Enhanced mapping data

A crucial enabler of Sentience technology is the availability of enhanced mapping data based on the OS MasterMap Integrated Transport Network layer - Ordnance Survey’s national transport dataset.

This extends beyond basic route topology to include details such as gradients, curves, speed limits and probabilistic speed limiting features such as junctions, crossings, schools, traffic calming measures and traffic lights. Specific routes have been captured for the TRL test track as well as a number of predefined routes on public roads close to Ricardo, TRL and Orange development facilities. As such the vehicle control system has advanced and actionable knowledge of the road ahead and can use this to optimise its approach. Mapping including this level of enhanced data is available on a large scale by mapping suppliers such as Ordnance Survey.
