Subway platform gridlock caused by crowds of riders attempting to exit in different directions not only creates unhappy passengers but slows up arriving and departing trains. Juan Carlos Muñoz, a transportation professor in Chile and former ITS Ph.D. student, has found a simple solution.
As he explains, passengers arriving on the 4 line of the Tobalaba station in Santiago exit the train and then head in different directions to leave the station or transfer. This disordered exit creates gridlock on the platform, which increases the time needed to evacuate the platform and reduces maximum train frequency.
