CGA creates bespoke digital twin simulations that can help validate the safety of autonomous vehicle technology. We also develop smart city resilience models that predict how technologies will operate/interact together in the future, to prepare cities for upcoming crises like pandemics, terrorism, congestion, mobility and poor air quality. CGA Simulation brings futurology to life. We create robust, dynamic and complex simulations that use our own source and destination data to model the world. This allows us to be more experimental, predicting transport and smart city models with data that doesn't yet exist - we've even modelled Covid 19 spread around a UK city. Our digital twin cities/road networks use pattern of life simulations to bring day-to-day interactions to life. The complexity of our models means we can validate the safety of autonomous vehicle technology against a diverse panoply of hazards. We work with academics in the field (University of Liverpool amongst others) to identify niche areas for exploration; our research has led us to intricately model the impact of rain on sensors, an area that had not been previously explored in this way.
