Indefiniteness of the pedestrian - vehicle traffic

As it is seen in these examples, there exists a chaotic situation... 

Pedestrians are afraid of crossing over the street and the area doesn't seem to have any order in terms of both the pedestrians and vehicles. 

  

 If there was a specification for pedestrians to cross over the street, in other words, if there was any arrangement or any perceptible information arranged for pedestrians, the woman below wouldn't have to be running in a scared way!
