The effects of greenhouse gases (GHGs) on global warming and climate change have become increasingly evident, and the transportation sector is a dominant contributor to GHG emissions which responsible for 13% of the world’s total GHG emissions and more than 21% of overall energy-related CO2 emissions. Cities need sustainable transportation system that integrate new technologies and strategies to provide efficient and effective transit service while reducing its GHG emission and improving its livability. This paper explores a suitable and sustainable transportation scenario for San Francisco to achieve its 2035 goal which is to reduce 1,767,500 metric tons GHG emissions annually. There are three major initiatives in this “Walking, Bicycling and Transit City” scenario, which includes practical non-vehicle transit, large capacity low-carbon public transit, and green vehicle alternative to satisfy the city’s need of mobility while minimizing the impact to the environment. The bike and bus rapid transit integrates the bicycle and bus transit systems to provide efficient and effective public transport service to the city. The public electric vehicle sharing program associated with vehicle to grid technology to replace existing internal combustion vehicles, reduce GHG emissions, lower congestion, as well as maintains people’s need for special mobility. And the smart transportation system integrates new technologies to assist travelers to improve travel safety and travel efficiency.
