Advanced vehicle technologies have the potential to improve safety and convenience for drivers; however, in order to realize these benefits, it is important that drivers use the systems appropriately. Past research has documented gaps in drivers’ understanding of how new technology works and when it should be used. It follows that the interplay between a […]
Decarbonisation of road transport was until recently considered the most challenging part of the climate agenda. Still the ascent of electric vehicles is making significant advances possible while, at the same time, opening several new complex conundrums: integration of power and transport systems, establishing supply chains of needed materials and conversion of existing industries to […]
An overarching goal of road corridor projects is to reduce traffic delays and improve safety for all users, including drivers, pedestrians, cyclists, and delivery vehicles. Doing so often involves changing the way road users access sites along the road, such as by removing or relocating driveways; adding medians, turning restrictions, service and frontage roads, and […]
Use of DOT-compliant motorcycle helmets was 73.8 percent in 2023, not statistically different at the 0.05 level from 66.5 percent in 2022. The 2023 estimate is the highest ever recorded. The 2023 data collection occurred during the usual timeframe of early June, immediately following the Click It or Ticket campaign. There were 945 motorcyclists observed […]
The emergence of various new forms of urban mobility services in recent years has led to new pressures on curbside space. Municipalities, the entities frequently responsible for managing the curbside, are in many instances handling these growing pressures by reallocating portions of the curbside away from traditional uses (such as metered and residential parking) in […]
Dec. 2-6, 2024, marks Older Driver Safety Awareness Week. As the population of older adults (65 and up) continues to grow, promoting safe driving practices becomes increasingly important. According to the National Highway Traffic Safety Administration (NHTSA), 17% of licensed drivers in 2022 fell into the older adult category, totaling over 57.8 million people. In 2022, the number […]
The Systemic Safety User Guide is an update to the Federal Highway Administration’s Systemic Safety Project Selection Tool. The Guide presents a process for incorporating systemic planning into the safety management process. The chapters describe how agencies can identify focus crash types, facility types, and risk factors; screen and prioritize candidate locations using risk; identify […]
This report reviews and assesses driver monitoring systems (DMS) and related technologies for alcoholimpairment detection and SAE International Level 2 partial driving automation systems. For the review oftechnologies to identify driver alcohol impairment, 331 technologies were reviewed. The systems were classifiedas physiology-based, tissue spectroscopy-based, camera-based, vehicle kinematics-based, hybrid, and patent-stage systems. A key focus was […]
In recent years there has been a significant increase of the interest in additive manufacturing (AM; also frequently referred to as 3D printing), yet AM is largely unexplored within infrastructure projects. By harnessing the new capabilities of AM, researchers have managed to access unprecedented new design capabilities and operational flexibility (e.g., on-demand, tool-free production). This […]
Use of DOT-compliant motorcycle helmets was 73.8 percent1 in 2023, not statistically different at the 0.05 level from 66.5 percent in 2022. The 2023 estimate is the highest ever recorded. This result is from the National Occupant Protection Use Survey (NOPUS), the only survey that provides nationwide, probability-based, observed data on motorcycle helmet use in […]
