MEETING, WASHINGTON OCTOBER 2002
2CROSSING LOCATION
- Use signalised crossings
- On exit, not more than 20m from roundabout
- On exit, taper should be complete before crossing
- On the entry, between 20 and 50m from roundabout

MEETING, WASHINGTON OCTOBER 2002
3CROSSING LOCATION
- Stagger the crossings
- Pedestrians on central reserve look towards
traffic they are about to cross - Control speed on exit from roundabout- exit
deflection as opposed to easy exit?

4COLOURED SURFACING
- Coloured surface warns drivers of hazard ahead
- Surfacing material should be a high friction
material - If possible, define nationally what colour
represents what hazard - Needs maintenance to refresh colour

5VEHICLE DETECTION
- 1. Use above ground detection
- 2. No need to detect trapped vehicles
- as signals revert to vehicle green

6PEDESTRIAN DETECTION
- Simplest is push button giving fixed pedestrian
timings - Newest equipment uses push-buttons and 2 types of
pedestrian detector - 1. Kerbside detector
- see pedestrians waiting to cross
- - if pedestrians leave, demand cancelled
- 2. On crossing detector
- extends crossing period between min and max
times - just like vehicle actuation - - short crossing period for fast/fit
pedestrians - - long crossing period for
- large numbers of pedestrians
- slow/disabled pedestrians

7EQUIPMENT TO ASSIST VISUALLY IMPAIRED
- BLEEP SWEEP equipment
- Tactile revolving cone
- Ticking boxes
- Tactile paving surfaces

8BLEEP SWEEP EQUIPMENT
Bleeper
- Bleeper gives intermittent noise during
invitation to cross period - Second is intended to be localised to waiting
area - Automatic control of sound output level
- Located a little above head height
- Intended to allow 2 or more adjacent crossings to
operate without mutual interference - Difficult to set up and maintain

9TACTILE REVOLVING CONE
WAIT
PUSH BUTTON
REVOLVING KNURLED CONE
- Located in standard position under the standard
wait light unit - Cone revolves during invitation period
- Effective for both the visually impaired and the
deaf - Avoids confusion between adjacent crossings
- Technically best solution

MEETING, WASHINGTON OCTOBER 2002
10TICKING BOXES
- Emits an intermittent low-volume sound constantly
when crossing green to traffic - Designed to guide the visually impaired to
crossing control unit - Automatic volume control to match background
noise level - Changes to Cross now noise during invitation
period - Some questions about annoyance of constant noise
to nearby residents/workers - Widely used in Australia and some European
countries

11TACTILE PAVING SURFACES
- Designed to provide guidance/information to the
visually impaired pedestrian - Different surface textures give specific
information - Surface to identify presence of pedestrian
crossings - General application in the UK
- Information on full range of surfaces and uses in
the Department for the Environment, Transport and
the Regions (now Department for Transport)
document Guidance on the use of Tactile Paving
Surfaces

12LIGHTING AT PEDESTRIAN CROSSINGS
- Lighting should be good - i.e. uniform brightness
- BRIGHT does not equal GOOD!
- Brilliance of crossing lighting should be similar
to roadway and surrounding area - Contrast to high light crossing can be obtained
through different colour tone to lighting.

13ROAD SIGNS THE VISUALLY OR MOBILITY IMPAIRED
- Keep signage well away from areas where
pedestrians wait to cross - Large bollards can hide people in wheelchairs or
children
