Determination of the treated area of the road based on geospatial analysis of snowplow trajectories

Abstract

The article is devoted to the issue of improving control over the performance and accounting of maintenance work on highways in winter using the example of snow removal operations on highways, including federal ones. Special attention is paid to a set of indicators that are used as the basis for methodological support for the development of an algorithm for monitoring completed snow removal operations. Such algorithms are used in typical automated dispatch systems for monitoring and controlling road equipment involved in the maintenance of highways (for example, in the PTC Dortransnavigation, used by the Federal Road Agency). The authors of the article believe that the work control algorithm needs to be improved so that it takes into account the actual treated area of the road. To do this, it is proposed to use a geospatial analysis of the trajectories of harvesting equipment, in which the actual treated area is calculated using a graphical method, taking into account the width of the cleaning equipment of road vehicles that were involved in the task. As a result, a function is being developed to calculate the percentage of work performed based on a pre-determined planned area. The planned area, in turn, is determined by the sum of the areas of digital geofences from the task order. The introduction of a new algorithm that performs the calculation of these works, taking into account the treated area, into standard automated dispatching systems for monitoring and controlling road equipment will strengthen the control of snow removal equipment for maintenance of highways, including federal highways, in winter.
