IBI Group Accessibility Score

Contact Info


This extension computes a numeric accessibility score between 0 and 1 and adds it to the itinerary and its legs.

Note: the information to calculate this score are all available to the frontend, however calculating them on the backend makes life a little easier and changes are automatically applied to all frontends.

To enable the feature add the following to router-config.json:

// router-config.json
  "routingDefaults": {
    "itineraryFilters": {
      // add IBI accessibility score between 0 and 1
      "accessibilityScore": true

The score is only computed when you search for wheelchair-accessible routes.
