The main objective of this paper is to highlight travel patterns of older adults living in the United States as depicted in the 2001 National Household Travel Survey (NHTS). The NHTS is a national data collection program sponsored by the Bureau of Transportation Statistics and the Federal Highway Administration. It is the first national comprehensive household survey of both daily and long-distance travel, allowing for analysis of the full continuum of personal travel by Americans. To better understand the transportation needs of older Americans, it is useful to examine how travel patterns differ across age groups. The intent is to present basic travel characteristics of older adults (age 65+) and allow for comparisons with younger adults (ages 19-64). Travel-related characteristics of older adults in the United States: Results of the 2001 survey showed that older Americans travel extensively and rely on personal vehicles as heavily as their younger counterparts. Older Americans conduct 89% of their travel in personal vehicles.
Older adults tend to be less mobile in that they take fewer trips, travel shorter distances, and have shorter travel times. This pattern is even more pronounced among older women. They are also more likely to suffer from self-reported medical conditions that further limit their travel. Characteristics of long-distance travel by older adults: Older men and women take long-distance trips at about the same rates and show a strong preference for using personal vehicles. And, while men and women take an equal percentage of their trips by air, older women show a strong preference for bus travel.
Although older Americans travel extensively, they are less mobile than their younger counterparts. This pattern is more pronounced among older women and among those with self-reported medical conditions that affect their ability to travel outside their home. Older women consistently take the least number of trips per day, have the lowest driving rates, travel the shortest distances, and are more likely to report medical conditions that limit their travel. For men and women who have to give up driving, alternative means of transportation becomes a necessity. Yet, use of alternative transportation is relatively low; excluding personal vehicle and walking, all other means of transportation account for about 2% of daily travel. Further, of those with medical conditions that affect their travel, only about 12% use special transportation services such as dial-a-ride.
本文的主要目的是突出2001年全国居民出行调查(NHTS)所描绘的居住在美国的老年人的出行模式。NHTS是由美国运输统计局和联邦公路管理局发起的一项全国性数据收集项目。它是首次对日常和长途出行进行的全国综合性家庭调查,能够对美国人个人出行的整个连续过程进行分析。为了更好地了解美国老年人的交通需求,研究不同年龄组的出行模式如何不同是很有用的。目的是呈现老年人(65岁及以上)的基本出行特征,并与年轻人(19 - 64岁)进行比较。美国老年人与出行相关的特征:2001年的调查结果显示,美国老年人出行广泛,并且与年轻人一样严重依赖私人车辆。美国老年人89%的出行是乘坐私人车辆。
老年人的行动能力往往较弱,因为他们出行次数较少、出行距离较短且出行时间较短。这种模式在老年女性中更为明显。他们也更有可能患有自我报告的健康问题,这进一步限制了他们的出行。老年人长途出行的特征:老年男性和女性进行长途旅行的比例大致相同,并且强烈倾向于使用私人车辆。而且,虽然男性和女性乘坐飞机出行的比例相同,但老年女性强烈倾向于乘坐公共汽车出行。
尽管美国老年人出行广泛,但他们的行动能力比年轻人弱。这种模式在老年女性以及那些患有自我报告的影响其离家出行能力的健康问题的人群中更为明显。老年女性每天出行次数始终最少,驾车率最低,出行距离最短,并且更有可能报告限制其出行的健康问题。对于不得不放弃驾车的男性和女性来说,替代交通方式成为必需。然而,替代交通方式的使用率相对较低;除了私人车辆和步行外,所有其他交通方式占日常出行的比例约为2%。此外,在那些患有影响其出行的健康问题的人群中,只有约12%使用诸如电话预约乘车等特殊交通服务。
