School is one of the important elements in the public service facilities. Its spatial distribution and accessibility will affect the chance and convenience of students to go to school. The accessibility plays an important role in the planning location of schools. On the one hand, we can use it to adjust schools which exist already, on the other hand, we can use it to choose location for new schools. So the article takes the accessibility into account in schools planning. Using MapX and Delphi, the article develops information system, by which the route can be chosen based on the shortest time and the isograms and service converge maps of schools accessibility can be generated. By this way, the time and route of any point in region to go to school can be attained. Based on traffic network, this article evaluates the accessibility of senior high schools in Yizheng City. Some conclusions and suggestions are drawn as follows. The shortest time to go to school is less than 30 min. The most accessible regions are distributed mainly around Zhenzhou Town, Chenji Town and Puxi Town whose accessibilities are less than 10 min. Outward the three towns, the accessibility weakened gradually. The worst accessible regions are distributed in Hexiang Village, Qianke Village and Shuangjian Village of Dayi Town, Lixin Village of Chenji Town, Changshan Village of Qinshan Town, Shuangqiao Village of Puxi Town, Fangqiao Village of Xinji Town, whose accessibilities are between 20 min and 30 min. As for the capacity of senior high schools, the capacities of Nanjing Normal University Affiliated 2nd Senior High School, Jingcheng Senior High School, Chenji Senior High School and Puxi Senior High School have not met present students' demands, but Yizheng Senior High School,Yizheng 2nd Senior High School and Yizheng Industry Senior High School have a surplus capability. At last, the article proposes some planning assumptions, such as combining Yizheng Senior High School and Yizheng 2nd Senior High School, improving the conditions of Chenji Senior High School, increasing investment appropriately to Nanjing Normal University Affiliated 2nd Senior High School, Jingcheng Senior High School and Puxi Senior High School.
