Question 1. Please draw a typical four-leg signalized intersection (with left-turning at all legs) and a four-leg signalized intersection with a median U-turn crossover (shown below) using CAD or similar software.

Question 2. Please use realistic dimensions.

Question 3. Scale is advised as 1:500 (you can use other scale but please indicate the scale on your drawings).

Question 4. Show all lanes and traffic direction arrows,

Question 5. Indicate the conflict points at a four-leg signalized intersection and four-leg signalized intersection with a median U-turn crossover (use different markers or colors for merging diverging and crossing).

Question 6. Tabulate the conflict points (merging, diverging and crossing) of two intersections and interpret the advantages and disadvantages of establishing a four-leg signalized intersection with a median U-turn crossover.
