Abstract

In recent decades traffic calming, especially in villages situated on through roads, has become an urgent issue. Various schemes are applied in the transition zones to reduce the inbound traffic speeds and thus improve the traffic safety. The studies conducted in several countries point to different determinants of the speed reduction obtained in this way. This article deals with the schemes including a central island horizontally deflecting one lane, located in transition zones to villages with 70 km/h speed restriction on two-lane roads (6 m carriageway width). In order to identify the speed reduction determinants, the speeds before and after chicanes were measured and the effect of the three criteria was investigated, characterising: the traffic management scheme, road design parameters, landscape elements present in the surroundings of the transition zone and visibility conditions. Based on the confirmation of logical tautology of many pre-selected factors, one aggregate parameter was proposed for the assessment of the practicable level of speed reduction, combining the effect of the selected factors in the above-mentioned criteria. Statistical analysis of the obtained results confirmed a statistically significant relationship between both the speed reduction value and the speed reduction index, and the aggregate parameter proposed by the authors. Factors related to the surrounding landscape and visibility conditions were found to have the greatest direct effect on speed reduction. The chicanes chosen in the final step of the proposed design process should be enhanced by additional solar-powered elements ensuring their improved visibility. These devices should not, however, require any additional energy supply and should not increase the construction or maintenance costs.
70公里/小时限速的乡村过渡区公路减速道有效性的决定因素鉴定
近几十年来,交通平静已成为一个紧迫的问题,特别是在位于公路上的村庄。在过渡区采用各种方案,以降低入站交通速度,从而提高交通安全。在几个国家进行的研究指出了以这种方式获得的速度降低的不同决定因素。本文涉及的方案包括一个中央岛水平偏转一条车道,位于村庄的过渡区,在双车道道路(6米行车道宽度)上限速70公里/小时。为了确定减速的决定因素,测量了弯道前后的速度,并研究了三个标准的影响,分别是交通管理方案、道路设计参数、过渡区周围的景观元素和能见度条件。在确认多个预选因素逻辑同义性的基础上,结合上述标准中所选因素的影响,提出了一个评价实际减速水平的综合参数。对所得结果的统计分析证实了减速值、减速指数与作者提出的聚合参数之间存在显著的统计学关系。与周围景观和能见度条件有关的因素对速度降低的直接影响最大。在建议设计过程的最后一步中选择的弯道应该通过额外的太阳能元件来增强,以确保其更好的可视性。然而,这些装置不应要求任何额外的能源供应,也不应增加建造或维护费用。
