One of the groupings of innovations we noticed when we were doing our work was about the importance of software for everything that previous speakers have mentioned, like tracking who is getting on, where they are getting off and those types of things.
I'm not a software expert, but from a technical perspective, setting up data sharing or linking data sharing between different systems is not technically challenging. It's not that there's a specific software. It is technically possible.
The challenge is in data-sharing agreements, particularly when it comes to for-profit companies not wanting to divulge things that they feel may interfere with their profits. It is really important for multimodal transit and to link all of those different systems that they talk to each other. It's not technically challenging; it is getting data-sharing agreements in place and making people play nice, for lack of a better way to say that.
