Way back in 1989, Peter Newman and Jeffrey Kenworthy showed that traffic congestion REDUCES air emissions and gas consumption at the regional level. This is in part due to the reduction in low-value car trips caused by the time tax that congestion imposes.
The compact development pattern that can result from more housing being built in Boulder would reduce the PER CAPITA trips made by car. Since Boulder currently has very low-density, dispersed patterns of development (and WAY too much free parking), per capita car trips are very high.
Boulder is way better off — and is much more affordable and equitable — if the City successfully encourages more compact development patterns through the construction of more housing.
It would mean a lot more Boulder residents can choose to travel by walking, bicycling, or transit.
Environmental quality goes way up when per capita car trips go down. And Boulder will be a much friendlier and happier and healthier place, as healthier, more enjoyable, sociable interaction is much more likely when using transit, when walking, or when bicycling.
Boulder has made a huge tactical error over the past several decades by thinking that minimizing population growth and reducing density was the way to reduce car trips. Instead, that tactic has put too many Boulder residents in cars, made it much more difficult to travel without a car, and has made Boulder a lot less affordable.
