Imagine a digital twin of the Porto Ring Road as your debugging environment. Here is what you would see if you sat with the team for half an hour.

What it is

A microscopic traffic simulator calibrated on inductive-loop data. Agents for vehicles, traffic signals, and an emergency layer; four signal-control policies running concurrently in shadow-A/B.

Three things it shows

  • Peak-hour gridlock propagation — where a bottleneck at junction 14 rebounds back to junction 22 in eleven minutes.
  • Cooperative vehicle behaviour. We can simulate what happens if 10% of vehicles share their speed with the signals.
  • The cost of a signal outage. It's not linear in time. After eight minutes, it is piecewise exponential.

What comes next

This is the kind of asset LIACC's simulation and smart-cities research points towards. If you run traffic for a Portuguese city, talk to us.
