This article focuses on a method of drone-assisted assessment of road transportation and exploitation conditions. The nature and types of defects to the road surface and their effect on calculated speed of motion are registered based on the inclusion of a private coefficient. This coefficient is calculated based on the presence, amount, and relative area of motion. The algorithm of this method is implemented as a software programme, which allows to increase operational accuracy of the calculation. Additionally, the developed method allows to implement expedited assessment of an automobile road's transportation and exploitation conditions.

This article analyzes the existing technical means designed to monitor automobile roads and transportation infrastructure, including their main disadvantages. It demonstrates the research results of the potential capabilities of the existing technical means for creating a multifunctional mobile road laboratory, implementation of which would allow to solve a wider range of tasks. These tasks amount to measuring in unfavourable conditions, including the roads without hard surface, searching for automobile roads, conducting water barrier research, and identifying the nature of large damage to the automobile roads and transportation infrastructure. The multifunctional laboratory's equipment is based on the existing technical means, which are resistant to the negative environmental factors. Moreover, some systems are subject to amelioration and additional design, particularly the transverse surface evenness measuring system. Besides the traditional technical systems, which equip the existing mobile road laboratories, the usage of aerial drones is also suggested.
