RAILWAY EMERGENCY SITUATIONS PREVENTION SYSTEM BASED ON GEOGRAPHIC INFORMATION TECHNOLOGIES

Abstract

The article deals with the system of emergency situation prevention on railway based on geographic information technologies (GIS), which makes it possible to estimate the influence of railroad defects, industrial objects (factories, plants located near investigated section of the railway) and natural factors (influence of the elements) on traffic safety. The procedures of area maps design for information systematization and display are offered. The algorithm of measurement information processing is developed, based on wavelet transform, that gives the possibility for the definition of railway bed defect parameters immediately after the measurements and does not require accumulation of information for further decryption. Techniques for influence estimation of natural and industrial factors on traffic safety are suggested to provide immediate representation of information for decisionmaking.
