The Transport for London website team's dedication to user centred design has helped make their site a leader in the public sector.

A recent report from the Public Accounts Committee has been critical of the way that UK government websites are designed and managed. But TfL.gov.uk, the Transport for London website, was one of the few cited for good practice and performance. It's no real surprise: the TfL team really understand the value of listening to customers, and designing for their needs.

Sometimes, we're pleased to say, TfL hire Flow to help them.

What London travellers really need

TFL's flagship offering is Journey Planner. Back in 2006, we helped TFL research and design the mobile travel alerts element of the service. Designing personalisation features for a website is never easy - because most of the time, people don't want to personalise. We all just want the website to do what we need with minimal effort.

Flow ran experience labs: one-to-one sessions with a range of different people. The lab sessions focussed on digging out the reality of London travellers' needs, motivations and behaviours.

A key technique was retrospective accounts: we gathered detailed stories about what people really did in specific situations. So rather than asking "what do you think about travel in London" we asked things like "Tell me how you got to this interview today," and "tell me about the last time something went wrong with your commute to work." To keep the conversation fun and manageable, we also collaborated with the respondents to create pictures, lists and timelines using sticky notes and marker pens.

Once we understood user needs, we could identify a service that people would really like. The travel alerts system lets you identify the routes you are interested in (typically the ones you commute on every day), and get travel alerts for those routes at specific times. We defined the concept, worked with TFL to create wireframes, then fine tuned them with two iterations of usability testing.

TfL personalised travel alerts: Prototype and live site.

Practical commitment to customers

Since then we've helped TfL research and optimise all sorts of things from the Oyster Fastload process to the London Transport museum website. And since communicating with travellers is a multichannel activity we've even run iterative usability testing in London Underground stations - quite a challenge.

Now approaching...

Flow is now working with TfL on a strategic project to map out the future for the website, and we're basing the process on user research.

To improve on the experience labs methodology, we're asking our research subjects to fill in diaries. We're catching reports of travel experiences while people are travelling, then following up on the details in the lab afterwards. From there we'll be using a scenario-based approach to map out what people's travel experience and identify the TfL website's optimal role.

The finished site will offer London's travellers an even more useful, usable and appealing travel experience.
