Assessment automation of road traffic safety with account for road conditions of an individual itinerary

Abstract

The paper substantiates the need to develop an automated system for traffic safety assessment in urban agglomerations, taking into account road conditions. The authors suggest a methodology for assessment of road traffic accidents, which makes it possible to take into account a wide range of factors affecting them. The methodology is based on complementing the traditional approach of final accident rate calculation with algorithms for collecting and analyzing data using Big Data tools, in particular, convolutional neural networks, fuzzy neural networks such as ANFIS, and cluster analysis using the k-means method. All accident rates are grouped according to the principle of homogeneity of acquisition of information for their calculation. Further, one of the data processing tools is applied to each group. As a result, labor intensity is reduced and the effectiveness of the application of the method of final accident rates increases. For practical calculations, the authors have developed a client-server application that uses data on geometric characteristics, current traffic situation, weather and climatic effects at the time of the trip along a specific itinerary. By means of application use, the analysis of traffic safety on a number of routes in Volgograd was carried out and the results are presented in comparison with the calculations made via the traditional method. It is shown that the use of information about the current situation on a specific section of the road network in terms of the current time significantly increases the accuracy of calculations.

Parameters of the access road for disaster situations on the roads in the mountain area

“…Therefore, measures such as the installation of emergency access roads, parking lots or widening the roadway in recreation areas are the most necessary conditions for ensuring safety. If such measures are not provided during the road repair, safety measures should be implemented before the repair [5][6][7][8][9][10][11][12]. However, the measures listed above cannot exclude the sudden breakdown and stoppage of cars on the roadway.…”
