In this section you specify parameters which will define the location and level of detail of your appraisal.
Based on your inputs here, and throughout the application, health impacts will be estimated by comparing the situation "without intervention" with the situation "with intervention".
Throughout the tool, you will provide inputs for the situation "without intervention" on the left, and "with intervention" on the right.
By default, the tool shows "basic" options. You can choose to show "advanced" options in the panel to the right.
In the basic workflow you provide information on the "volume of active travel", in the format available to you (mode users, or trips). You can think of this volume as the product of users x trips x trip length. The tool will complement your inputs with missing information required to calculate this volume. You can review and change the additional parameters used in the "Assumptions" card. Health impacts are calculated as the difference between the situation with and without intervention. In the advanced workflow you can refine which subjects and trips are used for these calculations.
The tool suggests starting values based on the entire population in the selected area (LAD). These values are meant as rough guidance. Your intervention may affect considerably fewer people or trips; edit input fields directly, or use adjustment features where available.
You can find a detailed User Guide by clicking on the "?" icon in the top right.
