@shmpwk It seems that I don't have the accessibility to assign a label or a reviewer. Can you help me ?

Great work! I will leave minor comment.

@Ericpotato
Please check spell check CI.

As for signalized crosswalk, when the traffic light for the car is green and there is a pedestrian on the crosswalk which intersects with the planned route, the ego will drive without slowing down because of the crosswalk traffic light estimator.
Could you check the ego behavior again for the signalized crosswalk?

@Ericpotato
Could you modify the pull request title?

[shmpwk]

I'd like to reuse this PR for the future.

I'll update the images with the new rviz ui and test the instructions myself.

@Ericpotato and @shmpwk please check https://autowarefoundation.github.io/autoware-documentation/pr-514/demos/planning-simulation/#driving-through-a-crosswalk should be pretty much ready to merge now. Performed the tests multiple times.

@shmpwk the Experiment 2 at Signalized crosswalk was different than the older experiment.

The ego vehicle only has red light behavior after waiting for a while at the red light even if there is a pedestrian.

I have reflected the actual behavior in the demo guide.

Please review as soon as possible 🙇

In the future I will consider separating these mini-demos into some other section, separating them page by page. But for now let's focus on other priorities.

Thank you so much for your help!
I confirmed the demonstration worked.
