随着旅游业的快速发展,旅游城市在法定节假日出现了交通需求的大幅增长,导致不同程度的交通问题。本文利用厦门市的浮动车数据(FCD),分别选取2014年10月1日与10月14日作为节假日与工作日的样本进行研究,首先通过OD点核密度估计判断节假日与工作日出行在时空上的差异,确定研究的时空范围;其次,通过对FCD数据进行核密度估计分析旅游景点周边的车流量变化,并与路段的等级、车道数等道路设施属性进行对比,推测路网的容量;最后进一步通过计算路网中路段行程车速验证方法的可行性。结果显示:节假日期间的旅游交通与工作日的通勤交通在时空分布上存在差异,同时基于FCD数据研究旅游景点周边的路网容量是有效的,厦大—南普陀景点周边路网在节假日期间无法满足车流量的需求。本文对旅游景点周边路网容量的评估结果可为旅游旺季旅游路网的合理规划与管控提供依据。
With the rapid development of the tourism industry, the tourist cities have witnessed a substantial increase in traffic demand on statutory holidays, leading to different levels of traffic problems. In this paper, Xiamen City, using the floating car data (FCD), were selected on October 1 and October 14, 2014 as a holiday and weekday samples were studied first through the OD point nuclear density estimation to determine the holiday and working day trip in time and space Secondly, through the nuclear density estimation of FCD data, the change of traffic flow around the tourist spots is analyzed, and the road network capacity is estimated by comparing with the road facilities’ attributes such as the grade, number of lanes and so on. In the end, the feasibility of the method of vehicle speed verification for road sections in the road network is further analyzed. The results show that there are differences in the spatial and temporal distributions of traffic traffic during the holidays and working days, and it is also effective to study the capacity of the road network around the tourist attractions based on the FCD data. The road network around the Xiamen University-Nanputuo attractions can not be satisfied during the holidays Traffic demand. In this paper, the assessment results of the capacity of the road network around the tourist attractions can provide the basis for the rational planning and management of the tourist road network during the tourist season.
