摘　　要：城市道路横断面的设计是城市道路设计的重中之重。通过东北部调线工程的设计实践,考虑规范对车道数的描述,对国内相关类似城市环线快速路车道数的统计,针对远期外环线全线快速化改造后对既有外环线改造的影响等因素,并根据交通量预测及分析的结果,多方面论证,进行横断面设计。The cross-section design of urban road is the priority among the priorities in the urban road design.According to the design practice of the northeastern line project, it is considered to standardize he description of the lane number and the statistics of the ring expressway lane numbers in the similar cities of China.Aiming at the influence of the expressway reconstruction of the whole long-term outer ring line on the reconstruction of the existing outer ring line, based on the forecast and analysis results of traffic volume, and after the demonstration of many aspects, the cross-section design is carried out.
