School Bus Tracking and Scheduling

Safe Student Transport – SST

Thoreb North America’s SST system was engineered utilizing technology Thoreb has supplied to the Mass Transit Industry for over 25 years. SST enhances the security, safety, and efficiency of transporting children riding on school buses.

Available Features Include:

School Bus Tracking

Automatic Vehicle Location (AVL) with Stop Predictions provides the ability for a Central Monitoring station to see where the buses are, displayed on a map image or in a tabular format.  SST software will predict when the bus will arrive at subsequent stops by analyzing historical performance and the actual time of when previous stops were completed.

Student Tracking

With the SST ID cards, the system can record the time and location of students entering and exiting a school bus and make this information available to the agreed upon parties.

Real Time Data Collection

Data collection takes place on each bus as the Vehicle Computer records student entry and exit activity, and the buses current location. In addition, a log file can be created which provides a record of when and where the bus has been.

Wireless Data Communications

Data is transmitted by radio-frequency from each bus to the Central Monitoring Office.  At specific time intervals and as stops are completed, or specific locations reached, the Vehicle Computer will transmit data. Utilizing the best communication services and facilities available in the application area, SST can be equipped to use any of the current data communications methods, such as:

  • GSM – Short Messages (SMS), or other cell phone technology
  • Private Data Radio Channels
  • Satellite phone / modem

Central Office Monitoring Station

Monitoring stations communicate with each SST equipped bus and maintain a database of current and previously recorded vehicle and student activity.

Internet (www) accessible information

Systems can be configured that display bus location data on password protected web pages. This makes it possible for administrators and parents to check the status of school buses and students, such as where a specific bus is and when or where a student may have entered and exited a school bus.

Next stop audible announcements

The Vehicle Computer is capable of automatically playing clear, MP3 encoded next stop announcements. The playing of announcements are triggered when a specific distance before a stop is reached.

Student name announcements

As with next stop announcements, the Vehicle Computer can also play MP3 encoded student name announcements when a defined location is reached.

Vehicle Health Monitoring

Critical drive train sensors such as oil pressure, oil temperature, transmission temperature, and
coolant temperature can be monitored by the Vehicle Computer and reported to the central station
whenever predefined limits are exceeded.

Emergency / Duress button

For the driver, a discrete pushbutton can be provided that when pressed, notifies the Central Monitoring Office that emergency assistance is being requested. The central office will immediately know the requesting driver’s bus location, and in some configurations, a microphone mounted near the driver can be turned on remotely to monitor the audio in the bus, which may assist in determining the most appropriate type of response.

Battery Backup with charging circuit

The option provides continued SST operation even if the host vehicles electrical power is
completely lost. This allows the vehicle computer to continue transmitting critical data such as location and Emergency assistance requests to the central office.

Dual Mode communications capability

In geographical areas where significant portions of bus routes do not have adequate wireless data communications coverage, a satellite communications modem can be added as secondary
communications method. The computer will automatically switch to the satellite modem when it fails to communicate using the primary wireless communications method.

Off-route detection and reporting

When a bus fails to reach a defined stop location after driving the known distance from the previous stop, the C90 will trigger an “Off-route” alarm, which is transmitted to the central monitoring office.


For applications where it is expected that Vehicle Computers may frequently need to be moved from one vehicle to another, the Vehicle Computer system can be mounted in a convenient enclosure which doubles as a carrying case. Connectors on the side of the enclosure permit easy connection of antenna and power interface cables.
