Traffic is often times cited as one of the leading disamenities in urban areas. However, it has been shown that adding more lanes in freeways has a negative effect on the overall traffic levels. Why is this the case?
The extra lanes mean more automobile pollution in the area creating more smog.
The extra lanes make traffic flow faster meaning more deaths when crashes do occur on highways.
The extra lanes create a sense of counter urbanization creating more people to leave the urban zones.
The extra lane makes areas more accessible actually creating more traffic on the highways.
The extra lanes do not offer merging options creating longer distances traveled by commuters.
