Naturally pavements play an important role in pedestrian comfort. In future the quality of pavement and surfaces will be particularly important in a world with more senior citizens and pedestrians with reduced mobility, more rolling pedestrian traffic and more people wanting to take children to the city. It is desirable for surfaces to be even and non slip. Traditional cobblestones and broken natural slate stones are full of visual character, but seldom live up to modern requirements. In places where the character of the old cobblestones has to be maintained, bands of flat granite have to be added to enable wheelchairs, strollers, small children, senior citizens and women in high heels to move in relative comfort. This type of pavement, combining old with new, is used in many cities and can be designed as elegant floors for public space, while paying history its due.
