The Michigan Department of Transportation has been working on projects around the state to ease traffic congestion and has plans for several major projects in coming years, including on the busy U.S. 23 corridor between Brighton and Ann Arbor and along I-94 in Detroit.I can invoke the Law of Peak Expressway Congestion until the second coming of the interurbans, for all the good it does. Adding capacity to the same roads reduces the number of hours in the day during which the road is clogged, without reducing journey-to-work times. Fixing the roads means imposing more hours of congestion and longer trip times on drivers for the duration of the repair project, after which the number of hours in the day that the road is clogged might shrink, and journey times will stay the same.
MDOT spokesman Jeff Cranson said the new funding being discussed for the state’s roads would not be aimed at adding capacity.
But he noted that the money could address traffic congestion through improving poor pavement conditions that can slow down drivers.
The department of transportation in question being Michigan, the possibility of toll highways with differential pricing for heavy trucks doesn't even come up.
