Design trials research
The report produced for Guide Dogs research, by RambŘll Nyvig published in early 2007, identified a number of potential delineators which might be appropriate for use in shared surface streets. These included tactile guidance paving, different kerb profiles and two different kerb slopes.
We tested the effectiveness of these delineators working in conjunction with University College London at its Pedestrian Accessibility Movement and Environment Laboratory (PAMELA).
Each of the proposed delineators was tested for ease of detection and use by blind and partially sighted people, and also for ease of crossing by wheelchair users and people with walking difficulties.
None of the delineators (in the forms tested) were found to meet the needs of both groups of users. Consequently Guide Dogs would not consider them to be suitable for use to delineate a ‘safe space’ in shared surface streets where vulnerable pedestrians would be able to move around with confidence. Two designs were identified, however, as warranting further research: those being the central delinator and a slope.
