Assessing Driver Behavior

When a car is privately owned, it’s up to an individual driver to operate it safely-to stop at stop-signs, follow the speed limit, and be aware of the other drivers on the road.


Owners of a large fleet, however, are responsible for dozens of trucks, tons of valuable cargo, and ultimately the driving habits of their employees. As an owner you can ask your employees not to brake suddenly or make sharp turns, but will they listen? How can you be sure that your employees will follow your advice? The answer, it turns out, is a system which monitors your vehicles’ drivers.


With a driving assessment application, the operator of a fleet can see an objective evaluation of the quality of drivers over time. Such an application can also display more general information about the driving style of fleet units.


The algorithm which helps evaluate overall driving competency is based on data from telematics devices, and includes parameters like speeding, rapid acceleration, sudden braking, and sharp turning; custom criteria can be added based on an organizations’ requirements. Penalties can be levied against irresponsible drivers based on these same criteria.


The key to good driving is maintaining a calm and balanced ride. This formula is optimal for energy management, as well as reducing unnecessary braking and acceleration.

The main criteria for the quality of driving according to the number of logistics companies are:


  • Cargo safety.  In the case of sudden acceleration, especially in a turn, the force of inertia can cause cargo to shift and potentially become damaged. Making sure goods arrive undamaged is one of the primary responsibilities of any shipping company.


  • Traffic safety. Safe driving (in particular avoiding accidents) is also one of the main points to consider when evaluating a driver. After all, an accident can lead to lawsuits, expensive repairs, and damaged or lost cargo which will have to be replaced. According to research on the subject, when a driver accelerates even 1 km/h above the legal limit, his or her probability of being in an accident increases by 10-15%. Speeds of more than 10 km/h above the legal limit lead to a sharp rise in accidents, especially on urban roads.


  • Fuel economy. The first step to saving fuel is taking advantage of the inertia of the vehicle and reducing the total amount a braking a driver does (without sacrificing safety, of course). While an engines output increases with the total number of revolutions, so does fuel consumption. That’s why it is important to make sure that drivers aren’t exceeding the optima (most efficient) speed of a given engine. GPS trackers can be used to determine a driver’s speed, and thereby his efficiency. .


  • Reducing car wear. Exceeding an engine’s optimal speed means wearing it out while simultaneously wasting fuel. To see how well a driver sticks to the optimal speed, you can analyze data from an engine’s speed sensor by connecting to the OBD II and CAN-bus diagnostic systems.



With a vehicle monitoring application that can be customized based on the needs of your organizations and customers, you can be sure your drivers are meeting best practices. Such a tool is perfect for industries like taxi and limousine services, general shipping, and the transportation of dangerous goods.
