Slide 1: Los Angeles County Metropolitan Transportation Authority (Metro)
Metro’s Countywide Signal Priority Program
T3 Webinar
January 22, 2008
Slide 2: Background
In the late 90’s, Metro funded several transit signal priority demonstrations
- City of Los Angeles
- City of Glendale
- City of Lancaster
- City of Santa Monica
- Metro
Slide 3: Metro’s Bus Signal Priority Pilot Project
Slide 4: Los Angeles County
- 89 jurisdictions
- 43 public agencies providing fixed route bus service
- Metro alone operates 191 bus routes with over 1.3 million weekday boardings on average
[Map of Los Angeles County and its 89 jurisdictions.]
Slide 5: Program Context, cont’d
Los Angeles County
- 1,433 square miles in Metro service area
- City of Los Angeles = 466 sq. miles
- 88 other jurisdictions = 967 sq. miles
- Over 10,000 traffic signals

Slide 6: Program Funding
- Local
- Proposition C: ½-cent sales tax used to maintain, improve and expand public transit as well as reduce congestion and increase mobility in LA County
- Federal
- Congestion Mitigation and Air Quality (CMAQ) funds through FTA
[Pie chart that shows transit funding stems from two sources: local (Proposition ) and Federal (CMAQ funds through FTA).]
Slide 7: Program Funding
- Bus Signal Priority Pilot Project: $4.3 million
- Metro Rapid Countywide Signal Priority Expansion
- Phase 1: $7.5 million
- Phase 2: $8.7 million (estimate)
Slide 8: Study Tour
Locations
- Portland Tri-Met
- KITSAP Transit
- King County Metro
[Map that shows location of study tours.]
Slide 9: Study Tour Objectives
- Evaluate different signal priority technology solutions implemented by various transit properties
- Study the institutional, political, legal, and financial issues
- Assess systems integration complexities
- Review adopted signal priority implementation guidelines
- Discuss "lessons learned"
Slide 10: King County Metro Transit Peer Review
- Multiple jurisdictions
- Several different traffic signal control hardware types
- Multiple firmware interfaces
- Decision to grant priority made at the local control level
- Headway intervals were similar to ours
- Local traffic engineering control
Slide 11: Countywide Signal Priority Pilot Project
- Crenshaw Corridor
- 10.5 miles
- Adams Blvd. to Redondo Beach Blvd.
- 54 Signalized Intersections
- 51 signal-priority- equipped
- Jurisdictional Partners
- City of Los Angeles
- City of Inglewood
- County of Los Angeles
- Unincorporated County areas, City of Gardena and City of Hawthorne
[Map that shows location of the Crenshaw Corridor.

Slide 12: Countywide Signal Priority Evaluation Results
- Average Bus Travel Time
- Up to 8.8% reduction - northbound PM peak
- Up to 4.2% reduction - southbound AM peak
- Average Delay Due to Red Signals
- Up to 22.5% reduction - northbound PM peak
- Up to 12.5% reduction - southbound AM peak

Slide 13: Countywide Signal Priority Process
[Image that shows Bus-to-Intersection Communications. Communications flows from the vehicle” to the decision to request priority (DTRP) [both on-bus system functions] onto decision to grant priority (DTRP) and implement priority (both traffic signal controller functions).

Slide 25: Multijurisdictional Project Implementation: Challenges and Lessons Learned
- Project Oversight and Coordination
- Allocation of necessary staff resources
- Project schedule to accommodate jurisdictional coordination Issues
- Consensus Building
- Schedule/time management
- No "One size fits all" approach
- Management, administrative, and technical staff must all be included in the decision making process
- Work with your jurisdictional partners both collectively and individually to resolve implementation questions and concerns
Slide 26: Multijurisdictional Project Implementation: Challenges and Lessons Learned
- Legal Agreements
- Respective legal counsels and technical staff must coordinate with one another to address legal concerns
- Project scope, roles and responsibilities, on-going operations and maintenance, cooperation, communications, and liability are key elements
- Legal impasse can become a showstopper
- Corridor Synchronization
- Signal timing update
Slide 27: Multijurisdictional Project Implementation: Challenges and Lessons Learned
- Technology Migration
- Work with participating jurisdictions to ensure system- upgrade compatibility
- Develop an operations and maintenance plan that accommodates potential hardware and software upgrades
- Continually evaluate the existing system and look for opportunities to improve performance
