The growth rate of adults older than 65 in Canada is increasing more rapidly than the population as a whole. This increase is reflective of the aging baby boomer population. That population is known to have a strong attachment to automobiles, which might be reflected in their travel behavior as they move toward different stages in their older life. The purpose of this paper is to contribute to the understanding of the travel behavior, mainly public transit usage, of Canada’s older population relative to younger cohorts. A pseudocohort analysis was conducted in Montreal, Quebec, Canada, of residents who were 50 or older to follow changes in public transit use of similarly aged respondents from 1998 to 2013. The results revealed that older generations used public transit more than younger generations did at the same age. In addition, the most recent survey year showed a stagnation of transit use across all age groups. Differences in transit use between males and females were more pronounced in earlier cohorts, but the difference was decreasing in more recent years. These findings add to the growing body of work suggesting that the nature of transportation behavior in seniors is changing, and accordingly planners and engineers cannot expect the baby boomer generation to behave the same way as previous generations. Addressing the transportation needs of seniors around the world will be an important challenge for planners and engineers, as the population of seniors is growing more rapidly than the population as a whole in the majority of developed countries. This growth imposes new challenges on the transportation system because of differences in the travel behavior of today’s older adults compared with that of previous cohorts of seniors.

Transit agencies often focus on developing strategies aimed at reducing travel time to increase passengers' satisfaction. One strategy used by transit agencies to reduce passenger activity time, and accordingly travel times, is the implementation of all-door boarding -a service allowing transit users to board and alight vehicles through any door. The present study uses data collected in Montreal, Canada, to assess the impacts of an all-door boarding pilot project from two points of view: (1) operationally through passenger activity time, and (2) by assessing passenger satisfaction. Operationally, the results reveal that when compared to a similar bus route that does not allow all-door boarding, the all-door boarding strategy shows a savings of five percent in passenger activity time at regular stops, while time savings at high passenger activity stops such as metro stations experienced time savings of around 19 percent. Thus, savings are maximized at stops with high passenger demand. Additionally, with regard to user perceptions, the results reveal that passengers who use the all-door boarding service are more satisfied with bus service, particularly with on time performance. Overall, the results of this study demonstrate that all-door boarding is an effective strategy to improve the quality of service due to the associated time savings and increased customer satisfaction. Finally, the study offers important recommendations to transit planners and policy makers to effectively implement and maximize the benefits of an all-door boarding policy based on statistical analysis and on-site observations.
