Highway traffic noise is a combination of the sounds produced by vehicle engines, exhaust, and tires. Traffic noise is also increased by defective mufflers or other faulty equipment. Conditions, like a steep incline, that causes heavy laboring of vehicle engines, will also increase traffic noise levels. Other factors also complicatethe loudness.

Noise. Noise is considered unwanted sound, particularly when the sound causes annoyance. Noise comes from many sources. One of the most significant sources is from transportation, particularly traffic noise. Highway noise comes from three sources: the engine, the .

Guidelines for Analysis and Abatement of Highway Traffic Noise TxDOT Environmental Affairs Division Page 7 of 31 Type II Project: A Federal or Federal-aid highway project for noise abatement on an existing highway.
For a Type II project to be eligible for Federal-aid funding, TxDOT must develop and. defined by VDOT as 1 dB(A) below the noise abatement criteria. o A substantial noise increase has been defined by VDOT as a 10 dB(A) increase above existing noise levels for all noise-sensitive exterior activity categories.
A 10 dB(A) increase in noise reflects the generally accepted range of a perceived doubling of the Size: 1MB.

THREE-PART APPROACH TO HIGHWAY TRAFFIC NOISE ABATEMENT Effective control of highway traffic noise requires (1) control of land use planning adjacent to highways, (2) quieter vehicles, and (3) when feasible and reasonable, abatement of highway traffic noise for individual projects.
The first component is traditionally an area of local Size: KB. The high cost of conventional highway noise abatement methodology (i.e., free‐standing walls) has made mitigation of many impacted sites economically infeasible.
A solution that may prove more economically reasonable for those sites is the use of strategically planted evergreen vegetation to form a dense barrier between the highway and.
“Procedures for Abatement of Highway Traffic Noise and Construction Noise.” If initial traffic noise impact screening assessments indicate the possibility of future traffic noise impacts, then a Traffic Noise Study will be performed.
A Fundamentals and abatement of highway traffic noise book technical memorandum will be prepared to document the assumptions, data, procedures, results and.
Highway traffic noise abatement shall be considered whenever the design year total predicted noise levels approach or exceed 57 dB(A) Leq(h), or there is a substantial noise increase between Fundamentals and abatement of highway traffic noise book and design year predicted noise levels.
NOISE FUNDAMENTALS. Quantitative information on the effects of airborne noise on people is well-documented. If sufficiently loud, noise may interfere with human activities such as sleep, speech communication, and tasks requiring concentration or coordination.
It may also cause annoyance, hearing damage, and other physiological problems. Noise varies with distance. For example, highway traffic 50 feet away from a receptor (such as a person listening Fundamentals and abatement of highway traffic noise book the noise) typically produces sound levels of approximately 70 dBA.
The same highway noise measures 66 dBA at a distance of feet, assuming soft ground conditions (such as grass). This decrease is known as “drop-off.”File Size: 2MB. noise abatement measures must be considered and implemented where reasonable and feasible. The Michigan Department of Transportation (MDOT) follows all Federal laws, regulations, and guidelines for Type I noise abatement.
Type II, or voluntary, abatement is a proposed federal or federal-aid highway project for noise abatement on an existing. Fundamentals and Abatement of Highway Traffic Noise, Report No.

It represents all five transportation modes: air, highways, public transportation, rail, and water.5/5. If the existing traffic volume on a street is PCE and if the future traffic volume were increased by 50 PCE to a total of PCE, the noise level would increase by dBA.
Similarly, if the future traffic were increased by PCE, or doubled to a total of PCE, the noise level.
