Foothill Transit

About These Maps:

  • Each map shows bus (and rail, if applicable) speeds for Foothill Transit, with a map each for the morning peak, midday, and afternoon peak periods on November 15 2023 (Wednesday).

  • On the map, routes are split into segments corresponding to the distance between two stops, allowing you to focus on specific portions of the route experiencing a slowdown.

  • Route segments are arrow-shaped to indicate direction of travel. Thicker segments indicate more frequent transit routes.

  • State Highway Network routes are outlined in gray.

  • Hover over, a segment with your mouse to see the exact speed, route name, and transit service frequency in that segment.

    • Higher-frequency routes (3+ trips per hour) are especially important, since those slowdowns correspond to more vehicles, and riders, delayed in traffic.
