| 摘要: |
| 为解决城市快速路小间距路段出口预告标志缺失等问题,针对小间距路段出口设置了5种预告标志方案,开展驾驶模拟试验,提取了9种指标进行重复测量方差分析,最终获取了6种显著影响指标. 采用基于熵权法的TOPSIS方法,评估5种方案的设置效用. 结果表明:在快速路小间距路段出口减速车道起点前1.0、0.5 km及起点处设置3次预告标志时,综合设置效果最好；其次为按照中国规范（GB 5768.2—2009）设置4次预告,及按照日本规范设置4次预告. 采用K-means聚类及LSD对比分析,发现1次预告方案指路效果明显较差. 最终建议小间距路段出口前设置3次预告标志,条件受限时应至少进行2次预告. |

| Abstract: |
| To solve the problems such as lack of advance guide signs of small spacing segment exits on urban expressway, this study proposed five kinds of advance sign setting schemes and conducted a driving simulation experiment. Nine types of evaluation indicators were extracted and analyzed by repeated ANOVA, and six indicators were selected which were significantly affected by different schemes. TOPSIS method combined with entropy weight coefficient was used to evaluate the effectiveness of the five schemes. Results showed that it had the best effect on the driving behavior when setting advance guide signs at 1 km, 0.5 km, and 0 km before the starting point of the deceleration lane. It was followed by the scheme with four advance guide signs according to China standard (GB 5768.2—2009), and the scheme with four advance guide signs according to Japan related standards. K-means cluster and LSD comparison analysis revealed that the effectiveness of setting one advance guide sign was poor. Since the scheme of three advance guide signs had the best effectiveness, it is recommended to be adopted. When road conditions are limited, at least two advance guide signs should be set. |
