1. A computer-implemented method for auto-calibrating parameters in traffic prediction, the method comprising:

  • determining, by one or more computer processors, a first subnet of traffic links having an association with a plurality of traffic links in a traffic network;

    determining, by one or more computer processors, a second subnet of traffic links that is associated with the first subnet of traffic links, wherein the second subnet of traffic links has a first traffic predicting accuracy value;

    generating, by one or more computer processors, a set of optimized traffic predicting parameters associated with the second subnet of traffic links;

    storing, by one or more processors, the set of optimized traffic predicting parameters associated with the second subnet of traffic links in a database;

    retrieving, by one or more processors, the stored set of optimized traffic predicting parameters associated with the second subnet of traffic from the database;

    applying, by one or more computer processors, the set of optimized traffic predicting parameters onto a third subnet of traffic links;

    determining, by one or more computer processors, the set of optimized traffic predicting parameters used to calculate prediction results having a second traffic predicting accuracy value;

    applying, by one or more computer processors, the set of optimized traffic predicting parameters used to calculated prediction results associated with the second traffic predicting accuracy to subnets associated with the traffic network;

    wherein the first traffic predicting accuracy value is lower than the second traffic predicting accuracy value; and

    displaying, by one or more processors, a representation of a traffic predicting accuracy for subnets associated with the traffic network.
