Simple Awareness of Vehicles and Assorted Night Traffic(SAVANT) Senior Design Project 2012 Team Xia Geoff Hermann, Ben Bromberg, Rodrigo Bismonte, Patrick Estabrook
Problem Statement • We wish to reduce injury and death to pedestrians and bikers caused by lack of visibility.
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

MDR Goals/Progress • 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 basic transmit/receive software for each part of the system • ATTiny, XBee, BeagleBoard • IV. Prototype • Get the transmit/receive system working in the proposed fashion
MDR Goals/Progress • 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) prototype ped TX
MDR Goals/Progress • Cost Breakdown
MDR Goals/Progress • Cost Breakdown
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
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
