I used to live there. I hadn't heard about this loss, but if it's the schools I'm thinking, the open fields are either active farms, or used to have a church when those schools were built. The speed limits are reduced to 20 during school crossing hours. The schools were both built when Syracuse had fewer than 5000 residents and no need for major arteries.
I don't get it, how does your post rebut the article? It talks neither about the fields nor the school construction (that was the parent poster), and it specifically says that posting a speed limit is not enough as a deterrent.
It's not meant as a direct rebuttal because the article is so far off it isn't even wrong, due to a lack of context around the town's history, and it completely ignores the schooltime 20mph speed limit posted with big flashing signs and enforced by city police. Those schools were both built years or decades before the city even had its first stoplight, long before the other 90% of safe neighborhood streets even existed. There were only farms on a one-mile grid system in most of the city.
Then over time developers built neighborhoods and the population exploded, so as the population grew the roads had to be expanded. Traffic planners had to move people somewhere, and they compensated for the wide streets with 20mph school speed limits, volunteer crossing guards, extensive education of children and drivers, and regular active enforcement of the school speed.
So the article comes across as clueless, seemingly almost deliberately so to exploit a tragedy.
I don't understand the relevance of the town's history. Either the crossing is safe, or it isn't. The history may explain why it's unsafe, but it can never be a justification. That there's some reason behind the configuration is not something that must be pointed out - it's obvious that nobody chooses the locations of streets and schools by throwing darts at a panel. What the author is saying is that the situation is not acceptable - however it may have originated.
As for the 20mph speed limit - besides the fact that he specifically says they are irrelevant, since drivers don't respect them -, how would that have helped, considering it was 8:30pm when the accident happened? And I'm betting the "volunteer crossing guards" weren't around either. Apparently kids sometimes leave schools outside "schooltime" - who'd a thunk it.
Finally, if we're talking about what he left out - maybe you should add the other detail he didn't mention: that there had been already 15 accidents in the crosswalk in question in the last five years. So maybe it should have been clear by now that the methods weren't working.
(By the way, "the population exploded and the streets had to be expanded" is false. Governments have tools to control the growth of the population, like permits and zoning.)
The article is blaming all the wrong factors.
