Walking as sustainable mode of transportation:High park is an unusual structure because it was a high rail line in the past which remained unused and after many years city decided to rebuilt it instead of destroy it. Today most part of the park have been constructed.The length of the park is about 1 mile.According to video 1 mile is about 20 blocks which people prefer to use other kind of transport to travel this distance rather than walking.When people walk on it, they experience different spaces. The variety of spaces and view of the park attract large amount of people every day. Walking in this park is enjoyable and these kind of structures can encourage people to walk more.
