2.4.4.1Hump profiles for bus routes#

The design of vertical deflection devices shall consider the needs of buses. Humps on bus routes can be designed and positioned to minimise discomfort to passengers using long flat top humps with minimum grade on the ramps.

The following design requirements shall be adopted for road humps used on bus routes:

• Maximum hump height = 100 mm.
• Minimum hump length (excluding ramps) = 6.0 m for single unit buses and 8.0 m for articulated buses.
• Maximum ramp grade = 1:15.
