Orange Line is a SuccessOrange Line is a Success
• 25,000 weekday boardings
• 1/3 of Orange Line customers are new riders to transit
• 77% of Metro customers who previously drove or carpooled indicated reduced travel times
• Safety record has improved significantly

TPS - Bus routes are typically along
the signal timing sync phases of intersections
- The 2070 Controller provides either an early green or late green extension to the sync phase when the bus is behind schedule
- There are more than 26 TPS Routes in LA (1,200+ signals)
