Conventional road safety management involves identifying high-risk locations based on previous crashes. In contrast, the Safe System actively assesses all road safety risks so that actions can be taken to reduce the number of crashes and their severity.
The table below shows the differences between conventional and Safe System approaches to thinking about and improving road safety.
Questions |
Conventional |
Safe System |
What's the problem? |
Crashes |
Fatalities and serious injuries |
What causes the problem? |
Mainly poor road user performance. Speeding, drink driving, inattention, deliberate risk taking |
System failures |
Who's ultimately responsible? |
Individual road users |
System designers and operators |
What's the major planning approach? |
Incremental approach to reduce the problem with an associated residual crash problem |
A systematic approach to build a safe road system and minimise harm |
What's the appropriate goal? |
Optimum number of fatalities and serious injuries based on compelling objectives |
Towards the near elimination of deaths and serious injuries |
What's the trade-off? |
A balance between mobility and safety |
Maximising safe mobility |
How's the effort coordinated? |
Incremental gain within individual pillars (roads / speeds / vehicles / people) |
Optimise solutions across pillars (roads / speeds/ vehicles / people) - pillars compensate for each other where performance is poor |
What are the cultural manifestations? |
Legal liability avoidance and risk aversion |
Risk assessment, innovation, trials and demonstrations |
Context of tools in use |
Bias towards pre-existing crash history, understanding crash causes and likelihood, optimising the network for motor vehicles |
Risk analysis based on network design attributes supplemented by crash data, understanding crash consequence, optimising the network for all road users and human frailty |
