ORGANIZATIONANDOPTIMIZATIONOFSUSTAINABLEURBANTRANSPORT IN THECITYOFSHAHRISABZ
(BGPulse Journal USA, 2026-06-28) Karimov Akmal Akbarovich; Maxmudov Zuxriddin Nuriddinovch
Ensuring the sustainable development of urban transport systems is one of the most pressing issues in the context of modern urbanization. Population growth, increasing motorization levels, and rising demand for transportation require efficient organization and management of urban transport systems. This study examines the current state of the transport system in the city of Shahrisabz and analyzes the key factors influencing its sustainable development. The research employs methods such as field observations of traffic flows, assessment of road and transport infrastructure, analysis of public transport operations, and identification of existing problems. The results indicate that the level of public transport network development in the city is insufficient, traffic flows are highly concentrated on certain routes, and infrastructure for pedestrian and bicycle movement is limited, all of which negatively affect the efficiency of the transport system. Based on the findings, scientific and practical recommendations are developed, focusing on optimizing public transport routes, introducing intelligent transport systems, modernizing transport infrastructure, and expanding the use of environmentally sustainable transport modes. The implementation of the proposed measures will enhance the efficiency of the Shahrisabz urban transport system, improve the quality of passenger services, and ensure environmental sustainability.
RESOLVINGPARKINGPROBLEMSINURBANTRANSPORTPLANNING
(BGPulse Journal USA, 2026-06-28) Karimov Akmal Akbarovich; Begmurodov Begzod Adham o’g’li
This study examines the key challenges related to parking management in urban transport planning and explores modern approaches for resolving parking problems. It highlights the impact of inadequate parking infrastructure on traffic congestion, fuel consumption, environmental pollution, and travel delays in urban areas. The research focuses on smart parking systems, Park & Ride strategies, automated payment solutions, multi-storey and underground parking facilities, and enforcement mechanisms for illegal parking control. The findings suggest that integrating intelligent technologies with sustainable urban planning significantly improves traffic flow efficiency, reduces congestion, and enhances the overall performance of urban transport systems.
IMPACT OF ROAD INFRASTRUCTURE ON TRAFFIC SAFETY IN KASHKADARYA REGION
(https:// journalss.org/index.php/luch, 2026-01-28) Karimov Akbar Akbarovich; Narzullayev Abror Ahror ogli
Road traffic safety is a critical issue in urban areas, where increasing traffic volumes and complex road network structures contribute to a higher risk of traffic accidents. This study investigates the impact of road infrastructure conditions on traffic safety in the Kashkadarya region, using Karshi city as a case study. The research focuses on street intersection density as a key infrastructural indicator influencing traffic safety outcomes. Open-source road network data were extracted from OpenStreetMap and analyzed using Geographic Information System tools. A grid-based spatial approach was applied to calculate intersection density across the study area, and traffic accident statistics were integrated to assess safety performance. A relative risk index was used to quantify the relationship between intersection density and traffic accident occurrence. The results reveal a clear spatial association between high intersection density and elevated traffic risk levels, particularly in central and highly trafficked zones. The findings highlight the importance of incorporating spatial infrastructure indicators into traffic safety assessment and urban transport planning to support data-driven decision-making and targeted safety interventions.
TRAFFIC SAFETY ENHANCEMENT USING INTELLIGENT TRANSPORT SYSTEMS IN KARSHI CITY
(https:// journalss.org/index.php/luch, 2026) Karimov Akbar Akbarovich; Fayzullayev Nurilla Sirojiddin ogli
Traffic safety remains a critical challenge in urban areas due to increasing traffic volumes and complex traffic conditions. This study investigates the potential of Intelligent Transport Systems to enhance traffic safety through improved speed management, real-time traffic monitoring, and data-driven traffic control strategies. The research focuses on the analysis of vehicle speed characteristics and traffic behavior using field observations and analytical methods. Spot speed data were collected and evaluated to identify speed variations that may contribute to increased accident risk. The findings indicate that Intelligent Transport Systems can significantly improve traffic safety by supporting adaptive traffic management, timely incident detection, and informed decision-making. The study highlights the importance of integrating intelligent technologies into urban transport systems to reduce accident risk, improve traffic efficiency, and support sustainable urban mobility planning.
НЕКОТОРЫЕ ОБЩИЕ СООБРАЖЕНИЯ ПО РАЗРАБОТКЕ БИОЛОГИЧЕСКОГО CПОСОБА ОЧИСТКИ ТЕХНИЧЕСКИХ ОБЪЕКТОВ ОТ НЕФТЯНЫХ ЗАГРЯЗНЕНИЙ
(ВЕСТНИК НАУКИ И ОБРАЗОВАНИЯ, 2026-03-30) Хамроев О.Ж.
в данной статье приведены некоторые общие понятий о биологическом окислении органических веществ, в том числе нефтяных загрязнений. Эффективность использования углеводородного субстрата зависит от его химического строения, агрегативного состояния и особенностей ферментативной системы микроорганизмов, культивируемых на данном субстрате. Эти факторы необходимо учитывать при разработке способов биологической очистки технических объектов от нефтяных загрязнений.
