1 PEDESTRIAN CROSSINGS AT ROUNDABOUTS ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002 Location Coloured surfacing Detection - vehicle - pedestrian Equipment to assist visually impaired Lighting Road signs and the visually or mobility impaired Photos

2 CROSSING LOCATION ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON 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

3 CROSSING LOCATION ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002 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”?

4 COLOURED SURFACING ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON 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

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

6 PEDESTRIAN DETECTION ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON 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

7 EQUIPMENT TO ASSIST VISUALLY IMPAIRED ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002 “BLEEP & SWEEP” equipment Tactile revolving cone “Ticking boxes” Tactile paving surfaces

8 Bleeper “BLEEP & 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 ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002

9 TACTILE REVOLVING CONE ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON 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 WAIT PUSH BUTTON REVOLVING KNURLED CONE

10 “TICKING BOXES” ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON 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

11 TACTILE PAVING SURFACES ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON 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”

12 LIGHTING AT PEDESTRIAN CROSSINGS ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON 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.

13 ROAD SIGNS & THE VISUALLY OR MOBILITY IMPAIRED ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002 Keep signage well away from areas where pedestrians wait to cross Large bollards can hide people in wheelchairs or children

15 EXIT TO CROSSING ROUNDABOUT ACCESSIBILITY ISSUES WORKING GROUP MEETING, WASHINGTON OCTOBER 2002
