Meeting the Customers Needs for

Mobility Safety During Construction
Maintenance Operations
4
It is the sense of Congress that many highway
projects are carried out in a way which
unnecessarily disrupts traffic flow during
construction and that methods need to be adopted
to eliminate or reduce these disruptions.
Section 1090 ISTEA
5
NQI Survey
  • Only 29 of respondents were satisfied with
    traffic flow through Work Zones
  • The other 71 werent!

6
The public is not satisfied with the status quo.
Theyre tired of the way weve always done it.

Safety
  • WZ Fatalities/Injuries (1996)
  • 719 fatalities
  • 133 worker fatalities
  • 37,000 injuries
  • NHTSAs FARS data

8
Delay in WZs
  • Motorist
  • No quantifiable statistics on an areawide or
    statewide basis
  • Economic losses
  • No quantified data on a national or regional basis

9
Meets Three of FHWAs Strategic Goals
  • Mobility
  • Safety
  • Productivity

10
Our Vision
  • "No Delays and No Crashes in Work Zones."

11
Organizations Scanned
  • 26 State DOTs
  • 4 Cities
  • 2 Counties
  • 7 Contractor Associations
  • 3 Equipment Manufacturers
  • 5 Toll Authorities
  • Others (State Police, GHSRs, AAA,


    Trucking Associations, etc.)

12
Expectations of FHWA
  • Technology Sharing
  • Public Education
  • Continuous Quality Improvement
  • Coordinate Research
  • Standardization
  • Partnerships

13
FHWAs Review of WZs
  • State of the practice
  • State of the art
  • Model traffic management program
  • Benchmark our future actions
  • Best practices/policies (250)
  • Menu of practical measures

14
Why Do We Need To Change?
  • What Is The Urgency?

15
Work Zone Fatalities (NHTSAs FARS data)
16
WZ Crashes
  • Majority occur
  • Beginning of the queue
  • In the transition zone
  • Caused by
  • Excessive speed
  • Driver inattention

17
Why We Must Change!
  • TEA-21 gt 40 increase in funding
  • Volume of traffic increasing
  • Highway system aging
  • Public demanding virtually unlimited mobility

18
Alternative is Unacceptable!
  • Significant increases in
  • WZ crashes, disabling injuries and fatalities
  • Highway worker injuries and fatalities
  • Motorists delay in WZs
  • Cost of goods

19
Straight Line Projection
  • 33 increase in number of WZs, resulting in
  • 240 more people killed
  • 12,333 more disabling injuries
  • 44 more highway workers killed

20
Q. Whats the publics biggest complaint?
  • A. The lane is closed and theres no work going
    on!

21
The Public Wants Us To
  • Get In!
  • Do It Right!
  • Get Out!
  • Stay Out!

22
Ways to Reduce Exposure
  • Reduce
  • Volume of traffic in WZ
  • Time WZ is in place
  • Number of WZs

23
Reduce Volume of Traffic in the WZ
  • Closing the facility
  • Diverting to other routes
  • Diverting to other modes
  • Spreading out peak hour volume

24
Reduce the Volume of Traffic in the WZ
  • Bostons Central Artery Tunnel
  • Utahs I-15 Reconstruction
  • Washington/Oregon I-5 Bridge Repair
  • Advance information (SmartWorkZone, Adaptir,
    and Travel Time Prediction System

25
Maybe were doing the public a disservice by not
closing down the road to do the work. ...State
DOT Executive
26
Reduce the Time the WZ is in Place
  • Time-based bidding (AB, I/D, Lane Rental, etc.)
  • Variable start dates
  • Window specs
  • CPM to establish, manage, and monitor contract
    time

27
Reduce the Time the WZ is in Place
  • Washingtons I-405 Resurfacing
  • Floridas Innovative Contracting
  • Utahs Use of Contractor TCPs
  • Marylands Constructibility Review
  • Pennsylvania Turnpike Authoritys two shift
    requirement

28
Reduce the Number of WZs
  • Improved designs
  • Longer-lasting products materials
  • Performance-based specs
  • Warranty specs
  • Preventive maintenance program
  • Corridor traffic management

29
Reduce the Number of WZs
  • Colorados I-25 Reconstruction
  • Californias I-5 Corridor Reconstruction
  • IDOTs Combining of Projects

30
11 Major Areas
  • Traffic Management vs. Traffic Control
  • Prediction Modeling Impact Analysis
  • Commitment of Top Management
  • Traveler Traffic Information Programs

31
To the public the worst thing is being delayed.
The second worst thing is not knowing why theyre
being delayed. State DOT Executive
32
11 Major Areas
  • Traffic Management vs. Traffic Control
  • Prediction Modeling Impact Analysis
  • Commitment of Top Management
  • Traveler Traffic Information Programs
  • Development of TMPs TCPs

33
Degree of Influence on Reducing WZ Delay and
Enhancing Safety
High
Low
Policy Planning Design Construction
34
Philosophy
  • A typical Toll Authority figures out the best way
    to handle the traffic, then designs the project
    around the traffic.
  • A typical DOT designs the project, then figures
    out the best way to handle the traffic.

35
11 Major Areas
  • Traffic Management vs. Traffic Control
  • Prediction Modeling Impact Analysis
  • Commitment of Top Management
  • Traveler Traffic Information Programs
  • Development of TMPs TCPs
  • Contracting Bidding Procedures

36
Contractors are in business to make money!
State Highway Agencies are in business to serve
the public by getting projects built!
37
Goal
  • Quality, high-performing project, that minimizes
    delay and disruption to the traveling public, and
    which ensures a reasonable profit to the
    contractor.

38
We would much rather chase a carrot than run
from a stick. ...Contractor
39
11 Major Areas (contd)
  • Specifications and Construction Materials,
    Methods, Practices
  • ITS Innovative Technologies
  • Enforcement
  • Public Relations, Education, and Outreach
  • Evaluation Feedback

40
Other Observations
  • Info to public
  • Constructibility
  • Contractor TCPs
  • Night work
  • State Police

41
Other Initiatives
  • NJs Dedicated Trooper Unit
  • NY States WZ Crash Analysis
  • NCs WZ Info Unit
  • NAPAs, Caltrans, IDOTs, WashDOTs Workshops
  • ARTBA/FHWA sponsored National WZ Safety
    Information Clearinghouse (NWSIC)

42
What the public experiences in the WZ is how they
judge the highway community!
43
Partnership
  • Industry
  • State DOTs
  • FHWA
  • Others

44
What Can You Do?
  • Some suggestions
  • Dont accept what weve always done
  • Customer perspective
  • Work to reduce exposure
  • Only take lane when needed
  • Commit to Truth in signing

45
Where Do We Go From Here?
  • Some suggestions
  • Joint benchmarking
  • Identify joint WZ initiatives
  • Set WZ performance goals
  • Set up team to look at WZ policies and/or specs
