Having gone live in April this year, the London ULEZ will expand up to the North / South Circular roads in October 2021.
WSP has been appointed to carry out a traffic modelling based assessment to identify the junctions and corridors most affected by the proposed ULEZ boundary as well as to quantify the junction impacts and rank the scale of those impacts.
Following this, if areas of concern on the road network are highlighted by the strategic study WSP will develop micro-simulation modelling, that will perform highly detailed analysis of highway traffic activity, to assist TfL when it comes to the design of mitigation proposals.
Future demand will also be developed for the detailed models by applying traffic flow changes from the ULEZ models to existing demand.
“As we continue to drive towards cleaner air for London, we are thrilled by the opportunity to contribute towards the planning and implementation of the ULEZ extension”, says Christine Elphicke, Project Manager at WSP. “Our analysis will focus on c.120 junctions between the North and South Circular roads that with our detailed modelling techniques will lead to the success of the extension scheme and improve the air quality in central London.”
