Chicanes
6.7.5 Chicanes will generally generate less vehicle
body rattle than road humps, unless a speed cushion
or road hump is incorporated. However, drivers may
show increased stop-start acceleration and braking
behaviour through chicane schemes, which can create
a noise nuisance (TAL 12/97).
6.7.6 Chicanes are not likely to cause any vibration
problems unless a speed cushion is included in the
design (see paragraph 4.5.8).
