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
