On-road speeds just before the default limit was introduced were compared with speeds a year later. The numbers of casualty crashes and casualties in the year before the default limit was introduced were compared with the corresponding numbers in the first year that the default limit was in effect. On roads where the speed limit was reduced from 60 km/h to 50 km/h, average vehicle speeds decreased by 2.3 km/h and casualties by 24 per cent. On roads where the speed limit remained at 60 km/h, average vehicle speeds decreased by 0.9 km/h and casualties by 7 per cent. | | Report Number | CASR005 | | Publisher | Centre for Automotive Safety Research | | Publisher City | Adelaide | | Sponsor | Department for Transport and Urban Planning (SA) | | ISBN | 1920947043 | | ISSN | 1449-2237 | | Page Count | 37 |
