Virtual Traffic signs Driver Attention System Final Presentation Students : David Eyal Handaly Gidi Semester : Spring 2004 Instructor : Kats Idan Cooperation with: Rout Link Sponsored by : Motorola IL Technion – Israel Institute Of Technology Electrical Engineering Department 15/04/04

Road Accidents The western world faces a severe hazard named Road Accidents. This hazard damaged nations economy and costs with life of thousands of people every year. Big efforts are made to reduce the hazard such as : - Velocity limitations,drivers age restraint. - Resources are invested in infrastructure. - Discouraging legislation.

Road Accidents Road accidents caused by two major factors: - Bad or dangerous infrastructure. - Human causes. Research suggests that twenty five percents of crashes are distraction-related. Social and economic costs for these crashes approach an estimated $40 billion annually

Project definition The purpose of the project is to establish a system, which helps the driver and bring to his conscious the traffic signs. The system will acquire the vehicle positioning and path information while moving The system will compare the vehicle information with required behavior profile in real time. The system will alert the driver of dangerous driving and of violating a “sign profile”.

Infrastructure The system ought to be based on common worldwide infrastructure in terms of : - distribution - availability - cost The GPS is radio based, satellite navigation system that enables users to accurately determine 3- dimensional position, velocity, and time worldwide. The GSM is a wireless communication technology via cellular network.

summary and conclusions System performanceSystem performance - The system is a Real time system and alert - The system is a Real time system and alert the driver of violating a “sign profile”. the driver of violating a “sign profile”. - The system can response to SMS messages. - The system can response to SMS messages. and report it’s positioning through SMS. and report it’s positioning through SMS. - The system includes a built in Simulator - The system includes a built in Simulator and allows implement tests indoors. and allows implement tests indoors.

Conclusion and problems -The GPS data output rate is 1P/sec. -The GPS location accuracy is 5-25m - The searching algorithm in the database is sequential and not the most efficient (As was defined at this project).

Suggestions for future projects -The system will be more efficient using an enhanced GPS unit. -More efficiency will be achieved by a professional database and searching algorithm. -Use of digital maps will match the positioning of the vehicle to the road it’s traveling.
