Spatial and temporal discrepancy of road noise level in Unaizah City

Abstract

The paper is entitled “Spatial and temporal discrepancy of road noise level in Unaizah City”. It  is concerned with measuring road noise levels in Unaizah, to detect the spatial and temporal variation of its types, relying on DSLM-LA:2851264, GPS, and QGIS to download road data from Open Street Map and represent on maps, in addition to methods for detecting spatial and temporal variation in the study data. It concludes that noise rates on the roads increased, especially during (5 - 7 p.m.), in addition to the spatial and temporal variation in noise rates.

King Abdulaziz Road recorded the highest levels of noise during the working time (12 - 2 p.m.) and quitting time (5 - 7 p.m.). The roads in the city center and the roads in the eastern and southeastern parts; exceeded 80 decibels. The study recommended redesigning the central area roads, paying attention to afforestation, and promoting positive behaviour among road users.
