Figure 7.27a shows the staggered unsignalized intersection of Patton Avenue and Goree Street. The distance between the T intersections is about 160 ft. The general layout and striping of the lanes at this intersection result in confusion to drivers and create multiple conflicts. Design an improved layout for the intersection for the traffic volumes shown in Figure 7.27b. Design vehicle is a passenger car.

Question

What will be an ideal response?

Answer 1

The staggered intersection of Patton Avenue and Goree Street will tend to cause confusion among drivers who expect to find cross streets intersecting perpendicularly, without the stagger as shown. The east leg of Patton Avenue should be realigned to produce a 4-leg intersection. Doing so should reduce the number of turning accidents, which appear to be the most common type of accident at this location. The high number of rear end accidents should also be reduced since motorist confusion will be reduced.
