摘　　要：道路线形的安全评价是从设计阶段保证行车安全的关键，道路平曲线的弯曲程度直接影响着行车安全，单位交角曲线长L／I（曲线长／曲线交角）代表了道路平曲线的弯曲程度。通过大量的行车实验及驾驶员的心率、最高血压的变动与单位交角曲线长L／I的相关分析，结果表明单位交角曲线长L／I可作为道路平曲线设计要素的安全性评价指标。在线形复杂的山区公路，基于人机工程学与工程费用的考虑，行车安全需要的L／I取值应在0．5～1．0之间。The safety evaluation of road alignment is the key to ensure the driving safety, the bending degree of road horizontal curve affects the driving safety directly, the curve length of unit intersection angle-L/I （curve length/intersection angle） denotes the bending degree of the road horizontal curve. Many driving experiments are carried out, the relativity between heart rate,blood pressure changes of drivers and the curve length of unit intersection angle-L/I, are analyzed. The result proves that the curve length of unit intersection angle-L/I can be taken as the safety evaluation index of horizontal curves＇design factors. Based on ergonomics and project cost, the necessary safe value of L/I in mountainous highways with complicated alignment ought to between 0.5 and 1.0.
