Trimet Study: Higher density = More cars on the road (more congestion)
Oregonian, September 25, 2007:
If the Eastside Streetcar is built, about 4,537 housing units would be added along the route, compared with 1,105 without it,
Residents in such dense neighborhoods travel an average of 9.8 miles a day by car, less than half the 21.8 miles a day for Portland-area suburbanites. By driving less, they reduce roadway congestion, pollution and greenhouse gas emissions.
Lets Look Closer:
Low density......1,105 units x 21.8 miles/day = 24,089 total miles/day.
High Density....4,537 units x 9.8 miles/day = 44,462 total miles/day, about double the total driving on the same streets.
It appears that density does reduce driving, but not enough to compensate for the increased number of people the result is increased congestion since there is more travel on the same streets..
