Spain-based company Indra has delivered traffic control technology worth €13m to the cities of Changde, Guilin, Korla (Bazhou) and Liaocheng in China.

The projects include the design, development, implementation and start-up of the traffic control centres in each city.

Under the project Indra will equip each centre with smart traffic monitoring, signalling and traffic lights as well as CCTV surveillance, speed control, traffic violation or user information systems.

The company said the solution will help monitor all systems in real time as well as continuous follow-up of the traffic, which will help optimise the flow of vehicles, reduce travel time, costs and environmental impact while increasing safety.

The follow-up systems in the new solution will help police track down traffic violators through an automatic license plate recognition and management system.
