With an ever increasing population of older adults (65+ years) in the USA, a better understanding of this population's travel patterns is needed to improve travel mobility and transportation safety.
In this study, we described the travel patterns of older adults in the USA during 2015.
Travel patterns of older adults (65-74 and 75+ years) were compared with younger adults (25-64 years) by frequency and proportion of daily trips. The daily trips of various age groups were estimated using the 2015 American Time Use Survey.
The percentage of daily travellers was 88% for adults (25-64 years), 75% for adults (65-74 years) and 68% for adults (75+ years). While the percentage of privately owned vehicle (POV) drivers and average time of driving POVs decreased, the percentage of POV passengers increased as adults aged. Females were less likely to drive POVs and had decreased average daily driving time, but they were more likely to ride in POVs as passengers and had longer average daily riding times than their male counterparts across all age groups. Older adults were more likely to travel in the mornings and early afternoons (from 8:00 to 15:59) while younger adults were more likely to travel in the late afternoons and early evenings (from 16:00 to 19:59).
POV use is the predominant mode of transit in the USA. As adults age, the percentages of daily travellers and POV drivers decrease. This pattern is more apparent among females than males. This study delineated travel patterns of older adults using a 2015 national survey, and the findings facilitate traffic systems designers and policy-makers to develop and implement initiatives to accommodate older adults' mobility needs and improve traffic safety.
在美国，65岁及以上的老年人数量不断增加，为了改善出行便利性和交通安全，需要更好地了解这一人群的出行模式。
在本研究中，我们描述了2015年美国老年人的出行模式。
通过每日出行的频率和比例，将老年人（65 - 74岁和75岁及以上）的出行模式与年轻人（25 - 64岁）进行比较。使用2015年美国时间使用调查来估计各年龄组的每日出行情况。
成年人（25 - 64岁）每日出行者的比例为88%，成年人（65 - 74岁）为75%，成年人（75岁及以上）为68%。随着成年人年龄增长，私家车司机的比例和驾驶私家车的平均时间下降，而私家车乘客的比例增加。在所有年龄组中，女性驾驶私家车的可能性较小，平均每日驾驶时间减少，但她们作为乘客乘坐私家车的可能性更大，平均每日乘车时间比男性更长。老年人更倾向于在上午和下午早些时候（8:00至15:59）出行，而年轻人更倾向于在下午晚些时候和傍晚早些时候（16:00至19:59）出行。
在美国，私家车是主要的出行方式。随着成年人年龄增长，每日出行者和私家车司机的比例下降。这种模式在女性中比男性中更为明显。本研究使用2015年全国调查描绘了老年人的出行模式，研究结果有助于交通系统设计师和政策制定者制定和实施举措，以满足老年人的出行需求并提高交通安全。
