Running an AVL history can produce hundreds of records each day. With so many records, it might be difficult to pinpoint a specific event in time. By using filters you can easily identify when a specific event occurs.

There are two main types of filters in the AVL module: Speed and Sensor.

The Speed Threshold filter can be used to identify whenever a bus travels above a safe speed limit previously determined. To identify a speeding vehicle:

1. Check the Apply speed threshold coloring box and enter a value in the threshold field.
2. Click Display Map Path to show the results on the map.

3. On the map, you’ll see a red arrow indicating the speeding events. Click on a red arrow to see when and where the event occurred, as well as how fast the vehicle was going.

Similar to speeding events, the Sensor Events filter allows you to view specific telematic with the AVL module. For example, you can view the times when the bus deploys a stop arm, opens the door, starts and stops movement, etc. To view sensor events:

1. Scroll up/down to select the sensors you want to include in the Path History from the Sensors menu.
2. Click Display Map Path to show the results on the map.

3. The sensor events appear on the map, each unique icon representing a specific event.
