timer Asked: Dec 14th, 2015

Question description

A 3-leg intersection currently controlled by a yield sign connects Big Avenue, a 2-lane highway, to Blue Street, a 2-lane highway.  The approach speeds are 40 mph for Big and 30 mph for Blue.  The city has parking along Big Avenue and there have been several near misses (crashes avoided the last minute) in the past year.  The parking is located 200 ft from each corner of the intersection.  All lanes are 12 ft wide, the parking lane is 8 feet, the approaches have grades less than 3%, and the design vehicle is a single unit truck.  Determine: a.  (5pts) whether the parking interferes with the current design (need to justify the answer; a simple yes/no is not adequate); b.  (5 pts) if it interferes, the new distance(s) to resolve this problem; (5 pts) whether parking will interfere if a stop sign is used and the stop line is located 15 ft from the curb
