The issue of road safety is a key one today. The Russian National Project "Safe and Quality Roads" envisages the introduction of new technical requirements and standards for road construction based on digital technologies and the introduction of automated and robotic technologies for road traffic management.
This work proposes the development of an automated software system aimed at improving the driver's perception of the road. The detailed description of possibilities of this system is given and its testing is carried out during modeling of the situation after the introduction of the system on the specific section of M-5 highway "Moscow - Chelyabinsk" between Miass and Ust-Katav.
Complex meteorological conditions, large differentiation of traffic flow and a large number of factors affecting the condition of the road surface characterize this section. Received results confirmed the effectiveness of the proposed system aimed at improving the driver's perception of the road, and as a result, to improve the system of road traffic organization and increase its safety.
The imbalance between the rapidly growing rates of motorization and the unsuccessful development of the transport network leads to the destruction of transport network facilities. On the roads, this problem is solved by updating the coverage. The application of this technology to artificial structures (bridges, overpasses, overpasses) is ineffective.
To preserve artificial structures in a standard condition, it involves the introduction of restrictions on the weight and dimensions of vehicles.
This paper proposes the development of a unified registration automated complex for monitoring vehicles in regular traffic.
The advantages of the proposed automated complex are determined by the simplicity of its use, the formation of a single database collected from existing traffic management systems in real time, automatic processing of the received data and instantaneous measures to prevent violations of the established restrictions.
The approbation of this automated complex was carried out when simulating the situation on the section of the regional road of the first technical category 57K-0002 "Perm - Berezniki" km 22 - km 24 on an artificial structure - a bridge across the Chusovaya river.
The effectiveness of the automated complex on an artificial structure - a bridge across the Chusovaya River is confirmed by the fact that after the start of its operation, the transport and logistics characteristics of this artificial structure have significantly improved.
The goal is to develop a regional innovation model for managing the redistribution of transport flows through their local deceleration. Achieving this goal implies justification of the innovative approach as a key development factor; specificity of the innovative approach for motor transport networks; developing model of organizational efficiency and traffic safety; application this model to the organization and safety of traffic on Perm regional highways. The following methods were used in the article: data analysis method, mathematical modeling method, design and survey method, statistical method. In this paper, we present an innovative automated traffic light system that allows you to redistribute the load on the transport network by applying technical means of organizing traffic without changing the basic parameters of the carriageway.
The article discusses questions of construction of the automated measuring complex intended for parametric control of voltage and current transformers.

Calculations of measurements errors of the parameters of transformers for this complex are made.
This article discusses the mechanisms of «mergers and acquisitions» as strategic tools determining the course of development of the companies with regard to their current status, place on the market, ﬁ nancial opportunities. It is easier for major players to buy a successful startup or a company that has advanced developments in view of the market. As the analysis showed, both SAP and Oracle simply bought IT companies with ready-made solutions in order to enter the market of ERP systems for small and medium-sized businesses. The same thing happened when the number of cloud solutions increased in the market. Acquisition can be considered as one of the ways to put a competitor out of business.
The introduction of IS has a positive impact on the efficiency of companies and organizations. At the same time, even for the a posteriori assessment of the implemented IT projects in terms of these improvements, there are no generally accepted and generally used metrics or frameworks. Traditional approaches make it possible to consider the operating and capital costs of the system, but in terms of the positive financial effect of the introduction, there is a shortage of assessment tools. The situation with a priori evaluation is even more difficult due to the lack of information about costs. For example, there may be errors in estimating deadlines, during the usage of a cascade approach to project management, or uncertain terms in project implementation within the framework of rapid development approaches, unintended integration, indirect effects of implementation, such as reengineering of a number of business processes. At the same time, the systems of the operational level are much more accurate than the systems that support decision-making for the middle and higher levels of corporate governance. Therefore, the decision to implement or refuse to implement an IT project often has the character of expert review, and the cost of an error in making such a decision is very high.
This work proposes an approach for making a decision whether to implement an IT project. It is based on a risk analysis of the company's activities. Large companies, as a rule, build risk management systems, which, among other things, provide a quantitative assessment of the most significant risks and opportunities. Thus, it is possible to measure the positive effect of the introduction of the system as its influence on reducing risks and increasing opportunities in financial terms. This assessment basis will allow to consider IT projects not as costly measures, but in the traditional way of evaluating investment projects, expecting them to have a positive impact on the value of the company.
The primal problem of research consists in finding of number of outcomes of the studied scheme and their transfer in an explicit form. The form of representation of outcomes is for this purpose discussed. On the basis of comparison with the similar scheme with indiscernible particles studied in  with the found number of outcomes of S the apparent formula for number of outcomes of N these schemes expressed through S is removed.
Along with rather laborious analytical calculation of number of outcomes of the scheme N, the assuming preliminary finding of number S on , is offered a numerical method of definition of N at any fixed values of parameters of the scheme (n – numbers of cells and r – number of particles) by creation of a state graph of casual process of poyedinichny serial placement of particles on cells to r-oho step with particular discipline of numbering of the states describing scheme outcomes in the taken form. On the same count with the indication of easily calculated probabilities of transitions from a state to a state procedure of calculation of probability distribution of outcomes of the scheme after placement of the fixed number of particles is offered. Thus, we receive the complete list of all outcomes of the scheme and their probability distribution. Besides, the numerical method of approximate calculation of number of outcomes of the scheme is given by method of stochastic model operation. Questions of model operation of outcomes of the scheme are also considered.
A virtual simulation method has been developed for the early stages of the design of onboard electronic devices and systems (OES). The virtual model proposed for use in the design is an integrated model that implements the interconnection of dissimilar physical processes (electrical, thermal, mechanical, aerodynamic) caused by the simultaneous action of several operational factors on a single device or the entire system. The interconnection of physical processes realized in the virtual model allows for the first time to fully reflect the real physical state of the supporting structure and the complex physical state of the electronic components of the circuit located on the printed circuit boards of the OES. In this case, the output functional characteristics of the OES in virtual modeling take natural values that take into account the influence of external factors on the components parameters of the circuit. Visual images of the design and electronic components of the OES with the color fields of temperature distribution, deformations or mechanical accelerations obtained by virtual modeling superimposed on them make it possible to identify at the early stages of design the most tense and therefore dangerous places in the sense of possible overloads.
The paper proposes a generic methodology for the selection of a specialized CAD-based application of methods for decision support, in particular the method of analytic hierarchy process and the method of preference functions. Bothe methods take into account the opinion of decision-makers (project Manager, engineer and designer). The proposed method makes it possible to automate the process of selecting a CAD on the websites of the distributors from the point of view of the given criteria and restrictions due to the introduction of scales of criteria for the evaluation of CAD. It allows to use the experience knowledge of experts in a particular field and to reduce the time for decision-making if necessary. The choice of specialized computer-aided design are considered on the example of choice of printed circuit boards (PCB design) CAD for industrial enterprises and companies engaged in the development of electronic computing from available alternatives offered on the websites of the vendors, and distributors.

The possibilities of research of combinatorial circuits of particles in cells based on graphs of stochastic processes in the respective schemes poedinichnom adding particles with a specific numbering at each step to organize easily calculable probabilities. Such information enables precise probabilistic analysis of interest layouts. The essence of the method consists in constructing a graph of a random process with poedinichnom adding particles in the combinatorial circuit in all possible ways with certain distinct discipline their numbering in the corresponding graph states. Number of process steps defined in the schema specify the total number of particles placed. We are interested in the list of all the states, and, hence, their number on, the last step. If on, the edges of the graph indicate the probability of all transitions with standing in state at any step of the process, given its properties, the probability of all outcomes scheme calculated by the formulas of addition and multiplication of probabilities and give full information about the process, allowing to conduct further analysis of the scheme. Therefore, the immediate goal of research of combinatorial circuits is to get all of their probability distributions explicitly listed outcomes. A first problem will be solved enumerative combinatorics for all outcomes of interest combinatorial circuits.
