Given how much Wichitans complain about road construction, it's impressive that the city ranked second-best of 90 cities in fewest traffic delays in the 2009 Urban Mobility Report. Apparently, construction crews are doing a pretty good job keeping traffic moving. The ranking is also impressive given that Wichita isn't doing as well on traffic safety. Wichita dropped 23 positions, to 55th place out of 200, in Allstate Insurance Co.'s annual ranking of the likelihood of having a traffic accident. More accidents usually mean more traffic delays.
