Samenvatting
Evaluation is performed on different stages during project planning and implementation. These guidelines advise to start off the evaluation processby stating the type of evaluation to be performed. "initial evaluation", "ex ante" evaluation and "ex post" evaluation are distinguished and each of them has different focus and requirements. By identifying and classifying the ITS-measure to be evaluated these guidelines give advice of the mostlikely main effects of the measure and offer suggestions on indicators and methods to measure and / or calculate the effects. Finally, the guidelines will offer methods to assemble and present the different effects. For the covering abstract see E134653.
