S5W-22924: Willie Rennie (North East Fife)

Scottish Liberal Democrats

Date lodged: 1 May 2019

To ask the Scottish Government how the Sestran Regional Model (SRM12) takes account of step changes in (a) transport patterns and (b) land use that could result from new infrastructure.

Answered by: Michael Matheson 14 May 2019

(a) SRM12 considers responses to traveller choices such as which route to take, which mode to use and where to travel to. SRM12 can be run for a number of forecast years to help better understand forecast ‘step changes’ over time. These will include “Do-Something” runs in forecast years with a new transport infrastructure option added to the model.

(b) SRM12 is a typical transport model and does not by itself deal with land-use changes. These land-use changes are considered in the Transport and Economic Land Model of Scotland (TELMoS) which provides forecasts of employment, housing and population based on forecast planning data and economic data. SRM12 takes into consideration the outputs from TELMoS to determine the impact of new transport infrastructure options.
