Applicability of models to estimate traffic noise for urban roads
BACKGROUND Traffic noise is a highly relevant environmental impact in cities. Models to estimate traffic noise, in turn, can be useful tools to guide mitigation measures. In this paper, the applicability of models to estimate noise levels produced by a continuous flow of vehicles on urban roads is investigated. The aim is to identify which models are more appropriate to estimate traffic noise i...
متن کاملTraffic Noise Annoyance on Roads (tnar)
Noise is known as one of the most frequently reported negative environmental effects of traffic. At present, according to the current standards and calculation specifications, the impact of road traffic noise is represented by the A-weighted energy-equivalent sound level (LA,eq). This quantity does not account for the subjective annoyance of sound events as it is perceived by the affected perso...
متن کاملIntegrated Safety Speed Model for Curved Roads
Statistical data of P.R. China indicate that traffic accidents on curved roads take a large proportion of the total road accidents. To improve safety and driving comfort on curved roads, a mathematic speed model is developed to determine an optimised safety speed on curved roads. The model takes quantitative static road environment parameters (such as curvature, road gradient, superelevation, r...
متن کاملA Review of Traffic Noise Predictive Models
In the traffic noise investigation framework, the need for a suitable predictive model is quite important, since it allows to evaluate the environmental impact, in case of existing infrastructures, or to design the road network such that noise is minimized, if the infrastructures are going to be built. The traffic noise produced by motor vehicles, as main sources in urban areas, is part of gene...
متن کاملConservation law models for traffic flow on a network of roads
The paper develops a model of traffic flow near an intersection, where drivers seeking to enter a congested road wait in a buffer of limited capacity. Initial data comprise the vehicle density on each road, together with the percentage of drivers approaching the intersection who wish to turn into each of the outgoing roads. If the queue sizes within the buffer are known, then the initial-bounda...
