Value/Why Operate or Use a Core?
Efficiencies that enable more self-sustaining business operations.
Customer service that attracts ridership.
 Pricing better matched to demand.
Lower operating and maintenance costs.

Alternatives to Using a Core System
Existing standalone proprietary systems     lack of data integration and the redundant hardware needed make these functions more costly than with a Core System.       Core System, tracking and taking data from vehicles can be scaled far beyond what is possible now because of the minimal incremental cost and independence from hardware or vehicle make.

Current priority systems trigger the next intersection in sight.  Alter signal timing plans in a way that does not aid recovery of signal synchronization.
