Review of the key messages and resources of this course
1. Summing up
We hope you've found this TIDE course on conducting an impact assessment useful and that we have provided you with some interesting ideas and examples, as well as the opportunity to learn from and with your colleagues across Europe.
In addition to the steps of the TIDE impact assessment (pictured on the right), some of the key points we hope you'll take away:
- Impact assessment plays an important role in supporting decisions regarding the selection and design of optimum urban transport projects or measures.
- Assessments should be holistic. This requires all of a measure’s positive or negative impacts to be assessed in terms of the triple bottom line (economic, social and environmental) to avoid unforeseen problems and trade-offs later on.
- Existing assessment methods, such as Cost-Benefit Analysis (CBA) and Multi-Criteria Analysis (MCA), have strengths and weaknesses which limit their application to urban transport measures. Especially for small-scale or ‘soft’ measures, the assessment must be simple and include a wide range of qualitative effects.
- The TIDE impact assessment method is a simplified option with which to compare different measures’ performance, taking quantitative and qualitative effects into consideration. An additional economic assessment can be integrated if necessary, and if data availability allows doing so.
- The availability of simplified approaches, such as the TIDE impact assessment method, may open the door to assessment of measures not normally assessed to date.
