4. Lahr,Fornberg,Groves,Henriquez,Lyons Purpose: Last year, there were 6.3 million car accidents, many of which were easily preventable. The purpose of our project is to develop a prototype system that will minimize these accidents and could eventually be expanded for commercial applications. S.A.F.E. (Systems for a Accident Free Enviroment)

5. Lahr,Fornberg,Groves,Henriquez,Lyons Description Modified RC car that can sense an accident threat and take corrective action Detects and Prevents multiple accidents Head on Collisions Merging into blind spots Backing into Stationary Objects

6. Lahr,Fornberg,Groves,Henriquez,Lyons Objectives Develop 4 Sensor Unit Array Sense Objects from Multiple Directions Detect Relative Speeds of Approaching Objects Develop Multi-Severity Level Avoidance System Gives Audio and Visual Warning to User when Object is Determined a Threat Overrides Manual Controls When Direct Avoidance Action is Needed

7. Lahr,Fornberg,Groves,Henriquez,Lyons Baseline Functionality Detects speed and distance from four directions Provide audio and visual warning when accident threat is detected Override control from user to prevent accidents
