Title: Predicting the Impact of Intercity Transportation Connections on Spatial Environmental Noise Pollution in Greater Khartoum, 2009
Author: Alredaisy, Samir Mohamed Ali Hassan; Ali,Hassan
Abstract: The traffic noise of public transportation vehicles is part of the general environment problem in urban areas, and controlling traffic noise has become a serious issue for communities. To ensure a high-quality environment, methods for predicting noise emissions are used. This study is based on data for minibuses (MB) with a passenger capacity of 15–25 persons, provided by the Department of Public Transportation and Petroleum of Khartoum Town in 2009, and on fieldwork conducted in June 2009. Josse’s mathematical model for noise prediction is used to examine the influence of intercity transportation connections on levels of noise pollution in Greater Khartoum, which consists of the towns of Khartoum, Omdurman, and Khartoum North. The author contends that because of intercity transportation connections, there are significant geographic differences within the transportation network of Greater Khartoum on levels of noise pollution. Results indicate that MB contribute 69.6 dB on average to the total noise level. These values put Greater Khartoum above the mid-point of the scale typically used to compare levels of noise pollution. This noise level also exceeds the 45 dB recommended as safe for a city by the World Health Organization. Mean noise levels in Khartoum, Omdurman, and Khartoum North were 68.6 dB, 72.5 dB, and 67.7 dB respectively; the calculated F-ratio is 1.79, less than the critical value of 4.46, suggesting that the difference is not statistically significant. However, intercity transportation connections have spawned new transportation lines and changed the existing noise levels on all transportation axes in the three towns. The author proposes a plan to curb noise levels caused by MB in Greater Khartoum
