摘　　要：探讨主线和匝道连续分合流时相邻匝道的间距问题,根据每种分合流驾驶行为具体分析,分为主线连续分流及合流、匝道连续分流及合流4种情况,使用车辆变道模型、驾驶员标志识别规律、驾驶规律等方法进行研究。计算可得现行规范对主线侧连续分流匝道间距值规定较小,不推荐使用主线侧连续分流,而匝道连续分合流计算值比现行规范小,可在用地条件或其他条件限制下采用本文计算值。With the increase of traffic need and road network, the distances between interchanges are shorter and shorter, which makes a large effect on traffic efficiency, safety and stability. The values of standards cannot meet the need of real flexible exits combination. This paper concentrates on the issue of the net distance between two adjacent exits on main lines and ramp. Based on specific analysis of different driving behavior, including main line adjacent merge and diverge, ramp adjacent merge and diverge. A series of recommend values for different situations was worked out by modeling with driving behavior, changing lanes and traffic sign recognition rule. The results show ： the value of net distance between two adjacent exits on main lanes is larger than standard which in-dicates this design is not recommended in real. While the calculation value of ramps is shorter than the standard that can be used in real with demonstration.
