Abstract

Rural communities are overrepresented in the Australian crash statistics with 66% of the Australian road fatalities occurring on rural roads despite only 33% of the road fleet using rural roads frequently. Australian literature on traffic calming is dated and provides information predominantly for the urban road environment and does not direct road designers to modern engineering means. In the past decade a number of traffic calming devices have been implemented into the urban road network and this has been represented by a significant reduction in the number of fatalities. However, these have not been incorporated into rural communities due to a perceived unbeneficial cost by use ratio.

The report aims to analyse 14 sites and compare before and after traffic calming installation crash data to determine if traffic calming provides significant improvements to the safety of the road network. The report will also analyse the speed of drivers using these traffic‐ calming devices to quantify how driver behaviour in moderated at each site. To achieve this each site will be investigated and the speed of drivers recorded over a given distance before and after the traffic‐calming device. This will provide a map of driver behaviour and interactions through the rural community. This behavioural analysis will be instrumental in viewing the operational efficiency of traffic calming devices and recommending where the optimum positioning of a device would be for maximum benefit. A Z‐test will be performed on the data to determine if the speed variations are statistically significant or a result of statistical deviation.

The report finds that traffic calming provides varying degrees of benefit depending on each individual road environment. It quantifies the predicted area of influence of each traffic‐ calming device and provides advice as to appropriate scenarios to provide the predicted maximum safety benefit.
