study On Evaluation And Countermeasures Of Urban Tourism Traffic Based On Large Data Around Xiamen University

With the rapid development of tourism,there has been a substantial increase in traffic demand of the tourism cities in the statutory holidays,resulting in varying degrees of traffic problems.With the the rapid development of the new generation of information technology,large data has now become a hot topic.In this context,large data in urban research or urban planning is becoming more and more concerned by geography scholars,urban planners,government managers.Based on FCD data,GIS data and Baidu thermal chart,this paper analyzes and evaluates the tourism traffic,analyzes the factors that affect the tourism traffic,puts forward the countermeasures to improve the service level of the urban network of the tourist city,and makes reasonable planning and takes control measures for the tourist network in the tourist season Provide evidence.In this paper,we first use the FCD data of Xiamen City,select the samples of holidays and working days on October 1 and October 14 respectively.We judge the differences in the time and space between holidays and work days by OD density estimation.And then determine the scope of the study.Secondly,through the nuclear density estimation of the FCD data,analyzing the traffic flow around tourist attractions,compared with the grade of road sections,the number of roads and other facilities,and deduced the capacity of the road network.Finally,the feasibility of the method is verified through the calculation of the road travel speed.Through the evaluation of the capacity of the tourism network,it can provide the basis for the reasonable planning and control measures of the tourism traffic networkSecondly,taking the research in Xiamen University-Southern Putuo attractions as an example,firstly we Study on the temporal and spatial distribution characteristics of tourist activities by using Baidu thermodynamic diagram.Secondly,analyze the factors that influence tourism activities from four aspects such as slow facilities(pedestrian,bicycle lanes),public facilities(bus station),tour routes and attractions management,With the rapid growth of Traffic volume and flow of the Peripheral motor vehicle causing by the tourism activities,it makes the traffic conflict intensified,traffic condition deteriorated sharply,slow walking environment worsening,therefore it is urgent to Improve the slow walk environment,and Encourage the traffic patterns of that the slow walking as the auxiliary and the public transport as the main.Based on the superposition of the truck's nuclear density grid diagram and the Baidu thermal map,the overlapping points of the traffic flow density are analyzed,and theshortcomings of the traffic facilities are obtained,so as to carry out the improvement countermeasures.
