农村公路急弯、陡坡、路侧险要等典型路段往往是事故易发多发路段。在现阶段农村公路安保工程资金有限的情况下,需对既有典型路段的事故风险进行定量评价和排序,为隐患路段的排查和安保工程分期实施提供依据。在现有研究成果的基础上,构建典型路段事故风险评价指标体系,提出一种基于贝叶斯网络的农村公路典型路段事故风险评价方法。该方法能有效集结专家知识和经验定量评价典型路段(包括单一路段和组合路段)的事故风险,并可以随着数据的更新不断完善模型。在农村公路事故资料相对缺乏的情况下,该方法具有较强的实用性。
農村公路急彎、陡坡、路側險要等典型路段往往是事故易髮多髮路段。在現階段農村公路安保工程資金有限的情況下,需對既有典型路段的事故風險進行定量評價和排序,為隱患路段的排查和安保工程分期實施提供依據。在現有研究成果的基礎上,構建典型路段事故風險評價指標體繫,提齣一種基于貝葉斯網絡的農村公路典型路段事故風險評價方法。該方法能有效集結專傢知識和經驗定量評價典型路段(包括單一路段和組閤路段)的事故風險,併可以隨著數據的更新不斷完善模型。在農村公路事故資料相對缺乏的情況下,該方法具有較彊的實用性。

Typical sections such as sharp turns, steep slopes and dangerous roadsides of the rural roads tend to be crash prone sections.In the case of limited budget for highway safety enhancement project,in order to identi-fy potential high-risk sections and provide the basis for implement in phases of safety enhancement project, it is necessary to evaluate quantitatively and sort the crash risk of typical sections.On the basis of related resear-ches, a crash risk assessment index system for typical sections has been constructed.And a crash risk assess-ment method for typical sections of rural roads using Bayesian networks was proposed.It is effective to evaluate the crash risk of typical sections ( including single sections and combination sections ) by combining expert knowledge and experience with the proposed method.It was also noted that the proposed model could be con-stantly improved as related data updated.The proposed method showed promise to be used for crash risk assess-ment especially when lack of accident relative information.
