Abstract

This study analyzes the speed of traffic on city streets and the level of noise from vehicles. In terms of objects: To determine the amount of traffic and the level of noise on Nurafshan and Nukus streets in Tashkent, the intensity of traffic during peak hours was studied. Based on the results of in-kind experiments, the following conclusions were drawn: Despite the increasing density of the road network in Tashkent, the level of congestion on these streets is very high (more than 2400 cars / hour on each side). More than 95% of moving vehicles are cars. The level of noise from vehicles along the construction line on these streets is 18-20 DBa above the sanitary norm in the morning rush hour. This study analyzes the speed of traffic on city streets and the level of noise from vehicles. At the same time, the problem of density of the street network in Tashkent, the results of its comparison with the density in some cities of developed countries.

Highlights

As a result of urbanization in large cities, the demand for public and private transport is growing, along with a sharp increase in population
Despite the fact that Tashkent is a relatively new city - many of the requirements of urban planning are formed in accordance with current standards, today there is a sharp increase in the number of vehicles in the city, including traffic, pedestrian crossings, parking, garages and private cars. as a result, the level of pollution of the city's sanitary condition from traffic noise is a separate issue
The indicator of road network (RN) density in urban planning depends on another important factor, which is the nonlinearity coefficient (Кn) of RN

Summary

Introduction

As a result of urbanization in large cities, the demand for public and private transport is growing, along with a sharp increase in population. A number of economic, social, environmental, sanitary and hygienic conditions are aggravated, such as reduced traffic capacity, reduced traffic speeds, traffic jams at many single-level intersections, lost passenger time, as well as increased emissions and traffic noise. As a result, the level of pollution of the city's sanitary condition from traffic noise is a separate issue. For this purpose, in this case, the data obtained on the basis of the results of in-kind observations of changes in traffic in some streets of Tashkent for the last 3 years (2018-2021).
