Scores are points given to drivers based on their driving behavior. It helps you identify best-performing drivers, as well as high-risk drivers in your organization.

Azuga generates scores for events such as hard braking, speeding, hard acceleration, idling, cornering, distracted driving, and seatbelt usage. It calculates scores on a scale of 0-100.

Scores are generated daily, for the previous day’s driving.

Safety Score Calculation 


The safety score is the sum of all event scores. There are 64 different permutations of score calculations based on the events enabled/disabled.


Some of them are listed below:


1. When all the components are enabled,


Safety Score  = 30% Braking + 10% Speeding + 10% Acceleration + 10% Idling + 10% Cornering + 20 % Distracted Driving + 10% Seatbelt


2. When Cornering, Distracted Driving, and Seabelt are disabled,


Safety Score = 40% Braking + 30% Speeding + 20% Acceleration + 10% Idling 


3. When Cornering and Seatbelt are disabled,


Safety Score = 30% Braking + 20% Speeding + 20% Acceleration + 10% Idling + 20 % Distracted Driving 


4. When Cornering and Distracted Driving are disabled, 

    

Safety Score = 40% Braking + 30% Speeding + 10% Acceleration + 10% Idling + 10% Seat belt



Note: Each score is multiplied by appropriate weighting based on the events enabled/disabled then.


Based on the safety score, driving behavior is classified as:

  • Safe Driving (Score > 75)
  • On the Watch List (65 < Score > 75)
  • Risky Driving (Score < 65)



Braking Score


For every hard-braking event, Azuga generates an event score on a scale of 0-100.

 

Factors used for calculating the event score are:


  • Magnitude of the event - If it is a hard braking or hardcore braking event
  • Time of the event - If it was during high, moderate, or risk hours 
  • Weather (snow, rain)


Braking score is then calculated by taking the sum of all the event scores and normalizing it by the relative miles driven. 

(Relative miles driven is the proportion of miles driven by a driver to the maximum miles driven that day by any driver of the fleet.)

 

The final score is adjusted such that a driver with two hard braking events gets a braking score of 70. 


Speeding Score


For every speeding event, an event score is generated based on a scale of 0-100.

 

Factors used for calculating the event score are:


  • Magnitude of the event - Obtained by comparing the average speed of the vehicle with the maximum permitted speed of the state in which the speeding event occurred and the duration of speeding.

When the SpeedSafe package is enabled, the magnitude calculation also takes into consideration the speed above the PSL (Posted Speed Limit) for that particular road. In this case, the duration of PSL event will be the tracking frequency set for the vehicle.

  • Time of the event - If it was during high, moderate or risk hours 
  • Weather (snow, rain)

The speeding score is then calculated by taking the sum of all the event scores and normalizing it by the relative miles driven. (Relative miles driven is the proportion of miles driven by a driver to the maximum miles driven that day by any driver of the fleet.)

 

The final score is adjusted such that a driver with two speeding events gets a speeding score of 70. 


Idling Score


Idling scores are calculated based on the proportion of trip idling time to the total trip time over the entire day and normalizing it by the relative miles driven. (Relative miles driven is the proportion of miles driven by a driver to the maximum miles driven that day by any driver of the fleet.)

 

The final score is adjusted such that a driver with 21% idling gets an idling score of 70. 


Note: Azuga generated idling scores only when the idling proportion is greater than 10%. 



Acceleration Score


For every hard acceleration event, an event score is generated based on a scale of 0-100.

 

Factors used for calculating the event score are:

  • Magnitude of the event (hard acceleration or a hardcore acceleration)
  • Time of the event (high, moderate or risk hours)
  • Weather (snow, rain)

 

Acceleration score is then calculated by taking the sum of all the event scores and normalizing it by the relative miles driven. Relative miles driven is the proportion of miles driven by a driver to the maximum miles driven that day by any driver of the fleet. 

 

The final score is adjusted such that a driver with two hard acceleration events gets an acceleration score of 70. 


Cornering Score


Scores are generated for cornering events only if you activate the Alerts > Cornering package.

Factors used for calculating scores for cornering events are:

  • Speed of the vehicle
  • Vehicle class
  • Spatio temporal index

Distracted Driving Score

Scores are generated for distracted driving events, only for drivers having the Distracted Driving package as well as the Admin > Roles > Mobile > Distracted Driving privilege.


  Factors used for calculating scores for distracted driving events are:

  • Phone usage duration
  • Speed of vehicle
  • Spatio temporal index (zip code, time of day, seat belt use, etc.)


 Seatbelt Score


The seatbelt score is calculated for drivers who are paired with vehicles (devices) having the SeatBelt package, and it is based on the percentage of seatbelt usage of drivers.
