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.

Understanding the nature of transit travel demand is at the heart of transportation policy making and the success of transit systems. Unfortunately, most existing studies focus narrowly on a single or a few transit systems or metropolitan areas to analyze the determinants of transit travel demand. It is, therefore, difficult to generalize their findings over a broader geographic scale. This paper examines and explores the determinants of transit travel demand by bus generalizable to the entire U.S. by investigating internal and external factors at the U.S. metropolitan statistical area (MSA) level for 2010. The authors collected and used data for all 358 MSAs nationwide. Internal factors are those that the transit managers and operators have some control over (e.g., transit supply, transit coverage), whereas external factors are those that they do not have control over (e.g., population density, vehicles per household). Several variables came directly from the U.S. Census Bureau and National Transit Database, whereas the authors constructed others using data from these two sources. The paper employs a log-log regression model to address the issues of non-normality, non-linearity, and heteroscedasticity. Findings suggest that internal factors tend to be significant predictors of travel demand by bus mode compared with external ones. As such, transit authorities have the ability to attract ridership by adjusting the influential internal factors under their control.

Because roundabouts offer so many beneficial features to a community, it is important that they are made as safe as possible for all users and comply with the Americans with Disabilities Act Accessibility Guidelines. There have been several studies conducted with the purpose of creating a safer crossing environment for visually impaired pedestrians at roundabouts. These studies focus on four methods: crosswalk placement, sound applications, signalized options, and automated yield detection. The purpose of this review paper is to explore these possible solutions, identifying the advantages and disadvantages, the practicality, and the overall performance of each solution. The research done here will also address which methods may be most appropriate for low volume roundabouts, moderate volume roundabout, and high volume roundabouts, as well as for one-lane roundabouts and two-lane roundabouts. When evaluating each option, it’s also important to estimate the effect it will have on the flow of traffic and travel demand management. An ideal solution will allow access to all users while maintaining the initial benefits of a roundabout.

This paper investigates the age and sex distribution of at-fault drivers with respect to fatal crashes on the interstate and state highways in Florida. The study finds that the younger and older drivers of both sexes are more likely to cause fatal crashes compared to the `average' middle-aged drivers. The female oldest (>=75 years) drivers are at highest level of vulnerability of causing fatal crashes followed by younger male drivers. The study recommends that more efficient and frequent public transit services should be provided to the older drivers, and their driving licenses should be renewed every year to ensure that they are in good physical and mental health condition to drive on the streets. Goal-based effective training and educational programs should be initiated for the younger drivers where such programs are not in place, and should be regularly monitored and evaluated to make them effective where they are in place.
