Let’s be honest.The posted speed limit on a growing number of residential streets in Manteca is viewed as a minimal speed by way too many drivers.People drive too fast. You could have a dozen police officers canvassing Manteca looking specifically for speeders and still people will exceed the speed limit.Toss in traffic congestion and a growing number of drivers using streets never intended as connectors or they have turned wide connector streets into speedways and you have the ingredients for tragedies.It is why the question needs to be asked: Is it time for Manteca’s elected leaders to start using a four-letter word in the eyes of more than a few Manteca residents? The word is “bulb” as in traffic bulb outs.While speed humps might better address overall speed concerns, traffic bulb outs are much more specific at reducing speed to increase pedestrian safety.Nearby cities — Turlock, Stockton, and Modesto among them — have deployed speed humps to effectively slow down traffic near congested, high-pedestrian areas such as schools as well as to discourage side streets through residential neighborhoods being used as high speed shortcuts.Stockton speed humps in place to substantially enhance safety at August Knodt School where congestion before and after classes can be a nightmare.
