A four-lane freeway (two lanes in each direction) in rolling terrain has a peak 15-min flow rate of 1800 veh/h during the peak hour. The traffic stream contains 6% trucks, 3% buses, and 5% recreational vehicles. What is the analysis flow rate (i.e., the peak 15-min demand flow rate under equivalent base conditions in pc/h/ln)?
