RESUMEN
Abstract
The use of bicycles as a strategy for urban mobility has been steadily gaining ground worldwide. The lack of safety for cyclists remains one of the main factors limiting their use, particularly in cities where cycling infrastructure is insufficient. This study presents the design, evaluation, and implementation of a prototype intended to assist urban cyclists. The prototype was built with lateral and rear ultrasonic sensors, designed to detect the approach of vehicles in areas that constitute blind spots for cyclists. It also includes a visual alert panel mounted on the handlebars, a video recording camera, audible alarms, and a strobe light to enhance visibility. Sensor detection tests were conducted in a controlled environment. The results showed effective detection within an operational range of 300 to 2200 mm, with a relative error of 3.06%. Urban Cycle represents a viable and low-cost solution to improve cyclist safety in urban settings. Its implementation could reduce accidents caused by the invasion of the minimum lateral passing distance and promote the use of bicycles as a mode of transportation.
