INITIAL TMP’s INITIAL TMP’s -- Major Planned Events-- Major Planned Events
OLYMPIAD XXIII - 1984 -- TMP mitigated:
Projections of Huge Traffic Jams Images of Stranded Tourists Missing Events Residents “Scared” into Leaving Town
CONSTRUCTION progress remained a high priority - Motorist inconvenience was secondary..
Travel Info for Motorists was not an organized effort -- Motorists were left to their own resources ..

Objective: Minimize motorist delays for ALL activities on the State highway system without compromising public or worker safety, or the quality of the work being performed.

• Key featuresKey features
– A policy based approach to institutionalize work zone processes and procedures, and
– Emphasis on both the broader safety and mobility impacts of work zones
• How it worksHow it works
– Advance work zone considerations as early as possible in project delivery
– Adopt policy and procedures to support systematic consideration and management of work zone impacts
– Develop and implement strategies to manage impacts
– Monitor and assess work zone performance
– Use work zone safety and mobility data to improve policy, processes and procedures
• FHWA support effortsFHWA support efforts
– Develop and provide implementation guidance that addresses every aspect of the new rule by summer 2005
– Contact: Scott Battles, FHWA Office of Operations, 202-366-4372, Contact: Scott Battles, FHWA Office of Operations, 202-366-4372, [email protected]@fhwa.dot.gov
FHWA published the final rule on Work Zone Safety and Mobility in the Federal Register on Sep 9, 2004 -- Effective date of Oct 12, 2007. -- New Rule will affect all State and local governments that receive Federal-Aid Highway funding. -- Purpose of the update is to address the changing times of more traffic, more congestion, greater safety issues, and more work zones

FIRST FIRST STEPSSTEPS1. WE SET UP TWO NEW POSITIONS
• TMP Manager (each of 12 Districts)
• District Traffic Manager (each District)
• WE DEVELOPED TMP GUIDELINES
• WE SET UP A STATEWIDE TMP TRAINING PROGRAM for all involved:
• Traffic Operations
• Project Management
• Design
• Construction
• Maintenance
• We improved coordination by working through our Transportation Management Centers - the Communications “hub” (CMS, Lane Closure …)

Schedule Comparison Cost Comparison ($Millions)
Construction took ONE MONTH instead of eight, and cost $16 million instead of $22 million. It also put down concrete that will last 30 YEARS instead of 15.
Even commuters who were inconvenienced by traffic tie-ups are telling Caltrans in an online survey that they'd support the approach on future freeway projects, versus traditional nighttime-only closures that take months longer and result in inferior concrete.
How much delay did you experience during the extended closures (SB)?
Do you support the “Rapid Rehab” Approach for future projects?

• PUBLIC AWARENESS • Newspapers and TV spots (“low-cost”)• Traffic Reporting Services
• ADVANCE SIGNAGE • Before Decision Point / Monitor Route • Test on Preceding Week/Weekend
• ADHERE TO LANE REQ’MT CHARTS • Use Updated Charts / Volumes on shelved projects• New Lane Closure System assists in providing Real-Time conditions
• KEEP LANES OPEN• Narrow Lane Widths / Shoulder Use• Night versus Day Closures? • Extended Closures?

• MONITOR & DEBRIEF PROJ ENGR AFTER CONSTRUCTION
• TMP TRAINING goes a long way • Train all participants• Educate re: Traffic Ops Role - improves coordination
• UPDATE TRAFFIC PROJECTIONS
• Recheck Volumes for “Benched” projects before Bid• Check for other changed conditions (e.g. new shopping mall)
• STREAMLINE TMP PROCESS (“Cookbook” method)
• Blanket / Minor Projects (Standardized Forms)• Major Projects (More strategies!.. Public info blitz)
• INCLUDE $$ FOR MONITORING• Delay Runs to determine inconvenience to motorists• Traffic counts of main segments AND possible detours
