London underground redesign

Project Overview

London Underground, aka the Tube, is an underground transport network operating 272 different stations, transporting up to 5 million people per day with up to 543 trains running at peak times. It is often impacted by delays and signal failures causing duress to thousands of customers simultaneously.

The company needs to redesign their products to make them more accessible and reliable, so travellers can travel smoothly, adapt to disruptions better and navigate efficiently via their busy and complex network.

The Problem

Travellers are impacted by delays and signal failures causing duress to thousands of customers simultaneously as they travel. Lack of accessibility and capacity to cater for those who have visual and mobility impairments.

Solution / Project Summary

To improve the current London Underground products & create a more versatile travel experience which will enable travellers to adapt to regular uncertainty, disruptions & efficiently plan fast journeys.

Design process

Understanding The User

To gain a deep understanding of the problems users were facing in the underground, over 3 months I conducted in-depth face-to-face user research, observing thousands of daily users as well as talking to and conducting open interviews with hundreds of users. I wanted to discover the priority needs of travellers, their biggest frustrations and the largest pain points which impacted their travelling experiences.

• Open ended user interviews

• Field Observations

• Customer feedback Reports

• Usability testing

User Research: Pain points

• No connection in the underground, so users are unable to plan their journey once they have already entered the underground.

• Train cancellations and delays, customers panicking and running into stations trying to get on trains, but service is shut off with no alternatives.

• Signage & update boards giving incorrect info due to service interruptions confusing customers.

• Customers with impairments are frustrated by getting held up waiting for station assistance.

• Poor physical signage confuses customers and causes them to travel in the wrong directions.

• Customers don’t know how to use underground apps such as TFL Go. (No Onboarding)

• Customers are confused about touching in and out when changing on interlink lines.

• Customers buy tickets for incorrect zones because they do not understand travel rules properly. I.e they bought 2-3 when they need 1-3.

• Swans!!

User Research: Summary

After talking to over a hundred travellers, observing over 50 customers using the TFL website, TFL Go app and ticket machines, carrying out tasks such as planning journeys looking for alternative routes as well as planning how to receive station assistance. I got to see first hand how travellers interacted with the primary underground planning provider, the TFL go app.

I identified which alternative services were frequently used and what benefits they have and was able to watch their frustration’s during use, identifying shortfalls of each service provider. This enabled me to spot opportunities for improvement and a chance to improve the London Underground experience by providing solutions to their pain points.

I discovered users need to be able to plan journeys without a network connection. Users need more autonomy on routes and want to decide on which line to take with accurate journey times. Users need better app onboarding and need to be able to check why delayed services are not matching up with service board timers, enabling them to make more informed decisions. Furthermore, better communication of travellers with impairments and special needs to London Underground workers enables proper preparations.

Understanding Business Needs

London Underground & TFL’s business goals aim to increase efficiency and productivity of the network. As London’s population and economy grows, transport services must improve, ensuring safety and reliability. The aim is to grow passenger demand, creating greater revenues and financial sustainability which can be used to reinvest in further expansion and maintenance of the network as well as reducing emissions to mitigate the climate emergency and clean up London’s air.

Additionally, after consulting with a member of TFL’s technology team, I also learnt a major technology goal was to start integrating all TFL and London Underground services into one product. It was important for me to understand and integrate these technology and business goals as well as users’ needs in the ideation process and ensure they influenced the design solutions I came up with.

Competitive Analysis

I conducted a competitive analysis, analysing direct and indirect London Underground journey planners to discover what the apps were doing well as-well as identifying shortfalls which were contributing to travellers frustration. I compared a couple of the most important features needed for effective travel planning and noted unique features which could be drawn on later in the ideation process.

Personas and User Journeys

Using results gathered from user interviews enabled me to understand pain points and create personas focused on whom the typical user. This enabled me to stay on track during the design process to address needs and solve the users’ problems.

Problem Statement

After combining and understanding the needs of user goals and frustrations through research. I synthesised the data and formed a problem statement; I used this as a guide and reference point during the brainstorming and idea generating phase to aid with my app redesign.

“The London Underground traveller needs accessible and responsive travel solutions on the go due to regular disruptions, cancellations and service delays as they often find themselves stuck or travelling inefficiently once a problem starts due to poor connectivity options below ground”

Information Architecture

To identify where the redesign would be most effective, I built out the information architecture to understand the structure and further see how users would navigate step by step through London Underground’s official journey planning app.

Paper Wireframes

Paper wireframes were used to rapidly explore multiple design variations for the various digital screens. I was able to reorganise features using feedback gathered to generate iterations that could be later incorporated into higher fidelity screens to provide a better experience and tackle travellers’ needs better.

Mid Fidelity Wireframes

I then moved to mid-fidelity wireframes so I could see how to implement suggested features into the existing flow and design system, aiming to identify key opportunities and experiment on a realistic model without spending too much time on a finished product with colours, icons and pictures.
