Transport models are built for a number of reasons, most commonly, to inform appraisal, design and planning decisions which determine the allocation of resources. However, they are also a resource in themselves; they offer a simplified representation that aids our understanding of the world.
Transport Scotland have developed a linked hierarchy of transport models- national and regional models- and a land use model which, applied together, provides a full Land-use and Transport Interaction (LUTI) modelling capability.
The national transport model, Transport Model for Scotland (TMfS) offers a generalised, multi-modal representation of travel demands and infrastructure supply for a base (2012) and future forecast years.
The national land-use model, TELMoS (Transport and Economic Land-use Model of Scotland), provides independent demographic, planning and economic forecasts which form the basis for future travel demands.
There are also a number of regional models associated with LATIS.
Transport Model for Scotland (TMfS)
TMfS is a strategic transport model, which provides a broad representation of transport supply and estimates of transport demand. The current version is TMfS14 which has a base year of 2014.
- covers the whole population of Scotland
- details the choices made by people on how, where, why and when they travel
- links with an interactive land-use model, TELMoS, which provides a land-use transport interaction
- is designed for broad option identification, ranking and scheme/policy appraisal
- does not model the operation of junctions or congestion
- is capable of modelling traveller responses to network wide road tolling/pricing
- has a wide range of model outputs.
The development of the models is underpinned by an extensive bank of transport data.
Reports relating to the National Models can be found in the documents, reports and guidance section.
In 2015, an updated, strategic Transport Model for Scotland was developed, with a base year of 2014.
TMfS14 and TELMoS14, the linked national land use model, form the standard release version of the model.
TMfS14 is the latest version of the Transport Model building on previous versions. For a detailed description of current and previous versions of TMfS, please see the Documents, reports and guidance section.
As well as updating the model to a new Base Year (2014), additional Park and Ride sites were added to the model and the mode and destination choice models were updated using the latest household travel survey data.
Transport and Economic Land-use Model of Scotland (TELMoS)
A land use model provides a view of future land use and a representation of the interaction between the pattern of land use and transport demand over time.
In 2015, an updated, Transport and Economic Land-use Model of Scotland was developed, with a base year of 2014.
TELMoS14 is the latest version of the Transport, Economic and Land-use model building on previous versions. For a detailed description of current and previous versions of TELMoS, please see the Documents, reports and guidance section.
