Know the impact
before you commit

Immense models the real-world impact of roadworks, closures and diversions on the road network, so highway authorities and their partners can make faster, better-evidenced decisions without the cost and delay of traditional traffic modelling.

We’ve created a simulation platform for mobility systems to better support your decision making

What does Immense do?

Immense builds and maintains calibrated traffic models of your road network.

Immense builds and maintains calibrated traffic models of your road network. You access those models through a web-based platform to test ‘what if’ scenarios – what happens if this road closes?

Which diversion route performs better? What does this scheme mean for journey times, carbon and network delay?

You get quantified answers – in hours, not weeks – without needing specialist modelling expertise or bespoke data collection.

The models are built to DfT TAG standards and validated against independent data, so results can be used with confidence in stakeholder engagement, ECI processes and planning decisions

What Immense delivers for their clients

Our results in the real world

Building on the initial A382 traffic management (TM) planning work, Immense worked in close partnership with Core Highways and M Group on behalf of Devon County Council to take the scheme through a deeper, evidence-led phase of decision making.

A382 Traffic Management Planning

Part 2: from modelling to delivery

Scenario modelling

Five TM scenarios modelled during Early Contractor Involvement (ECI).

Optimal strategy identified

Full road closure identified as the optimal strategy – counterintuitive but evidenced

Huge time & carbon savings

Decision saved approximately 12 months from the construction programme and an estimated 15 tonnes of CO₂ per week

Predictions validated

Model predictions validated against observed journey times after works began.

To ensure safe working conditions and efficient site access, HS2’s main works contractors must plan and manage the impact of construction traffic on local communities and environment, and the road network.

Client testimonials

What our users say

Christine Urry

Head of Network Strategy and Management, Communities Directorate, Buckinghamshire Council

Removing the complexity and delay associated with traditional traffic modelling to enable quick and informed decision making as part of the Council’s Streetworks function. Road works are part of our day to day lives, whether providing essential utility services to residents and businesses or improving the condition of the roads. Immense allows us to better understand the impacts and opportunities to mitigate the effects of major works on our network, particularly within our larger towns.”

Beth Lewis

Principal Engineer at Devon County Council

The A382 programme has been a really excellent use of the Early Contractor Involvement (ECI) process to help shape this Major Route Network upgrade scheme and the delivery processes. The dynamic diversion approach, and the modelling tools and analysis that supported it, have been critical in enabling the programme to proceed, and to mitigating impacts for the surrounding community.”

Stephen Shaw

Area 6 & 8 Framework Manager, HW Martin (Traffic Management) Ltd

The ability to assess traffic management scenarios before implementation gave us the certainty we needed to plan effectively. The modelling helped us manage risk, minimise disruption and provide our client with clear, evidence‑based recommendations, making the overall delivery process more efficient and predictable.”

Rikesh Shah

Former Head of Commercial Innovation, Transport for London

Bringing in innovation from the market directly contributes in helping us to deliver the goals set out in the Mayor of London’s Transport Strategy. As such, we continue to share some of our key problem statements to bring in a wide range of innovators such as Immense through programmes like London RoadLab to test their solutions on our network.”

Aaron Heer

Traffic Manager – Area Central – HS2

The work going on at Immense is incredibly exciting, they really are bringing traffic modelling into the modern age. Being able to utilise the Immense platform and its up-to-date data has been transformative for us and has the potential to rewrite how we use modelling to support decision-making particularly in a dynamic traffic management environment.”

Abby Perry

Innovation & Continual improvement Manager, Core Highways

We have found working with Immense to be very insightful and can see a real benefit in using their traffic modelling platform as part of the Early Contractor Involvement (ECI) process. It has helped to inform our traffic management plans so we can minimise the impact on road users which is important for our clients.

In addition, the analysis provided by the platform has also informed VMS installations for a current set of closures for further works, which again impacts road user experience which in turn can influence their behaviours through the TM. It’s becoming an invaluable tool in our wider toolkit.”

Frequently asked questions

Can you really do it in hours not weeks?

Our powerful simulation engine, hosted in the cloud, runs at 36 x real time. Additionally, our data pipelines and technology, allows us to build and validate models in weeks, rather than months.

Where do you get your data from?

We get data from public available sources, and our trusted data partners. We have built data pipelines to be able to pull data and refresh our traffic models so they reflect the latest network conditions.

How easily can I upgrade my package?

Very easily. Please let us know you would like to do so by talking to your Account Manager, or by contacting us. A member of our team will be in touch to discuss the details.

Who can use the Immense platform?

Anyone. You don’t need specific transport modelling skills or data anlysis background to be able to use it. It has been designed for everyone, and we always welcome feedback on how we can make it better for you! And for the more complex stuff, our experienced team is here to help!

How do you build your traffic models?

We follow DfT’s TAG guidelines to build and calibrate/validate our traffic simulation models. For each curated model we provide Quality Assurance reports describing the main statistics and the quality level of the model.

What’s the simulation engine you use?

We use our own mesoscopic simulation engine. We’ve built it in house, and validated it with research partners throughout the years, such as Transport for London, National Highways, Oxfordshire County Council.
