I used to listen to those channels on a scanner back then. Sometimes you could hear about incidents or conditions before they would make it to the air, or situations in secondary areas (that I happened to be driving in) that weren't considered priority enough to make it to the air.

On 450.112 they mentioned there was a dog running around on the Central Artery at the entrance of the Dewey Sq/South Station tunnel. the report was not aired on any broadcast station, so the only way to get it was to listen to, and repeat what was heard on 450.112, in violation of the Communications Act of 1934.
So armed with recordings of broadcasts from radio stations containing the false information, they went into court and sued Smart Routes and won. I forget exactly what they got in damages.

US District Judge David S. Nelson issued a preliminary injunction last week barring SmartRoute, of Cambridge, from monitoring Metro employees' radio communications.
"While Metro does not have an exclusive right to report traffic information, their two-way radio communications are protected from unauthorized interception," Nelson said in his decision. …
