From the Wayfinding Graph of a building, Situm is able to compute three kinds of routes. You may select which type will be computed in the "Routes and Navigation" Settings Menu, by clicking on "Accessibility mode" (see next Figure).

Type #1 - Shortest Route (default)

Unsurprisingly, the "Shortest route" type computes... the route with the shortest total distance from point A to point B. This is the default route type. A thourough description on how this works can be found here.

The following figure shows an example. The user wants to go to the WC using the shortest route. Situm computes it, suggesting that the user should use the starirs. This yields a total route distance of 136 meters.

Type #2 - Only accessible routes

As an alternative, Situm Mapping Tool allows you to retrieve routes that are suited for people with reduced mobility. This will usually be  routes that will avoid elements that are not suited for wheelchairs, such as stairs. You may want to read more on how to accessible routes work, and on how to configure them in the Situm Dashboard.

The following figure shows an example. The user wants to go to the WC using only accessible routes. Contrary to the previous case, Situm in this case suggests a longer route that avoids the stairs (non accessible), using an elevator (accessible) instead. This yields a total route distance of 221 meters.

Type #3 - Only routes with not accessible floor changes

Finally, Situm Mapping Tool allows you to compute routes that do almost the opposite: avoid floor changes that have been marked as "accessible". This was designed with a very specific use case in mind: avoid routes that use elevators, in favor of those that use stairs / scalators. This is very useful not only to promote a healthy lifestyle, but also to avoid the formation of crowds around elevators.
