Abstract

Simulation of urban traffic noise along with a mathematical model of stop-and-go traffic noise for the road network in the city center is presented in this paper. The road network of the central part of Bangkok surrounded by the Cordon line of Rajchadapisek Ring Road was used as the study area. The analysis data consisted of traffic characteristics and its noise levels, which were collected from the study area. The geometrical dimensions of road section at each data collection location also were measured. Characteristics of traffic noise from different types of vehicles were analyzed, including tuk-tuks (motorized tricycle taxis) and motorcycles, which are considered as popular vehicle types in Bangkok. Characteristics of traffic noise levels and data on other traffic noise parameters were used to analyze and subsequently construct the stop-and-go traffic noise simulation model. Finally, the resultant stop-and-go traffic noise models, which are separated into acceleration and deceleration lane models and ...
