Summary
This summary is machine-generated.Traffic noise near intersections is a significant urban issue. This study found that while traffic volume, honking, speed, and median width are influential, only traffic volume and honking are necessary conditions impacting noise levels.
Area Of Science
- Environmental Science
- Urban Planning
- Acoustics
Background
- Traffic noise poses a significant challenge for urban populations, particularly in high-traffic areas like intersections.
- Effective management of urban traffic noise requires a deeper understanding of the variables influencing noise levels at intersections.
Purpose Of The Study
- To identify and differentiate the critical factors and necessary conditions that determine specific traffic noise levels at urban intersections.
- To provide actionable insights for policymakers to mitigate traffic noise pollution.
Main Methods
- Utilized 342 hours of field data collected from 19 intersections in Kanpur.
- Employed advanced statistical techniques: Partial Least Square-Structural Equation Modelling (PLS-SEM) and Necessary Condition Analysis (NCA).
Main Results
- Identified traffic volume, honking, speed, and median width as significant factors influencing traffic noise.
- Traffic volume and honking positively correlate with noise levels, while speed and median width show a negative correlation.
- Crucially, only traffic volume and honking were determined to be necessary conditions for achieving specific traffic noise levels.
Conclusions
- Traffic volume and honking are essential drivers of traffic noise at intersections, making them key targets for noise reduction strategies.
- Findings offer valuable data for urban planners and policymakers to develop targeted interventions for controlling intersection noise pollution.

Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...
Friedman's Two-Way Analysis of Variance by Ranks is a nonparametric test designed to identify differences across multiple test attempts when traditional assumptions of normality and equal variances do not apply. Unlike conventional ANOVA, which requires normally distributed data with equal variances, Friedman's test is ideal for ordinal or non-normally distributed data, making it particularly useful for analyzing dependent samples, such as matched subjects over time or repeated measures...
Consider two sources of sound, that may or may not be in phase, emitting waves at a single frequency, and consider the frequencies to be the same.
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
