Abstract: As the representative power of the central region，Wuhan city circle has established its economic position in the whole country with its unique traffic location advantage.From the road traffic accessibility and potential，the traffic location level of each city in Wuhan city circle was studied.The distance measurement method was used to measure the urban traffic accessibility，and the potential model was introduced to evaluate the city’s location potential.On this basis，the comprehensive traffic location level of each city in Wuhan city circle was obtained by weighting.The results show that：① the comprehensive traffic location of Wuhan， Ezhou and Xiantao is relatively high，and the location advantage is stronger; ② Huanggang，Huangshi and Tianmen are followed closely ，and the advantages of traffic location are relatively weak; ③ the traffic location in Xiaogan，Xianning and Qianjiang is lower than that of the above cities.

Key words: traffic and transportation engineering, Wuhan city circle, location, transportation accessibility, potential

摘要： 武汉城市圈作为中部地区的代表力量，以其特有的交通区位优势奠定了在全国的经济地位。从道路交通通达性、潜能来研究武汉城市圈内各城市的 交通区位水平，采用距离度量法测算城市交通通达性，引入潜能模式来评估城市的位势，在此基础上通过加权得到武汉城市圈内各城市的综合交通区位水 平。分析结果表明：① 武汉市、鄂州市、仙桃市的综合交通区位排名较前，区位优势较强；② 黄冈市、黄石市与天门市紧随其后，交通区位优势相对减 弱；③ 孝感市、咸宁市以及潜江市的交通区位相对以上几个城市较低。
