The predicted traffic mix of a proposed four lane urban non-interstate freeway: Passenger cars (4.44KN/axle) = 69% 2-axle single unit trucks (22.2kN/axle) = 20% 2-axle single unit trucks (40KN/axle) = 5% 3-axle or more single unit trucks (100kN/axle) = 4% 3-axle or tractor semitrailers and combinations (90kN/axle) = 2% %3D %3D %3D The projected AADT during the first year of operation is 3500 (both directions). If traffic growth rate is estimated at 4%, percent of traffic on the design lane is 42%, pt =2.5 and SN =3, determine the design ESAL at the design life of 20 years.

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.
