Multimodal Level of Service for Urban Streets Page 48 EXAMPLE PROBLEM 2 DETERMINE LOS IMPACTS OF CONVERTING FROM 4-LANE TO 3-LANE CROSS-SECTION Objective: For a given set of modal demands, determine the impacts of converting a street from 4 auto lanes to 2 lanes plus two-way-left-turn-lane. Exhibit 24: Example Problem 3 Plan and Cross-Section Views 10 125 585 58 70 ft ROW 12 Bus Stop varies Key Issues: The key issue in this example is the tradeoff between the benefits to the bicycles of providing the bicycle lane and the reduction of through lanes for autos and buses from 4 lanes to 2 lanes plus a two-way left turn lane.
