installation of an in-vehicle eco-driving navigation system that instructs the driver on fuel-efficient driving. These systems are being installed in official vehicles, private vehicles and taxis. The system detects sudden accelerations, abrupt slowdowns, harsh braking and idling, and calls the driver's attention to these problems by means of a computer-generated voice and a monitor display. The data can be saved to assess effects.
