The decision on the table
Signal timings set junction by junction leave traffic backing up across the network. Coordinating them is a large combinatorial problem the conventional method handles locally.
Mobility · automotive
City traffic signals, coordinated
Signal phases optimised across a city network in simulation: about 20% less vehicle waiting time than the conventional method. A 2020 simulation study delivered through our platform network with a quantum-inspired optimiser; not a field trial.

What we did, with proprietary methods
Signal phases across the network were optimised together with a cloud quantum-inspired optimiser and the vehicle waiting time measured in a traffic simulator against the conventional method.

What happened next
For a client, the next step is the first engagement on this page’s industry: you send one controller and its operating point. You get back the safe-episode comparison against your current model. Two weeks.
