厦漳泉城市群小时交通圈研究

本文基于2014年厦漳泉城市群交通网络数据和调查数据,采用问卷调查确定城内交通时间及交通时间满意度时间阈值,应用凸壳理论划分城际理论小时交通圈,继而利用城内交通时间修正城际理论小时交通圈,生成城际实际小时交通圈,并结合百度地图划分基于交通时间满意度的城内小时交通圈。研究结果表明：①城际理论小时交通圈均超过本市域范围,而厦门、漳州和泉州各城市城际实际小时交通圈面积相较于城际理论小时交通圈大幅缩小,缩小幅度分别为91.7%、82.9%、83.9%,覆盖区域主要为各自市域范围;②受访者城内交通时间为31~61 min;而使用公交车通常需60 min以上到达汽车站、90 min以上到达动车站,处于不满意甚至很不满意的时间阈值内,其中非常不满意占主导地位;③67.71%的受访者对城际交通时间表示很满意或满意,但69.1%受访者对城内交通时间表示很不满意或不满意。厦漳泉城市群城内交通系统有待改善,建议应完善厦漳泉交通网络尤其是城内交通网络。

Hourly communication area: A case study of Xiamen-Zhangzhou-Quanzhou urban agglomerations,China

Hourly communication area (HCA) study has attracted significant attention in China within the context of urban agglomeration research. Using ArcGIS 10.1, this study analyzes the data on traffic networks as well as from the surveys conducted in Xiamen-Zhangzhou-Quanzhou urban agglomerations (XZQ), Fujian Province, in 2014 to delineate theoretical HCAs by applying the convex hull method, establish the actual HCAs according to the intra-city travel time, delineate the intra-city HCAs based on travel time satisfaction using Baidu map, and explore satisfaction to intercity travel time and intra-city travel time using questionnaire survey results. The analysis shows that: (1) The extent of theoretical HCAs of XZQ is beyond the borders of the cities, with areas of 15473.3 km², 16356.7 km², and 19276.9 km², respectively. Furthermore, this article shows that the travel time to long-distance transport stations in XZQ ranges from 31 to 61 minutes, resulting in a reduction in the actual HCAs of 91.7%, 82.9%, and 83.9%, respectively, compared to the theoretical HCAs. There are only a few areas of intersection between neighboring cities. (2) The respondents in XZQ usually spend more than 60 minutes on the way to the coach stations and more than 90 minutes to the railway stations by bus, and the travel time falls in the Unsatisfactory, even Very unsatisfactory critical time category. The intra-city HCAs of Very satisfactory, Satisfactory, Medium, Unsatisfactory, and Very unsatisfactory categories are 17.91 km² (0.39%), 45.58 km² (1.00%), 112.76 km² (2.47%), 212.20 km² (4.65%), and 4179.46 km² (91.50%), respectively, expand along the main roads in the city and are in quasi-concentric circles. (3) 67.71% of the respondents reported Very satisfactory and Satisfactory intercity travel time, whereas 69.1% of the respondents reported Very unsatisfactory and Unsatisfactory intra-city travel time, which shows that the intra-city transportation of XZQ has not met the demand of the majority of the respondents, and the intra-city urban transportation systems should be improved. We recommend that the government should improve the HCA especially the intra-city HCA in XZQ. Policies should not only focus on the intra-city public transit systems but also build adequate public transit terminals to facilitate passenger transfer, such as new metro or light rail systems.
