1 Feb 17, 2005 Talking Operations

2 INITIAL TMPs -- Major Planned Events l OLYMPIAD XXIII TMP mitigated: l Projections of Huge Traffic Jams l Images of Stranded Tourists Missing Events l Residents Scared into Leaving Town CONSTRUCTION progress remained a high priority - Motorist inconvenience was secondary..

3 Travel Info for Motorists was not an organized effort -- Motorists were left to their own resources.. Construction Somewhere Up Ahead CMS located approximately 12 mi. from the bridge. Napa River Bridge Repaving of a bridge approach section at the Napa River Bridge required the nightly closure of the bridge at 9 p.m. each night. Desired route Detour San Francisco Sacramento

4 8 of 15 of the Most Congested Cities are in California Caltrans Mission To Improve Mobility and Safety Across California 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. Construction Motorist Inconvenience

5 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, , FHWA published the final rule on Work Zone Safety and Mobility in the Federal Register on Sep 9, Effective date of Oct 12, 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 URL:

6 FIRST STEPS 1.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 …)

7 TMP PROCESS Conceptual Planning and Design Request TMP Data Sheet What Kind of TMP is required? Establish TMP Team (Ops, Design, Traffic, Const, CHP) START MAJOR Prepare Data Sheet Arrange for Funding of TMP Strategies Detailed Plans & Specs (inc.TMP) Modify Strategies as Needed Start early TMP elements Begin Construction Implement TMP Minor Maintenance and Permits activities Blanket ** Modify TMP Strategies as Needed / Monitor traffic initially / Provide Lessons Learned

Night Work, Portable & Fixed CMS, COZEEP, TMT, HAR, FSP, Gawk Screens.. Categories and Strategies

10 PUBLIC AWARENESS STRATEGIES Leave Earlier or Later.. If you drive I-80, you might want to consider an alternate route or telecommute this morning… Telecommute.. Improve Your Drive on the Five! Slogans are Easy to Remember..

11 What Did the Public Notice? Percentage District 04 Central Freeway Replacement Project Metro Traffic 511 Project Characteristics - Full-freeway Closure - On- and Off-Ramps Closed - Extensive Public Info Campaign Newspaper TV News Freeway Signs Radio Traffic Reports Radio News Reports Word of Mouth Fold-out Brochures Newspaper Ads Newsletters Billboards One-Page Flyers Banners Man in the Street Other Public Meetings

12 - Based on 0 delay (Const.) minutes Delay (Maint.) - According to District Traffic Managers - eliminates about 90% of potential delay PROBLEMS - Const. windows reduced - More Night work (Urban/Rural) - Comparative Quality? - Comparative Safety?

13 Other Construction Strategies (Cont.) CONSTRUCTION STAGINGCONSTRUCTION STAGING DELAY PENALTY -- Hammer for the RE to charge the Contractor ($$$) for late pick-up of the closure.DELAY PENALTY -- Hammer for the RE to charge the Contractor ($$$) for late pick-up of the closure. EXTENDED CLOSURES (e.g. 55-Hour Weekends or 72-Hour Weekdays)EXTENDED CLOSURES (e.g. 55-Hour Weekends or 72-Hour Weekdays) NARROW LANE WIDTHS or USE OF SHOULDERS (PEAK PERIOD)NARROW LANE WIDTHS or USE OF SHOULDERS (PEAK PERIOD) MOVEABLE BARRIERSMOVEABLE BARRIERS CONTRAFLOW (Crossovers)CONTRAFLOW (Crossovers) CONTINGENCY PLANS (Redundancy)CONTINGENCY PLANS (Redundancy)

14 l Traffic Characteristics l Public Awareness l Motorist Information l Incident Management Examples of Performance Measures Personal or Mail-in Surveys, No. of Calls or Website Hits, Public Meeting Attendance.. Personal or Mail-in Surveys, Traffic Observations.. Accident Response / Removal Time, Pre- / Post- Accident Rates.. Traffic Volume Counts, Floating Car Runs, Queue Lengths, Transit Ridership, Video Surveillance..

15 District 08 I-15 Devore Pavement Reconstruction EXTENDED CLOSURE - Schedule, Cost & Delay Comparison Project Characteristics - Pavement Reconstruction - both directions mile segment of I-15 (heavy commute) - Continuous closure Total Closures Closure Hours User Delay Construction Traffic Handling Total 72-Hour Weekday Hour Weekend Roadbed Continuous Hour Night-time 2202, Est. Delay (Min) Construction Scenario 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.

16 How much delay did you experience during the extended closures (SB)? Do you support the Rapid Rehab Approach for future projects? No 25% Yes 75% No 31% Yes 69% Asked During Construction Asked After Construction None 13% 15 min 18% 30 min 22% 45 min 20% 60+ min 27% Others 11% Prefer Night-time or weekend 64% Cancel project 14% Add lane 4% Continuous 7% Negative Public Reaction to 72-hour Weekday Closures (Victorville Public Mtg) District 08 I-15 Devore Pavement Reconstruction
