Phasing traffic lights according to air pollution rates at the scale of a city district could soon become a reality.  But this, first, requires overcoming the complexity of air pollution models.

A European research project has tested the use of 3D cameras alongside the highways and sensors embedded in the roadside to detect dangerous, overloaded trucks as they move. The system enables a reduction in accidents, protects the road infrastructure and reduces fuel consumption and pollution by ensuring conformity to weight controls

Total control on a Bavarian motorway: European researchers and German Police set up a test zone for extensive traffic monitoring. Their goal is to identify overloaded trucks which destroy roads and cause accidents and traffic jams

Whether to go for a deluge system or rather opt for a water mist model spraying small droplets, several European countries are rethinking fire suppression mechanisms for their tunnels
