4) Determine the level of service (LOS) for a freeway segment with the following data. Show all steps involved. Demand volume (3452 vehicle per hour) ● • Number of lanes (3 lanes in one direction) • Width of lanes (11ft per lane) Lateral clearance on the right side of the freeway (4 ft) Total ramp density (2 miles between ramps, or 0.5 ramps per mile) Percent of heavy vehicles (5% trucks/buses and 0% recreational vehicles) Peak hour factor (0.927) I Terrain (level) ● Driver population factor (familiar drivers) ● ● ● ● 1 ●
Given that :-
A freeway segment with the following data :
Demand volume = (3452 vehicle per hour)
Number of lanes = (3 lanes in one direction)
Width of lanes = (11 ft per lane)
Lateral clearance on the right side of the freeway = (4 ft)
Total ramp density = (2 miles between ramps, or 0.5 ramps per mile)
Percent of heavy vehicles = (5% trucks/buses and 0% recreational vehicles)
Peak hour factor = (0.927) Terrain (level)
Driver population factor = (familiar drivers)
Require that :-
the LOS for this freeway segment =?
Explanation :-
Level of Service (LOS) is a qualitative measure used in transportation engineering and planning to assess and describe the quality and efficiency of transportation systems, particularly for roads, highways, intersections, and other elements of the transportation network. LOS is commonly used to evaluate the performance of transportation facilities from the perspective of users, such as drivers or transit passengers. It provides a framework for characterizing the operating conditions and service quality experienced by travelers.
