An exponentiated second order polynomial function was used to model the relative risk of being involved in a casualty crash based on free travelling speed. The relative risk was found to approximately double for each 5 km/h increase in free travelling speed. This curve and the original data were then used to estimate the effects of various hypothetical speed reduction scenarios. Illegal speeding was found to be a major factor in casualty crashes and it was found that even very small reductions in the speeds of vehicles in general could be expected to result in a major reduction in the frequency of casualty crashes in an urban area. | | Report Number | CR207 | | Publisher | Australian Transport Safety Bureau | | Publisher City | Canberra | | Sponsor | Australian Transport Safety Bureau | | ISBN | 0642255865 | | ISSN | 14454467 | | Page Count | 38 | | Notes | http://www.infrastructure.gov.au/roads/safety/publications/2002/pdf/Speed_Risk_3.pdf |
