  • Study of installation parameters of traffic and pedestrian traffic lights

    This article deals with the issue of the installation of traffic lights on the urban road network. A technique has been developed to select the method for controlling pedestrian traffic lights, and a model has been proposed for determining conditions for regulating pedestrian and traffic flows depending on intensity. The installation parameters of traffic and pedestrian traffic lights

    Keywords: светофорные объекты, заторовая ситуация, пропускная способность, методика управления движением, безопасность движения, регулирование транспортных потоков, эффективность дорожного движения, аварийность, экологическая безопасность, интенсивность движения

  • Calculation of coefficient of operating conditions of pipelines of the West Siberian region.

    Calculation of coefficient of operating conditions of the pipeline is presented in article for the West Siberian region. Dependence of service life of the pipeline on this coefficient is presented. The data of samples witnesses received in laboratory of nondestructive control, confirming relevance of this subject are provided.

    Keywords: corrosion, wall thickness, standard service life, pipeline, coefficient of working conditions, diameter, pressure, settlement resistance.

  • The analysis of emergencies on linear part of the main gas pipelines.
