The term CAB ALTERNATIVES refers to two types of alternative transportation: ELS (Electric Light Shuttle) and ZINS (Zero-Emission Neighborhood Shuttle). ELS is a type of electric vehicle that is used for short trips, such as those within a city or town. ZINS are zero-emission shuttles that are designed to provide transportation in neighborhoods and other areas with limited access to public transportation. Both of these alternatives offer an environmentally friendly way to get around without the need for a car.
