The study utilises data from Event Data Recorders (EDRs) obtained from the Victoria Police's Collision Reconstruction and Mechanical Investigation Unit (CRMIU). The primary focus is on understanding the speeding profiles of the 165 bullet vehicles and 147 free-speed vehicles within the 271 EDR-equipped vehicle dataset. The analysis includes eighteen driver, vehicle, and crash characteristics, and employs chi-square tests to identify statistically significant associations with speeding. While the findings highlight the prevalence of speeding in both bullet vehicles (63%) and free-speed vehicles (71%), caution is advised when generalising this result due to a potential sample bias towards speeding. Statistically significant associations with speeding were found for driver age, driver alcohol, driver drug results, crash time and day, crash area, crash intersection type, crash speed zone, and crash type. A comparison was also undertaken with four other studies: two focused on crashed vehicles, one focused on self-reported speeding, and another on vehicle travel speeds throughout Victoria. The report concludes by emphasising the need for targeted interventions focused on younger drivers, those under the influence of alcohol or illicit drugs, drivers travelling at nighttime or in metropolitan Melbourne, T-junction intersections, and traffic within 40 to 80 km/h speed zones. | | Report Number | CASR238 | | Publisher | Centre for Automotive Safety Research | | Publisher City | Adelaide | | Sponsor | This research was funded under a project agreement with the Transport Accident Commission (TAC) | | ISBN | 978-1-925971-71-2 | | ISSN | 1449-2237 | | Page Count | 46 |
