The objective of the present study is twofold: firstly, to classify the urban street network in the city of Karbala; and secondly, to evaluate its effectiveness. Following the delineation of the area of study, traffic data is collected through the utilisation of video imaging technology and subsequently extracted from video files. Following this, the city streets are divided into multiple sections, and the speed of movement in each is calculated, as well as the speed of free flow. The primary objective of this study is to determine and compare the level of service (LOS) of a road based on Highway Capacity Recommendations (HCM 2000), including traffic speed, capacity to assess each segment of the network. The findings of the study revealed that roads of the first category constituted 25% of the total, while roads of the second category comprised 75% of the total. Furthermore, the level of maintenance of street sections is 25% when working with LOS C, 31.25% when working with LOS D, 12.5% when working with LOS E and 31.25% when working with LOS F, according to the assessment of transport operations based on average traffic speed.</p></abstract><trans-abstract xml:lang="ru"><p>Знание характеристик дорожной сети является важным фактором для принятия основных мер по повышению эффективности дорожного движения и сокращению задержек. Таким образом, целью исследования является классификация и оценка эффективности городской уличной сети в городе Кербела. После определения района исследования данные о дорожном движении собираются с помощью технологии видеоизображения, а затем извлекаются из видеофайлов. После разделения городских улиц на несколько участков была рассчитана скорость движения на всех участках и скорость свободного потока. Основная цель состоит в том, чтобы определить и сравнить уровень дорожного обслуживания (LOS) на основе рекомендаций по пропускной способности автомагистралей (HCM 2000), включая скорость движения, пропускную способность для оценки каждого сегмента сети. мы обнаружили, что дороги первой категории составляют 25 % от общего количества, в то время как две категории второй категории составляют 75 % от общего количества. А уровень технического обслуживания участков улиц составляет 25 % при работе с LOS C, 31,25 % при работе с LOS D, 12,5 % при работе с LOS E и 31,25 % при работе с LOS F, согласно оценке транспортных операций, основанной на средней скорости движения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>free flow rate</kwd><kwd>average speed</kwd><kwd>throughput</kwd><kwd>level of road service</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>свободный поток</kwd><kwd>средняя скорость</kwd><kwd>пропускная способность</kwd><kwd>уровень дорожного обслуживания</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Authors want to thank the civil department in the faculty of Engineering at Al Kufa university and RUDN University for its contribution in supporting this research and assisting in its implementation.</funding-statement><funding-statement xml:lang="ru">Авторы выражают благодарность гражданскому факультету инженерного университета Аль-Куфа и РУДНза их вклад в поддержку этого исследования и за содействие в его реализации.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Akbar M., Budianto E, Doloksaribu B.
