WebDesign guidance for curvature of high-speed (50-mph or greater) or non-urban facilities is shown in Table 2-4 and Table 2-5 for maximum superelevation (e max ) rates equal to 6 percent and 8 percent respectively. For high-speed design conditions, the maximum allowable deflection angle without a horizontal curve is 30 minutes.
Webc. Stationing. As with a single curve, there are two paths to the EC from the BC. One goes up and down the original tangents, the other along the curves. Whether a station equation is used at the EC depends on how the entire alignment is stationed. Refer to the Station Equation discussion in Chapter C.
