How Effective Is Congestless?

27th March 2026

We are currently undertaking a proof-of-concept analysis in which we will estimate the effectiveness of Congestless, based on a hypothetical deployment within London’s Congestion Charge zone.

Prior to running this analysis, we had sought the assistance of both private and public sector organisations in the form of anonymised or synthetic journey data derived from real-world car journeys. Unfortunately though, for a variety of reasons, it was not feasible to obtain such data for this analysis. However, we did not wish to let perfection be the enemy of good, so we have been working on alternative solutions that will allow us to run a proof-of-concept without the need for a real-world journey list. The publication of the results will be accompanied by a detailed methodology explaining how this was achieved.

What will this analysis tell us?

This analysis will focus primarily on two aspects, namely: 1) the time saving benefits of Congestless; and 2) the capacity benefits of Congestless.

In terms of the time saving benefits, we will begin by modelling journey times at various uptake levels of Congestless. Then, by comparing the mean journey time from each scenario with the mean journey time from the baseline scenario, we will be able to estimate the percentage time savings generated by Congestless at the given uptake level.

A similar approach will be taken for estimating the capacity benefits, but with our focus being to find – for each uptake level – the maximum traffic volume that can be tolerated without an increase in the mean journey time relative to the baseline scenario. For example, if the deployment of Congestless allows for traffic volumes to increase by X% while keeping the mean journey time at, or below, its current level, Congestless would have effectively increased the capacity of the road network by X%.

When will the results be published?

We are hoping to complete this analysis and publish the results in the coming weeks. You will be able to view the results on our Blog and we will also share them via LinkedIn, so please keep an eye on our website and social media pages. In the meantime, if you would like to find out more about this analysis or Congestless in general, please do not hesitate to contact us.
