    Older drivers are more likely to be involved in a lane change crash compared with middle-aged drivers. While a number of different blind spot warning systems and intervention systems exist, a more thorough understanding ...
  • Active and Adaptive Roadway Delineation Systems 

    Williams, Brian; Gibbons, Ronald B.; Medina, Alejandra (National Surface Transportation Safety Center for Excellence, 2017-10-13)
    Heavy fog presents a significant safety hazard to drivers by reducing their ability to see the roadway and other vehicles. Even so, drivers often fail to adjust their speed to account for the reduced visibility, resulting ...
