摘要
当前路线设计规范采用的设计方法是基于设计车速、"以力学要求为本"的,并不考虑人的心理、生理负荷和承受度,不是"以人为本"的设计方法。综合设计车速理论、"宽容性设计理念"和交通工效学的基本思想,提出修正后的"宽容性设计理念"的基本思想,即以满足车辆动力学需求为设计底线,以交通参与者在交通环境中的心理、生理等方面的"合理需要"为中心和校核指标,综合考虑交通参与者、交通工具、道路设施与交通环境之间的相互协调、耦合,以安全、舒适作为交通系统设计的基本目标。将"宽容性设计理念"的基本思想应用于广西某事故多发路段的改造设计,探讨了基于"宽容性设计理念"的道路设计方法。结果表明,该方法能很好地提高道路运营的安全性。
The method provided in the in-force specifications for highway alignment design is based on the design speed theory, being mechanics-oriented and with no consideration of traffic involvers＇ psychological and physiological bearing capacity. Therefore, it is not people-oriented. Combined with the concept of forgiveness design, traffic ergonomics and design speed theory, a design method for safety improvement of accident-prone highway is presented： satisfaction of vehicle dynamics requirements as the baseline for alignment design, the rational need of traffic involvers psychologically and physiologically as the center consideration and inspection indexes, comprehensive coordination of the interaction of traffic involvers, vehicle, road facility and traffic environment on each other, and safety and comfort as the fundamental goal for traffic system design. The method is applied in the safety improvement design of an accident-prone highway in Guangxi Province as a case study. Investigation of the rehabilitated highway one year after its operation shows that the operation safety of the highway is satisfactorily improved.
