This report provides a primer on location-based service (LBS) data and its uses in public transportation. It defines LBS data, describes the techniques for collecting and processing the data, and the key parties involved. The report highlights opportunities, limitations, and potential risks of using LBS data, based on the literature and interviews with transit agencies, […]
Several pieces of legislation have expanded DOT’s authority to combat human trafficking. These include expanding grant programs, requiring air carriers to train certain personnel, tracking air carrier training and tips, establishing the multimodal advisory committee, preparing a triennial advisory committee recommendations and best practices report, instituting a lifetime ban on Commercial Driver’s License holders who […]
The most basic truth about transportation too often goes unsaid: arriving safely is what matters most. We know this to be true, yet in our most familiar and common form of transportation – the use of roads by vehicles, pedestrians, and cyclists – tens of thousands of lives are lost every year in America. One […]
Traffic agencies are seeking solutions to the rise in pedestrian fatalities. A traffic control treatment that is gaining use is the pedestrian- or school-crossing warning sign with light-emitting diodes (LEDs) embedded in the borders (called LED-Em in this report). View the full study here.
Driving over the speed limit endangers all road users. By maintaining a safe speed on our roads, CMV drivers are able to better control their large vehicles and carefully react to changing road conditions, like traffic or weather impacts. The action is simple: maintain safe speeds to help save lives. For more information on this campaign, […]
The number of electric vehicles on the road increases exponentially every year. Due to the quieter nature of these vehicles when operating at low speeds, there is significant concern that pedestrians and bicyclists will be at increased risk of vehicle collisions. This research explores the detectability of six electric vehicle acoustic additive sounds produced by […]
Drowsy driving is a common phenomenon that increases the risk for fatal and injurious crashes. Technological innovations in the form of driver monitoring and notification systems may offer potential to reduce crashes due to drowsy driving. These systems monitor the driver’s drowsy driving state and issue alerts when the driver is classified by the system […]
In recent years, some localities have removed highways or built structures known as “highway caps” over sections of highways to repurpose the land for community or economic development. GAO identified 21 projects to remove or cap highways that received federal funding from fiscal years 2012 through 2021, the most current data available at the time […]
The current study was conducted to investigate the differences in injury outcomes between bicyclists struck by SUVs and those struck by cars. This study was designed to complement an earlier investigation using a similar methodology but focusing on pedestrian crashes. View the full study here.
NHTSA has released the 2022 early estimate report presenting the projections of traffic fatalities (42,795) and the fatality rate per 100 million vehicle miles traveled (VMT) (1.35) for 2022 (Early Estimate of Motor Vehicle Traffic Fatalities in 2022, DOT HS 813 428). That Crash*Stats shows a marginal decrease of about 0.3 percent as compared to […]
