The COVID-19 pandemic has caused incredible impacts on people’s travel behavior. Recent studies suggest that while the demand for public transport has decreased due to passengers’ inability to maintain physical distance inside this mode, the demand for private automobile and active transport modes (walking and cycling) has increased during the pandemic. Policymakers should take this opportunity given by the pandemic and encourage people to use active transport more in the new normal situation to achieve sustainable transportation outcomes. This study explores the expected change in active transport mode usage in the new normal situation in Bangladesh based on the data from a questionnaire survey. The study finds that 56% and 45% of the respondents were expected to increase travel by walking and cycling, respectively, during the new normal situation. On the other hand, 19% of the respondents were expected to do the opposite. The study further identifies the factors influencing the expected change in travel by active transport modes during the new normal situation by developing multinomial logistic regression models. Finally, this study proposes policies to increase active transport use beyond the pandemic and ensure sustainable mobility for city dwellers and their well-being.

The impacts of COVID-19 on the transportation system have received attention from researchers all over the world. Initial findings reveal that patronage of public transport has gone down, while the use of active transport has increased in general. To the best of our knowledge, no study has focused on the pandemic’s effects on motorcycle mode, let alone in the context of an Asian city. We attempted to fill this void in literature by investigating if COVID-19 has influenced people to purchase motorcycles and determining the factors driving their intentions. The study is based on an online survey of 368 people in Dhaka, the capital of Bangladesh. The study found that around 46% of the respondents were expected to increase travel by motorcycle during the post-lockdown period. About 21% of the respondents were also expected to do the opposite. Around 31% of the respondents planned to purchase a motorcycle by August 2021, and the results indicated that the pandemic has influenced more people to purchase motorcycles compared to the pre-pandemic period. The study further identified factors that influenced the respondents’ plan for purchasing a motorcycle during the post-lockdown period applying the binary logistic regression. Based on the findings of the study, policy measures were proposed for controlling the growth of motorcycle numbers and increasing the use of active transport modes as its alternative, and consequently, helping to achieve sustainable transportation outcomes.

This paper explores the impact of smartphone apps on discretionary travel by utilizing a survey of smartphone users in the Canadian city of Halifax, Nova Scotia. Both subjective and objective measures of discretionary trips are analyzed. A number of attributes such as smartphone use for different purposes, individuals’ perceptions and attitudes towards smartphone use and travel, and built environment measures are examined along with socio-demographic characteristics. Overall, results suggest that greater use of smartphone apps increases the number of discretionary trips. Perceptions and attitudes toward app use and travel also affect the number of discretionary trips. The results suggest that those who agreed that smartphone use has improved their daily life are more likely to make fewer social, shopping, and entertainment-related trips. The impact of socio-demographic and built environment attributes is low compared to the other variables considered in the analysis.

This study aims to synthesize knowledge on the travel behavior of millennials and older adults based on literature from 2010 to 2018. The study looks into the different factors that contributed to shaping each generation’s travel behavior. Both qualitative and quantitative studies that fall within the selection criteria are reviewed, with a total of seventy-eight studies selected for review. Thirty-four papers focused on young adults/millennials, 35 included an older adult population, and 9 investigated both younger and older age groups. Six of the studies utilized qualitative methods, 68 applied quantitative methods, and 4 used mixed methods to explore the factors associated with travel behavior. Travel behaviors are explored in terms of mode choice, trip distance, trip frequency, use of alternative transport, ridesharing, and mobility tool ownership. Associated factors are categorized into five themes: personal attributes, geography and built environment, living arrangements and family life, technology adoption, and perceptions and attitudes towards travel options and environment. This study concludes that difference exists between generations in terms of travel behavior, and that the factors that influence each generation’s travel characteristics are either different, or differ in their nature of influence (increase/decrease). Finally, based on the reviewed literature, this study proposes future research directions.

This paper aims to investigate the perceptions of neighborhood conditions and their effect on urban active transportation (UAT) in the context of a city in the Global South. We analyze data from a survey of commuters in the city of Rajshahi, Bangladesh. Concretely, we are interested in cycling and walking. A probabilistic model of mode use is estimated using disaggregate data collected in Rajshahi through a face-to-face survey in 2017. The study reveals that similar to other regions in the world, students are more likely to use active transportation compared to other socio-demographic groups, and that motorized vehicle ownership is associated with lower probabilities of active transportation. Furthermore, the probabilities of choosing active modes at different neighborhood-level conditions were calculated based on the derived model for both students and non-students by residential and non-residential land-use types. In addition to the duration of the trip, the perceived neighborhood-level characteristics are critical for active transportation. Improving neighborhood conditions and their perception by the public can enhance the attractiveness of active travel, more specifically cycling for longer commutes. Based on the study findings, the paper discusses strategies to promote the use of active transportation in the context of a country in the Global South.

This paper shares the findings of an active transportation (AT) study conducted in the context of a city in a developing country. First, a list of AT indicators was developed based on the literature review and expert opinion survey. Second, a face‐to‐face survey was conducted to collect information on individuals' socio‐demographic characteristics, travel behavior, AT mode choice, and their perceptions regarding the AT conditions in their neighborhoods. Analysis of the survey results suggests that several socio‐demographic characteristics are associated with AT use. For example, young adults and individuals with low income are the primary users of AT. Also, results suggest that students are mainly active commuters. The ratio of AT use increases with the number of bicycles in the household. Individuals tend to walk more when travel duration is less than 10 minutes. Educational areas are perceived as safer and convenient areas for using active modes of transport compared to other land‐use types. Also, a higher proportion of active commuters perceive local roads to be safer from vehicular traffic compared to main roads. Many sectors such as planning, transportation, health, and education as well as non‐government organizations will be benefited from this study.

This paper examines the impacts of smartphone application usage on mobility choice dimensions, such as individuals’ visits to new places, individuals’ trips planned in groups, their participation at social gatherings, and vehicle kilometers traveled. It uses data from the Smartphone Use and Travel Choice Survey 2015, which was conducted exclusively on smartphone users of Halifax, Canada. A latent class random parameter logit (LCRPL) modeling technique is applied in this study that provides a better understanding of the effects of smartphone application usage on mobility choices. The model results offer behavioral insights regarding the influence of individuals’ attitudes, travel characteristics, built environment and accessibility measures on the relationship between smartphone application usage and mobility choices. For instance, living in the higher mixed land-use areas, individuals are less likely to increase their vehicle kilometers traveled due to smartphone application usage, especially if they are tech savvy. Such individuals tend to increase their participation in social gatherings. One of the unique features of this study is that it explores the effects of individuals’ smartphone application usage on mobility choices in terms of their attitudes. The study reveals that in case of people with positive attitude towards sustainable travel, smartphone application usage tends to decrease vehicle kilometers traveled, new place visits and planned group trips, however, increase participation in social gatherings. Results of this study provide critical behavioral insights that could be useful for transportation planners and policy makers to develop flexible policy interventions.

This paper aims to explore the covariates that affect the use of smartphones for trip planning as well as the covariates of perceived impact of smartphone use on travel outcomes. Trip planning activities considered in the study include performing online tasks, deciding departure time, mode choice decision, deciding trip destination and communicating and coordinating trips by using smartphones. Travel outcomes include the number of new places visited, social gatherings attended and trips planned in groups. This study emphasizes the role of built-environment and attitudinal variables on smartphone use for travel. Following ordered response and binary choice modeling approach, this study identifies that age and attitudes (toward smartphone use and environment) play a significant role in using smartphones for trip planning as well as shaping travel outcomes. Millennials (16–34 years) are more likely to use smartphones for trip planning and perceive increase in travel outcomes compared to other age groups. In addition, tech-savvy attitude is positively associated with trip planning and travel outcomes. However, the influence of built-environment characteristics is comparatively low in relation to the other attributes considered in the analysis. The study also finds that those who highly use smartphone apps for social networking purposes are more likely to perceive increase in their travel outcomes.

This paper explores the use of smartphone applications for trip planning and travel outcomes using data derived from a survey conducted in Halifax, Nova Scotia, in 2015. The study provides empirical evidence of relationships of smartphone use for trip planning (e.g. departure time, destination, mode choice, coordinating trips and performing tasks online) and resulting travel outcomes (e.g. vehicle kilometers traveled, social gathering, new place visits, and group trips) and associated factors. Several sets of factors such as socio-economic characteristics and travel characteristics are tested and interpreted. Results suggest that smartphone applications mostly influence younger individuals’ trip planning decisions. Transit pass owners are the frequent users of smartphone applications for trip planning. Findings suggest that transit pass owners commonly use smartphone applications for deciding departure times and mode choices. The study also identifies the limited impact of smartphone application use on reducing travel outcomes, such as vehicle kilometers traveled. The highest impact is in visiting new places (a 48.8% increase). The study essentially offers an original in-depth understanding of how smartphone applications are affecting everyday travel.

This paper examines the influence of the smartphone-based social networking and transport-support application usage intensity on travel behavior, specifically on vehicle kilometer traveled during weekends. It utilizes data from the ‘Smartphone Use and Travel Choice Survey 2015’, which was exclusively conducted on smartphone users in Halifax, Canada. One of the unique features of the study is that it explores the direct and indirect effects of individuals’ attributes, including socio-demographic, neighborhood and attitudinal attributes, on weekend travel and smartphone application usage intensity. Model results suggest that higher usage intensity of social networking applications and pro-environmental attitude decrease individuals’ probability of higher weekend vehicle kilometer traveled. While lower age group people tend to have higher social networking and transport-support application usage and lower weekend vehicle travel, middle age individuals more likely to have lower social networking application usage and higher weekend vehicle kilometer traveled. Interesting results are observed in relation to the direct and indirect effects. For instance, positive direct effect of land-use index on weekend vehicle kilometer traveled indicates individuals’ tendency to perform higher weekend travel by vehicles while living in higher mixed land-use areas. However, negative indirect effect suggests that individuals living in higher mixed land-use areas may indirectly decrease their probability of higher weekend vehicle kilometer traveled due to lower transport-support application usage intensity and pro-environmental attitude.
