Use the Driver Efficiency Report (Fuel & Energy > Driver Efficiency) to view essential information about driving styles that can affect the fuel consumption and wear and tear of vehicles in your fleet. When you coach drivers on driving style, you can help to reduce fuel costs and reduce your ecological footprint on the environment. For instance, if you identify high torque scores in the efficiency report, you can coach driving behavior to decrease aggressive acceleration instances and reduce fuel consumption over time.
The Driver Efficiency Report primarily supports fleets with heavy duty vehicles and larger commercial vans. For light duty and passenger vehicles, Samsara supports only Over Speed, Idling, and Green Band metrics.
To tailor the report settings to your fleet and drivers, you can weight the driver efficiency parameters (see Driver Efficiency Scores). For example, if vehicles in your fleet spend a lot of time driving on highways, you can assign more weight to the Cruise Control parameter. Conversely, if your vehicles operate with a lot of stops, you can assign more weight to the Anticipation parameter.
To drill down into efficiency scores you can view the following reports:
For each report, you can set the scope in the side bar on the left. The scope can be either Drivers or Vehicles. You can also adjust the scope to display drivers or vehicles associated with specific tags.
Within the Summary view, you can view the overall Efficiency Score of your fleet for the selected time period as compared to the previous time period.
The Summary also displays a trend line graph for all selected driver behaviors for the entire fleet or by tag. You can modify these trend lines by:
-
Comparing certain tags for individual behaviors
-
Changing the score type from grade from a numeric value to a percentage
Below the Summary, you can also see a leaderboard that highlights the top and bottom five tags or drivers depending on your selection.
The tag leaderboard displays the number of drivers and the combined score for the drivers in each tag group.
The driver leaderboard displays the score for each driver.
You can view efficiency scores either by vehicle or by driver depending on your selection in the side bar.
If your fleet does not use driver assignments, you will see Unassigned as the only driver in the Drivers tab. All eligible vehicles are included in the Vehicles tab.
To narrow the focus of your results, you can use the date selector to change the time period, filter by Attributes, filter by Difficulty level, or use the search bar to find individual drivers or vehicles.
The Score Distribution chart helps you identify at a glance how all your drivers or vehicles are performing and can serve as another method of filtration for the report. If you drag the slider or select a bar in the chart, you can limit what score ranges appear on the report.
You also have the option to control how the report presents data: select 99 to view data metric scores, or select % to view a combination of percentage and raw data.
By default, the report is sorted alphabetically by driver. To organize the report by a different metric, select the metric name (such as Overall, or Difficulty) to view the metric by ascending order. If you select the metric again it switches to descending order.
The report displays the following information for each driver or vehicle:
|
Field |
Description |
|---|---|
|
Driver or Vehicle |
Name of the driver or vehicle. |
|
Overall |
Overall score across all parameters. The default score varies according to region (in Europe the default is A-G and in North America the default is 0-100). Based on the selected view of the table (99 to view score or % to view a combination of percentage and raw data), the score is shown as one of the following:
|
|
Difficulty |
Level of driving difficulty over a given period of time (e.g. one month), based on the Weight and Topography scores displayed in the Difficulty Summary. To view the Difficulty Summary, hover over the Difficulty score for an individual driver. |
|
Cruise Control |
Time a driver uses cruise control in proportion to driving time. |
|
Coasting (Any Gear) |
Time spent without engaging the accelerator or brake in proportion to driving time. |
|
High Torque |
Time the vehicle engine torque is greater than 90% in proportion to driving time. |
|
Idling |
Time when the vehicle's engine is idle and PTO is not engaged in proportion to the engine on time (driving time plus idle time). |
|
Anticipation |
Quick breaking events (based on time between accelerating and braking) in proportion to total braking events. The default is < 1 second after accelerating. You can adjust the threshold value to 5 seconds or less. Samsara recommends you use the default setting and monitor scores for 1-2 active weeks before you make threshold adjustments. Once the threshold is changed, it is applied to future reports and historical scores are not affected. It can take up to 24 hours for changes to take effect. |
|
Green Band |
Time in efficient RPM in proportion to driving time. The default is default is 800 - 1700 RPM. You can define your own green band range between 0-9999 RPM. Samsara recommends you use the default setting and monitor scores for 1-2 active weeks before you make threshold adjustments. Once the threshold is changed, it is applied to future reports and historical scores are not affected. It can take up to 24 hours for changes to take effect. |
|
Over Speed |
Driving time spent over the efficient speed threshold. This threshold is not the same as the speed limit, but rather the maximum speed you would like drivers in your fleet to travel for efficiency reasons. As a best practice, you can adjust the value to reflect a target maximum for your drivers that are specific to the vehicles they drive. By default, a 5 mph leeway is added above the target maximum threshold you set. The default threshold varies depending on region (80 kmh or 50 mph). |
|
Wear-free Braking |
Time spent using wear-free braking instead of friction braking (pedal braking), in proportion to all braking. Wear-free braking includes engine braking and retarder braking (for example, exhaust braking or hydraulic braking), and reduces brake wear and lowers fuel consumption. |
|
Driving Time |
Total time the vehicle has been on and moving (excludes idle time). The drive time relies on the engine state reported by the vehicle without considering a minimum speed. The drive time can differ from the Activity Report and reports within Safety Overview, as these reports rely on trips and take a minimum movement speed of 5 mph to determine when a trip starts or ends. |
|
Engine On Time |
Time a driver spends with the engine on. Driving time plus idle time. |
Driver behavior can be impacted by vehicle weight as well as terrain, which is why Samsara provides visibility into Difficulty over a given period of time (e.g. one month), based on three scores displayed in the Difficulty Summary. To view the Difficulty Summary, hover over the Difficulty score for an individual driver. The difficulty score is only shown as additional context and does not impact the actual driver scoring.
The Difficulty Summary includes the following information:
|
Field |
Description |
|---|---|
|
Overall difficulty score |
The combined average, rounded up, for Topography and Weight scores. An overall difficulty score makes it easier to compare the difficulty level that drivers had to operate in that was out of their control. For vehicles that don't report average vehicle weight, the overall difficulty score equals the Topography score. For example, if a Topography score is 2, and the Weight score is 5, the average is 3.5. Rounded up this results in an overall difficulty score of 4. |
|
Weight |
The average gross weight of all vehicles (including trailer and load) driven during a period. Currently available for J1939 (HGV) vehicles only. 1-5 scores for average vehicle weight is defined by the following:
|
|
Topography |
Also known as high grade driving, this is the time spent driving on high grade rows greater than 2%, either uphill or downhill. The elevation data comes from vehicle GPS data. 1-5 scores for Topography are defined by the following:
