A two-lane rural highway carries a peak hour volume of 465 (vph) and has the following characteristics: Roadway: 60mph design; 11 foot lanes, 2 foot shoulders; rolling terrain; 60% no-passing zones; length = 3 miles. Traffic: 70/30 directional split; 4% trucks; 2 percent recreational vehicles; 1 percent buses; PHF = 0.95 a) What Level of Service will the highway operate under during peak periods? b) What is the capacity of the highway? Explain why this is less than 2,800 (vph)?
