Portland Makes School Zones/Child Safety Nearly Obsolete

Now that Portland has a 20 mph speed limit in all residential areas unless posted otherwise, it's kind of sad to see school zone warnings to slow down to 20 mph during school days and certain hours or when the school light is flashing. It's now school zone 24/7--which means with no relationship to the safety of children.

I took this photo outside Parkrose High School. Kids are no longer anything special.


I don't mind the slower speed. I'm not in such a hurry as I get older. But, I wonder at the reasoning.

They say reducing 5 mph to to 20 mph will make a big difference. I don't believe it. I bet there won't be significant drop in traffic injuries and fatalities, but there will be a lot more road rage as the vast slice of drivers in a hurry to get somewhere grind their teeth in residential areas.

Hey, if 5 mph makes such a big difference, why is Oregon going to raise truck speeds from 55 to 60 on some highways? Because it doesn't make such a big difference, that's why. Might even reduce accidents as car drivers aren't so frustrated by lower speed truck drivers.

Actually, a significant cause of fatal accidents is speeding which is highly related to age (young), gender (male), alcohol and motorcyles. The "20 is plenty people" have taken none of that into account.

People tend to drive at what they think is a safe speed. Slowing down to 20 in a school zone is made more palatable because one thinks of the increased likelihood of children in that area. Who is going to pay special attention to children's needs and school zones now? Not many and only when the school is on a faster speed street.

Where there isn't a similar increased likelihood of a special needs population in residential areas, it seems that there will be more vehicles ignoring the new law as an unreasonable limitation. From a National Conference of State Legislatures 2014 speed and speed limit report:
One of the most significant areas of state speed legislation in recent years has been raising speed limits. Studies have shown that increasing the speed limit does not necessarily lead to an equivalent increase in driving speed because drivers continue to drive at the rate of speed at which they feel comfortable.
