OmniCAV: Simulated Road Users in New CAV Testing Framework


XPI Simulation will be playing a key role in a ground-breaking research project to test and certify connected and autonomous vehicles (CAVs) in simulation.

OmniCAV will lay the foundations for the development of a comprehensive, robust, and secure simulator, aimed at providing a certification tool for CAVs that can be used by regulatory and accreditation bodies, insurers, and manufacturers to accelerate the safe development of CAVs.

Working with a consortium of 11 parties in total, XPI will bring its expertise to bear on the creation of a virtual environment in which a potentially unlimited number of scenarios can be enacted to evaluate CAV behaviour.

XPI will be leading the design and development of the core simulation software that will be used to test CAV, drawing upon the CAV3 feasibility study, Certification of Autonomous Vehicles in Synthetic Environments (CAVinSE), for which XPI is the project lead.

OmniCAV, which was awarded funding as part of a competition run by the Centre for Connected and Autonomous Vehicles (CCAV) and Innovate UK, will be fed by highly detailed scans of real roads, traffic camera data, accident data, and near-miss analyses. These inputs will be used to create a high-fidelity model of real-world roads, which will be populated with realistic artificial intelligence (AI) based road users. OmniCAV will also create an extensive open-access library of simulator scenarios to test CAVs against.

The simulator technology will offer market-leading coverage of a diverse range of road networks including rural, peri-urban and urban roads.

The project will validate the realism of the simulator by comparing its outputs with data measured for the equivalent locations and scenarios in the real world. This will include tests on proving grounds and open roads.

The project will culminate in a CAV being put through the entire end-to-end OmniCAV testing programme, from simulator-only, to controlled environment, to on-road testing.

Through representation on international standard committees, OmniCAV’s results will influence, or lead to the creation of, new international standards to ensure safe deployment and certification of CAVs.

Timothy Coley, Product Specialist at XPI, remarked: “This exciting research is a natural extension of XPI’s leading position in driving simulation systems and software. Developing virtual worlds for autonomous vehicle test and validation draws upon XPI’s expertise in simulation of complex environments for research institutions, armoured vehicle developers and the Defence Science and Technology Laboratory – and we are delighted to be part of a first-class team delivering this capability.”

Kirsty Lloyd-Jukes, CEO of project lead Latent Logic, said: “OmniCAV’s vision is ‘CAVs for All’: bringing safer, smarter, self-driving mobility to urban and rural areas. But first we need to know that driverless cars really can handle our challenging road conditions, on country lanes as much as crowded city streets. Virtual reality “driving tests” are the only way of doing this, which is why we’ve brought together these 11 leading organisations to build a world-first, AI-based simulation of real Oxfordshire roads to securely and reliably test autonomous car safety.”

The partners in the project are: Latent Logic (lead), Admiral, Aimsun, Arcadis, Arrival, Ordnance Survey, Oxfordshire County Council, UK Atomic Energy Authority, WMG (at the University of Warwick), and XPI Simulation. Thatcham Research is providing advice as a non-funded partner.

XPI Simulation

XPI Simulation, a wholly-owned subsidiary of Thales UK, designs and manufactures a range of world-leading, cost-effective simulator systems for driver training and research applications. XPI offers a range of solutions that are fully scalable and flexible according to different budget and performance requirements. XPI’s core capability lies in the development of a flexible and modular software architecture that accommodates the different functions related to driving simulation - including physical hardware interfaces, image generation, database generation, modelling, vehicle dynamics and scenario creation.

For OmniCAV, XPI will be leading the design and development of the core simulation software that will be used to test autonomous vehicles. This activity will draw upon the CAV3 feasibility study, Certification of Autonomous Vehicles in Synthetic Environments (CAVinSE), which XPI is leading. XPI will draw upon the resources of its parent company in order to deliver a design that ensures a root of trust within the simulator, providing a secure environment for OEMs, regulators and certification bodies alike. XPI will also leverage Thales’s experience and expertise in complex, mission-critical domains across defence, aerospace, transport and security.

Latent Logic (project lead)

Latent Logic, formally Morpheus Labs, is a spin-out of the award-winning Computer Sciences department at Oxford University. The company uses state-of-the-art computer vision and a novel machine learning technique, learning from demonstration, to develop high-fidelity behaviour models for motorists, cyclists, and pedestrians. These “smart actor” models are used to create more accurate and challenging virtual environments for autonomous car testing. In 2018, Latent Logic was selected as one of Nvidia’s “top 4 global Autonomous Systems start-ups” due to its innovative A.I. solutions.


Admiral is a FTSE 100 insurance company with 25 years history in delivering motor insurance direct to the UK market. Admiral has now grown to today serving over 4 million motor customers. In more recent years, Admiral has expanded its motor insurance operations to include operations in Italy, Spain, France and the US. Admiral was also first pioneer price comparison in the UK with the launch of in 2002 and now offer a number of comparison sites across the globe. Admiral’s success has been built upon delivering fantastic customer service coupled with a strong underwriting performance.


Aimsun is an international software and services company with a singular focus on algorithms, modelling, and operational know-how for strategic transport planning, traffic engineering and mobility management. Aimsun develops, markets and supports Aimsun Next transport modelling software, which will provide the traffic simulation underpinning the project and developing its interfaces to allow seamless compatibility with XPI and Latent Logic.

Gav Jackman, Aimsun’s UK Managing Director, said: “Our success in the CAVSim competition is an important strategic development for us, allowing us to work with partners in new fields that add to our value chain and bring us closer to OEMs and Tier 1 suppliers as well as forward-thinking authorities such as Oxfordshire. Extending the off-road testbed environment of RACE to a realistic twinned environment of simulation and simulators is an incredible value chain to be involved in.”


Arcadis, one of the world’s leading providers of Design and Consultancy services, has a strong focus on driving innovation in the design, delivery and operation of built and natural assets, including modelling the impact of CAV and new mobility on city and regional policy.

Ordnance Survey (OS)

OS is Britain’s national mapping agency, providing the geospatial framework relied upon by government, industry and the general public. Its role within OmniCAV is to specify, capture and maintain the high-resolution spatial data required within a robust autonomous vehicle simulation environment. OS will work alongside the other members of the OmniCAV consortium to establish a specification and standard for a geospatial dataset to act as the underpinning reference, or digital twin, for CAV simulation. Based on this specification, OS will capture and process data within the OmniCAV test area, using a variety of terrestrial and airborne sensors. OS will encourage as many other parties as possible to utilise and build on this reference dataset, with the aim of developing a scalable UK exemplar built around the Oxfordshire test area. OS’s involvement will also extend into
other key work packages to provide geospatial support through the full scope of the project.
