Commissioned by the Department for Transport, this step to step guide as been developed as an aid to the evaluation of transport interventions and as a practical resource to accompany the ‘Guidance for Transport Impact Evaluations’: choosing an evaluation approach to achieve better attribution and building on a key principle in this attribution guidance that most evaluation strategies would be strengthened if some initial logic mapping of a programme or project being evaluated were undertaken.

The methods used in this guide were the Logic Mapping and the theory of change evaluation.

The guide aimed to enable people involved in evaluation of transportation to improve self evaluation skills, promoting accountability.
