Zebra crossing are quite a crucial feature in the city landscape. They oblige vehicles to stop and give pedestrian right of way. They are a relatively new invention and they come in various shapes around the world. Their most important feature is of course visibility: above all they must be clearly visible.
It is important to stress that zebra crossings are a young design; as such, and as many other road signs, policies and procedures regulating traffic and road sharing, they are quite likely far from being perfect. Designers are hence encourage to rethink the crosswalk even if one should remain prudent when it comes to creative crosswalk.
