Examining relationships among perceived benefit,tourist experience and satisfaction: the context of intelligent sharing bicycle

Intelligent sharing bicycle has been a new fashion in China and appeals to more and more tourists. To better understand the experience of tourists traveling on sharing bicycle, this study explored the influence of perceived benefit of sharing bicycle on different perceived experiences, including escape, entertainment, esthetic and educational experiences. The relationships between these experiences and perceived satisfaction were also tested. An effective questionnaire survey was conducted for 296 tourists in Chengdu, China. The results of the study show that perceived benefit significantly relates to all the four dimensions of experience. However, only entertainment and esthetic experience seem to affect tourist satisfaction in this context. The relationship among educational experience, escape experience and tourist satisfaction are insignificant. Theoretical and practical implications of the study results are discussed for further research.

Road accidents involving bicycles: configurations and injuries

This study analyzed the most common types of accident involving bicycles and compared the frequency of injuries. The data source was the database of German In-Depth Accident Study (GIDAS). Cases consist of bicycles and their riders involved in accidents between 2000 and 2010. In most collisions, the bicycle impacted with a car. The percentage of injured bicyclists was higher in collisions with a heavy vehicle and decreased when the bicycle impacted with lighter vehicles. A high percentage of injured bicyclists in single accidents was observed; the most severe injury was more frequently to head and extremities. Accidents involving a car and a bicycle with the right of way in a bicycle path represented about 20% of involved and injured bicyclists. The ten most frequent configurations represented about 60% of involved and injured bicyclists. These results contribute to understand the dangerous scenarios for bicyclists and to suggest preventive actions.     

Prevalence and predictors of bicycle helmet use in a southeastern,US city

Fatalities and head injuries from bicycle-related crashes remain a concern in the United States. Despite legislation in many states, helmet use remains low. This observational study examined the helmet use and related factors in a North Carolina city. The sample consisted of 2088 observations of bicyclists. The objectives were to (1) determine helmet use; (2) describe other safe bicycling practices; and (3) examine the relationship of demographic variables and safe riding practices with helmet use. Helmet use was observed for 25% of the sample. Demographic factors related to helmet use were being female (OR = 1.32), 26 years old or older (OR = 4.94), and White (OR = 2.17). Bicyclists riding on the road with traffic were more likely to wear a helmet than bicyclists riding on the sidewalk (OR = 2.04). Findings indicate that helmet use remains low in the city. Research to monitor, better understand, and promote helmet use is needed.     

从环保角度看电动车新国标

2012年9月1日起,《机动车运行安全托术条件》开始实施,时速在20公里以上、50公里以下,重量超过40公斤的电动车,将被作为轻便摩托车纳入机动车管理范畴。这一新国标的实施将会对人们的日常生活产生重大影响,也将改变很多人骑电动车出行这一环保行为。本文分析并论证了新国标将导致电动自行车使用减少,高耗能摩托车、汽车使用增加,最终导致大气污染加剧、人们生活水平降低。
