Transportation safety is a public health issue, and our current framework is part of the problem

Traditional transportation safety frameworks like the three Es (Engineering, Enforcement, and Education) are impeding strategies that will reduce traffic deaths and improve overall population health, says a new study. The study introduces the Safe Systems Pyramid, a framing of the Safe Systems approach designed to prioritize policies and programs that incorporate health principles into transportation decision making.  By combining public health efforts with transportation strategies and practices, the authors propose an alternative approach that moves away from identifying crash outcomes and toward addressing the causes of safety crises., the authors propose an alternative approach away from identifying crash outcomes and toward addressing the causes of safety crises. 

People like being home, and that offers some benefits

Changing travel behavior may be confounding our traditional notions about transportation demand as evidence shows that people were staying home more even before the pandemic. The debate continues as to whether remote and hybrid work schedules lead to less driving overall, or just distribute driving differently throughout the day. Yet scholars are finding that flexible, work-from-home schedules may be associated with people being more active. 

American adults forgoing needed healthcare due to transportation barriers

In the United States, the design of our transportation infrastructure to prioritize driving and parking produces a number of negative public health outcomes, including air pollution, deadly crashes, and increased social isolation. A new study highlights another issue: health care services are more difficult to access for those who do not own a vehicle and have limited access to public transportation. 

Drivers of pickups and SUVs more likely to strike pedestrians while turning

There is no doubt that Americans love big vehicles. In 2010 just under 53 percent of estimated new vehicle sales were made up of trucks and SUVs. That number has jumped to 78.5 percent in 2021 according to JD Power. Unfortunately, the rate of pedestrian fatalities has also risen during that time frame. Pedestrian deaths have increased by 46 percent in the last decade, according to the Governors Highway Safety Association, with over 6,500 pedestrians killed in 2020 alone. A new study provides one explanation for why these two trends may be connected.

Research bolsters the role of road design in protecting against distracted driving

Distracted driving has long been a concern of traffic safety advocates and transportation professionals, and the pandemic has potentially made things worse. Reports by data and insurance companies suggest distracted driving contributed to the dramatic recent surge in traffic deaths. Fortunately, a growing body of research shows how road design and the built environment can help make crashes involving distracted drivers less serious.

Micromobility in Cities, A History and Policy Overview (National League of Cities, 2019)

Bike sharing—both docked and undocked, manual and electric-assist—plus kick and electric scooters have become commonplace in cities across the U.S. But best practices are still emerging, and cities are often not sure if these new micromobility devices will bring positive or negative consequences to their transportation system and neighborhoods. The National League of Cities has provided a history of the rise of micromobility, a guide for what cities should think about as they move forward with regulation and policy, and finally case studies from across the country.

Real-time crash prediction models: State-of-the-art, design pathways and ubiquitous requirements (Accident Analysis and Prevention, 2019)

With the advancements in artificial intelligence, and multiple studies being focused towards developing real-time crash prediction models, the concept of a proactive safety management system has become very close to reality. The linked study conducts an extensive review of the existing real-time crash prediction models, systematically illustrating the various methodologies being used world-wide. It evaluates the universality, design requirements, and associated challenges of various models. The study aims to be a “one stop knowledge source” for future researchers and practitioners for transitioning from the existing real-time crash prediction conceptual models to a real-world operational proactive traffic safety management system.
