Design LTN tool improvments: Bus Routes

[andrewphilipsmith]

Current behaviour:

When placing modal filters on, the tool will warn the user if the filters affect existing bus routes and adjust the edits if required (e.g. substituting a modal filter for a bus gate).

When adjusting one-way streets or turn restrictions, no equivalent warning is given if the edit affects extant bus routes.

Example

Video shows current behaviour whilst editing Roosevelt Drive in Oxford

• Add a modal filter - a warning is given about the effect on a bus route.
• Add one-way restrictions that make it impossible to drive along Roosevelt Drive (no warning given)
• Add turn restrictions (no straight ahead) that make it impossible to drive along Roosevelt Drive (no warning given)

Suggested improvement:

When editing one-way streets and turn restrictions within an LTN, the user should be warned if their edits will affect extant bus routes.
