What is Mobility Stuttgart?

Mobility Stuttgart is a mobility app designed to provide users with convenient and efficient ways to move around or navigate within the Stuttgart area.

What is unique about Mobility Stuttgart?

Mobility Stuttgart can combine different modes of transportation and send real time notifications when a route is affected. Commuters can use Park and Ride and even buy tickets. In some selected regions, users can even request for a connecting train to wait in case the previous connection is late.

My contribution – features I worked on

As a UX/UI designer I worked closely with Product, Engineering, Research and Analytics to define and refine features of the app. I added numerous new functionalities to the app and validated them through user testing.

My focus was the search flow area. Below are just some examples of the things that I worked on.

Via functionality

When a users are traveling from A to B sometimes they need to stop in-between for different reasons. By gathering user feedback I understood the need for this new functionality that we called “Via Station”. I explored different solutions, then validated all through unmoderated user testing in Userlytics. Implementation was the last step in this process.

Park & Ride

To encourage users to travel by public transport together with Product we decided to implement Park & Ride (P+R). We had quite a few data points of information, but the challenge was to make this all accessible to the user in an easy way.

Station departures filter

Public transport stations can have multiple modalities. Sometimes it is quite hard for a user to find relevant information about the next departure for a specific modality. In order to make it simple I developed and validated a concept that allows uses to easily find the departure they are looking for. I validated all through user testing and followed up with implementation.

Route summary

While preparing for a trip, users need to have up to date information. Information can include regular trip details or sometimes disruptions. All this can be overwhelming when displayed all at once. To make it all simple while having access to all this information I developed a concept and a set of rules so that the user is informed about the most relevant things, every moment.

Screen flows

Screen flows are an important part of any UX process. I developed detailed flows to showcase the normal “happy path” as well as all edge cases and empty states.

Design vision prototype

To showcase the vision of the app internally and externally I built a fully functional prototype (in ProtoPie). This allowed the design team to get stakeholder buy-in and for the company to attract possible clients by showcasing the Northstar vision in diverse trade shows. This fully functional prototype was even used attract talent during the recruiting process.

The app

Mobility Stuttgart is now available in App Store and Play Store for anyone to try. Here are some of the main screens the app.
