Agencies that aspire to achieve zero traffic fatalities need to know where to invest for the biggest crash reductions. Advances in artificial intelligence are allowing DOTs to leverage their existing camera technology in order to extract large quantities of data that can then inform decisions about how to improve or control intersections. The city of Bellevue, WA, recently announced a plan to study footage from its traffic cameras in order to “analyze the correlation between past collisions” and near misses, according to a press release.
“[NYC]DOT found little concrete evidence that device-induced distracted walking contributes significantly to pedestrian fatalities and injuries.” So concludes a recent report examining whether device-distracted walkers are killing themselves by stepping out in front of motor vehicles. It’s dangerous driver behavior—speeding and failure to yield—that is killing pedestrians.
Pedestrian bridges may help keep people away from heavy traffic, but only if people are willing to use them. And that often isn’t the case, according to a new study in Accident Analysis & Prevention. People will cross at street level to avoid tall or narrow, constrained bridges, according to the study, and they usually take extra precautions when crossing at street level.
The AAA Foundation reports that fatalities due to red light running is at a 10-year high, and more than half of the deaths were outside the offending car, including pedestrians, bicyclists, and those in other cars.
Most efforts to increase bike and walk accessibility focus on physical access. But the built environment is not the full story. A new study finds that certain attributes of the social environment also greatly affect the perception of walkability, especially among people of color.
Research and design are based on a test case human who stands in for the broader population. The default human that is the basis for research and design projects is usually a white adult male. As a result, projects often come to conclusions that do not address the needs of women, and some that are outright dangerous. Transportation projects and priorities are not immune to this bias.
Many imagine a future with fleets of autonomous vehicles seamlessly traversing road networks, wirelessly connected, perfectly aware of their surroundings and other vehicles, expertly avoiding conflicts. But what happens during the transition from manually-driven to fully-autonomous cars? As the share of AVs increases, some intersections may get more dangerous before they get safer, says a new paper by Australian researchers.
A study from Australia gives some insights into use of social media while driving, looking not just at the incidence, but also what deters the behavior. But while the study began as a general look at use of all social media by young drivers, it ended up focused on the use of Snapchat as the most common mobile phone behavior in the car.
Although cars are getting safer, saving drivers and passengers from dying on our roads and highways, the number of pedestrian and bicyclist deaths are increasing dramatically. The latest numbers from the National Highway Traffic Safety Administration Traffic Safety Facts show that while overall 2018 traffic fatalities decreased about one percent compared to 2017, pedestrian and bicyclist deaths increased four and ten percent, respectively.
Dense development patterns offer important safety benefits, according to new research from the University of Pennsylvania, but high-speed roads in dense suburban centers are deadly for pedestrians. This new study confirms what others have already shown—that attention to context is critical to safe road design.
