Case Study: Anne Arundel County Public Schools achieves accurate bus stop times with Zonar Systems' Ground Traffic Control

Anne Arundel County Public Schools - Customer Case Study

Anne Arundel County Public Schools (AACPS) manages about 600 buses and was struggling with overly optimistic stop times from its routing software, which used simple distance-and-speed calculations and ignored traffic, signals, and stops. This led to inconsistent routes—one bus was reported as running 27 minutes late—creating anxiety and complaints from parents and the community.

AACPS implemented Zonar’s Ground Traffic Control to capture real-world vehicle data, recalculated average speeds, and rebuilt the road network with accurate times, with Zonar support streamlining the data process. The result: reliable published stop times, fewer complaints, increased public confidence, and a county decision to require AVL/GPS on all contracted buses.
