“…Environmental noise modeling has the objective to estimate national and local equivalent noise sound pressure levels in terms of L 90 ,L 10 ,L max ,L min and L eq . The result of noise modeling may be used for the development of two-dimensional (2D) and three-dimensional (3D) noise maps which provide information on noise exposure of people [44,45]. Noise monitoring is used to assess critical sound pressure levels in residential, commercial, and industrial areas under different environmental conditions.…”

This chapter describes the challenges of environmental noise policies and governance, noise emissions, noise transmission modeling, and those of health and economic risk assessment in developing countries. It bases on an analysis of current legislation regarding noise pollution in major developing countries in Asia, Africa, and Latin America. Although legislators are engaged in promulgating laws and regulations explicit procedures for noise measurement, noise mapping, development of a healthy and comfortable soundscape, and the implementation and enforcement of legislation are rarely developed. A strategic framework approach is needed to overcome these challenges and enable countries to achieve sustainable environmental noise management. Guidelines are provided to resolve these tasks to better protect the population of urban areas against the health end economic impacts of environmental noise.

“…In [11], equivalent hourly traffic noise levels at different intersections in the city of Doha, Qatar were measured and compared to the local and World Health Organization (WHO) thresholds. Their results showed that regardless of the day (weekday or weekend), the mean 16-h daytime traffic noise levels at all sites exceeded the local and the WHO's recommended thresholds.…”

In this work, sound pressure levels of road traffic on about twenty selected locations in the Agdal District in Rabat City were carried out. The traffic consists mainly of light vehicles with similar characteristics. All measurements were performed in 1/3 octave with an integration step of 20 ms during the period of 15 days from 8 a.m. to 7 p.m. This large amount of data allowed the reconstruction of the spectrograms using a script written in Mathematica language. An interesting result obtained concerns the basic interval required to have a sufficiently representative equivalent level. Indeed, the calculations have shown that about 20 min of measurements are sufficient. This confirms the result already mentioned in our previous work. This result will therefore make it possible to optimize the measurement period during the campaign, in particular for locations where the number of locations is high or the quantity of recordings is large. Frequency analysis revealed spectrum similarities between two locations of different traffic intensities, but of similar composition. This observation is also observed over the different periods of the day (morning, afternoon, evening). In addition, an estimate of the inconvenience felt by local residents was made on the basis of the L den estimated from the measured L 50 . It emerges that, for the majority of the locations subject to the measurements, the percentages of very inconvenienced and inconvenienced people are above 20% and 30% respectively. This result corroborates the results of our previous survey.

“…Traffic congestion is an ongoing problem that leads to noise, air pollution, and energy consumption [1][2][3], and intersection oversaturation is one of the main manifestations of traffic congestion. In the loading, oversaturated operation, and recovery regimes of intersection oversaturation, it is of great significance to accurately identify its regime and cause and combine relevant theories to manage the traffic, which is of great significance for improving levels of service and alleviating or even avoiding oversaturated traffic conditions.…”

With the increase in people’s travel demands, the air pollution generated by the means of transportation they take is also becoming more and more serious. Among them, in the process of people’s travel, the exhaust pollution caused by traffic congestion is particularly serious. Accurately identifying various regimes of oversaturation and taking effective control strategies play a key role in alleviating traffic congestion. There are three regimes of evolution during an oversaturated scenario: loading, oversaturated operation, and recovery. In the traffic signal control under the oversaturated scenario, the corresponding control targets and methods should be adopted based on the regime of oversaturation. In this paper, the multi-objective attributes and their trajectory data of each movement at the intersection are analyzed. Based on the oversaturation severity index, the traffic volume, and the queuing on the movement, the identification and cause analysis of each regime of the oversaturation are carried out. The examples and simulation results proved that the method proposed in this paper could effectively analyze the cause and degree of oversaturation and identify its regime. This has important implications for alleviating traffic congestion and reducing vehicle carbon emissions.
