Mapping Traffic Noise in Kuwait City

Auther : Dr. Dhary S. Al-Kandary - Prof. Jasem M. Al-Awadhi

Objectives: This study mainly aims to firstly predicting the traffic noise level using SoundPLAN 7.1 software, and secondly constructing traffic noise maps for Kuwait City during the daytime, evening, and nighttime periods on weekdays and weekends.
Method: Traffic noise maps were developed using the SoundPLAN 7.1 software and Geographic Information System (GIS) datasets and traffic information. The geo-data sets included ground topography, road design, asphalt type, 3-D building, and weather data sets. For model validation purpose, 24-hour field measurements of noise levels were collected at 13 locations distributed throughout Kuwait City using Casella CEL - 490 Sound Level Meters.
Results: The average percentage difference between field measurements monitored in October 2016 and predicted noise values was 1.9%. Both average predicted and measured noise values (65.1 and 66.2 dB(A), respectively) exceeded the established Kuwait Environmental Public Authority (KEPA) standard of 65 dB(A) under the category of “Traffic- Urban Residential with Commercial Sites” with 27.7% of the total coverage area of Kuwait city. The resulted traffic noise map showed similar spatial patterns for noise levels on weekends and weekdays because of the similarity in the traffic flow direction of the vehicles.
Conclusion: The traffic noise level in Kuwait City exceeds the KEPA national standard limits during all periods of a day on both weekdays and weekends.
