Ongoing monitoring and evaluation of a road safety strategy is required to:
- ensure that the road safety strategy actions are being carried out and assess the degree to which actions have been completed (progress made) and targets met
- determine how actions are being carried out and whether this process needs improvement or changing (process evaluation)
- determine if there are casualty and crash reductions, and/or behaviour changes (outcome evaluation) from the actions undertaken
- determine the impact on public acceptance, political environment, support of key stakeholders, remaining funds (cost effectiveness) etc., if required.
Monitoring and evaluation is an essential source of information which helps the lead agency ensure that goals are being met, and may assist other agencies in ensuring they are contributing effectively. Monitoring and evaluation are critical if continuation of the strategy is contingent upon the demonstration of ongoing benefits.
