CAI

In Barcelona, 40% of road accidents are caused by bicycles and electric scooters (Guardia Urbana, 2021). Bicing is currently the most widely used public bike-sharing option in Barcelona.

 

CAI's target is to detect Bicing users who have exceeded the permitted alcohol level and prevent them from using the service. For this problem a theoretical prototype is created, handlebars with transdermal sensor which measures the TAC (transdermal alcohol content) and converts it into BAC (blood alcohol content) by using a biosensor.

 

The final prototype is a simulation and uses sensors such as "force sensitive resistor" (integrated in the handlebar of the bicycle to simulate when the user presses) and "servo motor" (to lock or unlock the bicycle from the programmed amount).
