  2. Traffic Engineering Section • 700+ signals total in AMPA • Bernalillo County 57 signals • Staffing • One Engineer • Two Signal Technicians • Close to 90% of signals are located along major corridors in metro area

  3. Alameda Blvd.

  4. Alameda Boulevard • 17 signals – US 550 to I-25 • Multiple jurisdictions • Rio Rancho  City of Albuquerque (COA)  County  then back to COA • Most congested corridor in AMPA

  5. Hardware • 7 signals in unincorporated area • Twisted pair interconnect, actuated-coordinated closed loop system • TS1 NEMA Cabinets, Econolite Controllers

  6. Bernalillo County Traffic Engineering Section • BC Traffic Engineering Section - Operates 55 signals in the unincorporated areaStaff , Overview of Signal Program

  7. Adaptive Signal Control • Traffic Demand • Directional Peaks & heavy left turn volumes • Unpredictable at times • School Ingress/Egress • Incidents – truck traffic • Very high side street volumes – Rio Grande • Left turn queue spillover • Objectives • Improve Travel Time – peak/off-peak • Recover from pedestrian calls • Future transit priority timing

  8. Adaptive Signal Control – Challenges • Financial Resources, time, effort • Acceptance by signal staff • Acceptance by traveling public • Recurring cost • System failure • Revert to actuated-coordinated plan • Alarms • Interference from adjacent COA system

  9. Systems Engineering • FHWA’s Model Document used to prepare SE Document for the Alameda Corridor • ASCT – benefit potential • Capabilities of existing system • Needs not satisfied  Envisioned system • Identify type of system that would best serve our area • Developed system requirements which were used for specifications. • Verification/Validation process led to development of performance based spec

  10. Systems Engineering (cont.) • Request for Bid (RFB) process using low bid award difficult for adaptive system • SE Model Document more detailed than needed for system we plan to install

  11. Moving Forward • On going satisfaction with system – benefits versus effort to maintain • System complexity, training • System reliability • Public and policy maker acceptance • Bernalillo County Public Works committed to improving traffic flow on the Alameda Corridor with the implementation of adaptive signal control
