The Future of Transportation in the Triangle

The Triangle region, particularly Wake County, is getting growing in population and in the number of cars on the road. Not surprisingly, congestion on the Triangle roads is getting worse. The following graphics, from the Capital Area Metropolitan Planning Organization (CAMPO) Long Range Transportation Plan shows the congestion level of area roads during the evening rush hour. Green lines are free flowing non congested roads. Yellow lines are roads that are approaching congestion. Red lines are congested roads. 

The first graphic is for the base year of 2005:


The next graphic is for the year 2035 assuming that population continues to grow and more than doubles in the 30 years following 2005, and that road improvements are made and that the transit plan is implemented:




Of course, in these graphics it is not possible to identify individual road. But it is easy to notice the increase in yellow and red in the Raleigh area.
From these graphics it is clear that if growth in the area continues, congestion will increase even with new roads and the proposed Wake Transit plan. Of course, on solution is to not grow so much.

Is it OK if I use your graphics on my FB page? I will give credit to this blog and to Campo.

It is certainly ok. The graphics are from p.47 of the 2035 Long Range Transportation Plan, published by the Capital Area Metropolitan Planning Organization and the Durham-Chapel Hill-Carrboro Metropolitan Planning Organization
