The document discusses a study on amber light running at traffic signals in Australia. It presents data on different categories of light running like immediate amber and delayed amber. It also discusses the road traffic code requirements for stopping at amber lights. Some influential factors on light running like traffic volumes and intersection layout are highlighted. Crash cost data showing higher costs for property damage and fatal crashes is shown. Potential approaches to address light running like enforcement, education and engineering changes are proposed. Results of monitoring light running at different intersections using a combined approach of these methods are presented.
