Paradoxed in networks with zero emission links: implications for telecommunications versus transportation

摘要

In this paper, we consider networks in which a link ischaracterized by zero emissions as is typical of networks in whichcertain links correspond to telecommunication links. We identifythree new and distinct paradoxical phenomena that can occur in suchnetworks, which demonstrate that so-alled "improve- ments" to thenetwork may result in increases in total emissions generated. Inparticular, we illustrate, through specific examples, the following:(1)the addition of a link with zero emissions may result in anincrease in total emissions with no change in travel demand, (2)thetotal emissions on a network with a zero emission link may increasewith a decrease in travel of a zero emission link may result in anincrease in total origin/destination(O/D)pair and consisting solelyof a zero emission link may result in an increase in total emissions.
