摘　　要：区域交通可达性的分析对于交通运输网络的布局以及设施、路网结构的优化极为关键。本研究以公路公共客运站点为着眼点,将区域可达性分成城际可达性与城市内部可达性,综合运用空间阻隔法、累积机会法和成本栅格法,结合客运班次量和出行时间,对于城市间的交通可达性进行探究,并以长三角区域为例进行了分析。结果显示:(1)在城际可达性方面,上海与长三角区域其他40个城市的平均城际时间可达性为5.20h。(2)在城市内部可达性方面,上海作为起点城市,仅有20%的地区客运站点时间可达性在1h之内,而上海作为终点城市,则有40%的地区站点时间可达性在1h之内,站点的放射可达性好于吸引可达性。(3)长三角区域城际时间可达性在3h以内的占26%,所有班次的平均行程时间为4.65h。(4)长三角区域内东部沿海地区的城市内部可达性最好,由东往西的城市内部可达性在变差,最大差值为1.05h,变化幅度为94%。The analysis of regional traffic accessibility is critical to the layout of the transportation network and the optimization of the facilities and road network structure. This paper focuses on highway public passenger transport stations, divides regional accessibility into intercity accessibility and intracity accessibility,comprehensively uses space barrier method, cumulative opportunity method and cost grid method, combined with passenger transport frequency and travel time, to explore the traffic accessibility between cities, and analyze the Yangtze River Delta as an example. The results show:(1) In terms of intercity accessibility, the average intercity time accessibility between the central city Shanghai and other cities in the Yangtze River Delta is 5.20 h.(2) In terms of internal accessibility, Shanghai as the starting city, only 20% of the regional passenger station time accessibility is in 1 h, while Shanghai as the destination city, 40% of regional passenger station time accessibility is in 1 h. the radio accessibility of the site is better than the attraction accessibility. It shows that the radiation accessibility of the passenger station is better than the attraction accessibility.(3) 26%of the intercity time accessibility in the Yangtze River Delta region is within 3 h, and the average travel time of all shifts is 4.65 hs.(4) The internal accessibility of cities in the eastern part of the Yangtze River Delta is the best, while the internal accessibility of cities from east to west is getting worse. The maximum difference is 1.05 h, with a change of 94%..
