Given the following geometry of an intersection: Four lanes fornorth and southbound traffic; two lanes for east and west boundtraffic. The peak hour volume for: north bound traffic is 1400vehicles with 10% left and right turns, southbound traffic is 1100vehicles with 10% lefts and rights; East bound traffic is 550 vehicles with 15% lefts and rights; westbound traffic is 300vehicles with 15% lefts and rights.

a) What is the ratio of demand for time with respect for timeavailable?

b)If you add left turn lanes for north and southbound traffic, whatis the ratio of demand for time with respect to time available?

c) What is the demand for time if left turns are provided for allapproaches?
