Problem Statemento Many bicyclists are injured due to car

related accidents on the road each year. o If a bicyclist could be warned of rear

approaching vehicles, this could greatly reduce number of bicyclist involved in accidents.

o Primary Goal - To design and develop a low cost vehicle alert accessory for cyclists

Concept Sketch

Functional Specso The device must communicate via the ANT+ protocol to an

Edge 500 Garmin head unit

o Must be able to detect cars going from speeds 10mph-70mph

o Must detect vehicles in the range 1m-100m behind the rear of the bicycle
