It's an Increasingly Dense Jungle Out There: Wisconsin Department of Transportation Travel Time Reliability and Delay Report (Spring 2014)

The report notes:    Many things can adversely aff ect travel time reliability, including (bullet points added)
  • tra ffic incidents, 
  • weather, 
  • special events, 
  • holiday tra ffic and 
  • work zones.
 Reducing or mitigating the impact of these factors serves to improve travel time reliability.  

As I see it, the above list doesn't address the root cause -- too many private vehicles, not enough public transit.

And here's what I see as the biggest roadblock to a sustainable solution.

As we have seen for decades, more highways and additional lanes and exits only serve to encourage more auto traffic, more driving alone.  Until serious efforts are made to change people's long-ingrained driving habits and to provide sufficient funding for public transit, the orange and red lines on the above map are not going to change.  In fact, there will likely be a need to increase their width.
