20 Oct 2026New research on the air quality impact of Low Traffic Neighbourhoods in London

Between March and September 2020, 72 Low Traffic Neighbourhoods (LTNs) were introduced in London. There is growing evidence that LTNs provide a range of benefits for residents within the scheme area. However, there are also concerns about potential negative impacts on residents outside the LTN.

The potential benefits and harms of these LTNs were investigated through the Low Traffic Neighbourhoods in London Research Study, funded by the National Institute for Health Research (NHIR135020).

As part of this study, CERC worked with the University of Westminster, the University of Cambridge, Imperial College and London School of Hygiene and Tropical Medicine to publish a paper which quantifies the air quality impacts of five London LTNs.

This is one of the first studies to assess the impacts of multiple LTNs over the same period within the same city, and to use Google API data of live traffic conditions to accurately represent traffic speeds and congestion before and after the implementation of the LTN.

ADMS-Urban was used to model the concentrations of harmful pollutants NO₂, PM₁₀ and PM_2.5 before and after the implementation of the LTNs. Emissions from roads inside the LTNs and along boundary roads were calculated from traffic flow, speed and congestion data. The modelling considered three periods: before the LTN, and the first and second years following the LTN implementation. Year one data captured the immediate shift in road traffic due to the LTNs, while year two represents longer-term changes in travel behaviour.

The modelled concentrations were then used to calculate health outcomes at Lower Layer Super Output Area (LSOA) level.

The study found that annual average NO₂ and PM₁₀ concentrations decreased slightly within the LTNs. Along the boundary roads, the impacts were mixed, but there was no overall increase in pollutant concentrations. The health modelling estimated that the LTNs lead to a modest reduction in the number of deaths and the number of cases of childhood asthma across the LTNs and their surrounding areas, but the size of these effects was small.

16 Oct 2026CERC second in Cycle September UK challenge

Last month, CERC took part in the Cycle September challenge, organised by Love to Ride.

During the month of September, CERC staff cycled a combined distance of 1,487 miles (50 miles a day!), the equivalent of taking 350 kg of CO₂ off our roads.

Each one of our active riders cycled an average of 3 miles each day, showing how small, individual efforts can accumulate across a community. We achieved two-thirds participation, supported by our Cambridge location with its safe, scenic, and well-used cycle routes.

A notable achievement for us was that, out of more than 200 organisations in the SME 20–49 staff category, CERC finished second overall on the UK leaderboard. One of our consultants even won a pair of socks!

The Cycle September challenge is open to companies of all sizes. 224 workplaces across the Cambridge and Peterborough area rose to the occasion. Together, we racked up 150,000 miles and saved 37 tons of CO₂ from the exhaust. Congratulations to all who took part! By taking cars off the roads, we are reducing traffic and therefore air pollution, making our towns healthier places to live.

Cycle September comes around once a year. Mark it in your calendar for next year and encourage your workplace to make a difference.

25 Sep 2026Helping users choose CERC software for air quality assessments, including modelling under EU Ambient Air Quality Directive

A new online resource has been added to our website to help users identify the most suitable software for their specific air quality assessment requirements. This provides a practical starting point for both new and experienced users by presenting common assessment scenarios alongside the corresponding modelling solutions. It also includes a high-level overview of the most common assessment applications that can be undertaken using the ADMS suite and other CERC software solutions, complementing the detailed information about each software package already available on our Environmental software page.

For modellers within the EU, the resource is particularly relevant in the context of the latest European Union (EU) Ambient Air Quality Directive (AAQD) 2024/2881, which places a strong emphasis on the use of air quality modelling as a key component of compliance assessment, source apportionment studies, and the development of air quality plans. It highlights the capabilities of the Multi-Model Air Quality System (MAQS), one of CERC's solutions for addressing these modelling requirements. By coupling the street-scale ADMS-Urban model with regional-scale air quality models, MAQS enables the consistent assessment of pollutant concentrations across a wide range of spatial scales, from local hotspots to national and transboundary levels. This integrated approach aligns closely with the requirements of the Directive, making MAQS well suited to supporting air quality assessment and management within the EU.

18 Sep 2026CERC's Dr Jenny Stocker appointed Royal Academy of Engineering Visiting Professor

Undergraduate engineering students do not always have the opportunity to learn directly from experienced industry professionals. To address this, the Royal Academy of Engineering's Visiting Professors initiative brings industry and entrepreneurial expertise into academia, to enhance teaching, learning and student employability.

We are pleased to announce that Dr Jenny Stocker, CERC Associate Director of Research, has been appointed as a Royal Academy of Engineering Visiting Professor at the University of Greenwich. The appointment supports the programme Industry Software Development Experience Reshaping Computational Engineering Education, led by Dr Jian Zhong.

Jenny and Jian have worked closely together for more than six years, collaborating on a range of research projects and co-authoring six journal papers. Their work has included:

• WM-Air: using the ADMS-Urban model to assess air quality improvements across the West Midlands
• WM-Net Zero: exploring links between net zero policies and positive public health outcomes
• WM-Adapt: generating urban heat island data for a climate risk assessment tool using the ADMS-Urban Temperature and Humidity model

As Visiting Professor, Jenny will:

• Develop hands-on teaching modules that use software engineering tools and approaches to address real-world challenges
• Deliver lectures demonstrating how computational methods taught in the classroom are applied in professional practice, drawing on examples from CERC projects
• Mentor students undertaking final-year projects

The appointment will help students connect their studies with real-world software development and computational engineering practice.

Many congratulations to Jenny and the other appointed Visiting Professors!
