The maxim of ‘what gets measured gets done’ is very true.
A carefully selected performance measure and target that is regularly reported provides a very real incentive and results focus.
The success of any transport program can be measured a number of ways, reflecting the diverse perspectives of the different stakeholders.
The primary categories of transport system performance are (1) safety, (2) access and (3) mobility.
These contribute to community outcomes such as health and safety; liveability and a strong economy.
Safety can be measured in terms of public health, to allow comparisons across other health measures. Measures used include serious injuries or fatalities per capita – with agreed definitions of what constitutes a serious injury or a fatality, with targets benchmarked against international best practice.
Access means being able to travel to a desired destination. Access is difficult to measure in a simple way, but can be measured by the number of people within 400 metres of a regular public transport service for example. Mobility can be measured in terms of time or cost to travel, and combined into an index or a level of service.
Mobility is the ability to reach a destination in a time and at a cost that is considered reasonable or acceptable.
Be careful what you select to measure.
