VALUES OF K FOR VERTI ON The minimum length of vertical curvature suggested for a ram on aesthetics, but it ill very often not be possible to achieve gested in Table 4.2.2. Lower values are proposed in length in metres ecual to 0,6 o rounded off to the nearest 10 m. DESIGN SPEED (krnh) If a stalled vehicle blocks an off-ramp, blocking of the stop for future conversion of the TRH 1 7, Prelor~
ths are used in t e design of the terminal where the ram ic enters the intersecting road at an for vehicles entering or exiting from the through minal of the intersecting road should be designed in accordance with idelines in Chapter 8. Through road ramp terminals are discussed below. cing of successive terminals should be such that the manoeuvres carby a driver entering at one terminal are not hampered by vehicles entere next terminal downstream, The distance between an entrance and the exit should allow for weaving between the two terminals. An ex~t foldoes not caus successive exits could be cl river to be able to differenti nt design speeds that are likely to apply to the various cir- s of free-flowing ramp terminal are discussed in Subsection 9.2.1, o 1000 m, Th
