摘要: To assist in the development of travel plans, at least one first and second user input mechanism is provided via a graphical interface to user. In response, inputs are received respectively used derive baseline revised parameters, which parameters include environmental impact indication. The including indications, presented interface. Difference values between respective may be determined likewise presented. Furthermore, cost commute time indications similar fashion, i.e., based on inputs, subsequently form estimated carbon emissions.
