The Intersection Design course will address how design affects the safety and capacity of the intersection. The course will start with the determination of whether to signalize an intersection. Signal warrants will be discussed and the class participant will conduct a warrant exercise. For the rest of the class geometric design issues will be addressed. Design features covered include deceleration lanes, corner clearance, vehicle corner clearance, and corner radiu
Also, functional areas of an intersection will be defined and an exercise to calculate the functional area will be conducted. A quick review of roundabout design and a comparison will be made of roundabouts versus intersections will be presented.
Finally, the class will end with a summary discussion of how design affects intersection capacity.
