The ROC requirement is limited to the coordination and collection of transit information for dissemination to the public. 1. In a 2nd alternative design approach, ROC can assume ISP’s role to collect, coordinate and disseminate transit information to the public. 2. In a 3rd approach, ROC can collect and coordinate transit information and transmits to ISPs for dissemination using ATIS1 and ATIS2.
