Electrical and Computer Engineering Department Senior Design Project 2012 Team Xia Geoff Hermann, Ben Bromberg, Rodrigo Bismonte, Patrick Estabrook Simple Awareness of Vehicles and Assorted Night Traffic (SAVANT)

2 Electrical and Computer Engineering Department Outline  Problem Statement  Our Proposed Solution – SAVANT System Overview Block Diagram Feasibility for SDP Plan of Attack Deliverables MDR and FDR  Questions

3 Electrical and Computer Engineering Department Problem Statement  We wish to reduce injury and death due to road collisions caused by lack of visibility.

4 Electrical and Computer Engineering Department Problem Statement  Over 700 cyclists killed by motor vehicles in 2008  Over 1,800 pedestrians killed by motor vehicles in 2010  Often, the drivers are not aware of pedestrians  Especially dangerous at night/low visibility and blind turns

5 Electrical and Computer Engineering Department Other Solutions  Radar/Camera Pedestrian Detection Most systems use radar or image detection Can detect pedestrians 80cm and taller Robust enough to be marketable (Volvo XC60) Alerts driver and even applies brakes Stop collisions at speeds up to 35 kph (~20 mph) Does not see pedestrians/bikers in blind spots Does not work in poor light/weather conditions Makes driver reliable on warning to brake Expensive/Only available in nice/new cars

11 Electrical and Computer Engineering Department System Overview  Advantages of SAVANT Provides info about pedestrians/bikers in all directions Cheap solution/easily installed in older vehicles Works regardless of lighting/weather Anticipate bikers and joggers around turns Gives driver more info without distracting/making driver reliant on device  Disadvantages of SAVANT Cannot “see” bikers or pedestrians without a transmitter Not accurate enough to judge distance for auto-braking
