摘　　要：城市道路快速化改造,根据交通需要设计的主辅出入口,当条件受限时经常出现“先入后出”的情况,此时对分、合流区及交织区进行通行能力评价尤为重要。以某市内环线提速改造二期工程中的北线西段为例,介绍一处典型的出入口之间分流区、合流区及交织区通行能力评价过程,并确定服务水平等级,以验证设计方案在交通运行方面的可行性。For the rapid reconstruction of urban roads,the main&auxiliary entrances&exits are designed according to the traffic needs,when the conditions are limited,the situation of first in&then out often occurs.It is particularly important to evaluate the traffic capacity of the diversion,merging&weaving areas.Taking the west section of the north line in the second phase of the speed increase reconstruction project of the inner-ring of a city as an example,it introduces the evaluation process of the traffic capacity of a typical diversion,merging&weaving areas between entrances&exits,and determines the service level to verify the feasibility of the design scheme in traffic operation.
