What was the goal of this effort, anyway? To look good in a "bike friendly cities" rating or to actually accomplish positive change?
Anyway, Plano now has signs that tell riders that quiet residential streets are nice for bike riding. No further comment about that.
Even a cursory look shows the scheme has:
no crossing of Central north of Park (among other things, this makes a ride to Plano East Senior High School 4x~5x longer for many of the students)
no route to Plano Senior High School
no crossing of 121 east of Rasor
no crossing of Bush east of Independence
very few routes to the intersection of the major thoroughfares - which is where ~90% of the retail is in Plano
no route to the city's convention center
no route to the city's principle light rail and bus station on Archerwood
no route to the city's college campus
A bike transportation scheme that doesn't go to the high school or college in town - really?
