USER INSIGHT AND ANALYSIS
“... I need a car because I live 10 miles away and has to send my daughter to pre-school everyday... ... It’s really difficult to find a parking place in downtown, so I just stay in my office all day ... ... I bring my own lunch instead of eating outside because it’s expensive (to eat outside) ...
“... that truck is mine ... sometimes I need to carry big materials for store decorations... I pay 39 dollars a month to park my truck in the Liberty parking garage (two blocks away)... I eat with my friends in the restaurants but it’s really hard to park on this street...
“... I need to come back and forth between the store and school. There is no place that I can park my SUV couple of hours... ... I just put my bike behind and park my car at Forsyth Park and ride on my bike in downtown...
“... My mom gave that car to me ... ... I like to bike when the weather is nice, and put my lunch, and change clothes in my messenger bag. But other than that I need to drive my car in winter and summer... ...

OTHER FACTORS80% of the commuters in U.S. drive by themselves, instead of sharing or car-pooling: INEFFICIENCY OF VEHICLE USE
OTHER FACTORS
GREEN-HOUSE GASES
1/3Petroleum
Consumption
43%
in the U.S., 43% of petroleum is consumed by automobile; while contributing 1/3 of the totoal green-house gases emission: HIGH WELL-TO-WHEEL EMISSION.
REQUIREMENTS & DESIGN PRINCIPLES
Problems Design Principles
Consumption of un-renewable resources; greenhouse emission Electric Drive *
Over-sized vehicles Sized as needed
Low vehicle occupation One vehicle serve more people
* Choose electric drive because of its low well-to –wheel emission comparing with nature gas and ethanol, and low cost of bilding infrastructure compared to hydrogen fuel cell.
