Motor vehicle crash data linkage has emerged as a vital tool to better understand the injury outcomes and the factors contributing to crashes. This systematic review and meta-analysis aims to explore the existing knowledge on data linkage between motor vehicle crashes and hospital-based datasets, summarize and highlight the findings of previous stu...

With the surging usage of e-scooters worldwide, there is a growing interest in understanding different aspects of e-scooters trips and their impact on urban mobility. Further, the emergence of this new mode of transportation has led to questions regarding the spatial accessibility of e-scooters and understanding how the built environment and urbani...

Reducing the response time of emergency vehicle(EV) is accompanied with many health and traffic-related benefits. New technologies can be utilised in creating a cooperative lane-changing behaviour for surrounding traffic to reduce the response time. In this research, the influence of lane-changing behaviour on the delay of EV and surrounding vehicl...

Introduction: Traffic crash reports lack detailed information about emergency medical service (EMS) responses, the injuries, and the associated treatments, limiting the ability of safety analysts to account for that information. Integrating data from other sources can enable a better understanding of characteristics of serious crashes and further...

The emergence of micromobility services in the form of dockless shared e-scooters has resulted in a wide range of behavioral changes in urban environments. In order to effectively steer these changes towards sustainability targets, the characteristics of e-scooter trips and users’ behaviors should be understood further. However, there is a lack of...

This study explores how factors, including weather, day of the week, holidays, and special events, influence the trip frequency of two micromobility modes, shared e-scooters and bikeshare, in Louisville, Kentucky. Negative binomial generalized additive models (NBGAM) were estimated to model the trip frequency of each mode. NBGAM provides a rigorous...

The COVID-19 outbreak has brought up challenges in numerous aspects of everyday life that require revisiting both the concepts and policies that are supposed to help adjust to the new situation. In this sense, public transit systems have undergone many changes while adapting to the new situation. Stay at home orders or avoid using public transporta...

Transportation agencies seek efficient methods to figure out how to reduce the severity of crashes and prioritize safety improvement investments. Police-reported crash data are the main source of information for transportation engineers to systematically address safety. However, other additional data sets exist that can help explain factors associa...

In this study, emergency medical services times, along with other crash-related explanatory variables, have been used to investigate influential factors on injury severity. To overcome the complexity of emergency medical services times impact on crash outcome, the interaction effects of EMS times and injury location on the body were also investigat...

Shared e-scooters have become a common mode of transportation in many cities around the world. E-sooters provide convenient and quick rides for short distances and can act as a connection for first/last mile trips. To date, limited studies have explored the spatial variation of e-scooter trips and there is knowledge to be gained by investigating va...

Introduction: Reducing the severity of crashes is a top priority for safety researchers due to its impact on saving human lives. Because of safety concerns posed by large trucks and the high rate of fatal large truck-involved crashes, an exploration into large truck-involved crashes could help determine factors that are influential in crash severi...

Shared E-Scooters have become popular in many cities around the world. E-Scooters provide convenient and quick rides for short distances and can act as a connection for first/last mile trips. This study aims to identify spatial factors associated with scooter trips. To accomplish this, a Generalized Additive Modeling (GAM) approach was applied to a...

The number of studies that explore contributing factors that encourage individuals to do more walking trips is proliferated in recent years. However, there is still a lot to know about differentiating between short and long walking trips and their associated influencing factors. The current research investigated the impact of the influencing factor...

Background and purpose: The world's elderly population has been dramatically growing during the last few decades, and therefore, a big challenge for many societies will be to meet the future needs of this group especially their health problems. Promoting walking as an active mode of transportation in daily travel could have many benefits on the hea...

In recent decades, enhancing the share of walking in individuals’ daily trips has become a priority for transportation policymakers, urban planners and public health researchers as an interdisciplinary area. In this regard, determining influential factors on walking has become a matter of contention to move toward a sustainable mode of transportati...

In recent decades, many studies investigated the influencing factors on walking. Although there are lots of finding about these factors, only a few of them conducted to differentiate between short and long walking trips and their associated influencing factors. Current research investigates the impact of the influencing factors on the share of walk...

The world's elderly population has been dramatically growing during the last few decades and therefore, a big challenge for many societies will be to meet the future needs of this group especially their health problems. Promoting walking as an active mode of transportation in daily travel could have many benefits on the healthy lifestyle of the eld...

Development of non-motorized modes of transportation has recently become a common trait among urban planners toward sustainable transportation, and walkability has been introduced as one of the most interesting concepts in the past two decades. A number of researchers put efforts to develop walkability indices (WIs) to show the status of walkabilit...

In this paper, the influence of traffic ethics on driving is investigated and modeled from sociological perspective. The model is developed based on the survey results of 215 drivers who received driving tickets in Tehran, Iran. In this paper, the traffic ethics is considered as a criterion of drivers’ obligation to obey traffic rules. To evaluate...
