Scooter_rental mode return the same speed as bike_rental mode

[Chu-c-git]

The scooter_rental and bike_rental modes in OpenTripPlanner (OTP) are expected to have independent parameters according to the documentation. However, both modes currently rely on the "bicycle" mode settings in router-config.json, causing the speed configurations to be identical.

Expected behavior

According to document, there are different params for scooter_rental and bike_rental mode in "router_config.json" . The speed of different mode should be difference.

Document sample: https://docs.opentripplanner.org/en/latest/RouteRequest/#config-example

Observed behavior

Both scooter_rental mode and bike_rental mode depends on "bicycle" mode settings.

Steps to reproduce the problem

[optionsome]

I tested this and seems like you are correct. I can look into this more tomorrow to see what is the cause and to see if it affects other scooter preferences as well.

I have a feeling that there might be three separate(?) problems:

1. With the Transmodel API, that the debug client uses, I think the bicycle preferences might replace the scooter preferences because it's not possible to set scooter preferences through the API.
2. There seems to be some problem with egress routing with GTFS API as well that the bicycle speed is used instead of the scooter speed
3. There is some sort of a heuristic(?) problem with at least access routing that the bicycle speed changes what results you get even if it doesn't affect the actual speed that is used in results

I'll check next week if it's easy to fix these issues.

[optionsome]

I've fixed 2. and 3. in #6599.

The issue with the Transmodel API can't be fixed as of now since the API lacks scooter preferences and it uses the bicycle preferences to populate the scooter preferences. The bicycle preferences get default values from the router-config which causes the behaviour you have witnessed. If you wan't to use the Transmodel API in production use, just pass in the parameter you want in the request as the bicycle preferences so they will be used for the scooter rental as well.

Thanks for helping with the debugging! Currently, we've set up two separate OTP services to differentiate between bike and scooter speeds as a workaround. However, we're wondering if there's a way to configure different speeds for bike_rental and scooter_rental within a single OTP service. We're trying to simulate a multi-modal transit scenario and would prefer to avoid maintaining two separate instances if possible.
