Main Roads have completed a preliminary investigation form and concluded that there are no road environmental issues that may have contributed to the causation or severity of the crash. Issues The crash data reveals a pattern of losing control along the Galbraith Road. Whether this is due to speed, inattention or being under the influence, it is difficult to tell with the current data however an 85 th percentile in excess of the legal speed limit does indicate that some sort of traffic management should be employed. Good traffic management investigates all options including vertical displacement measures like speed humps and horizontal displacement devices like chicanes or oval medians to ensure that the desired reduction is achieved. Design Constraints 1. With the presence of a school on this street, any traffic management method employed will have to cater for the movement of buses 2. Galbraith is a local collector so two way travel has to be maintained at all times 3. Location of crossovers – In order to reduce inconvenience to residents, it is advisable to locate traffic management between crossovers 4. Lighting – Australian Standards state that lighting must be adequately lit. In order to reduce the cost of the installation, it is advisable to locate traffic management close to existing lighting 5. Available Road Reserve width Page 66
