burns has launched an analogue for a long time working in the service of Yandex search optimal routes travel on the subway.
    The interesting thing is the difference in travel time on the same route issued by these services.


    I often use the metro scheme from Yandex myself. Travel time, real and calculated, sometimes differs by a couple of minutes (and Yandex warns about this). But how, probably, the users who believed the email and went to some important meeting were upset.

    Habralyudi, be careful! :)
