MAP-21
Does the travel-time index really reflect performance?
Last week’s release of the Texas A&M Urban Mobility Report, with its charts and lists, prompted the usual flurry of media coverage.

If the index becomes an official performance measure under MAP-21, optimizing system performance could become harder for DOTs.
