Making cycling and walking safe, convenient and fun in Delaware

13 Years Later, An Updated Bicycle Facilities Design Guide from AASHTO

After waiting 13 years, it was not unreasonable to think that an updated AASHTO bicycle facilities guide might explicitly include cycle tracks.  Nope.  But the new guide (officially released in May) represents some modest progress in a couple of places.  An excellent video on the subject can be found HERE.

  T. Coleman Dupont’s Original Concept of the Dupont Parkway   US 13 Northbound into Dover   There are no places in Delaware more hostile to bicycling than certain segments of the Dupont highway (e.g. Hare’s Corner in New Castle).  But 100 years ago, when T. Coleman Dupont proposed building a new road to connect…

If the only tool we have is a hammer, we’ll tend to see every problem as a nail

If the only tool we have for solving transportation problems is “levels of service” (LOS), then we will tend to see every problem in terms of congestion.  As Gary Toth from the Project for Public Spaces notes in a recent article, however, you can “solve” congestion problems by focusing exclusively on levels of service but…

Pretending it is 1952

by Chuck Marohn Cross-posted in Strong Towns The American Society of Civil Engineers has just released a report that should be titled, “Pretending it is 1952.” Like a broken record, ASCE is again painting a bleak picture of the future if American politicians — as if they need to be plied — won’t open up…

Can a Stroad Ever Be a “Complete Street”?

“Complete Streets” is a phrase to conjure with.  The idea that streets are places that should serve many users (and not just car and truck traffic level-of-service) is enormously popular.  And, indeed,  Delaware has an official policy that is called “Complete Streets”.  In reality, however, Delaware’s actual policy is more accurately described as a “routine…

We Have Too Many Stroads

by Chuck Marohn Cross-posted in Strong Towns Americans do not understand the difference between a road and a street. Roads move people between places while streets provide a framework for capturing value within a place. The value of a road is in the speed and efficiency that it provides for movement between places. Anything that is…

Do Conversations Like This Still Happen in 2011?

Wider. Straighter. Smoother. Faster.

Originally published: August 31, 2011 Level-of-Service OK, here at Bike Delaware World Headquarters, we love jargon. And one of our favorite pieces of jargon is “level-of-service” (LOS) which refers to the typical delays experienced by cars at a particular place. For example, the mecca of traffic engineering, level-of-service A: (Wikipedia): Level-of-Service A describes free-flow operations.…
