A PERSPECTIVE OF ROAD TRAFFIC NOISE ON JORDANIAN URBAN ROADS

Road traffic noise constitutes a growing environmental problem in Amman, the capital of Jordan. The present and future magnitudes of this problem are evaluated using British Calculation of Road Traffic Noise (CRTN) method. The impact of the problem on the exposed residents is also evaluated through a social attitudinal survey. The results confirm that the present and predicted noise level are high and exceed the maximum allowable limits. The problem has negative impact on daily activities of the exposed residents as about 80% of them report it to affect their sleeping, reading, and rest.

Traffic-Generated Noise Pollution: Public Perception and Modelling Under Jordanian Conditions

Journal of Traffic and Logistics Engineering, 2016

Road traffic noise along the Jordanian road network is drawing an increasing attention due to its growing magnitude and various impacts as a result of the high increase in vehicular traffic. This study investigates the issue with the aim of providing an understanding of its social impact on residents of Amman, the capital of Jordan and developing a noise level prediction model under local conditions. Thirty four sites along urban arterials, representing different characteristics, were included in the study and used for model development. Traffic noise levels were measured at the selected locations and a social survey was performed, using a predesigned questionnaire, to examine the reactions and attitudes of the neighbouring residents towards these levels of traffic noise. The results of the study revealed that the impact of traffic noise on people can cause annoyance while performing daily activities to the extent that 65% of the respondents think of moving to a quitter place, and about 54% were willing to pay for attenuation measures. The resulting prediction model incorporated variables describing traffic and site conditions. The developed model was validated by comparing it's predicted noise levels with those measured and found to be valid under local conditions. 

Observing People's Reactions and Responses to Urban Road Traffic Noise (RTN) in Jordan

Journal of Civil Engineering, Science and Technology

The subjective aspect of assessing Road Traffic Noise (RTN) in urban agglomerations is crucial, as it takes into consideration the sensitivity and specific reactions of residents to Road Traffic noise (RTN) in their living environments. This paper aims to present a detailed sociological study initiated to measure the level of public awareness regarding RTN and estimate the impact of RTN disturbance on RTN disturbance their daily activities. For this purpose, an attitudinal survey was conducted using a predesigned questionnaire with limited noise measurements. The questioners were distributed to the neighboring residents of one of the most congested arterial roads in Amman, Jordan’s capital. The questioner firstly focused on evaluating the awareness of respondents of the problem magnitude and its environmental and health impacts, and secondly, assessing the effects of RTN as perceived by the respondents on different daily activities. The analysis of the collected data found that arou...

Temporal and spatial evaluation of environmental noise in urban area: a case study in Iran

International Journal of Environmental Science and Technology, 2017

Environmental noise pollution is a disrupting factor in the urban areas which can lead to adverse health effects, behavior and quality of life. Present study was carried out in Tabriz (Iran) and aimed to achieve a real condition of noise pollution. Thirty-five measurement stations were selected, and noise levels were recorded. The equivalent noise level in (A) frequency weighting network, route-mean-square sound pressure level, minimum sound pressure level, maximum sound pressure level and noise pollution level were computed as applicable indices. Temporal and spatial variability of these noise indices were plotted by Arc GIS. Public awareness about the noise pollution was assessed through interview. Mixed model and pairwise comparisons were used for comparison of noise indices based on stations and times. It was found that noise levels were significantly different and higher than permissible levels at most stations, especially at heavily travelled crossroads and squares. Mean equivalent noise level for morning, noon, afternoon and night was 71.35 ± 7.49, 71.63 ± 4.90, 70.67 ± 4.52 and 68.74 ± 5.22 dB(A), respectively. The noise indices of all stations and measurement times had significant difference (p value = 0.028 and 0.019, respectively). It was observed that in normal traffic, the highest sound levels are produced by buses, trucks and motorbikes due to low-technology engines. Using the horn was the first reflex of the most drivers. A main part of the noise pollution problem of the studied city can be attributed to driving culture and noncompliance with traffic laws.

Analytical comparison of traffic noise indices—A case study in District 14 of Tehran City

Journal of Low Frequency Noise Vibration and Active Control, 2016

Noise pollution is a growing concern of majority of people around the world. Accordingly, the present study was carried out to analyze, for the first time, traffic noise indices and to introduce an optimal noise index for road traffic noise. For this purpose, the District 14 of Tehran Metropolitan City was selected as a case study wherein a total number of 91 stations were selected so as to cover noise susceptible areas. The measurements were performed at three occasions of morning, noon, and evening. In order to estimate the traffic noise index, noise pollution level, and noise impact index, the L 10 , L 50 , and L 90 , were recorded at each station with 40 replicates. According to the obtained results, among different land uses in the study area, the maximum and minimum traffic noise index values of 113.7 dBA and 50.1 dBA were reported from educational land use. The highest noise pollution level of 96.8 dBA was measured at the educational land use while the lowest noise pollution level of 65 dBA was recorded at the medical land use. The noise impact index value was estimated at 1.5 for the entire region indicating noise level is much higher than the acceptable threshold for residents. Overall, noise pollution level would be a better index when the objective is to measure the overall noise pollution condition in the study area, whereas it gives much more weight to the difference between the ambient and peak noise levels. However, in situations where traffic-induced noise measurement is required, the traffic noise index seems more appropriate. Further, the noise impact index would be more useful to quantify the effect of noise pollution on exposed people.

Assessment of Traffic Noise Pollution in Bukit Mertajam, Malaysia and Erbil City, Iraq

2012

Road traffic noise has become an important factor in societal development. Traffic noise from motor vehicles can inflict serious damage to human health and reduce labor productivity. Traffic noise measurements were taken at two locations: Bukit Mertajam, a developing town in Malaysia, and Erbil City, the regional capital of Iraqi Kurdistan. Field measurements were taken simultaneously with traffic volume measurements in Bukit Mertajam, and then validated using various models. The NAISS model represented the field measurements better than did the other models used. The noise level was higher during peak hours, particularly during evenings when there were increased traffic volumes and a higher percentage of heavy vehicles. The average noise level exceeded the guidelines set by the Malaysian government. The sound pressure levels (SPLs) for Erbil City were higher during mornings, and decreased as distance increased. The correlation coefficient obtained for SPL and the distance between the sound source and receiver indicates a good relationship.
