Sight Line

The Sight Line system makes roadworks easier to deal with for everyone, particularly people with vision impairment. It is a simple set of physical changes to the signs and barriers used to indicated roadworks to make them easier to understand. The system also includes a digital layer which can provide more detailed information and warning of roadworks you may be approaching. This video explains a bit more about it.

The design of the system is based on insights from shadowing seven people with sight loss as they negotiated a series of real-world roadworks sites. Road workers were also shadowed to understand their procedures and requirements of their equipment.

Design ideas were prototyped and feedback from people with vision impairment, road workers, engineers, civil servants and mobility trainers was gathered and integrated into further iterations of the design.

The system was tested on a real street by 13 people with sight loss, 11 of whom found it to be an improvement over the existing equipment. We are currently looking for partners to help run an pilot of the system in day-to day use.

The Sight Line system was created in partnership with the Royal London Society for Blind People and the Royal College of Art Helen Hamlyn Centre for Design.
