On February 1 was introduced in A Coruña 'Green wave', which will give priority of step buses at intersections with traffic lights to private vehicles, and whose implementation carries out Acisa in the months of August and September.

Tested in other cities of Spain and of Europe, the system consists of the introduction in buses and traffic lights of devices that will make these ahead of green time or spread it (depending on the case) to give way to the bus when it approachesretaining at the same time and to the extent possible existing at each crossing regulation strategy. In this way we avoid sudden changes in signs that can cause confusion in the driver, worsening the conditions of movement and unwanted road insecurity situations.

In cases in which the traffic light is green when the bus approaches, the role of devices will be maintaining the traffic light at that been long enough as to which the bus pass before the change to red.
