“…During the same period, HRV readings were recorded using a Polar H10 device with similar intervals. The obtained values were processed in the MS Excel software and, based on this, the SI values were calculated by the (1).

Problem. The study of the human factor in transport systems is increasingly important, given the rapid level of motorization and the development of the transport industry in general. Accordingly, there is a task of ensuring the appropriate traffic safety level. Today, in this area, are usually taken into account the road conditions and the road`s design parameters, but often miss the role of the "human factor". At the same time, with the development of methodologies and technical items, these issues are partly researched and solved. Thus, during considering issues related to traffic safety, it is necessary to pay attention to the drivers` functional state (FS) and psychophysiological qualities, their reliability, factors of negative impact on their body, etc. Goal. The research aims to establish how the bus driver`s FS changes under the influence of various traffic conditions` factors. Methodology. The approaches adopted in the paper, which are necessary to solve the goal, are based on theoretical and practical principles for determining the indicators of a human`s FS during professional activity, their regulatory values, allowable ranges of change, etc. Results. The obtained mathematical and graphical dependences take into account the change of transport process operator`s FS under the influence of such factors as the bus`s speed, the altitude of the highway and the duration of the driver work. The stress index (SI) is selected as the driver`s status indicator. It is established that its values range from 87 to 342 c.u. It was studied that the increase in speed leads to an increase in the driver's SI by about 35%. During the statistical data analysis, it was also found that the highest values of SI were observed on sections of roads at an altitude of 250 - 320 m and 420 - 500 m. At the same time, during the increase of the driver's work duration, the value of the SI increased by about 25% and could approach the value of 250 c.u. In accordance with the above, it can be argued that there is an influence of the driver`s driving conditions and work on his FS. Originality. The obtained regularities reflect the impact of drivers' working conditions on the value of their FS, which affects the probability of their accident-free operation and, as a result, traffic safety. Practical value. The obtained results allow the creation of recommendations for developing schedules of drivers` work and rest taking into account the traffic conditions on the route and the conditions of driver's work.

Nowadays, the transport industry plays an important role in human well-being and the functioning of any settlement. Transport systems are involved in almost all areas of production and services. Therefore, any failure in its operation can lead to significant material costs. One of the most important such systems is “driver - vehicle - road - environment”. It should be noted, that the main link in it is “driver”. The correctness and duration of decision-making in different road situations depend on the driver`s functional state. This directly affects the level of traffic safety. Consequently, the tasks of modern transport research are the introduction of methods of the vehicle driver`s conditions monitoring and the detection of his fatigue in its early stages. That`s why the actuality of studying the human operator role in the transport process and the creation of modern means of driving assistance are increasing now.

The in‐vehicular networked control system is among the most critical embedded processes. The controller area network (CAN) has prevailed intra‐vehicle communication for decades. Meanwhile, requirements of future transportation systems are expected to emphasise the in‐vehicle communication complexity, which endangers the reliability/safety of the intelligent navigation. At first, this study reviews the recent solutions proposed to overcome the CAN expanding complexity. Challenges that tomorrow's intelligent vehicles may raise for CAN reliability are investigated. The comprehensive coverage of current research efforts to remove the impact of these challenges is presented. Further, the in‐vehicle system reliability of future automated vehicles is also related to the fault diagnosis performances. Hence, different classes of system‐level diagnosis strategies are compared relatively to the requirements of automotive embedded networks. Furthermore, to thoroughly cover CAN reliability engineering issues, focus is given to the automotive validation techniques. The hardware in the loop, real‐time analysis and computer‐aided‐design tools intervene in various phases along the in‐vehicular network life cycle. Parameters that stand behind the efficiency and accuracy of these techniques in validating the new generation of vehicles are analysed. The authors finally draw some deductive predictions about the future directions related to the reliability of the intelligent transportation system in‐vehicular communication.
