Given the recent energy market, companies that use simulations have a surprise waiting for them on their balance sheets. Computation is getting expensive. Uncomfortably expensive. Engineering excellence to improve it is needed again. The truth is, there always are costs to simulation. 1 hour of full-scale simulation in general...

Animation of Scenarios
Simulation can be a time-consuming process between creating test scenarios, running simulations and verifying the results, especially if something goes wrong. Whether it’s a vehicle not behaving as you would expect or some interaction between vehicles causing one or more to stop following the route they are given, it...
Ray Tracing Algorithms for Radar Modelling
In previous blog posts we have described various aspects of the radar simulator such as the antenna (Modelling of Phased Array Antenna – Claytex), the interaction with matter (Radar Modelling – Reflection of an EM wave – Claytex) and the validation process (Verification & Validation of a Simulation Model...
When driverless cars rode across Europe… in the 80s
The has-been-trieds of technology. They’re inspiring, they’re disheartening. Those innovators who like to chase firsts and ride the moment are in a complicated relationship with them. So what feelings does it stir, when we remind ourselves that the hotly contested self-driving car was already being successfully driven around as...
AVS #7: Legal proof the AV is safe enough
For a senior manager of an ASDE (Authorised Self-Driving Entity), in accordance with the Law Commission Report on Self-Driving (chapter 11.6, p. 210), failure to demonstrate leadership and structural commitment to AV safety, classified as connivance, is soon to be viewed as a criminal offence. It is serious, only...
Verification & Validation of a Simulation Model
Simulation is the way forward to autonomous driving because it is the only way to deliver the level of testing needed to create reliable systems (“(31) Is Simulation the Way Forward to Fully Autonomous Driving? – YouTube”). Therefore, it has become necessary to have traceable, robust Verification and Validation...
Introduction to Safety Estimation using Intersection Matrix Method
As the world wakes up to the stringent safety tests that will be needed for self-driving cars, the team at Claytex has been working on identifying where they’re most needed, in a method we christened the Intersection Matrix Method. Consider a road network that a self-driving car developer wants...
AV Custom Test Metrics Calculators
In the recent year, when discussing with businesses in the CAV sector, we can clearly observe a great variety of projects, with very different goals emerging. This makes the process of validating these systems a challenging task due to the different requirements to validate each system. To face these...
AVS #6: Self-driving vehicle type-approval for public roads in EU
The European Commission has released draft regulation that outlines the legal requirements to obtain the type-approval for CAV operation on public roads. This requires the Safety Case documentation to be approved by a government-appointed regulatory authority in order to attain type-approval. It is based on principles of candour, blame-free...
Introduction to Supervised Learning
Though there are many definitions of machine learning (“ML”), the principal idea is to give an algorithm the ability to improve without programming it explicitly. It gets around the fact that the set of all possible behaviours given all possible inputs quickly becomes too complex to describe and programme...
