The ongoing research, now in its 12th year, has done much to reveal how residents and motorists respond to a low urban speed limit. This paper documents further findings in relation to enforcement and crash outcomes as separate issues and some discussion is made on the possible impacts of the new 50 kmlh General Urban Speed Limit (GUSL). A trial with enforcement on 40 kmlh local roads was conducted to determine halo effects in combination with traffic monitoring equipment. Laser gun enforcement was shown to be most effective with an effect lasting up to 10 days from the time of deployment. Speed feedback signs (at enforcement sites) were shown to have no halo effect and lost effectiveness with continued deployment at the same site. In reviewing crash data from before and after the implementation of the 40 km/h scheme, it is concluded that the 40 km/h speed limit has been responsible for a reduction in crashes on local roads given the 60 km/h GUSL operating elsewhere (now 50 km/h). | | ISBN | 0731053958 | | Conference Name | Road Safety Research, Policing and Education Conference | | Conference Abbreviation | RSR | | Conference Location | Sydney, Australia | | Conference Date | 24-26 September 2003 | | Journal Volume (Issue) | 1 | | Page Range | 295-302 | | Page Count | 8 |
