tolerance for error

The low height of the pavements cause unwanted car parking on them which makes difficult to use pavements by pedestrians.

The turning points are too narrow that can bring about  dangerous situations.

The height of the step is too much to step out for the pedestrians in one step.

Huge stairs on the overpass causes a high physical effort for this reason pedestrians choose the car roads in order to pass the road.

There is a traffic jam which includes the buses, cars an pedestrians.the frequency of bus stops is not appropriate for such a narrow road, causing  disorders in traffic flow.
