Systematic evaluation is important for justifying proposed investment in Intelligent Transport Systems and for determining priorities. Evaluation is also important for checking the on-going cost-effectiveness of existing systems.

IBEC_logoThrough the ATLANTIC project, Ankerbold played an important role in the formation and early development of the International Benefits, Evaluation and Cost working group of experts in ITS known as IBEC.

Ex-ante evaluation

In developing the ITS strategy and policy framework, it is advisable to establish today’s situation as a quantified baseline for future evaluation.

Evaluation is never simply a matter of “justifying” the investment. ITS must be a response to a need, not something we want in order to keep up with trends. ITS will be one of the possible responses, alone or in combination with other measures and policies.

Post-hoc monitoring and analysis

After an ITS project or plan has been implemented, monitoring and evaluation are essential to improve performance in the future. Does the solution meet its objectives? Are the outcomes as intended?

Monitoring can identify the range of benefits achieved and these can be quantified with data from the internal monitoring. Careful monitoring of costs can enable the operation and maintenance costs for the specific service to be identified and separated from wider organisational costs.
