This shaded part is not a direct ROC requirement, but a future recommendation for the transit agencies for enhanced traveler information and transit operations. 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.
