Here are random bits of information about how we are going about developing our solution.
We are using a user-centered design process to tackle this problem. This methodology calls for an extensive understanding of the people involved in this project (i.e. stakeholders: the transit authorities, the operators of the vehicles, the commuters and the non commuters) and the activites they perform. Our goal is to inform the design of our solution with the real needs of the stakeholders.
To better facilitate communication between team members, we have setup a Wiki to act as an evolving digital collection of our ideas and resources that are pertinent to the solving the problem. On the Wiki you will find our meeting notes, websites with information related to the problem and other tidbits that should give you an idea the team's current state of mind.
Apart from the Wiki, we have setup an email address for the group which can be used contact all the members of the group. In addition, we have setup and shared a calendar (via Google Calendar) to keep us abreast with events and deadlines related to the project.
The website serves as a more refined presentation, as compared to the Wiki, of our current status in solving the problem. As our solution generally revolves around providing an interactive option for navigating a public transit system, we decided to provide a more interactive way of viewing the timeline of our progress. Give it a shot.
