This article examines an approach to digital monitoring of road conditions and transport accessibility in the mountainous regions of Tajikistan based on modern geoinformation technologies. The first section substantiates the need to transition from occasional field surveys to systematic monitoring using satellite imagery, unmanned aerial vehicle data, and a unified GIS portal for the road network. It describes a methodology for integrating disparate remote sensing and ground-based data, as well as procedures for their preprocessing, georeferencing, and validation. Particular attention is paid to the development of a unified GIS portal structure that enables the storage, updating, and visualization of information on road surface conditions and road infrastructure elements in mountainous areas. The potential of geoinformation analysis for identifying areas of accelerated road degradation, assessing the impact of terrain and climatic factors, and calculating transport accessibility indicators for populated areas and socially significant facilities is demonstrated. The proposed approach allows supporting decision-making on road repair and maintenance, increasing the efficiency of limited financial resources, and forming the basis for the implementation of a road asset management system in the Republic of Tajikistan.
