Grading Method
Grades
: Each criteria is given a grade of A, B, C or D and anything lower is given a
grade of F for fail. Therefore each grade will be assigned a limit that if exceed, the
score will go down to the next grade. If the driver exceeds the limit for the D
grade, they will be given an F.
Weights
: Each criteria can be given a different weight when calculating the safety
and eco grades to provide flexibility to the operator in assessment.
Grading & Scores
: Each grade is assigned a score; A=100, B=80, C=70, D=60,
F=50. With this score, the safety and eco‐scores are assessed by a weighted
average of the relevant criteria scores.
The total score is an average of the safety and eco scores.
Below is an example of how scores can be calculated for each criteria.
For example, lets say two drivers received the below scores in each criteria. With
these set weights, their grades would come out as shown below.
Eco grade Weight Driver 1 Driver 2
Sudden Start Count 20 A(100) C(70)
Acceleration Count 10 A(100) A(100)
Brake Count 20 C(70) A(100)
Speeding Count 20 A(100) C(70)
Speeding Duration Ratio 10 C(70) A(100)
Peak Speed Relative to Speed Limit 10 A(100) A(100)
Average Speed Relative to Speed Limit 10 A(100) A(100)
Excess Eco‐speed Count 91 88
Excess Eco‐speed Duration Ratio A B
[Driver 1]
Eco score = 20*100/100 + 10*100/100 + 20*70/100 + 20*100/100 + 10*70/100
+ 10*100/100 + 10*100/100 =
91 = Eco grade A
[Driver 2]
Eco score = 20*70/100 + 10*100/100 + 20*100/100 + 20*70/100 + 10*100/100
+ 10*100/100 + 10*100/100 =
88 = Eco grade B
Although both drivers received a C in two different criteria, each score is
weighted, and therefore the eco grades differed.

Graph Display Settings
The results of the driver analysis can be shown on a graph. To adjust the graph
display, click on the ‘Graph Display Settings’ option.
Max Speed
: Set the graphs upper speed limit (0‐999 km/h)
Max G ‐ Sensor
: Set the graphs upper G‐Sensor limit, by selecting a value
from the drop down menu (+‐1G, +‐2G, +‐3G)
Zoom Window Display Time
: Set the time scale for the graph to be in
zoom mode by selecting a value from the drop down menu (1 min ~ 10
mins).
The graph settings will applied to the following window displays: Manual
Mode, Data Search, Driving Data and the Zoom Graph.
Default settings are: Max Speed (100 km/h), Max G‐Sensor (+‐1G), Max RPM
(3000).
