CHICAGO — The suspicions are as common here as snowflakes. Certain people, certain streets, certain neighborhoods seem to get their streets cleared of snow before the rest of the city — or so the whispering has always gone.

But this year, Mayor Rahm Emanuel’s administration will announce on Tuesday, Chicagoans may test their theories about clout on their computers. Using GPS technology, a new city Web site, ChicagoShovels.org, will provide a map of Chicago’s approximately 300 snowplows, making their way in real time through the neighborhoods. Anyone will have a clear view of who gets what first, and whether plows really sweep more rapidly beside the homes of the mayor, powerful aldermen — or even just the neighbor everyone hates.

“If that’s happening, you’ll see it,” Mr. Emanuel’s chief technology officer, John Tolva, said.

The snowplow tracker, which city officials expect to debunk the belief that routes are politically motivated, is but one element of a new computer package focused exclusively on snow — a fact of life in a city that prides itself on its stoic response to winter weather, but was clobbered last year by a blizzard that stranded scores of motorists on a thoroughfare along Lake Michigan.

In part, Mr. Tolva said, the idea to incorporate more technology into the city’s official answer to snow grew out of that blizzard, which dumped more than 21 inches and essentially closed down the city in early February. On their own, residents bonded over shoveling alleys, clearing sidewalks and even being trapped together on Lake Shore Drive, he said, so why not encourage all that bonding in advance online?
