摘　　要：在公路互通式立交匝道路线设计中,计算立交匝道平面线位曲率是至关重要的一环。通过精确计算,可以确定匝道的线形设计,以满足不同交通流量的需求。此外,为了提高匝道的行车安全性,还需要设置附加路拱,为驾驶员提供足够的视距和行车空间。这些优化设计有助于提升整个立交系统的通行效率和安全性。根据测试结果,设计的公路互通式立交匝道路线在不同时间段内,小汽车和卡车的平均速度和平均延误均在可接受范围内,且整体通畅性评分均较高,说明该公路互通式立交匝道路线设计方法具有一定的优势。In the design of highway interchange ramp route,the calculation of the plane curvature of interchange ramp is a crucial part.Through accurate calculation,the linear design of the ramp can be determined to meet the needs of different traffic flows.In addition,in order to improve the driving safety of the ramp,additional road arches need to be set up to provide sufficient visual distance and driving space for the driver.These optimized designs help improve the traffic efficiency and safety of the entire interchange system.According to the test results,the average speed and average delay of cars and trucks are within the acceptable range in different time periods,and the overall patency scores are high,indicating that the highway interchange ramp route design method has certain advantages.
