"Previous Successes"

OLYMPIAD XXIII - 1984

  • Projections of Huge Traffic Jams
  • Images of Stranded Tourists Missing Events
  • Residents "Scared" into Leaving Town
  • Los Angeles Praised
    • "Great Planning!"

San Francisco Earthquake - 1989

  • No Advance Warning
  • Motorists / Congestion Disappeared
  • Diversions Did Not Account for Total
  • "Where Did They All Go??"
  • San Francisco Praised
    • "Great Work!"

"People are Resilient AND Resourceful!"

Speaker Notes: In one, we just scared people away. In the second, people disappeared (not telecommuting, not taking alternate routes, not taking alternate modes,....)but came back as soon as the Bay Bridge opened.

We certainly want to use our TMP strategies, but we want to be cost-effective.

  • Shifts in Work Week Scheduling
  • Major Firms Provided Trans., Telecommuting, etc
  • Truck Traffic Reduced during Peaks
  • Rescheduled Highway Maint.
  • Exclusive Bus Lanes
  • Restricted Parking
  • 24-Hour Ramp Metering
  • Increased Usage of CMS

Slide 3

Study Purpose

Caltrans' Mission - To Improve Mobility Across California

8 of 15 of the Most Congested Cities are in California

Graphic from newspaper showing that eight cities in California are considered the most congested including: Los Angeles, San Fransisco-Oakland, San Diego and Sacramento.

Newspaper article headline reads 'Stuck in Traffic Rut', 'Bay Area Commute Second Worst in Nation'

Caltran worker says, "We must get the most out of the roads we have before building any new ones...well, duh!"

Slide 5

What's the Policy?

Deputy Directive 60 (Eff. 2000)

Caltrans' commitment is to: 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, Encroachment Permits, Maintenance, Special Events, 100% Compliance with varying levels of treatment...

Slide 6

TMP Categories & Strategies

"Blanket" TMP "Minor" TMP (Majority) "Major" TMP (~5% of Projects)

Moving lane closures empty cell empty cell
Portable CMS, FSP, TMT, Off-peak hours Night Work, Portable & Fixed CMS, COZEEP, TMT, HAR, FSP, Gawk Screens.. Public Awareness Campaigns, Fixed CMS, Extended Closures, Moveable Barriers, COZEEP, Detours, Reduced Lane Widths, Website, Helicopter..

Slide 7

Six TMP Strategies

  • Public Information
  • Motorist Information
  • Incident Management
  • Construction Strategies
  • Demand Management
  • Alternate Routes

TMP Costs for one Project were estimated as high as $7,000,000

Slide 8

How Would You Measure the Effectiveness of TMP Strategies?

  • Overall Corridor
  • Public Awareness
  • Motorist Information
  • Incident Management

Traffic Volume Counts, Floating Car Runs, Queue Lengths, Transit Ridership, Video Surveillance ..

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 ..

Slide 9

Measurement of Effectiveness (Cont.)

  • Construction Strategies
  • Demand Management
  • Alternate Routes

Traffic Volume Counts, Floating Car Runs, Queue Lengths, Lane Closures Set / Picked Up on Time ..

Trip Mode Distribution, Park 'n' Ride Lot Usage, Carpooling Surveys, Employer Surveys ..

Traffic Volume Counts Floating Car Runs, Origin/Destination Surveys ..

Slide 10

Example of Corridor Effectiveness Results

District 07

I-10 Long-Life Pavement Project

  • Vehicle Delay
  • Traffic Volumes
  • Length of Queues
  • Safety

Example

Pre-Const. Estimate= 1,000,000 veh-hrs

Actual Delay= 16,000 veh-hrs

Traffic Demand on Interstate 10 was reduced by 57% (from 112,000 to 56,000 veh)

Initial Estimate = 44 miles

Actual Queue Length = 1.9 miles

No collisions or Employee injuries occurred in the Work Zone

Project Characteristics

  • Fast-setting Hydraulic Concrete
  • Closed 2 of 4 Lanes
  • Extended 55-Hour Closures

Speaker Notes: PROJECT -- D7 - "LONG LIFE PAVEMENT AC" - EA# 1384UI ROUTE: I-710 (Long Beach Fwy - from SR 1 to SR 405) -- Start OCT 2002 -- 4.9-km segment

DELAY IF NO TMP IMPLEMENTED

Closures: Ten 55-hour Weekend closures (10PM Fri - 5 AM Mon) - stages 3 through 6 5 weeks NB / 5 weeks SB Fwy closure / Ramp closures full structural sections under OC to meet std. Vert. clearance

Slide 11

Actual Delay in Work Zone With TMP Strategies

District 07

I-10 Long-Life Pavement Project

Example

This line graph compares the projected delay in a work zone to the actual delay of a work zone on a given Saturday and Sunday (by hour). The actual delay during an afternoon rush hour, at it's peak on Saturday, was about 500 veh/hr, while the projected delay for the same time period was about 3400 veh/hr. On Sunday, the actual delay at peak rush hour was about 250 veh/hr, while the projected delay for that same period was almost 1000 veh/hr.

Delay in Minutes Saturday Sunday
Rte 30/ Foothill Blvd. 9 2
Arrow Highway 7 2
Holt Ave 6 5
Mission Blvd 3 2
Detour-Rte 60 Freeway 20 34

Slide 12

But.. WHICH strategies led to these Great Results??

Slide 13

Most Effective Strategies - Public Awareness

"If you drive I-80, you might want to consider an alternate route this morning.."

"Which way should we go today..?"

Use HOV, Bus or Rail

Telecommute ..

Leave Earlier or Later ..

Slide 14

Instead of saying "Bridge Replacement Project" --...

Slogans AND Maps are Good and Easy to Remember..

Slide 15

District 04

Central Freeway Replacement Project

  • 5 -15 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?

Example of a ´Lane Requirement and Hours of Work´ Chart

Slide 17

Effective Construction Strategies (Cont.)

  • Construction Staging
  • 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)
  • Narrow Lane Widths or Use of Shoulders (Peak Period)
  • Moveable Barriers
  • Contraglow ("Crossovers")
  • Contingency Plans (Redundancy)

Slide 22

Lessons Learned

Public Awareness: Most Effective Strategies facilitate Decision-Making by Driving Public to avoid Work Zone

  • Public Awareness
    • Newspapers
    • TV News Spots
  • Advance Signage
    • Before Decision Points
    • On Preceding Weeks / Weekends

Construction Strategies are also very effective

  • Adhere To Lane Req'mt Charts
    • Real-Time Statusing is Needed
    • Penalties for Late Lane Opening
  • Keep Lanes Open
    • Narrow Lane Widths
    • Shoulder Usage during Peak

Speakers Notes: Public Awareness -- Local Papers ets. to Hit Specific Group
Businesses -- Flyers to Hit Large Group

Keep Lanes Open -- vs. Accident Rates..??

Slide 23

Lessons Learned (cont.)

Delay cost to motorists vs. TMP Costs

Consider Other Strategies:

  • Extended Closures vs. Night Closures
    • ("Get in & Stay in -- Get out & Stay out!")
  • Close Coordination w/ Locals (Detours, Signals...)
  • Shorten Contract Time through Incentives

Cost vs. Benefit

  • $$$ on Work Zone Enforcement vs. Benefit ??
  • $$$ on Brochures, Ads, Flyers, vs. Benefit ??
    • (Media Coverage -- no cost for Major Projects)
  • Costs of TMP Strategies vs. Delay costs

Other Issues

  • Truck Restrictions / Closures on Parallel Routes
  • Cumulative Impacts due to Multiple Projects
    • (Combine closures when advantageous)

Speakers Notes: Truck Restrictions -- Narrow Lanes...Parallel Routes -- Obstructing Traffic in/out of state

Slide 24

Recommendations

  • Streamlines TMP Process
    • Blanket / Minor Projects (Standardized Forms)
    • Major Projects (Brief, Standardized Reports)
    • Critical Monitoring Activities - Delay Counts, Runs
