Simple Awareness of Vehicles and Assorted Night Traffic (SAVANT)

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

2. Outline • Problem Statement • Our Proposed Solution – SAVANT • System Overview • Block Diagram • Feasibility for SDP • Plan of Attack • Deliverables • MDR and FDR • Questions

3. Problem Statement • We wish to reduce injury and death due to road collisions caused by lack of visibility.

4. 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. 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

6. Overview • Problem Statement • Our Proposed Solution – SAVANT • System Overview • Block Diagram • Feasibility for SDP • Plan of Attack • Deliverables • MDR and FDR • Questions

7. System Overview • Users of the road wear GPS devices transmitting their location • Motor vehicles have receivers and transmitters • Displays the location of received GPS information on the windshield (Heads Up Display) SimpleAwarenessofVehicles andAssortedNightTraffic

9. System Overview 32 ft 103 ft SAVANT

10. System Overview 18 ft SAVANT 14 ft

11. 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

12. Outline • Problem Statement • Our Proposed Solution – SAVANT • System Overview • Block Diagram • Feasibility for SDP • Plan of Attack • Deliverables • MDR and FDR • Questions

13. Feasibility for SDP • Challenges for Electrical Engineering • Design of Transmitter/Receiver Components • Identifying between two signals • Doppler Effects on transmission • Making device wearable (durable, movable, lightweight) • Power issues • Challenges for Computer System Engineering • Software design for Automobile Receiving Element • Keeping track of specific bikers/pedestrians • Simplify Open Street Map data into display • Make clear/not distracting HUD.

14. Feasibility for SDP Cost for one CAR and one PED modules Cost for one CAR and two PED modules • Cost Breakdown

15. Plan of Attack • I. Learning Phase • GPS, XBee, ATTiny, BeagleBoard • II. Communication Phase • Getting all the components talking to one another • Make connections, send and receive data • III. Software Phase • Write the software for each part of the system • ATTiny, Xbee, Beagleboard • IV. Prototype • Get the transmit/receive system working in the proposed fashion

16. Plan of Attack • I. Learning Phase • Task 1 - (car, ped) learn about GPS modules • Task 2 - (car, ped) learn ATTiny programming software, procedure • Task 3 - (car, ped) learn about XBee programming, TX and RX • Task 4 - (car, ped) learn about BeagleBoard programming • II. Communication Phase • Task 5 - (car, ped) interface GPS with ATTiny microprocessor • Task 6 - (car) interface GPS with BeagleBoard • Task 7 - (ped) interface ATTiny with XBee module • Task 8 - (car) interface BeagleBoard with XBee module (TX, RX) • III. Software Phase • Task 9 - (ped) write software for ATTiny microprocessor • Task 10 - (car) write transmitter software for BeagleBoard • Task 11 - (car) write receiver software for BeagleBoard • IV. Prototype Phase • Task 12 - (car) prototype car TX/RX • Task 13 - (ped) protype ped TX

17. Gantt Chart Geoff Patrick Ben Rodrigo

18. Spring Semester Tasks • Extending software for multiple transmitting and receiving devices • Power circuits for car module and pedestrian module • Battery considerations • Power management in software • Printed circuit board design for pedestrian module • GUI design for car module • Final enclosure designs

19. Deliverables • Midterm Design Review • Working receiver and transmit circuit on breadboard • Final Design Review • 1-2 working bike/pedestrian transmitters (depending on budget) • Receiver installed in car • On-Windshield Display
