Intersection Geometric Design II Author: Gregory Taylor Intersections are unique roadway elements where conflicting vehicle streams (and sometimes non-motorized users) share the same space. This area encompasses all modes of travel (pedestrian, bicycle, passenger vehicle, truck, and transit)as well as auxiliary lanes, medians, islands, sidewalks and pedestrian ramps. These may further heighten the accident potential... Learn More
