Help provide London with better public transport using modelling

London is a world-class city that’s home to 8.6 million people and visited every year millions more. Keeping it working, moving and growing is a huge challenge, but one that TfL rises to every day. Transport Modelling team within Public Transport Service Planning drives the development of Bus, Underground, DLR, Elizabeth line, Trams, London Overground and National Rail services in London. We help ensure TfL’s plans support London’s growth and meet the objectives laid out in the Mayor’s Transport Strategy.   To deliver a transport system that meets these objectives, TfL is committed to investing millions of pounds in upgrading its train and stations infrastructure as well as optimising its services across the network. Transport Modelling plays a part in our success, by optimising customer priorities including journey times for nearly 9 million public transport trips per day in London.

Your challenge will be to lead your team of transport modellers as you provide analysis and insight to enable senior business leaders resolve complex strategic and operational problems with our services and stations. Owning and maintaining a suite of models that are up to date, validated, calibrated and fit for purpose. You’ll use these to provide modelling that is technically proficient, understandable and actionable, and influences business and operational decisions while ensuring our customers are at the heart of that decision making. We’ll also expect you to develop new and innovative approaches to improve the quality and efficiency of modelling, and analysis to provide results for strategy and service development decisions.

One of the key early responsibilities of this role is to deliver the next major update of the underlying database used to calculated LCH values. Lost Customer Hours (LCH) is fundamental metric used throughout London Underground to support such investment decisions and monitor the performance of the operational railway.  The measure ensures key business and operating decisions are taken considering the impact on the customer.
