additionally, there are nationally vetted studies that show bike lanes both reduce wrong way cycing AND decrease sidewalk riding at intersections (Hunter), and strong correlations between bike infrastructure and indexed reduction in accident rates, all the while increasing cycling participation in communities. (everywhere)
moving on, perhpas we can get back to the OP:
bike lane widths built to code are recommended minimiums, the AASHTO Green Book encourages more width if there is significant bike traffic. with strong bike advocacy in your community you could work to better accomodate cyclists on these arterials with additional width in the bike lane.
