2. Retrofit raised crossings improve safety and certainty for all road users due to safer vehicle speeds.
3. Refer MUTCD Part 13 for details of pavement markings and signs.
4. Refer MUTCD Part 13 Figure 11 for details of pavement marking approaching the blister islands.
5. Streetlighting to be installed in accordance with AS 1158.
6. In constrained environments, adopt the following in this order to achieve the desired outcome:
Remove the departure kerb build-out;
Reduce the 2.0m separation on the top of the hump to 1.0m; and
Reduce the width of the cycle track.

Purpose
Achieve homogeneous speeds for all road users (<30kmh).
Design with clear priority and no confusion for any road user.
Function
Urban area intersection of Collector Road and Local Access "mixed-use" street.
Considerations
Safe design outcome, fewer conflict points than regular give-way intersection, safe speed at
conflict points resulting in lower severity crashes, clear priority.
Relatively high capacity.
Direct and attractive for bicycle traffic.
Two-way bicycle facility at roundabouts is not recommended due to crashes caused by cyclists
approaching from unexpected direction.
Design vehicles (8.8m service vehicle) must negotiate at low speeds (<30kmh) driving over the
centre island apron.

Function

Considerations

Relatively high capacity.
Two-way cycle tracks on roundabouts work well where bicycle traffic continues on a two-way
path on one side of a major road. However, two-way cycle tracks on roundabouts present an
additional driving task for drivers of motor vehicles who may not thoroughly check to their left
side where bicycle riders may be approaching from the anti-clockwise direction. Where two-way
cycle tracks are constructed, radial roundabout design, conflicts located on raised priority
crossings and two-way line-marking to highlight two-way bicycle traffic is required.
Direct and attractive for bicycle traffic.
Design vehicles (8.8m service vehicle) must negotiate at low speeds (<30kmh) driving over the
centre island apron.
