CROSSING LOCATIONCROSSING LOCATION
ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002
• 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
20m max
20m min 50m max

• 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”?

ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002
• 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
VEHICLE DETECTIONVEHICLE DETECTION
ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002
1. Use above ground detection
2. No need to detect trapped vehicles
as signals revert to vehicle green
PEDESTRIAN DETECTIONPEDESTRIAN DETECTION
ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002
• 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

• “BLEEP & SWEEP” equipment
• Tactile revolving cone
• “Ticking boxes”
• Tactile paving surfaces
Bleeper
““BLEEP & SWEEP” EQUIPMENTBLEEP & SWEEP” EQUIPMENT
• 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

TACTILE REVOLVING CONETACTILE REVOLVING CONE
ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002
• 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

ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002
• 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
TACTILE PAVING SURFACESTACTILE PAVING SURFACES
ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002
• 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”
LIGHTING AT PEDESTRIAN CROSSINGSLIGHTING AT PEDESTRIAN CROSSINGS
ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002
• 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.

• Keep signage well away from areas where pedestrians wait to cross
• Large bollards can hide people in wheelchairs or children
