92% of shopping is done within 20 minutes of where someone lives.  Time not distance is the determining factor.

Increased congestion increases the amount of time a trip takes.

4.5 minutes per trip of extra congestion is the tipping point for economic harm.[/quote]

From your citations:  "While higher ADT per freeway lane appears to slow productivity growth, there is no evidence of congestion-induced travel delay impeding productivity growth. Results suggest that the strict policy focus on travel time savings may be misplaced and, instead, better outlooks for managing congestion’s economic drag lie in prioritising the economically most important trips (perhaps through road pricing) or in providing alternative travel capacity to enable access despite congestion."

This is an argument for increasing public transit, PP. [/quote]

ADT is not the metric here.  Congestion is.  While those two different things are connected, higher ADT obviously increases congestion, you are proposing increasing congestion in an attempt to decrease ADT.  Thereby decreasing volume and increasing time distance.  That is a toxic combination.[/quote]

And that research found :[b] "there is no evidence of congestion-induced travel delay impeding productivity growth."[/b]  And also urged other sorts of ways to yes, decrease car trips.  [/quote]

Do you understand what productivity growth means?  It means more output from less input.  In other words less jobs.  The mean goes up but the median goes down.  It's also an aggregate measure that implicitly assumes a single jurisdiction.[/quote]

It also means more output from the same input. Or output that grows faster than inputs grow.[/quote]

It does but in this case we know that job growth went down because it says so.[/quote]
