Conclusions
Page 18
§For the Buffalo-Niagara metropolitan area, green routing has the potential to result in significant emissions reductions, with reductions in CO emissions in the range of between 26% to 32%
§
§The corresponding increase in travel time for the case study was in the range of 11% to 35% (e.g. Strategy #4 reduced emissions by 27% at the expense of an 11% increase in travel time)
§
§It is possible to devise strategies that strike a balance between reduced emissions and increased travel times
§
§With targeted market peneration, significant emissions reductions can be achieved at relatively low market penetration values.  Moreover, in that case, the increase in travel time is quite reasonable (e.g. a 40% targeted green routing market penetration yielded 25% reduction in CO emissions at the expense of an 8% increase in travel time).
