Bus TSP System Timeline

2005Rapid 522•50+ intersectionsusing loops

2008Rapid 522•40+ intersections using GPS

2010Rapid 522•Conversion of 50+ using GPS

2016Limited 323•36 intersections using GPS

2016Rapid 522•8 intersections using GPS

Total Current Locations: 138

10-20% Travel Time Savings10-20% Increased Ridership

Light Rail TSP System Timeline

1987•First constructed using loops

•Mainly pre-emptive

1999• Implemented early TSP principles

2008• Implemented modern TSP

2018•Conversion of 97 intersections from loops to GPS

Total Current Locations: 97

Why Integrate Performance Monitoring? Ability to Cross Query

• Patterns in data

• Failure points

• Relationships

Management

• Processing and notification

• Tracking

20

Lessons Learned

Less Reactive More Proactive

• Stakeholders Concerns:

• Difficult to Pin Point Issue:

21

Next Steps

• Continue Stakeholder Outreach

• Build a Common Repository for Data

• Seek Funding and Staff Resources
