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... ...

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.
