PEDESTRIAN CROSSINGS AT PEDESTRIAN CROSSINGS AT ROUNDABOUTSROUNDABOUTS

ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002WASHINGTON OCTOBER 2002

• Location

• Coloured surfacing

• Detection

- vehicle

- pedestrian

• Equipment to assist visually impaired

• Lighting

• Road signs and the visually or mobility impaired

• Photos

CROSSING LOCATIONCROSSING 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

20m max

20m min 50m max

CROSSING LOCATIONCROSSING 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”?

COLOURED SURFACINGCOLOURED 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

VEHICLE DETECTIONVEHICLE DETECTION

1. Use above ground detection

2. No need to detect trapped vehicles

as signals revert to vehicle green

PEDESTRIAN DETECTIONPEDESTRIAN 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

EQUIPMENT TO ASSIST VISUALLY EQUIPMENT TO ASSIST VISUALLY IMPAIREDIMPAIRED

• “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

• 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

BUTTON

REVOLVING KNURLED CONE

““TICKING BOXES”TICKING 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

TACTILE PAVING SURFACESTACTILE 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”

LIGHTING AT PEDESTRIAN CROSSINGSLIGHTING 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.

ROAD SIGNS & THE VISUALLY OR ROAD SIGNS & THE VISUALLY OR MOBILITY IMPAIREDMOBILITY IMPAIRED

• Keep signage well away from areas where pedestrians wait to cross

• Large bollards can hide people in wheelchairs or children
