Intersection Geometry Intersection Geometry is the way that two or more streets connect or cross each other. Most streets cross each other perpendicularly creating right angles. There are instances in Seattle, where streets meet at a “T” or a “Y”. In addition, there are some locations where more than two streets intersect. The geometry of the intersection depends on many variables including turning movement of vehicles, the width or the pedestrian crossing, width of right-of-way, sight distance, and topography. When intersections are designed these variables must be taken into account when configuring an intersection.
