The atrcile introduces the change of passanger traffic according to hours of the day on the bus routs, which are laid through signaled crossings of streets Kyubisheva - 8 Marta in Yekaterinburg nearby big transfer transport junction in the distric of subway station ""Geologicheskaya"". Recieved data gives an opportunity to identify percentage of buses in the transport stream. It is one of the factors that influences on the calculations of the length of traffic signal cycle. The analysis of received statistical data lets us draw the following conclusion: 1. To reconstract network of streets and provide the maximal traffic capacity on the crossings, it is necessary to consider variable structure of transport flow. 2. To calculate the length of traffic signal cycle it is necessary to consider the bus traffic volume, which changes according to the time. 3.There was determined the change dependency of passanger traffic on hours of the day on the bus routs. It gives the possibility to predict changes in the length of traffic signal cycle. 4. Recieved results can be used to calculate the length of traffic signal cycle and in order to developn an optimized route network of passenger transport.

The statistics of accidents is given in the oil industry. It is shown that the considerable share of accidents in the oil industry is connected with oil transportation and is followed by its spills. Among the known methods of elimination of oil spills application of various types the floating booms in combination with use of new materials and technologies remains to the most perspective and ecologically safe. The floating booms serve for the prevention of distribution of oil on the water area, for simplification of its removal from a surface of the water, and also for utilization of oil on a water surface. In case of fire the oil spill occurs retention it within the boom. The features of the application, relevant structures and elements of floating booms, ways to improve them as the primary means of oil spill response, the effectiveness of the floating booms are considered.

The paper highlights the relevance of the topic and provides an overview of the existing slope stabilization technologies that have gained widespread use, including composite material technologies: composite piles systems and Geocomposite soil reinforcement, the latter being the injection method for improving the bearing capacity of weak soils. The paper summarizes the benefits associated with the use of composite materials and explores the experience of using worn tires to build retaining walls. In particular, two options are described: with stepwise and vertically arranged tires. Building on the existing experience of soil stabilization with geogrids, a new technology is proposed to stabilize slopes using halves of worn tires. The paper also describes the technology for consolidation of tires and securing them against native soil. The theoretic importance of the paper can be seen in improving the slope stabilization technology, and its practical relevance is associated with its application in construction, reconstruction, repair of buildings, structures and linear works (motor and railroads, oil and gas pipelines, other utility lines) built on slopes or in landslide areas..

In this paper basic problems of safety control during metering complex development are observed. The system being analyzed was divided into two parts:low level (energy meters and GSM-concentrators) and high level (GSM-channel and server). These two parts analyzed before making models for each of them. The whole system is considered a queuing system, main techniques are observed. Analytic model is developed for low level of system, and imitational model is developed for high level. The most safety critical element is recognized. The resulting models could be used in future work as an event generators for analytic software.

Results of researches on improvement of quality of the brick made of clay Kagalnik-3 raw materials are presented. It is defined that raw materials contain a large number of particles less than 1 mm in size that complicates receiving press powder of the recommended granulometriya. In addition, because of high sensitivity of raw materials to drying, on samples there are drying cracks influencing durability and frost resistance. It is defined that for receiving qualitative products, except softer mode of drying, for increase in physico-mechanical characteristics it is necessary to add the mineral modifying additive to furnace charge, and to carry out preparation of press powder with preliminary plastic granulation of weight.

The high water demand of high-plastic and mushy consistency of concrete with high value of water-to-cement ratio leads to decreasing of consistency value and strength of concrete and also to shrinkage of concrete increasing. The known ways of excess water removal from the mix of concrete ingredients with water are labor-consuming and not always effective enough. We suggest the way of excess water removal using loose moisture capable materials which are enabled to absorb water intensively when contacting the concrete mix. The capacity of powder-like materials to absorb water can be evaluated with maximum molecular moisture capacity and maximum capillary moisture capacity measurement units. Also the criterion of water absorbing capacity of powders is suggested, and the most effective loose moisture capable material between others is defined.

The calculation of multi-storey reinforced concrete frame building, consisting of apartments, offices and underground parking, against progressive collapse is presented in the paper. Two different ways of simulation of reinforced concrete building against progressive collapse are suggested, needed for estimation of survivability of building structures. The technique, which allows to carry out the stability of reinforced concrete structure to resist progressive collapse, is presented. This method is based on a nonlinear analysis of framed structures under the special load combination and includes dead and live loads, implying that the loading process modeling is fulfilled on the basis of the adjusted step method. The last one is of great importance for simulation of the processes in the whole life cycle of structures. The obtained results show that the offered strength calculation method of the framed structure against progressive collapse considers both geometric and material nonlinearity and also allows to assess survivability of the construction under conditions of emergency events and its stability to resist against progressive collapse. The step method of solving nonlinear problems, applied for modeling of collapse process, is shown to be more appropriate for these cases. We conclude that applying the proposed method of calculation results in more economic use of materials, giving evidence of its effectiveness.
