A research study revealed that, in most cases, once existing highways near urban areas are widened and extended in an attempt to reduce traffic congestion and resulting delays for motorists, these problems actually increase rather than decrease.

"Surprising" Phenomenon
Why do traffic congestion and delay problems increase after widening and extending highways in urban areas?

Objective
The correct answer should suggest a difference between having wider, more extended roads and having less wide, less extended roads. This difference should create the potential for more congestion when roads are wider and more extended.

A
Widened and extended roads tend to attract many more motorists than used them before their improvement.
Wider, more extended roads could lead to more congestion by attracting a lot more drivers. This effect could more than outweigh whatever decrease in congestion the physically wider roads create.
B
Typically, road widening or extension projects are undertaken only after the population near the road in question has increased and then leveled off, leaving a higher average population level.
We’d still expect wider roads to lead to less congestion. Maybe these projects only occur in highly-populated areas; wider roads can still allow people to drive more freely and with less delays.
C
As a general rule, the greater the number of lanes on a given length of highway, the lower the rate of accidents per 100,000 vehicles traveling on it.
It’s not clear how the accident rate relates to congestion and delay.
D
Rural, as compared to urban, traffic usually includes a larger proportion of trucks and vehicles used by farmers.
The discrepancy involves urban areas. A comparison to rural areas doesn’t explain why wider, more extensive roads in urban areas leads to more congestion.
E
Urban traffic generally moves at a slower pace and involves more congestion and delays than rural and suburban traffic.
The discrepancy involves urban areas. A comparison to rural areas doesn’t explain why wider, more extensive roads in urban areas leads to more congestion.
