The project starts with a simple road-safety problem: on unfamiliar roads, drivers and motorcyclists can be unsure of the current speed limit, particularly where reminder signs are sparse or the limit changes along a route. A survey of more than 200 road users presented in the proposal found that 98% had sometimes been unsure of the limit.
The proposed solution is deliberately simple: painted reminder rings placed around lamp posts or other vertical street furniture at regular intervals. The number of rings communicates the speed limit — for example, two rings for 20 mph and three for 30 mph — creating a repeated visual cue without relying on additional large signs. The proposal favours weatherproof dayglow paint as a low-cost and durable treatment.
The concept is intended to complement existing road signs rather than replace them. By using infrastructure that is already present, the system aims to be fast to install, easy to understand and cost-effective, while helping drivers maintain awareness of the prevailing limit through areas where conventional reminders may be limited.
