Improve token number 29129 Translation to Portuguese at



<I>Traffic Index</I> is a composite index of time consumed in traffic due to job commute, estimation of time
consumption dissatisfaction, CO<sub>2</sub> consumption estimation in traffic and overall inefficiencies in the traffic system.

<I>Time Index</I> - is an average one way time needed to transport, in minutes.

<I>Time Exp. Index</I> - is an estimation of dissatisfaction due to long commute times. It assumes that the dissatisfaction
of commute times increases exponentially with each minute after one way commute time is longer than 25 minutes.
<I>Inefficiency Index</I> - is an estimation of inefficiencies in the traffic. High inefficiencies are usually caused by the fact that people drive a car
instead of using a public transport or long commute times. I can be used as a traffic component measurement in economies of scale.

<I>CO<sub>2</sub> Emission Index</I> - is an estimation of CO<sub>2</sub> consumption due to traffic time. Measurement unit is
grams for the return trip. To calculate an average estimation of emission in grams for one way commute to work, divide this value
with 2.

Actual formulas to calculate indices are subject to change and at this moment, quite complex empirical formulas are used.
