Abstract:

Many developed and developing countries are experiencing a sharp increase in the aging population. As age increases mobility decreases. Hence, these people are very vulnerable and they are forced to be socially excluded if proper transportation facility is not provided for them to access services. The Transportation planners and policy makers are responsible to increase the mobility needs of the ageing population. This paper focuses on the mode choice and trip length of senior citizen to access various services. The target group is the senior citizens whose age is 60 years and above. The study area is Tiruchirapalli City Corporation, Tamilnadu, India. The primary data collection was done by household questionnaire survey. The statistical analysis fixed that the travel pattern of a new generation of elderly has less heterogeneity. To further quantify the results Chi – square Automatic Interaction Detection (CHAID) method was applied to investigate the heterogeneity in trip length among the senior citizen. Mode choice for the corresponding trip length was also analyzed. The variables taken for the study are gender, occupation, income, activities, frequency of travel, house hold size, mode and time of travel. The target group is categorized into three, based on their mobility. The results indicate that new generation elderly travel more frequently and longer distance than other groups. Active transport (walking and cycling) is most preferred for shorter distance and Two-Wheeler for longer distance. Female make more leisure trips than male. Older old people (>75) make less trips and their trip length is less than 1Km for walking and as trip length increase they prefer to travel in public transport.
