An urban freeway is to be designed using the following information. AADT = 52,500 veh/day K (proportion of AADT occurring during the peak hour): 0.12 D (proportion of peak hour traffic traveling in the peak direction): 0.65 Trucks: 8% of peak hour volume PHF = 0.94 Lane width: 12 ft Shoulder width: 10 ft Total ramp density: 0.5 interchange/mile; all interchanges are to be cloverleaf interchanges Terrain: rolling Determine the number of lanes in the peak direction required to provide LOS C. (Assume commuter traffic and assume no RVs.)_______ lanes Show all calculations required. (Calculate your answers for the peak direction only. Enter fHV, the peak hour volume in veh/h, the free flow speed in mi/h, the demand flow rate in pc/h/ln, the mean speed in mi/h, and the density in pc/mi/ln.) fHV ________ peak hour volume___________veh/h free flow speed_______ mi/h demand flow rate___________ pc/h/ln mean speed_________ mi/h density_____________ pc/mi/ln.

Capacity and Level of Service at Intersections

The term capacity is associated with transportation engineering. Capacity helps to understand how many pedestrians or vehicles can be handled by a transport facility. Level of service is also a term associated with transportation engineering. The level of service indicates the performance of the transport facility.
