This article is about the practice of evaluating driver performance. For other uses, see Telematics.

Driver scoring, also known as driver behavior scoring, is the process of evaluating a driver's performance by collecting and analyzing data related to their driving habits to create standardized driver profiles.[1] This is accomplished using in-vehicle data recorders and telematics devices that gather information directly from the vehicle. The goal is to create an objective measure of a driver's safety and efficiency, often represented as a numerical score.[2]

The practice is widely used in modern fleet management systems to assess risk and promote safer, more economical driving habits.[3]

Methodology

[edit]

The process of generating a driver score involves collecting data from in-vehicle sensors and analyzing it against a set of predefined parameters to identify distinct driving patterns or profiles.[1]

Data collection

[edit]

Driver scoring systems are based on data collected from an in-vehicle data recorder or a telematics device, such as a Telematic control unit (TCU).[2] These devices use a combination of sensors, primarily a GPS receiver and an accelerometer, to monitor the vehicle's movement and driver inputs. The GPS provides data on speed and location, while the accelerometer detects forces related to acceleration, braking, and cornering.[2]

Key parameters and scoring

[edit]

The raw telemetry data is analyzed to identify specific unsafe or inefficient driving events. While the exact algorithm varies, academic and commercial driver scoring models typically evaluate parameters such as:[2]

  • Acceleration and braking events
  • Speeding
  • Engine RPM
  • Idling time

These events are logged and weighted by an algorithm to produce a composite score. This score serves as a benchmark of the driver's overall performance, often categorized into profiles such as "safe," "aggressive," or "economical."[1][2]

Applications

[edit]

Driver scoring has several practical applications, primarily focused on improving safety, reducing operational costs, and promoting environmental sustainability.

Fleet management

[edit]

For businesses that operate a fleet of vehicles, driver scoring is used to improve safety and efficiency. Fleet managers use data analytics to create comprehensive driver profiles, which allows them to identify high-risk drivers for targeted training, reduce vehicle wear and tear by discouraging aggressive driving, and lower liability.[3]

Car sharing

[edit]

Car-sharing companies use driver scoring to monitor the use of their vehicle fleet and manage risks associated with short-term rentals. By tracking driving behavior, these companies can identify and penalize aggressive or unsafe driving, which helps reduce vehicle wear and tear, maintenance costs, and insurance premiums.[4] The score can also be used to reward safe drivers with benefits like discounts, encouraging responsible use of shared assets.[5]

Eco-driving and fuel efficiency

[edit]

Driver scoring is also used to promote eco-driving, a method of driving that minimizes fuel consumption and greenhouse gas emissions.[6] Telematics-based driver scoring provides direct, data-driven feedback on behaviors that waste fuel, such as excessive idling, rapid acceleration, and speeding.[2]

By monitoring these parameters, driver scoring systems can calculate an "eco-score" that quantifies a driver's efficiency. This score helps organizations and individuals reduce their environmental impact and achieve savings on fuel costs. The European Green Digital Coalition lists such telematics solutions as a methodology for reducing emissions in the transport sector.[7]
