A good book for pedestrian crossings and integration with sidewalk.. A definite must read
On the Integration of a crosswalk (zebra crossing) with a sidewalk (footpath) Bangalore has more raised zebra crossings than any other city. This raised crosswalk have been implemented in considerable locations. In such places, it is important to connect the raised pedestrian crossing to the footpath at the same level thus enabling the the pedestrians including the diasbled to use the cross walk. It is currently noticed that there is a gap between the raised crosswalk and the sidewalk and in some cases they are completely disjoint and at uneven levels.
