Mobility Personal devices People, goods and equipments (namely vehicles) are entities which move or are moved Mobile or personal devices are a becoming an ubiquitous way of identification and communication Examples: smart cards, RFID tags, information channels on mobile phones Oct 2008 Alberto R. Cunha 3
Mobility Embedded systems Embedded systems are electronic systems included in other (larger) systems Automotive Safety, security, energy management, comfort Examples: Engine management, ABS, stability control, parking sensors, navigation, on-board entertainment (audio/video), driver monitoring Oct 2008 Alberto R. Cunha 4
Mobility Intelligent Transport Systems (ITS) Command, control and monitoring systems covering a wide-area, an infrastructure, or an organisation Early warning and response to incidents Operations management Examples: Fleet management (automatic vehicle location), dynamic signals, real-time driver/ passenger information systems, tolling Oct 2008 Alberto R. Cunha 5
IT trends Computing power is closely related with the evolution of microelectronics technologies Active devices on a circuit increase 55% per year Memory capacity doubles each 1,5 to 2 years Communications bandwidth On local area networks increased an order of magnitude in 5 years These are steady trends from the 1970s to the foreseable future Embedded intelligence is here to stay Oct 2008 Alberto R. Cunha 6

Vehicle identification There are several techniques to identify vehicles, requiring different levels of vehicle and roadside equipments: With pre-defined channels RF antennas and identifiers (DSRC) Via Verde With open control points Image processing London Congestion Charging Open space Satellite-based location and mobile communications Fleet management systems Oct 2008 Alberto R. Cunha 11
Vehicle identification ID channels Dedicated Non dedicated Open Radio-frequency Image recognition Satellite based location Onboard equipament Identifier - Identifier and mobile communications Detection Explicit Non explicit Non explicit Detection complexity Small Large Large Application flexibility Reduced Reasonable: License plates Infractions Reasonable: Navigation Tracking Example Via Verde London Congestion Charging Fleet management stystems Virtual tolling Oct 2008 Alberto R. Cunha 12
