This study establishes the baseline air and noise emissions for Santa Monica before the implementation of shuttle service. The report consists of an Introduction, a section describing Santa Monica, a section on Air Emissions, a section on Noise Emissions, a Results section, a Conclusions and Recommendations section, and a References section. All input data for the air and noise emissions prediction models are presented in Appendix A, and all outputs for the air emissions prediction model are presented in Appendix B.
