• Comparison of Estimation of Emissions Based on Static and Dynamic Traffic Assignment Models
  Abstract: For the estimation of air quality and noise nuisance often the output of static traffic assignment models is used. However, static traffic model have several limitations related to the realism of dealing with saturated traffic conditions, which are important for the estimation of emissions. Static traffic assignment models predict congestion on the wrong locations and can not deal with traffic flow phenomena like blocking back. As a result also air quality or noise bottlenecks can be predicted on wrong locations, which may lead to erroneous policy decisions concerning new infrastructural measures or implementing mitigating measures on wrong locations. Dynamic traffic assignment models can take these traffic flow phenomena into account and are therefore more suitable to estimate emissions and can in the long term replace the use of static traffic assignment models for larger networks. To provide insights in the differences between estimates based on static and dynamic traffic assignment models in realistic cases, a highway case and urban case are used applying the ARTEMIS model (substances) and AR-INTERIM-CM model (noise). The comparison for both cases shows that large differences are found in the estimates for noise (i.e. > 3 dB(A)) and also for the local estimates of substances (e.g. up to 45% for NOx emissions). When an infrastructural measure is taken the comparison shows that not only the location and extent of effect, but also the direction of effect can be different (i.e. increase versus decrease and vice versa).

• Analysis of Acceptable Flight Frequency in Presence of Effects of Other People’s Noise Situations
  Abstract: Individual maximum acceptable flight frequency (MAFF) in the evening time from 7 p.m. to 10 p.m. was modeled by taking into account the effects of other people’s noise situations. Three classes of low, moderate, and high noise affected zones were designed and used as control variables. Headphone interview system was developed and carried out with 24 Japanese students, all with normal hearing. Information about flight routes and situations of noise-affected zones were given to each subject before answering to the questionnaires. It was found that the individual MAFF will be increased by approximately 1.3 flights if people took into account the situations of high noise affected-zone, all else being held constant. For the moderate noise-affected zone in where individual’s house located, results suggested a reduction of individual MAFF by 2.9 flights. The situation of low noise-affected zone was insignificant. In all, the individual MAFF will be increased by approximately 1.0 flight if people do not consider anyone, ceteris paribus. The methodology used and results from this study may help aviation planner when considering the capacity expansion by which a new flight route is necessarily supplemented.

• Sensitivity of Airport Noise-Damage Costs
  Abstract: To study the relationship between airports and surrounding communities, analysts can use a Noise Depreciation Index (NDI) to describe the percentage change in housing prices associated with a change in noise level, as measured in decibels or some other metric. This paper illuminates the noise-damage cost analytical pathway by conducting a series of sensitivity analyses to identify how changes to NDIs, ambient-noise reference values, and other model inputs affect the noise-damage costs at one airport. These noise-damage costs are analyzed within the context of other community socio-economic indicators, such as income and housing tenure, in order to provide additional context on of the distributional and environmental-equity impacts of airport growth.

• Assessment of Traffic Noise Level Before and After Freeway Widening Using Traffic Microsimulation and a Refined Classic Noise Prediction Method
  Abstract: In this paper, a refined classic noise prediction method based on the VISSIM and FHWA noise prediction model is formulated to analyze the sound level contributed by traffic on the Nanjing Lukou airport connecting freeway before and after widening. The aim of this research is to (i) assess the traffic noise impact on the Nanjing University of Aeronautics and Astronautics (NUAA) campus before and after freeway widening, (ii) compare the prediction results with field data to test the accuracy of this method, (iii) analyze the relationship between traffic characteristics and sound level. The results indicate that the mean difference between model predictions and field measurements is acceptable. The traffic composition impact study indicates that buses (including mid-sized trucks) and heavy goods vehicles contribute a significant proportion of total noise power despite their low traffic volume. In addition, speed analysis offers an explanation for the minor differences in noise level across time periods. Future work will aim at reducing model error, by focusing on noise barrier analysis using the FEM/BEM method and modifying the vehicle noise emission equation by conducting field experimentation.
