Are you a person who lives somewhere within 100 miles of Pittsburgh, and leave your house regularly?
If that describes you than I'll assume that you often walk on the street, ride in a private automobile, or use mass transit. In each of those 3 cases the information on Streetlights and Sirens may prove useful to you.
I intend to provide daily updates on local transportation issues such as new highway construction, repair work, and alternate modes of transport, as well as an occasional public policy or economic analysis of a given situation.
Additionally, emergency responders may find information related to the incidents encountered specifically on the highways, such as motor vehicle accidents, the relative safety or danger of particular roads and road types, and incidents where an emergency vehicle was itself involved.
