LowCost Safety Improvements Pooled Fund Study

1
Low-Cost Safety Improvements Pooled Fund Study

• FUTURE DIRECTION
• Annual TAC Meeting,2007
• Roya Amjadi
• FHWA, Turner-Fairbank Research Center

2
Objective One

• First Phase III of the Low-Cost Pooled Fund
  Study (PFS) need to be discussed for two
  categories of strategies
• Leading strategies that were selected from Phases
  I and II and have potential to be evaluated in
  this phase
• Strategies listed from the next selected series
  of NCHRP 500 volumes

3
Objective Two

• Second Select strategies that meet following
  criteria
• Hold most interest for the State DOTs, AND
• Strategies may have been built in several
  locations with available Before/After data
  (retrospective), OR
• Strategies may be studied in simulation Labs, OR
• Strategies will be built by the State DOTs for
  evaluation (prospective).

4
What Tool Do We Need ?

• Recalling what was discussed Yesterday and
  Today
• Phase I II, strategies 1-8, and types of the
  evaluations (Before/After, retrospective),
• Phase IV, strategies 9-17, and types of the
  evaluations (simulations), and
• Information gained through the yesterdays tour
  and discussion on Phase IV.

5
Warming UP for Phase IIIIn Two Steps

• Due to limited time, please have in mind that we
  DO NOT have to decide all the strategies today.
• Only strategies with high ranks and feasibility
  will be considered.
• The longer list will be e-mailed to you, we will
  communicate, and refine our selections later.

6
1- Strategies selected in Phases I and II
Discussion and Balloting

• Technical Advisory Committee (TAC) members may
• Provide technical information/updates, and
  exchange ideas on various listed strategies for
  (15 minutes)
• Select and rank listed strategies on their
  appropriate balloting forms (5 minutes)

7
2- Strategies in NCHRP 500 Series Discussion
and Balloting

• Technical Advisory Committee TAC members may
• Provide technical information/updates, and
  exchange ideas on various listed strategies for
  (15 min.)
• Select and rank listed strategies on their
  appropriate balloting forms (5 min.)
• Ballots will be collected at end of the hour.

8
Strategies selected in Phases I and II

• Alternating passing lanes or four-lane sections
  at key locations to prevent Head On crashes
  (I-R5)
• Median barriers for narrow-width medians on
  multilane roads to prevent Head On crashes (I-R7)
• Install profiled thermoplastic strips for
  centerlines (I-R11)
• Narrow buffer median on two lane roadways
  (I-R12)
• Increase size and letter height of roadway signs
  (II-R7)
• Provide adequate sight distance (II-R10)

Strategies in NCHRP 500 Series

• A Guide for Reducing Collisions Involving Heavy
  Trucks (V13)
• A Guide for Reducing Alcohol-Related Collisions
  (V16)
• A Guide for Reducing Crashes Involving Drowsy and
  Distracted Drivers (V14)
• A Guide for Enhancing Rural Emergency Medical
  Services (V15)

10
A Guide for Reducing Collisions Involving Heavy
Trucks, V13

• Identify and treat truck crash roadway segments
  signing
• Install interactive truck rollover signing
• Promulgate Share the Road information through
  print and electronic media
• Increase and strengthen truck maintenance
  programs and inspection performance

11
A Guide for Reducing Collisions Involving Heavy
Trucks, V13 Continued

• Perform safety consultations with carrier safety
  management
• Promote development and deployment of truck
  safety technologies
• Increase efficiency of use of existing parking
  spaces
• Create additional parking spaces
• Modify speed limits and increase enforcement to
  reduce truck and other vehicle speeds

12
A Guide for Reducing Alcohol-Related Collisions
(V16)

• Conduct Regular Well-Publicized DWI Checkpoints
• Enhance DWI Detection Through Special DWI Patrols
  and Related Traffic Enforcement

13
A Guide for Reducing Crashes Involving Drowsy
and Distracted Drivers (V14)

• Implement other roadway improvements to reduce
  the likelihood and severity of run-off-road
  and/or head-on collisions
• Implement roadway improvements to reduce the
  likelihood and severity of other types of
  distracted and drowsy driving crashes

14
A Guide for Enhancing Rural Emergency Medical
Services (V15)

• Integrate information systems and highway safety
  activities
• Integrate EMS systems into the Safe Communities
  effort
• Identify and evaluate model rural EMS operations

15
Items forFuture Communications

• We need to exchange information for
• Review and discussion of various NCHRP-500 (V13,
  14, 15, and16) strategies in detail for
  feasibility,
• Providing data as objective measures of
  importance for strategies when possible,
• Refining the list for specific strategies that
  hold most interests to DOTs,

16
Items forFuture Communications

• Existing sites with implemented strategies,
• Available Before/After data,
• States interests in building and studying
  strategies,
• New feasible ideas, and
• Related issues.
