Illinois is looking at authorizing automated speed enforcement within "safety zones". They have defined these as follows
an area that is within one-fourth of a
mile from the nearest property line of any facility, area, or
land owned by a park district, school district, community
college district, or public or private college or university
that is used for recreational or educational purposes; provided
that if any portion a roadway is within that radius, the safety
zone also shall include the roadway extended to the furthest
portion of the next furthest intersection.
Is there currently a utility that would allow me to visualize this at a crude level? IE, draw a bubble arround any point or area that had a tags x, y, or z?
Thanks for any references...

Yuck, how on Earth did they come up with such a definition ? Anyway, I don't know much but I'd say your best bet is to get an Illinois extract and run some sql in the db. First select all objects whose tags match a "facility, area, or land..." and put those in a table. Then run another select to retrive all objects within a quarter-mile of the first list. Good luck :)

How: Isn't the legislative process a lovely thing?
Fortunately, it doesn't apply to the entire state. Only to "municipalities with a population of 1,000,000 or more inhabitants".

Bill has been revised to trim the boundary down to 1/8 mile, only during operating hours, and now exclused controlled access highways with 8 or more lanes (and lake shore drive).

Hi Mythdraug,
The bill would interest Portland residents who have pointed out that while Oregon children are protected by 20mph zones near schools, no such protection is offered to elderly residents. Please let me know of the name/number of the proposed legislation so that we may follow from Oregon.

Katie,
The legislation proposed doesn't offer the elderly any protection. It is for automated speed enforcement (think red-light camera for speeding). Causes a non-moving violation to be issued to the registered owner if their vehicle is caught speeding. The safety buffer their edge to say "it's for the protection of children, not revenue generation".
Anyhow, the bill can be found at the following link:
