Evaluating sustainable indicators for urban street network: Al-Najaf network as a case study

Abstract The city of Al-Najaf encounters significant challenges pertaining to traffic congestion within its street network. The aim of this study is to evaluate specific sustainable indictors of Al-Najaf’s main urban roads. The objective of this study is to determine the level of traffic performance, traffic pollution, noise, and public transportation. Field data were gathered using video cameras to measure traffic flow, while portable sound meters measured the accompanying noise levels and air quality detectors and Grey Wolf devices were employed to evaluate pollution emissions. Arc GIS Pro 3.2 has been used for facilitating the required information of road length and point data location. The results indicated that the sustainable indicators such as the level of pollution is up to the unhealthy level. Whereas the average noise level exceeds the acceptable level by 15%. Finally, the indicator of public transportation is remarkably low, as it was noted that there was a complete absence of public transportation, and the percentage of buses was 1%. This study suggests adding a green zone along with the major road in the city.
