Many drivers have met the inconvenience:
1) Condensed traffic Lights
4) Bright Conditions
2) Obstacles to traffic information1) Billboards2) Double Deckers3) Fog4) Trees5) Rain on the wind screen
3) Missing the road signs
Video, government’s website and survey reveals that:
Need a system to provide instant traffic information

To Provide drivers with:
A. General Traffic Information:
1) Speed Limit
2) Road sign
3) Location
4) Traffic light status
5) Weather condition
6) Map of surrounding streets
![Page 8: Hong Kong Student Science Project Competition 2005](https://reader033.vdocument.in/reader033/viewer/2022061602/56814cf8550346895dba0955/html5/thumbnails/8.jpg)
B. Emergent Warning:
1) Accidents
4) Traffic Jam
3) Road blockage
6) Poor Weather Condition
2) Landslides
5) Letting way to emergency vehicles

Advantages:
• Traffic safety promoted
• Knowing traffic condition in advance
• Get information more easily by artificial sound
• Interactive communication between the car and the central server
• Drivers’ privacy protected

Further Development
1) Windscreen projection
2) Integration with dashboard and console
3) A central system controlled by a company or government
4) Integration with GPS

Ways of integration
-In towns where there are a lot of buildings, underground signal emitting system should be used.
- In countryside, GPS should be used.
![Page 24: Hong Kong Student Science Project Competition 2005](https://reader033.vdocument.in/reader033/viewer/2022061602/56814cf8550346895dba0955/html5/thumbnails/24.jpg)
Advantage of GPS over underground signal emitting system
- Low Costs- Need not change the structure of the roads
Disadvantage of GPS- Subject to movement or destruction by environment factors.- Limited precision.- Complicated.- Limited Coverage.- Easily blocked by tall buildings.
