Zonar Features · School Bus Suite
Routing, driver directions, student ridership and a parent app in one school bus platform. Here is what each part does and what hardware it needs.

The Zonar Bus Suite is Zonar's school bus platform. It brings route building, turn-by-turn directions for drivers, student ridership tracking, live on-time monitoring and a parent app into one dashboard. Zonar describes it as scaling from 10 buses to 1,000, and it runs alongside Zonar's bus hardware: the V4 telematics unit, the driver tablet and the Z Pass card reader.
Routes can be imported by CSV from an existing routing provider or built from scratch in Zonar. Each route shows on a Google-powered map with its runs, run times and the number of students assigned, and each run lists turn-by-turn directions with the time and distance between stops. Dispatch sets the days a run is active and its start and end times, and can drag and drop to change a run on the fly for substitutions, traffic, weather or a student's needs. Planned-versus-actual reporting compares the schedule with what actually happened, so routes can be tightened over time.
On the Zonar tablet, drivers see their assigned routes and can preview the trip before they leave: the full route, the student manifest and the turn-by-turn directions. Once the trip starts, the tablet gives spoken and on-screen directions stop by stop, and Zonar says directions stay available offline when the signal drops. Built-in two-way messaging lets drivers report delays, emergencies or incidents by text or a pre-filled form, and dispatch is alerted when a message arrives.
Each student carries a passive RFID card. When the student boards or leaves the bus, the scan records the time, the location and the bus number. The driver's tablet confirms the student and the stop, and alerts the driver if the wrong student tries to board or exit at the wrong stop. If a student forgets the card, the driver can add the student by hand so the record stays accurate. School staff and dispatch can see online who is on which bus and where they got on or off, and Zonar states that ridership data is encrypted and handled under student privacy rules.
Zonar's district brochure makes the point that the more easily parents can see where the bus is, the fewer calls dispatch takes.
The dashboard shows how many buses are in transit, not started or finished, and records whether each completed run was on time, early or late. It also shows on a map when and where the stop arm came out and the door opened, and dispatch can message a driver straight from the dashboard when a run goes off schedule.
Bus Suite depends on hardware in the bus. The V4 reports location and logs door and stop arm events through its inputs, the driver tablet docks to the V4, and the Z Pass reader connects through its own cable kit. Zonar states that many Thomas Built buses leave the factory with a V4 already installed, so a district may only need the tablet and reader added. When we install, we wire the door and stop arm inputs and confirm each one changes state before the bus goes back in service.
It suits school districts and bus contractors that want routing, ridership and parent communication in one system rather than three. A district that already has a routing package it likes can import those routes rather than rebuild them, so it is worth asking Zonar which parts of the suite can be added on their own.

Yes. Zonar says routes can be imported by CSV from your route provider or built from scratch in Zonar.
No. Parents can track the bus only while it is on its run and their child is on board, and districts can limit the view further.
The driver can add the student manually on the tablet so the ridership record stays accurate.
