1. Determine the service flow rate with a level of service B for asection of 4-lane freeway (2 lanes in each direction) with 10-ft lanes and obstructions 4 feet from the traveled pavement on oneside of the roadway. The section has a 5% grade 0.95 miles long. It is to accommodate 8% heavy trucks and buses and 4% recreational vehicles. Based on local studies, an adjustment factor for thedriver population, fp , 0f 0.90 is indicated. The design speed is60 mph.
