Road AccidentsRoad 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 AccidentsRoad 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 definitionProject 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.

Conclusion and problemsConclusion 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 projectsSuggestions 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.
