Corridor Design Objectives 1. To reduce cost for providing existing level of service, or 2. To improve the level of service without increasing resources on existing, longer high-frequency corridors Operational Objectives : Increase the operating speed Reduce the vehicle miles of service Reduce unnecessary slack time at terminals Maintain high, uniform vehicle loadings on all segments Issues are: Service Quality Impacts : Changes in wait time, walk distance, and need to transfer Ridership Changes : What ridership changes will result from level of service impacts?
