upgrade - tgsi


As part of the Western Roads Upgrade in Melbourne, GTA Consultants worked with WBHO to provide guidelines for Tactile Ground Surface Indicators (TGSI) along adjacent pedestrian amenities. To create this solution, GTA’s way-finding specialist worked with the client to inform them on the use of TGSI and how they could be implemented using a human-centred design approach.

While Australian Standards provide reference for the application of TGSI, they are not always fit-for-purpose and lack clarity in certain contexts. GTA's strategy therefore focused on interaction with shared path line marking and integration with cross walks where pedestrians with vision impairment would be unfamiliar with the environments alongside cyclists and other active travel modes.



In addition, the approach took into consideration the nearby facilities that met accessibility standards as per the Disability Discrimination Act (DDA) and which would be of value to users, such as public transport, and health services. The TGSI application was grounded in its context and provided directional information to amenities surrounding the upgraded pedestrian paths.

Through a human-centred design approach, GTA delivered an outcome that focused on the users’ perspective as opposed to one driven by a standards or a traditional civil engineering perspective to shared paths. The result supports the needs of pedestrians with vision impairment and provides best practice for the application of TGSI according to DDA requirements.
