The invention discloses a driving risk evaluation method for a small-clear-distance road section of a tunnel and an intercommunication entrance and exit. The method comprises the following steps: firstly, obtaining road parameters of a small-clear-distance road section to be evaluated; then the road parameters are input into a first evaluation model and a second evaluation model respectively to obtain a corresponding first evaluation result and a corresponding second evaluation result, the first evaluation model is an evaluation model with a traffic conflict rate as an index, and the second evaluation model is an evaluation model with a heart rate growth rate as an index; and finally, determining the risk level of the to-be-evaluated small-clear-distance road section in a risk level table according to the first evaluation result and the second evaluation result. The driving risk of the tunnel and the small-clear-distance road section of the intercommunication entrance and exit can be quickly and simply evaluated.
本发明公开了一种隧道与互通出入口小净距路段行车风险评价方法,先通过获取待评价小净距路段的道路参数;然后将所述道路参数分别输入到第一评价模型和第二评价模型中得到对应的第一评价结果和第二评价结果,所述第一评价模型是以交通冲突率为指标的评价模型,所述第二评价模型是以心率增长率为指标的评价模型;最后根据所述第一评价结果和第二评价结果在风险等级表中确定待评价小净距路段的风险等级,实现了快速简捷地评价隧道与互通出入口小净距路段行车风险。
