Abstract
The current standards associated with lighting road and streets in Australia give no guidance to the incorporation of dimming into lighting schemes. It is hypothesised that
by dimming road lighting during times when few people are using the road there will be little effect on the safety of the roads during these times. Implementing a dimming
scheme could maintain the level of safety required at night when traffic volumes are high and could save electricity when the high standard of lighting is not required. One of the two main objectives is to investigate whether crashes and traffic volumes follow the same temporal trends, justifying the basis behind this project. The second objective is to determine if a dimming scheme could be cost effective in the long term if the social cost of crashes and social cost of carbon is considered. This is done by identifying three exemplar sites for review, creating three different treatments of applying dimming, redesigning the sites using these dimming treatments then comparing the costs associated with each site and dimming treatment to determine the most cost effective solution. The main outcome of this project is that, in the current social and economic environment, dimming is not the most effective method in reducing the costs associated with road
lighting.
