Abstract:
Excessive speed is currently
one of the major contributors to road trauma in Victoria. Speed
is an important contributor to crash causation, and moreover, speed
is the critical factor in injury severity. While countermeasures
such as speed cameras and improved traffic engineering are having
a positive effect in reducing the role of excessive speed in road
trauma, it is likely that the development of new technologies to
further enhance speed compliance will have significant road safety
benefits. The purpose of this project is to assess the potential
of new technologies related to speed limit compliance, and to put
forward a brief protocol for implementing and evaluating new technologies
for enhancing speed compliance. Speed Indictor Displays have been
found to reduce average speeds in Europe by 4-8 km/h, which translates
to significant reductions in crash severity. A proposed trial of
Speed Indictor Displays is described for specific highway routes
in Victoria. The well-established relationship between speed and
injury severity was used to estimate the benefits associated not
only with a reduction in average speed but also associated with
the implementation of Speed Indicator Displays along these routes.
Cost-benefit analyses clearly show the safety benefits associated
with the use of Speed Indictor Displays at all three sites for both
4 km/h and 8 km/h reductions in average vehicle speed.
