出租车作为城市综合交通系统的重要组成部分,为市民提供了便利的交通服务。现阶段,对比网约出租车的迅速发展,巡游出租车在定价、服务等方面所存在的一些问题逐渐显现出来。文章通过问卷调查西安市市民分别对巡游出租车和网约出租车的满意度,将结果进行对比分析,利用 R 语言软件对西安市的巡游出租车工作日订单数据进行出行特征分析,得出西安市巡游出租车运行的时间、空间特征。针对需要改进的问题,做出巡游出租车运营服务升级的优化策略,从而提高巡游出租车在出租车市场上的竞争力。 相似文献

为了提高民众对新能源汽车接受度,结合技术接受模型和感知风险理论,考虑新能源汽车特性和地区特征,构建了消费者新能源汽车购买意愿的结构方程模型。利用 SPSS 和AMOS 对收集的数据进行统计和拟合处理,深入分析并总结民众新能源汽车购买意愿的影响因素。研究结果表明,感知风险、感知成本对购车意愿有显著影响,同时民众的新能源汽车知识基础对其感知风险和感知成本有显著负向影响。最后基于以上结论提出相应的政策和策略建议,以期为地区推广新能源汽车提供理论基础。 相似文献

Automated driving systems are increasingly widespread in the automotive industry. To operate automobiles that are assisted by such systems, drivers must correctly understand their functionality and limitations. Hence, focusing on the rapidly spreading technology of automated braking, this study seeks to clarify the general public's understanding of automatic braking systems. A total of 210 Japanese people responded to a questionnaire regarding how automatic brakes are operated, how they work, when they disengage, and so on. The proportion of those who misunderstood the operation of the system is not especially high, but there were a certain percentage of people who had misconceptions; e.g., some believed that automatic braking could detect pedestrians or bicycles. Moreover, respondents were under the impression that drivers cannot readily disengage automatic braking systems. If they mistakenly use the automatic brake, there is a possibility of posing a risk to the road transportation system. 相似文献

This study analyzes pedestrian receptivity toward fully autonomous vehicles (FAVs) by developing and validating a pedestrian receptivity questionnaire for FAVs (PRQF). The questionnaire included sixteen survey items based on attitude, social norms, trust, compatibility, and system effectiveness. 482 Participants from the United States (273 males and 209 females, age range: 18–71 years) responded to an online survey. A principal component analysis determined three subscales describing pedestrians’ receptivity toward FAVs: safety, interaction, and compatibility. This factor structure was verified by a confirmatory factor analysis and reliability of each subscale was confirmed (0.7 < Cronbach’s alpha < 0.9). Regression analyses investigated associations with scenario-based responses to the three PRQF subscale scores. Pedestrians’ intention to cross the road in front of FAVs was significantly predicted by both safety and interaction scores, but not by the compatibility score. Accepting FAVs in the existing traffic system was predicted by all three subscale scores. Demographic influence on the receptivity revealed that males and younger respondents were more receptive toward FAVs. Similarly, those from urban areas and people with higher personal innovativeness showed higher receptivity. Finally, a significant effect of pedestrian behavior (as measured by the pedestrian behavior questionnaire) on receptivity is explored. People who show positive behavior believed that the addition of FAVs will improve overall traffic safety. Those who show higher violation, lapse and aggression scores, were found to feel more confident about crossing the road in front of a FAV. This questionnaire can be a potential research tool for designing and improving FAVs for road-users outside the vehicles. 相似文献

随着汽车保有量的迅速增加,交通事故频发,引起事故的主要原因和驾驶员的驾驶行为相关,对于驾驶员来讲,其驾驶行为可表现为驾驶风格。文章借助问卷调查的方式对乘用车驾驶员驾驶风格的影响因素,以及驾驶风格与交通违规、事故的关系予以分析。数据分析结果表明,发现驾驶风格受性别、年龄、驾龄和受教育程度等因素的影响;驾驶员出现交通违规、事故与冒险、愤怒、分心、焦虑驾驶风格之间存在较高的关联性,安全驾驶风格的驾驶员出现事故的几率相对较小。通过驾驶员驾驶风格的测量,有利于对驾驶员胜任力做出评价,采取适当的干预手段从驾驶员层面减少交通事故的发生。 相似文献
