Sound or voice information concerning traffic lights has been installed at the main crossroads in Krakow, particularly at those with public transport stops and lines. It helps older people to better recognize the current situation at the crossroads which are difficult points in their pedestrian trips.
Signals are of two kinds:
- a direct voice communication together with a green light that encourages pedestrians to enter the crossing or
- simple sound signals while there is a green light for pedestrians.
Some of the kerbs at crossroads were lowered and at the biggest multilevel crossroads, lifts were installed.
On some pavements, special lines have been built in. Thanks to them, blind people can feel when they approach the crossroads.
The key condition for the implementation was constant political support from the City Council and local road authorities (ZDiT and KZK, now called ZIKiT). However, an important factor was always the opinion of blind people organisations (involving also many older inhabitants), which was taken into account each time new voice communications systems etc. were installed.
