@schnuerle , this does a good job of representing my problem w/ no stopping vs travel. In this model, they represent the same thing.

Love the table, nice work! For the "?" you could use the Emoji White Question Mark or even Wavy Dash to show it's not clearly defined.

In my mind, these activities that are used for defining rules for curb policy, no stopping and travel are different, beyond what the table currently shows, maybe more about physical build. An example "travel" area by the curb could be a flush curb to the travel lane of a road, while a no stopping rule could apply to a curb cut in an area that is never a normal travel lane. I'm not sure of the policy differences and needs between these rule definitions of 'travel' vs 'no stopping' - maybe you just want to be clear that this zone at this time of day is a travel lane and be clear about that, vs just a no stopping area?

I've replaced the question mark w/ the emoji. I think I got the right wavy one. Let me know if I'm off

If you can't stop there and you can't travel there, I'm not sure what you could do there. I can think of one example of such a situation, but it suggests we ought to have a no travel activity instead of a travel one. It also bends the definition of a curb:

A promenade or large sidewalk-like area could have a no travel activity defined for all non-municipal car-like classes and a no parking policy defined for scooters.

It seems that temporary uses that block use of the curb, such parklets for outdoor dining, or a construction lay down area could represent an opportunity to use the proposed no travel activity, as only using no stopping could communicate that the curb lane could still be utilized in some fashion as a travel lane.

Also, local jurisdictions will need to do some translation work to fit local regulatory practices to CDS. As an example, in SF we use no stopping on signage to designate curb space that is temporarily permitted for moving trucks to stop and conduct loading activity.
