3.9 Railings, Barrier Fences and Crash Cushions
3.9.1 General
3.9.1.1 The provision of a particular barrier fence along a road depends on many factors such as
pedestrian and traffic flow, road geometry, historic accident data, surrounding environment
and sometimes, consideration has to be given on aesthetic side. The Transport Department,
Fire Services Department, Hong Kong Police Force, Highways Department and other
concerned parties as appropriate should be consulted before a barrier fence is to be erected
or replaced on public roads.
3.9.1.2 Reference should be made to the Highways Department Standard Drawings for the detailed
information of barrier fences and railings that are commonly used on public roads. As for
vehicular parapets and pedestrian parapets on highway structures, Structures Design Manual
for Highways and Railways should be referred..
