城市快速路出口编号设置方法及效果评价——以无锡为例

为保障驾驶人能快速确定出口位置,城市快速路出口编号逐渐被很多城市所应用。由于国家标准未对此进行相关规定,导致我国很多城市的出口编号标志存在不惟一、样式不统一等的问题。在调研的基础上,提出了采用数字与文字相结合的编号方法能够准确反映道路特征、流向特征,并确保了出口编号的的惟一性,以无锡快速内环西快速路的出口编号标志设置为例进行了详细解析。最后通过比较设置出口编号标志前后,被测试驾驶人对快速路出口位置的识别时间的改变情况,发现50%测试者的视认性都得到了一定程度改善,验证了快速路出口编号方法的可行性和有效性。 

Urban Expressway Exit Numbering Setting Method and Effect Evaluation:a Case Study of Wuxi City

To ensure the driver to quickly determine export position ,urban expressway exit numbering is gradually used in many cities .However ,many problems still exist including non-uniqueness and disunity in exit numbering and its style in that there is no standard rule at state level .This paper ,on the basis of investigation and research ,proposes an exit numbering setting method that can reflect the features of road ,the flow characteristics to ensure the uniqueness of the exit numbers by illustrating the example of Wuxi Inner-ring West Expressway .Finally ,through contrast test ,the change of driver recognition time between before and after setting exit numbering is compared .It is found out that the legibility of 50% of the examinees is promoted in some degree ,which proves the feasibility and effectiveness of the method .
