What about pedestrians?

• lalos 7y ago
  Crosswalks with buttons to signal a red light for traffic (this is quite common in big cities in the USA) and/or pedestrian bridges in highly transited areas (not as common).

    Assuming there will be no people walking in the roads is not realistic.

    It differs by locale--in my experience on the West Coast pedestrians tend to follow the signals more--but people don't reliably follow walk/don't walk signs.
