Slide 2
Outline Current Applications of GPS Automated GPS Cars GPS
Assisted Speed Limits Traffic Management and Bus Routes
Slide 3
Current Common Applications Satellite car navigation Route
guidance in vehicles - Simple GPS device - Maps of the road network
- Calculates the best route Accuracy only a few metres -
Disadvantages of errors in dense urban areas - Is not 100% correct
on best route
Slide 4
Driver-less Cars Car control by an onboard computer Requires
centimetre high accuracy GPS Inertia, radar and optical sensors to
detect surroundings Automatic path correction and obstacle
avoidance Teams participate in races run by the Defence Advanced
Research Projects Agency (DARPA)
Slide 5
Driver-less Cars GPS guided cars used for high speed purposes
Only uses predefined GPS route and Inertia sensors Can not detect
obstacles
Slide 6
GPS Speed Limits Technologies Digital speed zone maps GPS
In-car alert or limit systems How it works Cars to recognise speed
limits Measure speed based on GPS Link to in-car systems to alert
or limit speed
Slide 7
Technologies Online Schedule Traffic signal system Roadside
antennae GPS How it works GPS locations and bus schedule determine
priorities Signals sent to activate traffic lights to allow bus
travel through ahead of other vehicles. Bus Priority Systems
Slide 8
Conclusion Future of GPS more than just car navigation High
potential for use for automated cars Currently being trialled for
traffic management Can be used for alerts for increased road
safety
