摘　　要：通过对典型的过村镇公路无信号平面交叉口的实际调查和观测,基于交通冲突理论,运用预测模型,对交叉口交通冲突数进行预测,并根据过村镇公路交叉口的特点建立交通冲突比率安全评价模型,并对该类交叉口的交通安全进行全面的评价。根据评价结果及交叉口的安全现状,提出可行的安全改善措施。Based on the actual surveys and observations of typical non-signalized intersection through town and the traffic conflict theory, the number of traffic conflicts at intersection was predicted using prediction model. The traffic conflict rate safety assessment model was established based on the characteristics of the intersections through town, and the traffic safety of these intersections was evaluated. The effective safety improvement measures were put forward according to the assessment results and the safety status of intersection.
