Introduction. The article analyzes the domestic and foreign papers devoted to the study of the transport infrastructure of motor roads and recommendations for its further development. A special place is given to the issues of architectural and construction formation of roadside service network facilities due to the insufficient elaboration of the problem and the almost complete lack of implementation of the available research results. The research object is the structure and content of scientific papers on the most important aspects of forming the roadside infrastructure. The study aims to provide insight to the current situation in the arrangement of major motor roads in Belarus, reveal the most significant domestic and foreign research in accordance with the selected topics, and define the promising areas of building up a service system based on the gained experience and elaborated recommendations . Materials and methods. The study used systematization, structural and comparative analysis, the theoretical generalization of the data obtained in the detailed study of literary sources of domestic and foreign authors. Results. A review of a wide range of studies on the roadside service formation and development in Belarus and abroad was performed. The paper substantiated the need for developing theoretical and practical science-based recommendations based on the results achieved in several important areas. Conclusions. The paper considered and systematized the papers devoted to various aspects of roadside service network formation. The problem issues of infrastructure development and possible ways of solving urgent problems were identified. The most researched aspects of forming the roadside service objects were established. Issues of architectural and construction development of the network closely related to other areas require further studying. The study revealed that matters of motor road equipment with necessary facilities attract the attention of many researchers. Solving the problem of motor road infrastructural development on the quantitative and qualitative levels would assist in settling a whole series of economic, social, and engineering tasks.

Introduction: the methods of roadside service network development implemented in Belarus were identified. Structure, architectural and spatial solutions, and general functional zoning of a service facility territory were considered for the roadside service facilities located along Belarus main motor roads. The study aims at the revelation of typological features of roadside service network elements in Belarus and their structure-based classification as well as the development of the main provisions on the formation of these facilities based on the current situation analysis and prospective lines of building up a service system in the areas of influence of national importance roads. Materials and methods: the work was carried out through systematization, structural and comparative analyses, theoretical synthesis of the data obtained from the detailed analysis of literature and statistical sources, field surveys of roadside service facilities located along the national-importance roads in Belarus. Likewise design estimation documentation for the constructed facilities was applied. During the field surveys, photo fixation and graph-analytic analysis methods were used. Results: the article suggests the classification of roadside service facilities, reveals the methods of network development, considers functional zoning and offers a concept of prospective formation of the facilities in Belarus. Conclusions: theoretical and methodological foundations of the facility formation were developed, which allows accomplishing more reasonable and objective decisions regarding the development of the roadside service network. The developed classification allows defining new approaches to the formation of the network individual elements. The suggested concept of a modular system for the prospective formation of the roadside service in Belarus can form a basis for the initial build-up and temporary transformation of the facilities and the system as a whole and can be used to develop regulatory requirements for their planning structure and architectural and spatial solution.

In the article, a necessity to improve the system for accounting of parameters for additional factors of technical condition of vehicles and road environment facilities allowed for during design and construction of motor roads is substantiated. A procedure for the determination of circumstances and causes of road accidents, taking into account transport, technical and operating conditions, has been developed. An improved algorithm of expert examination with the application of a non-destructive method with use of diagnostic equipment of dynamic impact is offered. The accounting system includes an algorithm of expert examination of road accidents which provides parametric characteristics of objects and conditions for their existence to ensure procedure functioning. Criteria to identify "weak"sections of motor roads are proposed. A model for the implementation of expert examination taking into account parameters of the subsystem "Vehicle–Road" is proposed. A possibility to determine the risk of road accidents, "weak" sections of operated motor roads, development of an automated data base on motor roads, application of research results in expert opinions upon analysis and reconstruction of road accidents is substantiated.

A system for the accounting of road infrastructure facilities' parameters specified during design and construction of motor roads. A study of parameters' condition was performed. Analysis of road accident rate statistics and identification of parameters to assess the efficiency of the proposed road construction activities aimed at the reduction in the number of road accidents were carried out. Actual data on condition parameters with the use of modern automated multi-functional diagnostic equipment were obtained. Actions aimed at the improvement of road infrastructure parameters through traffic safety enhancement, as well as actions aimed at the reconstruction of the motor road or project-supported construction of road segments were developed. Efficiency of the proposed actions was assessed.
