为了这项研究,宾夕法尼亚州立大学的研究人员请求该校的教师、员工和学生完成一系列广泛的在线调查问卷,内容包括健身、健康、交通和停车习惯;骑车或步行的舒适程度和能力;住处与他们在校园内主要工作地点的距离;以及他们认为骑车或步行到那里所需的时间。505名受访者中只有少数人步行或骑车;其中大多数是学生。然后,研究者将受访者估计的通勤时间与谷歌地图计算出的相应路线用时进行了比较。研究人员还以步行或骑车的方式对其中一些路线进行了独立计时。
The survey participants — faculty and staff members above all — proved to be generally poor at guessing active-commuting times. About 90 percent of their estimates were too long by at least 10 minutes. The few assessments close to Google’s were almost always made by riders or walkers. Parking availability and distances affected the estimates. Those with parking permits, a fiercely sought-after campus amenity, tended to overestimate active-commuting times significantly; the closer someone lived to the workplace, the better the guesses. Confidence had an outsize effect, too. The people surveyed, especially women, who had little bicycling experience or who did not feel physically fit thought that active commuting would require considerably more time than the Google calculations.
受访者,尤其是教职员工,在估算活跃通勤用时方面大都很糟。他们估计的时间约有90%都至少超过10分钟。也有少数人给出了与谷歌用时接近的估计,他们几乎都是骑车者或步行者。停车权和距离对估计有所影响。有停车证的人往往会大大高估活跃通勤的用时——停车证是一项很吃香的校园福利。住得离工作地点越近的人猜得越准。信心也会产生巨大影响。没有骑车经验或觉得身体不适的受访者,尤其是女性,对活跃通勤的用时的估计大大高于谷歌的计算。
