I want to create a multi-modal network to produce service areas from metro stations using both walking and bikesharing. The idea being that using bikeshare from a metro station will help to increase the service area. Bikeshare stations would act as the transfer junction between walking and bikesharing modes. I’ve tried a few different ways to produce the service areas but don’t think I’m getting the results I am looking for. I created a TravelTime attribute and have a Pedestrian_Street layer which is set to [Meters]*60/3,000 (3 km/hr) and a Bikeshare_Street layer which is set to [Meters]*60/10,000 (10km/hr). The connectivity is set so that the Bikeshare_Street layer is in group 1, the Pedestrian_Street layer is in group 2, and the bikeshare stations connect to groups 1 and 2.
Any advice on what I may be doing wrong or might need to do would be greatly appreciated. Here are some of my questions/concerns:

Any advice on what I may be doing wrong or might need to do would be greatly appreciated. Here are some of my questions/concerns:
- Should I be using a separate bikeshare street network and a walking street network (even though they are the same) or would there be another way to do this? The bikeshare stations are directly connected to the street layers as opposed to using bikeshare "station entrances".
- How can I ensure that the higher travel speed is only considered between bikeshare stations? Further, how can I ensure that bikeshare trips are only counted if they end at another station?
- When running the analysis, if I exclude the Bikeshare_Street layer, then I end up with service areas surrounding the bikeshare stations, which seems counter intuitive as it seems it should only include the pedestrian network.
