15. Continuous Two-Way Left-Turn Lanes <br />Continuous two-way-left-turn lanes (TWLTL) are a common access management <br />treatment when combined with driveway consolidation and corner clearance. TWLTLs <br />simultaneously provide a separate lane for left turning vehicles and property access. <br />Typically, they are used as the center lane of a five-lane roadway. A less common <br />design involves three lanes, a TWLTL in the center for left turns and one lane in each <br />direction for through traffic. <br /> <br />Recent theory suggests avoiding this design unless road right-of-way conditions are <br />restrictive. <br /> <br />16. Three-Lane Roadways With Two-Way Left-Turn Lanes Continuous <br />two-way left-turn lanes (TWLTL) are a common access management treatment. <br />Typically, they are used in the center of a four-lane roadway. However, a less- <br />common design involving three lanes – a TWLTL in the center for left turns and one <br />lane in each direction for through traffic – is being used more and more frequently. At <br />first, the idea of a three-lane road may seem strange. But under the right <br />circumstances they can work very well, operating better and more safely than a four- <br />lane undivided road. <br /> <br /> <br />17. Raised Medians At Intersections <br />Raised medians with left-turn lanes at intersections offer a cost-effective means for <br />reducing accidents and improving operations at higher volume intersections. The left- <br />turn lanes separate slower turning vehicles from through traffic and provide a protected <br />space for these vehicles to decelerate and turn. The raised median prohibits left turns <br />into and out of driveways that may be located too close to the functional area of the <br />intersection. <br /> <br />18. Continuous Raised Median <br />Continuous raised medians with well-designed median openings are among the most <br />important features for managing access to create a safe and efficient highway system. <br /> <br />19. Comparison Of Raised Median And Two-Way Left-Turn Lanes <br />Because raised medians are the most restrictive access management treatment, <br />building a raised median along an arterial is often very controversial among business <br />and property owners. Two-way left-turn lanes (TWLTL) are much less so. Business <br />persons and property owners feel that installation of raised medians will have a large, <br />negative impact on their customers, sales, and property values. Therefore, TWLTLs <br />are often suggested as a compromise solution. However, TWLTLs also represent a <br />safety compromise when compared to raised medians. They should be used with <br />care. <br /> <br /> <br /> <br /> 55
