Outline1) Driving Problems2) Objective3) System Flow4) Model Demonstration5) Advantages6) Further Development
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
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

Objective:
Provide drivers with:General Traffic Information1) Speed Limit2) Road Sign3) Location4) Traffic light status5) Weather condition6) Map of surrounding streets
Emergency Traffic Warning:
1) Accidents2) Traffic Jam3) Road blockage4) Poor Weather Condition5) Lanslides6) Letting way to emergency vehicles
Further Development:
1) Windscreen projection2) Integration with dashboard and console3) A central system controlled by a company or government4) Optical fibres for better transmittion5) 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.
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.
Disadvantages of GPS- Subject to movement or destruction by environment factors.- Limited precision.- Complicated.- Limited Coverage.- Easily blocked by tall buildings.
