In this section, we describe the design of a Cyber-Physical bicycle
system, which utilizes video processing to automatically detect
rear-approaching vehicles. The goals of our design are threefold.
First, the system must accurately detect and track vehicles
that approach from behind. Second, the system must be able to
alert a biker with enough time that the biker can take evasive action.
Third, the system should distinguish between vehicles that
approach a biker in both safe and unsafe manners. There are a number
of significant challenges to overcome when building a system
to automatically detect rear-approaching vehicles.
