Abstract
Abstract Introduction. According to DSTU 8814: 2018 “Road bridges. Terms and Definitions” transport facility is a structure to ensure the proper functioning of the road in difficult geological and hydrological conditions, as well as in the case of crossing the road obstacles: watercourses, highways, railways, etc. One of the indicators of safe operation and normal functioning of roads and transport facilities located on them is the dimension of the roadway - the width of the bridge deck, which is intended for the location of the roadway and safety lanes. Problem statement. The designing of transport facilities is a creative, but at the same time responsible process, which in turn is due to certain regulatory restrictions. One of the important designing criteria is the dimension of the roadway. Since the structure is located on the road, the width of the road should be harmonized with it and not create inconvenience to road users by decreasing of traffic speeds or inconveniences for low-mobility groups on sidewalks, the formation of "tunnel effect", etc. Actually, according to the Analytical Expert Bridge Management System (AESUM) in Ukraine, about 30% of structures on public roads have a dimension that does not meet the requirements of regulations on the width of the roadway. And transport facilities with oversized dimensions are more than 60% (9896 bridges and overpasses). The need to consider this topic is to harmonize the rules for the designing of bridges and roads, improving traffic safety and as a consequence increasing the financial efficiency of transportation. Purpose. The purpose of study is to draw the attention of structures owners, customers and design organizations to the importance of harmonious coexistence of roads and buildings located on them. Also, to draw the attention of developers of regulatory documents to the fact that the narrow dimensions of transport facilities can cause difficulties during the repairing works with partial blockage of traffic. Results. “DerzhdorNDI” SE scientists performed an analysis of regulatory documents on the determination of the dimensions of transport facilities for more than 70 years. Conclusions. According to the results of analysis of regulations on the determination of transport facilities dimensions, an example was presented, in accordance with current regulations, when a collision occurs after repairing works, namely the need to install “Road Narrowing” signs. Also the emphasis had been placed on further harmonization of regulations on the designing of roads and transport facilities. Keywords: transport facilities, roads, dimension, road
