Testing of the sectional average speed control system began today. The tests are being conducted by the National Toll Authority in cooperation with the Bulgarian Institute of Metrology and are aimed at verifying the accuracy of the measurements before the system's introduction. The procedure will conclude with the type approval of the measuring instruments, according to the press center of the regional ministry.

The tests will be carried out on the Northern Speed Tangent in Sofia, along a 10.278 km section. A total of 500 vehicle test runs are planned, at different speeds, in different weather conditions and at different times of the day. For each test run, the actual speed of the vehicle will be compared with the speed recorded by the system according to a pre-approved methodology.
