Telematics on urban passenger transport

The monograph discusses the application of telematics in dispatch control systems in urban passenger transport. The role of telematics as a technological basis in automating the solution of control tasks, accounting and analysis of the volume and quality of transport work in modern dispatch control systems on urban passenger transport is shown. Analytical models have been developed to estimate the capacity of a high-speed bus transportation system on a dedicated line. Mathematical models and algorithms for predicting passenger vehicle interior filling at critical stages of urban passenger transport routes are presented. The issues of application of the concept of the phase space of states introduced by the authors to assess the quality of the passenger transportation process on the route of urban passenger transport are described. The developed classification of service levels and their application in order to inform passengers at stopping points about the degree of filling of the passenger compartment of the arriving vehicle is described. The material is based on the results of theoretical research and practical work on the creation and implementation of automated control systems for urban passenger transport in Russian cities. The material of M.H. Duque Sarango's dissertation submitted for the degree of Candidate of Technical Sciences in the specialty 05.22.10 "Operation of motor transport" was used. It will be useful to specialists in the field of telematics on urban passenger transport.

REVIEW OF RESEARCH OF THE INFLUENCE OF THE ELECTROMAGNETIC FIELD ON HUMAN WORKING WORK AND DEVELOPMENT OF METHODS OF ELECTROMAGNETIC WAVE SCREENING

This article discusses the issues of life safety of living objects under conditions of constant influence of an electromagnetic field on them. A planned laboratory facility for further research has been proposed. The mathematical apparatus of the generated electromagnetic field by the traction electric motor by the rolling stock of electric transport is shown. Conclusions are made that suggest the creation of special protective clothing for everyday use by humans with a constantly acting electromagnetic field in a man-made environment. Modern man is constantly in the zone of electromagnetic radiation, the influence of which cannot be avoided. Only by minimizing radiation by avoiding areas with increased electromagnetic activity and developing modern means of protection can ensure a safe and harmonious stay of a person in a modern technogenic environment of existence. If we turn to statistics and analyze the issue of the impact of electromagnetic radiation on the human body and study the problems that arise after its negative influence, we will find that almost all human systems and organs are negatively influenced with destructive consequences. This article discusses the latest developments in the field of electromagnetic waves on the human body. The most actual problems connected with work of electric transport as the technogenic environment are analyzed. The mathematical apparatus and the equation of the electromagnetic field for the electric motor are offered to create the mathematical models showing dependence of growth of an electromagnetic field depending on operating modes of the vehicle and places of stay of the passenger in vehicle interior. Еlectromagnetic radiation in the form of clothing, which will allow a comfortable and safe stay of people in a new man-made environment.

Vehicular Bidirectional Internal Antenna with Asymmetric Gain Characteristics to Compensate for Backward Link Path Loss due to Interior Obstacles

Wireless communication technologies are expected to become essential in future self-driving vehicles. This study presents an antenna for vehicle wireless communication with a bandwidth of 75 MHz at a Wireless Access in Vehicular Environment frequency of 5.885 GHz. To compensate for the backward link path loss from the vehicle interior and passengers, the antenna is designed to have asymmetric gains of 0 and 6 dBi at 0° and 180°, respectively. The antenna is validated through an outdoor road test. We measured the received continuous-wave (CW) power, received signal strength indicator, and packet-delivered ratio (PDR) of the digital signal under vehicle-to-vehicle communication mode. Similar power is received in both the backward and forward scenarios. The forward and backward PDR are also similar.
