| Under the background that China has entered the rapid development stage of social aging,more and more attention has been paid to how to carry out transportation planning to satisfy the happiness of the elderly in their later years.For the elderly,on the one hand,their physical function declines with aging,and their ability to travel begins to decline,and their willingness to travel is often difficult to be met.On the other hand,in the face of the increasingly large elderly population,the mismatch between the existing transportation service system and the travel of the elderly population makes the mobility problems and contradictions of the elderly arise.Accessibility,as a basic problem of transportation,is also a basic condition of individual life.The personal accessibility of the elderly directly affects their sense of well-being in later life.For elderly individuals,accessibility reflects how easy it is for elderly people to meet their needs for daily outdoor activities.From the perspective of activities,the personal accessibility of the elderly is the result of the joint influence of the travel ability and public transport accessibility of the elderly.Through research and analysis,it is found that leisure activities of the elderly are the best expression of the correlation between activity travel of the elderly and personal accessibility,and physical energy consumption parameter is used to represent the activity and travel preference of the elderly,and a hierarchical regression model of personal accessibility of the elderly is established.The main research contents and achievements of this paper are as follows:1.The principal component analysis method was used to extract the factors.The results showed that the elderly’s outdoor leisure activity travel behavior was influenced by both internal and external factors.The outdoor shopping activity and the outdoor medical treatment activity of the elderly are significantly affected by the external factors of the elderly.2.Based on the influencing factor model of the outdoor leisure activities of the urban elderly,the factor scores and activity preferences of the elderly in the travel activities were analyzed and classified.For leisure activities,the elderly were divided into three categories.The second category of the elderly to participate in outdoor leisure activities can only choose to exercise;Third,the elderly participate in outdoor leisure activities convenient transportation;For shopping activities,there are market shopping and supermarket shopping;There are three types of medical activities for the elderly according to whether the hospital is convenient to prescribe medicine.3.In the elderly outdoor leisure travel,travel,strong ability of old people tend to have good individual accessibility,can go to the good leisure environment facilities,travel preferences,preferences and the activity of this kind of old people using public transport mode,and to participate in a variety of leisure activities to meet the elderly leisure motivation;The elderly with poor travel ability have poor personal accessibility and can only travel on foot.They cannot go to municipal parks or regional parks with beautiful environment and perfect facilities.Most of the activities they participate in are walking and fitness activities of a single type,which cannot meet the leisure needs of the elderly. |
