Basic data that can be obtained from the tachograph charts, are data on:
- time of vehicle operation during the day,
- odometer of the vehicle during the day and
- vehicle speed in each moment during the day.
These data are important, on the one hand from the standpoint of traffic safety, ie, the expert opinion of accidents, on the other hand, are important from the standpoint of vehicle owners, to control the operation of the vehicle or to obtain certain parameters of the vehicle or the fleet.
Here we will deal with the data from the tachograph charts, which can serve to obtain certain parameters of the fleet.
On the tachograph chart, there are basically three axes (Figure):
- A axis - is the distance traveled by the vehicle and in the following way,
- B axis - refers to the time of vehicle operation and
- C-axis - is the vehicle speed.
From this tachograph chart, we can read that the vehicle:
- began its work in 6 hours and 20 minutes,
- completed its work in 15 h,
- stood from 7 h 45 min to 8 h, from 8 h 55 min to 9 h and 10 min and from 12 h and 45 min to 13 h and 5 min. (standing less than 15 min. was not taken into account)
- a total passed 232 km.
Based on the data read from the tachograph charts, we can make the following table:
"Spent at work h" we get when we take away "Started in h" from "Done with work h".
"Spent driving h" when we get from "Spent at work h" take away "Stood h".
"Utilization of time spent at work" is the ratio of time spent driving and time spent at work. This indicator tells us about how much of the total time spent at work, our vehicle was in a state of movement. In our case, the vehicle was moving approximately 90.35% of the total time spent at work. This indicator is important to us because the vehicle earns money, ie. is useful only when moving. Thus, the higher the utilization ratio of time spent at work, it is better for the owner of the vehicle. However, in connection with this, there are certain legal limitation. Specifically, during nine hours of driving, which is the maximum allowed for a driver for one day, the driver must make a break from 45 minutes, minimum. Which means that the maximum value of this coefficient 0.9231.
More complex analysis of fleet work, is possible when with this data, obtained from the tachograph charts, cross the data about the vehicle operation, ie. data on how much cargo is transported, as the vehicle passed miles with the cargo of the vehicle had a tour in which distances and more.
This will be the topic of the next blog.

Based on the data read from the tachograph charts, we can make the following table:
| Date | Started in h | Done with work h | Spent at work h | Stood h | Spent driving h | Driven km | Utilization of time spent at work |
| 3.3.2011. | 6:20 | 15:00 | 8:40 | 0:50 | 7:50 | 232 | 0,9035 |
| | | | | | | | |
"Spent at work h" we get when we take away "Started in h" from "Done with work h".
"Spent driving h" when we get from "Spent at work h" take away "Stood h".
