Driving score

Follow

Driving score is metrics 0..100%, what expresses, how well drivers are driving. Here, 100% is perfect score. Various conditions can bring it down, and this article explains, how it's composed.

Description

Driving score is composed from following aspects:

Driving style

GPS trackers, what can register harsh accelerations, breaks, and turns, send those events to our server, and they can be used to evaluate driver driving style. Smooth driving saves fuel, and vehicle moving parts. (It also may raise your company reputation, if your vehicles have company logo :) So every harsh movement brings down driving score a little.

To use that feature, GPS tracker must support green driving or compatible feature.

There are lots of reports available, what show green driving data.

Overspeeding

Driving over prohibited limit, like 60 km/h, where it is allowed to drive 50 km, brings down driving score. The more speed violated, the harsher effect to driver score.

To use that feature, your account must have overspeeding feature enabled. Overspeeding data is saved to Journal or Logbook, so all trips should be filled there. There are special reports available, speed limit violations, what will show detailed speed events.

Overspeeding data comes from some map service, what has database from existing speed limits of roads. Currently, only one such engine from Google is available. Note that Google may not cover all roads in your country, or its database may not reflect all latest changes, so there's no 100% guarantee of accuracy of that data.

Tired driving

It's not recommended to drive long time continuously, like 2 or more hours straight. So one way to bring down driver score is to drive continuously long time. There is no special equipment or setting needed for using that driving score aspect.

Also, when driver cannot rest enough after long driving, it also affects driving score.

Idling

When engine is turned on, but vehicle is not moving nowhere, it has environmental effect. So it's possible to get extra minus points with long idling. You need such GPS tracker installation, what is able to detect ignition, or when vehicle has engine turned on, like based on higher voltage.

Setting up

Some aspects of Driving score needs special setttings to be enabled outside your organisation settings. Other are available your organisation administrators.

Driver score

Your account manager must enable driver score for your account:

  • set, does its data come from Journal or Logbook

To get running data about speed violations, you have to fill Journal or Logbook, whatever is set up for your organisation. You can set Journal to be filled automatically, under Settings - organisation settings - Journal section.

Turning on use driver score makes available new tab in settings dialog, driving score. It allows to fine-tune, how much various aspects of driver score affect end result, or you may turn off some aspects completely. See section below.

Speed limits

Your account manager must:

  • select speed limits engine from map settings. Currently, only Google is available
  • additionally, enable speed limit violations report, if you're interested in more detailed overview

Green Driving

You need GPS trackers from manufacturers like Teltonika or Ruptela, what support Green Driving or Eco Driving features. Almost all trackers in last ~10 years support that.

  • Your account manager needs to enable Green Driving for GPS trackers
  • For checking green driving raw data, you may be interested in green driving reports, what should be also enabled for your account by your account manager

Settings/Driving score

Under Settings - driving score, you can fine-tune, how driver score is composed, and what value ranges have more serious effect. Effects are in scale 0-4, where 0 turns off using that feature completely, and 3 has most serious effect.

Sections are:

  • Green driving:
    • Acceleration
    • braking
    • cornering
  • speeding under 10 km/h, 10..20, 20..30, and over 30 km/h over allowed limit
  • tired driving:
    • continuous driving over 2, 3, and 4 hours
    • short resting stops below 30, or even 10 minutes
  • Idling over 5, 10, and 15 minutes

Score calculation

Score is re-calculated, when any actions described above happens. General formula is:

DrivingScore = 100 * (1 - penalty / distance)

Here, penalty numbers 0..4 are defined in driver score settings described above. Score drops down one percent with one penalty point per 100 km. Distance is calculated over past 7 days. Each next day, current day is added, and 8th day back is subtracted.

Score is driver-based, although data comes from GPS trackers installed to vehicles. This means that vehicles must use any kind of driver identification. When trips have driver associated to them, system knows, which driver belongs to what trip.
