A multilane highway (three lanes in each direction) is on level terrain. The free flow speed has been measured at 50mph. The peak-hour directional volume is 1500 vehicles with 10% heavy vehicles, and PHF is 0.9. If the proportion of vehicles types and peak-hour factor remains constant, how many vehicles can be added to the directional volume before capacity is reached?

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.
