1. A computer implemented method of providing a transit shed utilizing processed road graph data, comprising:

  • receiving an indication of a location and an indication of a desired travel time,wherein both indications are received via a graphical interface; and

    displaying a transit shed on the graphical interface,wherein the transit shed depicts a geographic area having determined travels time to or from the indicated location via a first mode of transport, the determined travel time not exceeding the desired travel time, andwherein determining the determined travel times includes;

    obtaining, with a computer, road graph data regarding the geographic area to be evaluated;

    processing, with the computer, the road graph data utilizing a set of criteria related to the first mode of transport, the set of criteria being utilized to determine a lower priority portion of the road graph data that is considered to have a lower priority for use when calculating travel times for the first mode of transport as compared to a higher priority portion of the road graph data that is considered to have a higher priority for use when calculating travel times for the first mode of transport; and

    storing, with the computer, the processed road graph data as a set of reduced road graph data to be utilized for calculating travel times for the first mode of transport, the set of reduced road graph data not including the lower priority portion of the road graph data.
