The graph shows the speed (MPH) of the truck for up to five minutes before and two minutes after the incident occurred. The moment of the incident is represented by a red line. Depending on the incident type and vehicle equipment, additional information may also be included.
Understanding the Incident Details Search Panel
- Occurred At:
- Where the incident occurred.
- Vehicle ID
- Your company's commonly-used identifier for the vehicle, such as the truck number. You specify the Vehicle ID when you set up the truck in QTRACS.
- Vehicle UA
- The serial number of the Omnitracs mobile unit on the vehicle. UA stands for Unit Address.
- Driver ID
- The ID your driver uses to log into their Omnitracs mobile unit.
- Parking brake status
- Whether the parking brake was on or off when the incident occurred.
- Incident time
- When the incident occurred.
- Incident speed
- The vehicle's speed when the incident occurred.
- State (of CER incident)
- New or reviewed. If reviewed, a CER user has reviewed the incident and taken appropriate action.
- Note (for CER incident)
- When a CER user reviews an incident, he or she can include a note. Usually, this includes what actions are recommended or have been taken.
Understanding the Incident Details Graph
- Speed (blue line on incident graph)
- The vehicle's speed from five minutes before to two minutes after the incident.
- Following Time (black line on incident graph)
- A measure of the distance between the truck and an object (usually another vehicle) in front of it. This measure is expressed as the number of seconds the truck would travel before it struck the object in front of it, if that object suddenly became stationary. Following time is only available if a vehicle is equipped with and enabled for a supported collision warning system.
- Overspeed / Excessive Overspeed Threshold
- An indication that the truck is traveling too fast. CER leverages the overspeed/excessive overspeed trigger in Performance Monitoring (PM). An administrative user of PM can set these thresholds for each vehicle type.
- Zoom Level
- The graph supports three distinct zoom levels. Click the left, middle, or right portion of the control to change zoom level.
- How do I zoom in to see more detail?
- Click the Zoom Level control to view the graph in either the Medium or Max level. Hover the mouse cursor over a point on the graph to see the exact x and y values at that point. This feature is not available at theminimum zoom level.
- Why does the black following time line have gaps?
- The following time shows how close the truck is to the vehicle in front of it. In traffic, smaller vehicles often dart in front a truck for short periods of time. If, for example, a car moves into the lane in front of a truck, then quickly moves to the next lane, the following time may be extremely short for a brief period of time. When the vehicle moves to the next line, the lane in front of the truck may be empty, so the effective following time is "infinity," which appears on the graph as a gap.
