New mobility projects can impact many areas, including accessibility, equity, safety, liveability, health, the environment and public budgets. Neglecting any of these can lead to unsustainable planning. An assessment prior to implementation helps you select appropriate and cost-effective mobility measures, and gives you an idea whether the measures will bring the intended results. TIDE has developed a straightforward tool for determining the impacts of new transport measures. In this course, you can use the tool to assess measures from your own local context.
