高速公路互通式立交连续出口和入口间距研究
Study on adjacent exit and entrance distance of freeway interchanges
摘要
Abstract
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.关键词
