3. Road safety 1,600 people die on Australian roads each year (7.86 per 100,000). annual economic cost of road crashes in Australia at $18 billion in 2005. (ATC 2006) The Australian National Road Safety Strategy aims to achieve a reduction in the fatality rate of 40%, from 9.3 per 100 000 population in 1999 to no more than 5.6 in 2010 (56 per million).

30. CAM & DENM Cooperative Awareness Message –100 ms Decentralized Environmental Notification Message –When required (triggered by an event)

31. CAM Profile: basicVehicle mandatory vehicleType, vehicleSpeed, vehicleSpeedConfidence, heading, headingConfidence, stationLength, stationWidth, yawRate, yawRateConfidence, longAcceleration, posConfidenceEllipse, exteriorLights, accelerationControl

32. DENM Decentralized Environmental Notification Messages (DENMs) are mainly used by the Cooperative Road Hazard Warning (RHW) The general processing procedure of a RHW is: –Upon detection of an event that corresponds to a RHW use case, the ITS station immediately broadcasts a DENM to other ITS stations located inside a geographical area and which are concerned by the event. –The transmission of a DENM is repeated with a certain frequency. –This DENM broadcasting persists as long as the event is present.

33. DENM Triggering condition Hard breaking of a vehicle e-Call triggering Traffic jam detection Detection of a vehicle violating a signal Detection of a turning collision risk by a roadside ITS station Detection of a slippery road condition (ESP activation) Detection of a low visibility condition (activation of some lights or antifog)
