# Module map_model::objects::modal_filter

source · ## Structs§

- A diagonal filter exists in an intersection. It’s defined by two roads (the order is arbitrary). When all of the intersection’s roads are sorted in clockwise order, this pair of roads splits the ordering into two groups. Turns in each group are still possible, but not across groups.
- A filter placed somewhere along a road

## Enums§

- The type of a modal filter. Most of these don’t have semantics yet; the variation is just for visual representation
