Development of a Reference Energy Mean Emission Level Traffic Noise Models for Bituminous Pavement for Mid-Sized Cities in India

Abstract

Present study is aimed at the development of the Reference Energy Mean Emission Level (REMEL) of vehicle types involved in the mixed traffic flow on the bituminous pavements of Kanpur mid-sized city. REMEL is the basic input parameter for a traffic noise propagation model. Data were collected at five locations in Kanpur urban area under the conditions of free flow traffic, good surface and straight alignment. A total 10700 data sets for 11 vehicle categories (bus, truck, tractor-trailer, light commercial vehicle (LCV), 3-wheeler (auto, Vikram),car, motorcycle, e-rickshaw, bicycle, tricycle and horse driven vehicle) were collected from these locations under IMPRINT India sponsored research project funded by the Ministry of Education (MoE) and Ministry of Housing & Urban Affairs (MOHUA), Govt. of India. Sound Level (Leq) was measured using Type-1 Sound Level Meter (SLM) at a distance of 7.5 meters from the centre of the nearby carriageway for single vehicle pass by event. The vehicular cruising speed was also measured simultaneously. Regression analysis shows that the Leq has good correlation with the vehicular speed for every vehicle category. The study provides an interesting insight to noise emission characteristics of vehicle types for mixed traffic under Indian conditions. © 2022 Internoise 2022 - 51st International Congress and Exposition on Noise Control Engineering.
