Strategic transport & land-use models

New routes, improving highways, building stations and changing fares are all examples of potential investments in transport.

But with limited financial resources and a variety of potential options, how can we tell which transport improvements are the best to invest in?

Transport models are a source of help and guidance when making predictions about the impact of each potential transport scheme on people's travel decisions. They will also help us predict the impact that these decisions have on congestion and crowding as London's population and workforce continues to grow and change.

The brochure below describes the suite of strategic transport and land-use models owned, operated and made available by TfL Planning. 

The London Land-use and Transport Interaction Model (LonLUTI)

LonLUTI is a model which predicts the use of land for different human activities depending on government policies and transport investment.

The London Transportation Studies Model (LTS)

LTS is a model which uses population and employment forecasts and other inputs to predict the number of trips to be made in London in the future, where people travel to and from and which transport mode they use.

London's Highway Assignment Models

The HAMs are five models covering the whole of London which predict the routes that drivers choose and the associated congestion and delay impacts on London's roads.

London's Public Transport Assignment Model (Railplan)

Railplan is a public transport model that predicts the public transport mode (for example, rail, Tube, bus) and route that a person chooses to get to their destination, as well as the associated crowding impacts.
