Safe Blind-Turns: Cross-Circuit Warning and Motion Power

The study aimed to reduce cases of accidents caused by blind U-turns, and as such, an innovative cross-circuit indicator system was developed. The existing road signs and lamps were ineffective in such a case due to lack of visibility and drivers’ non-adherence, leading to accidents. Therefore, the new system applied motion-powered sensors to identify vehicles on the roads with blind spots or U-turns. Also, the motion or energy produced during U-turns was captured to produce electrical power that was fed to the indicator. As a result, with the advanced warning of a possible U-turn, visibility was incorporated using the same system for safer driving practices, effective in addressing the identified issues of poor visibility and driver speed miscalculations that caused most of the accidents.
