Noise Pollution at Selected Junctions of Vadodara City from Vehicular Traffic

Noise Pollution at Selected Junctions of Vadodara City from Vehicular Traffic

In India, transportation demand in urban areas continues to increase rapidly as a result of both population growth and changes in travel patterns. During the first decade of the 21st century only, the urban areas in the country confront a historic transportation crisis that has become a planning war against increasing mobility gridlock and noise pollution. Fast growing vehicle population in town in the recent years, has resulted in considerable increase in traffic on roads causing alarming noise pollution, air pollution. Noise level increases with traffic volume in a exponential manner. In India like many other developing countries traffic noise is major continents of environmental pollution and now it has become a permanent part of urban and sub-urban life. It is very harmful to human beings. In the new millennium, for protection environmental degradation it is imperative to pay greater attention towards measuring noise pollution, enforcing regulation for noise emission limits, elimination and control noise pollution.

Urban Noise: A Case Study in Dire-Dawa City, Ethiopia

Urban Noise: A Case Study in Dire-Dawa City, Ethiopia

In this study recording were taken in seven hospitals in Dire-Dawa city including public hospitals, private and one health center. Figure 1 shows that the average noise measured for eight days during morning from 9:00 to 11:00 AM and in the afternoon from 18:00 to 20:00 PM. The major sources are vehicles like bajaj and forces. The minimum average noise recorded near to Dire health center 56.7 dB in the afternoon; whereas the peak noise was recorded in the afternoon near to Delchora Hospital has a magnitude of 86.91 dB. The results we observed during the morning and night are above the recommended limit set by [4]. The results confirm that in all cases near to hospitals the magnitudes of noise levels are high. This will not give comfort for patients in the hospitals, which aggravated their health problems. In most of the areas the noise levels is exorbitant with more than 80 dB average prevailing across the city during both morning and afternoon. This is mainly attributed towards congested traffic area and unplanned construction of hospitals. Most of hospitals were constructed near to the main lines of traffic and they are affected severely by noise pollution. It is considered as the best indicator of physiological and psychological impact on patients and workers within these hospitals.

Scenario of Traffic Noise Pollution and its impact on human health: An Empirical Case Study of Kolkata City

Scenario of Traffic Noise Pollution and its impact on human health: An Empirical Case Study of Kolkata City

The discussion has been surveyed in the various traffic intersection points in the city of Kolkata under the jurisdiction of Kolkata Municipal Corporation which is located at 22 0 30'N to 22 0 40'N latitude and 88 0 15'E to 88 0 20'E longitude and has an area of 187.33 km 2 .After the implementation of auto de-licensing policy most of the people from Kolkata wish to purchase their own personalised branded car, as a result huge congestion could be occurred followed by extreme level of traffic congestion could be observed at the busiest traffic intersection points in the city. According to the data obtained from West Bengal Pollution Control Board, ambient noise measurements have been taken by WBPCB and CPCB at 27 locations across residential, commercial, industrial and silence zones in the city of Kolkata from 1993 onwards. Road traffic noise pollution is also alarming and above the permissible standards in the city in today’s context. However vehicular noise pollution is the predominant cause of noise pollution in the Kolkata city. To understand the situation of noise pollution, eight intersection points of the city have been selected. In northern part of Kolkata four traffic nodeshave been selected because these are busiest traffic sites there followed by in southern Kolkata another four busiest traffic pointshave been selected as monitoring sites. Using the Noise Meter noise data record has been collected during peak and lean hours of a day. The selected survey sites are Ultadanga, B.B.D Bag, Shyambazar, Maniktala from north Kolkata whereas Sealdah, Jadavpur, Gariahat and Rashbehari nodes have selected from south Kolkata as survey sites.

“Noise pollution”: an overview

“Noise pollution”: an overview

Road traffic is the most widespread source of noise in all countries and the most prevalent cause of annoyance and interference. It is directly proportional to the volume of vehicles. Increasing of population is increasing of vehicles and hence increasing of Noise pollution. The major sources of noise in automobiles are exhaust, intake, engine and fan, and tires at high speed. The noise output of all components increases with speed. The Road traffic noise not only depends on volume of vehicles and also depends on several factors; some of them are Road conditions, Traffic clearance, Condition of vehicles, Speed of the vehicle and the people living near roadside (highway) are mainly exposed. For example the study conducted around the main roads inside the urban perimeter of Curitiba, simultaneous measurements were done regarding noise levels, vehicle flow and traffic composition and thus some mathematical models have been developed in order to estimate those sound pressure levels. It was confirmed that people living or working in these areas are exposed to noise levels beyond the legislated norms (Calixto et al., 2003) and the two models for predicting in-city road-traffic noise pollution of Mashhad were obtained by Rahmani et al., (2010).

COMMERCIAL AREAS OFALLAHABAD CITY AND ITS IMPACT ON CONTOUR TRAFFIC NOISE POLLUTION OF THE THE ENVIRONMENT

COMMERCIAL AREAS OFALLAHABAD CITY AND ITS IMPACT ON CONTOUR TRAFFIC NOISE POLLUTION OF THE THE ENVIRONMENT

41 | P a g e roads [5]Generally, motor vehicles, which form a significant part of urban environment, are an important source of noise emission, contributing about 55% of the total urban noise [6]The rapid growth of vehicular population gives rise to unrestrained noise pollution and other associated health problems causing both short term as well as long term psychological and physiological disorders. Traffic can be considered as the major source of noise pollution in large cities [7,8]Depending on its duration and volume of exposure noise pollution effects can be categorized into physical effects (temporary and permanent loss of hearing), physiological effects (high blood pressure, cardiac problem) and psychological effects (sleeplessness, decrease in working efficiency, stress, annoyance etc) [9] Chronic exposure to noise can cause temporary as well as permanent loss of hearing. Besides the auditory effect noise can also cause other significant non auditory health effects, such as cardiovascular problems, hypertension, changes in social behavior and induces depressive tendencies [10] Long-lasting, high- level sounds are the most damaging to hearing and generally the most annoying. Therefore, a study was planned on noise generated from the different commercial areas of Allahabad city and its impact on the people so as to bring down the pollution level through public participation and to suggest mitigation measures.

A  Review on Noise Pollution due to Traffic

A Review on Noise Pollution due to Traffic

Abstract: Noise pollution, in the recent times, has been well recognized as one of the major trepidations that impact the quality of life in urban areas across the globe. India’s major cities are rapidly emerging as industrialized and urbanized cities and have started facing severe noise pollution problems. Noise compared to other types of pollution disrupts daily routine and quality of life. Noise level more than permissible limit, is called noise pollution. It is underrated environmental problem. Every day several vehicles are moving in and around the city resulting in immense heavy traffic congestion and severe noise pollution. Therefore most of the major roads experience huge vehicular congestion during peak hours and it crosses the permissible limit of noise. This paper includes a study on hazardous effects of Noise Pollution and reviews the literature on research carried out in various years and different parts of the world to demonstrate the current status of noise pollution due to traffic.

A study on ambient and traffic noise pollution in Vijayawada, Andhra Pradesh, India

A study on ambient and traffic noise pollution in Vijayawada, Andhra Pradesh, India

Noise is unwanted sound that is harmful, annoying, causes disturbance and may adversely impact the work efficiency and hearing. Increased activities and needs in modern urban life are causing severe noise pollution. Noise pollution due to automobiles is a major source of pollution in urban areas. growing vehicle population in urban regions in the recent years, has resulted in tremendous increase in traffic on roads causing alarming noise pollution, besides air pollution. Traffic noise is affected by factors like traffic volume, vehicle mix, pavement type and vehicle condition (Marathe, 2012). Noise level increases with traffic volume in an exponential manner and depends on several parameters such as source, medium, vehicle speed, road conditions, distance from source etc. (Vilas and Nagarale, 2013, Suhas and Adavi, 2015). Hence, the overall noise is dependent on the characteristics of the vehicle and the relative proportions of the vehicle types included in the flow. People generally hear sounds between the “threshold of hearing” and the “threshold of pain”. In terms of pressure, this is 20 μPa – 20 kPa (Garg, 2014). Noise level is measured in terms of decibels (dB). The Noise levels are measured using a sound level meter and calculated values such as L10

REVIEW ON ROAD TRAFFIC NOISE POLLUTION

REVIEW ON ROAD TRAFFIC NOISE POLLUTION

Abstract: Molecules vibration creates sound and it can pass through any substance whether it is a solid, liquid or gas but vacuum has no molecules, and that’s the reason, the sound cannot travel through. Noise pollution is displeasing human being, animal or machine created sound that disturbs the activity or balance of human and animal life. Due to increasing population and industrialization, the transportation in the city has increased to un-imaginary highs and causes want of efficient mass transfer system. The increased vehicular numbers on existing roads has considerably pushed traffic to create noise that adversely affects the human beings and living creatures. In the present study efforts were made to study the noise levels at different locations by using sound level meter so that the negative aspects of harsh sound can be mitigated. The collected data will be analysed to know the traffic behaviour and characteristics of different roads and location of the Gandhinagar city like hospitals, school, office's and residences etc. and then the maximum noise level will be estimated.

Effect of Road Traffic Noise Pollution in Cuddalore Town: A Case Study

Effect of Road Traffic Noise Pollution in Cuddalore Town: A Case Study

Abstract: The paper suggests that vulnerable institutions like schools and hospitals should be located about 50m away from the roadside unless any special arrangement to alleviate sound is used. Noise measurements were taken at seventeen chosen areas with high population density, heavy traffic, commercial and residential buildings. At each sampling site six readings were taken after an interval of every 45 minutes in June 2012. Average, maximum and minimum values were calculated and compared with standards prescribed by the Central Pollution Control Board. Noise pollution was measured and analyzed and it was noticed that the maximum average of noise level was measured. The major contribution of the traffic noise, towards overall noise pollution scenario, is a well-known established fact. Traffic noise from highways creates problems for surrounding areas, especially when there are high traffic volumes and high speeds. Vehicular traffic noise problem is contributed by various kinds of vehicles like heavy, medium trucks/buses, automobiles and two wheelers. Amongst, noise pollution is an important type, which causes more annoyance and health problems to the human beings. The present work discusses the fundamentals of acoustics and analysis of vehicular traffic noise. The vehicles represent the most important noise source. It was estimated to about 80% from road vehicles. Road traffic noise is one of the most widespread and growing environmental problems in urban areas. The impact of road traffic noise on the community depends on various factors such as road location and design, land use planning measures, building design, vehicle standards and driver behavior. In the study area 17 locations are identified to measure noise level. By using sound level meter noise levels are measured at different peak sessions i.e. morning, afternoon and evening.

An Investigation of Traffic Noise Pollution Effects on Citizens` General and Mental Health (Case Study: Kermanshah City)

An Investigation of Traffic Noise Pollution Effects on Citizens` General and Mental Health (Case Study: Kermanshah City)

Noise pollution psychologically means unpleasant and unwanted sound, and quantitatively is a combination of different sounds with different wave lengths and intensities that not having a clear and certain composition sounds unpleasant to ears (Ahmadzadeh, 1996). Noise is unwanted and bothering sound waves that are produced by frequent changes in the ambient air pressure. Given that exposure to overloud sound can endanger health and generally has negative effects on living creatures, it is considered as one of the environmental pollutions (Makhdoom, 1989). The impacts of sound on human do not usually appear directly and shortly; because, sound has a short-term nature and, therefore, can not remain for a long time in the environment. However, even this short-term durability could have significant impacts on humans and their surrounding environment in the long term. Physiological and mental impacts of sound usually appear gradually on human, and in the long term they will directly affect the nervous system and the consequences of which will show up (Karamkhani, 1996). Mental effects of noise do not have a direct relationship with sound intensity; because, sometimes the lowest sound might cause the most intensive reaction, or the highest sound could have no effect on the human mind; mental effects of noise are different from person to person, situation to situation, and time to time. Nevertheless, on the whole, it could be concluded that noisy environments can mess up communication and understanding abilities, reduce the brain activity, causes incoordination in physical activities, reduce learning abilities, and increase the number of flaws (Ghavam, 1996).

Bus Driver Fatigue Monitoring And Accident Alert System Based On Analysis Of Eye State

Bus Driver Fatigue Monitoring And Accident Alert System Based On Analysis Of Eye State

GPS use satellite data to calculate an accurate position on the earth. These calculations can relate the user‟s position to almost any map projection within milliseconds. All GPS work in a similar manner but they often look very different and have different software. The most significant difference between GPS receivers is the number of satellites they can simultaneously communicate with. Most receivers are described as 12 channels meaning they can communicate with 12 satellites. Older models may be 8 or even 5 channels with more modern receivers capable of communicating with 14 – 20. Given the current (2005) makeup of the GPS satellite‟s constellation 12 channel is more than adequate.

Using Tourism-Based Travel Demand Model to Estimate Traffic Volumes on Low-Volume Roads

Using Tourism-Based Travel Demand Model to Estimate Traffic Volumes on Low-Volume Roads

Rural tourism is a significant part of global tourism industry. All regions around the world have shown increasing tourists in rural areas, with the fastest growth in Europe, Asia, and Americans. This study shows the significance of capturing the tourism-related traffic volumes in rural areas for transportation planning and maintenance. The tourism-based model can be easily incorporated into the existing statewide travel demand model and used for future tourism travel demand prediction. This study also adds to the existing knowledge on the estimation of traffic volumes by travel demand model in rural areas. Previous studies mainly focused on estimating traffic volumes in urban areas and Interstate highways. The model developed in this study can be used to estimate ADT in the rural areas where tourism is a major generator of traffic flow on low-volume roads and not enough traffic counters are installed. The model is recommended to update based on the updated census data from the U.S. Census Bureau and the visitation data from the NPS. The model developed in this study is recommended to be applied by government and tourism agencies in other states or countries when census data and tourism visitation data are available.

Air pollution and DNA methylation: effects of exposure in humans

Air pollution and DNA methylation: effects of exposure in humans

In addition to quantile analysis, other advanced statis- tical methods may improve data quality and provide new insights into the relationship between air pollution and DNAm. As an example, a novel multivariate Bayesian variable selection approach was implemented on an ana- lysis of blood DNAm data from 92 volunteers [59]. In comparison with a conventional Bayesian variable selec- tion approach, which identified DNAm of HLA class II histocompatibility antigen, DR alpha chain ( HLA-DRA ), and IL9 as being associated with mean concentrations of black carbon for the month before each blood draw, the new approach had improved sensitivity and identified HLA-DRA , Fc fragment of IgE receptor Ig, and IL9 in as- sociation with black carbon and IL5 and CCL11 with sulfate concentrations. Advances in the analysis may lead to greater consistency in the results obtained from stud- ies of air pollution and DNAm, given that, as indicated in Additional file 2: Table S2, there is no consistency among the top CpGs identified in the studies reviewed.

The study area (approximately 21 km x 5 km) is across the bay from San Francisco, and includes 10 neighborhood elementary schools that span a busy traffic corridor. The topography is relatively flat and the urban landscape consists primarily of widely spaced, low-level buildings. Traffic congestion in the San Francisco-Oakland area ranks second in the United States,(39) but regional air quality is generally good due to ocean breezes from the southwest or west. At the nearby air quality monitoring station (Fremont), 15 km southeast of the study area, ozone concentrations rarely exceed the national or state standards (0-1days/ year above federal ozone standards for past 3 years). Annual-average concentrations of PM 10 and PM 2.5 at the Fremont station were 23.4 and 12.2 µg/m 3 ,
