Pedestrian distraction at roadway crossings has been correlated with a higher risk of pedestrian-vehicle collisions due to the pedestrian's cognitive, visual, and motor attention being drawn to a wide variety of secondary tasks.

Permeability, effects of age, and water table fluctuations were
studied for nine drainfields in five soil types ranging from well to

two in Amity, two in Concord, and one in Dayton soils. Before
permeability of drainfields could be evaluated, methods...
