Transcription

1 PennDOT District 6-0 Signal Retiming Initiative The Route 611 Story Presented By David Adams, PE PennDOT District 6-0 John Albeck, PE, PTOE Albeck Gerken, Inc.

2 PennDOT District 6-0

3 PennDOT Ownership by District

4 PennDOT District 6-0 4,008,994 estimated population in 2010 Census Approximately 32% of state population 3,600 state roadway miles Over 6,000 traffic signals Approximately half of traffic signals in Pennsylvania

5 Traffic Signals in Pennsylvania Signals are owned, operated, and maintained by local municipalities PennDOT acts as a permitting agency Projects types include: - State contract project - Highway occupancy permit - Municipal

6 Closed Loop Systems Closed loop systems gradually installed over past 15 years Currently 1483 signals enabled with remote communications Central server systems more common over past 5 years Extensive fiber backbone utilizing OTN Sonet network

7 Communications Network

8 What s the Problem? Varying levels of expertise on initial timing development Counts old by the time of implementation Engineering services not funded to optimize system in the street Varying levels of system monitoring and maintenance

9 Signal Retiming Initiative Started through DVRPC and PennDOT Central Office Additional collaboration through PennDOT District 6-0 and Counties Funded as a TIP line item with CMAQ funds Open-Ended Contract FY 13-14, $350,000 FY 15-16, $350,000

10 Project Team

11 Retiming Process Select Corridor Stakeholders Meeting and Coordination Throughout Process Memorandum of Understanding and Concept of Operations Before Study Rapid Field Assessment Implementation Analysis, Recommendations After Study Performance Evaluation

12 Project Goals Reduce Travel Time and Delay Efficient Use of Taxpayer Resources Team implements times Do not burden Municipality with additional maintenance Educate Municipal Satisfaction Help identify future enhancements

17 SR 0611-Q01 State Contract Project Cheltenham, Abington, Upper Moreland, Horsham Designer: McMahon Associates $4.3 Million Construction Project Contractor: Lenni Electric Corporation Supplier: Signal Service, Inc. (Naztec) Notice to Proceed: November 2005 Completed: November 2009

18 County Jump Start Project Jenkintown Designer: Pennoni Associates $633k Construction Project Contractor: Armour & Sons Electric Supplier: Signal Service, Inc. (Naztec) Notice to Proceed: April 2010 Completed: October 2010

19 System Controllers NEMA TS2, Type 2 controllers Naztec Model 980 local controllers Naztec Model 981 master/local controllers

20 System Controllers

21 System Communications Spread spectrum radio utilized south of 611/Maryland and on 263 spur Fiber optic cable from 611/Maryland on north into Horsham Master located in each municipality Master broadcasts date/time every 255 seconds GPS Time Clock at each master 59 Signals
