Abstract
The article is devoted to the development of a method for estimating the speed of a car on a route, taking into account the evenness of the road surface. It is shown that in the Russian Federation there are significantly more uneven sections on public and Federal highways than there are flat ones. It is noted that information on the indicators of the international road evenness index is collected and used by the Federal road Agency ROSAVTODOR to improve the road safety sections of the Road safety Department. The designs of push meters are considered. Based on the analysis of statistical studies, it is shown that in Volgograd in 2008—2010, the evenness indicators on trolleybus routes exceeded the maximum permissible value by 45...94 %. The essence of the proposed method for estimating the speed of a car on the route, taking into account the evenness of the road surface, is described. It consists in using the dependence of its average technical speed on the evenness of the road surface, obtained as a result of analyzing the processing of data from long-term monitoring of the speed of cars of this type during their operation. It is shown that the method allows you to automate the process of rapid assessment of the average technical speed of cars, and the application of the method will increase the productivity of rolling stock and the profit of ATP. Keywords evaluation method, vehicle, speed, route, road surface evenness
