A-1 APPENDIX A MARKET RESEARCH Through widely distributed questionnaire, literature review, and personal interviews; the market research attempted to gather information about customers and the market.

A-2 The questionnaire was distributed to subscribers of the Wyle Email Web Forums and its availability was announced in two newsletters, Airport Noise Report (Vol.

A-3 One respondent suggested that the model would also be useful for projects that are not necessarily multimodal, but where other modes are present, such as a county airport near a highway. In that, the airport is ancillary to the project, but may have an effect on abatement efforts for the highway project.

A-4 Again, the respondents are looking for agencies' approvals for specific uses of the model. Some respondents tempered their suggestions on uses of the model with expressions of concern about the complexity and practicality of bringing the various modes into a single environmental model.

A-5 Some respondents identified the need to assess the effects of alternative fuel types for various mobile sources. One respondent suggested extending the model output to include impacts, such as, number of sleep awakenings and number of people highly annoyed.

A-6 ● Represents the first step in developing a comprehensive community noise model. In the case of a Master Plan project, it could model all sources from a single program to calculate total impacts.

From page 39... ...
A-7 suggests a potential for conflicts across metrics, methods, and fidelity level. Since no one tool addresses all transportation modes, there could be inconsistencies in the results.

From page 40... ...
A-8 One respondent suggested an earlier step that studies existing models and notes similarities and differences in inputs and outputs. Another suggested starting with a GIS database and adding source noise and emissions to it.

A-9 Cost and time are widely shared concerns. Several respondents recognize that this is a very expensive effort.

A-10 ● What data was used and the data sources? ● What were the decisions?

A-11 it is through "guidance" documents. The following paragraphs summarize how various federal agencies address modal noise assessments.

A-12 impact from relevant sources. The assessment also used FRA and FTA vibration impact criteria related to rail transportation.

A-13 motor vehicles, and other sources of emissions common to airports. To comply with FAA requirements, analysts must use the most current version of the model when preparing airport emission inventories and performing a dispersion analysis.

From page 46... ...
A-14 As one of the questionnaire respondents pointed out, there is a need for clearer identification of what types of projects can use such a model. Therefore, to justify the future investment of federal research funds, the MDP proposes a systematic process to gauge the utility of the multimodal model through the use of a market survey firm.
