基于驾驶员生理心理变化的村镇公路限速标准研究

Research on Speed Limits Standard on Village Road Base on Driver's Psychological and Physical Reactions

针对目前我国村镇公路交通组成和道路周边环境的复杂性和现有公路限速方法只能根据道路设计标准确定限速值难以考虑周边环境的复杂性的状况,提出了应用驾驶员心生理变化指标确定限速标准的方法。并通过实例说明方法的可行性,从而为周边环境干扰较大的村镇公路限速标准的确定提供了参考。

In order to solve the problem of nonuniform cognition , undefined design standard and confused construction meth- od to the village transit highway , the area around the village transit highway is investigated and the particularity of the traffic characteristics is analyzed. According to the influence on highway capacity from different cross - sections of the similar existing highways, it is thought to adopt vehicle and bicycle separation cross - section standard of urban road due to complex environment around the village transit highway. And by comparison of primary technical specification of two different cross - sec- tions design plan in a representative engineering example, reference basis are provided for cross - section choice in design of the village transit highway.
