Abstract: With the city basic building development and the instant increasing of motor vehicles，there are higher request for building parks，SO the control indexes for park constructing were constictuted according to each city own characteristic．The authors did more particular research for the issues of the park control indexes，brought forward the new concepts of dynamic headroom and put forward the calculation method of the headroom an d suggested a control value for curve width，in order to improve the safe of driving in the park．

Key words: park, control indexes, dynamic headroom, curve widen, drive safe

摘要： 随着城市基本建设和机动车数量的不断增长，对于停车库建设的要求越来越高，各城市根据自身的特点制定 了停车库的配建和控制指标．对停车库的净空和弯道加宽控制指标存在的问题进行了进一步的细化研究，提出了动 态净空的新概念，并得出了动态净空计算方法和弯道宽度的控制指标建议值，提高停车库的行车安全．
