AOS History May 98
"The Ann Arbor Transportation Authority and its prime contractor, Rockwell introduce the Advanced Operating System, the first fully integrated public transit communication, operation, and maintenance system.
AATA serves over four million passengers per year with 27 bus routes and paratransit service for seniors and people with disabilities in Ann Arbor, Ypsilanti, and adjacent areas. Services are offered 24 hours a day, seven days a week in Ann Arbor. Though national public transit ridership rates are declining, AATA continues to buck the national trend by documenting an increase in ridership on the average of 8 percent each year.
The AOS project began in the fall of 1996, when the prime contract for development and implementation was awarded to Rockwell. Operation of the Automatic Vehicle Location and Computer Aided Dispatch is in its second year of operation. Final system integration testing is being completed and the project completion is scheduled for this summer. Ninety percent of AOS funding is provided by Federal and State grants."
