by the number of TSGIs, the Campbell Road
pedestrian refuge doesn’t meet the standards – the
minimum depth needs to be 1.4m. A continuous
zebra crossing here would be over 10m, so that
wouldn’t meet the standards either.
Where possible, the design has attempted to put in
1.8m wide refuges, however the overall small
footprint of the intersection and multiple lane
arrangement, coupled with the high traffic flows
creates a significant challenge to cater for the
transport mode demands. The proposal retains the
status quo of the zebra design and lane layout, and
raises the existing arrangement of the zebra
crossings.

Tables have a 1:10 approach ramp, 6m level top and
a 1:10 departure ramp. The tables are to be 75mm
high. Footpaths to be upgraded to provide a flush
crossing surface with the table.
