高速公路旁广告牌不同密集程度对驾驶行为的影响

摘要

目的：探讨高速公路旁广告牌不同密集程度对直行路段和转弯路段驾驶行为的影响。方法：选取26名有驾照的被试在驾驶模拟器上进行实验，数据采用SPSS20.0进行统计分析。结果：跟车时看不同密集度的广告牌，无论弯道还是直行，跟车距离、横向偏移差异有统计学意义（P＜0.05），密集度多的广告牌，横向偏移大，跟车距离小；实时速度差异无统计学意义（P＞0.05）。弯道和直行差异有统计学意义（P＜0.05），实时速度为弯道小于直行，跟车距离、横向偏移为弯道大于直行，弯道时影响更大。结论：广告牌的不同密集程度对驾驶行为的作用受路型的影响。%Objective:To investigate whether the density of billboards influences the driving behaviors on the straight and turning lanes of the expressway. Method:Twenty six subjects with driving licenses were selected to conduct the experi-ment on the driving simulator. The data was analyzed by SPSS20.0. Results:With attention to the billboards of different density when following a car, the results showed that whether on is turning lanes or straight lanes, there were significant dif-ferences in car-following distance and lateral deviations (P<0.05), the more billboards, the more lateral deviations, the less car-following distance, but there were no significant difference in driving speed(P>0.05). There were significant differences between turning lanes and straight lanes(P<0.05), compared with straight lanes, the turning lanes were less in driving speed and greater in car-following distance and lateral deviations. Conclusions:Effects of different intensity of the billboards on driving behavior are influenced by the type of the road.
