Key messages from online survey Can you make a difference to road safety? If so, how? 63% of respondents believed that they could do something to make a difference to road safety. The majority said that improving their decision making, being more courteous and encouraging others to do the same could help to make our roads safer. Do you with the Safe System principles? What is the biggest threat to achieving a Safe System? The large majority of respondents agreed with the Safe System principles, and believed that driver behaviour and driving at excessive speeds for the conditions were factors which could cause a problem within the System. What is the biggest thing that can be done to improve road safety? The majority of respondents believed that focusing on education and driver training is critical to improving road safety. Increased police presence on our roads and better road maintenance were also frequent responses. 20
and benefits? Accurately modelling the effects of introducing widespread, large scale infrastructure treatments is extremely difficult. Table 1 however summarises the potential benefits and costs of different infrastructure treatments. It also provides a guide as to where treatments might be applied on the network: Countermeasure Expected Benefit Expected Cost Where 2+1 configuration $$$ Highest volume, strategically important roads Centreline barrier $$$ Highest volume, freight and regional access routes Highest volume, freight and regional Wide centreline Sealed shoulders Audio tactile line marking $ access routes where centreline barrier not feasible Highest volume, trunk, freight and regional access routes where above treatments not possible Highest volume, trunk, freight and regional access routes where above treatments not possible separation* $$$ Highest volume, trunk, freight and regional access routes Highest volume, freight and regional access routes Roundabouts* Discrete sites if warranted on lower order roads No turn* $ Where viable turn lanes* $ Entire network Plateaus* $ Highest volume, trunk, freight and regional access routes Any road in a built up area if warranted * Intersection treatments Table 1 Effectiveness and cost of Safe System infrastructure treatments in reducing

When feasible Unknown but outcomes are best when centreline barrier or wide centreline are in place Not modelled but expected to be high Provide safe corridors as viable alternatives for cyclists When feasible Unknown Unknown Install raised platforms at dedicated pedestrian crossing facilities When feasible Not modelled but expected to be high if speeds are well managed Unknown and serious casualty savings for infrastructure treatments are based on application on all trunk roads and all initiatives being implemented in 2017. This scenario is unrealistic but it provides scenario to compare the cost and benefits of treatment options on a broad basis. 45
Safe Speeds Considered by CASR When should it be implemented Serious casualty savings 2017-2026 Cost Key Reducing all 110km/h speed limit to 100km/h. Reducing 100km/h speed limits on minor road categories to 90km/h (i.e. feeder roads, other roads, and no- state controlled roads). Reducing all 60km/h to 50km/h. Year 1 205 (if implemented in 2017) Less than $1 million for each speed change. Other Implement speed limits on specific road corridors or in certain geographical areas rather than over the whole state. - Not modelled but any reductions in travelling that can be achieved are considered worthwhile. Unknown but expected to be low Reduce speed limits in high- activity areas with numerous road user types to 40km/h. - Not modelled but any reductions in travelling speed that can be achieved are considered worthwhile. Unknown but expected to be low 46
