One of the nicest improvements I've noticed in Mashhad is the new bus stops. They all now look the same and include a metal-glass shelter, bench, and a big map of the route(s) (a schematic view of the stops and an actual city map). The bus loading area is marked with yellow zigzag stripes. The bus fare is paid electronically in the bus with a contactless smart card. No timetable or bus frequency information is yet shown in the stop though.
