The Metropolitan Houston Traffic Safety Program

Houston-Galveston Area Council

Houston, TX

slide2
Seriousness of Problem
  • 1998-2000: Houston region - 243,616 serious crashes inc. 1,793 fatalities and 274,926 persons injured
  • The region accounted for:
  • 26% of all statewide crashes
  • 27% of all statewide injury crashes
  • 17% of all statewide fatal crashes
  • The region has 22% of the statewide population
  • and, approximately, 21% of the statewide VMT
  • Likelihood of a fatal or injury crash was:
  • 36% higher than statewide average
  • 145% higher than national average
slide3
Purpose of the Program
  • Build a traffic safety program that can reduce crashes
      • Map the crashes
      • Identify hazardous locations and area
      • Conduct the necessary preliminary engineering

Implement roadway improvements

Identify funding sources

Leverage local investment with State and Federal funds

Support other safety efforts

Enforcement

Education

Safety partnerships

slide5
Task: Build a GIS-based

Crash Information System

  • Obtained crash data for entire system
      • State roads
      • Local roads
  • Obtain data on an annual basis
  • Developed geo-referencing methodology
  • Added supplementary data sets (VMT)
  • Developed crash analysis tools
slide8
Task: Identify Conditions Affecting Crashes
  • Improper driving behavior
  • High-risk population
  • High-risk cities & counties
  • High crash roadways and intersections (hot spots)
slide9
High-risk Behaviors: 1998-2000
  • RegionU.S.*
  • Speeding 39%13%
  • Failing to yield 20%19%
  • Failing to stop 11%9%
  • Running a red light 8%5%
  • DUI 7%7%
  • (However, involved in 37% of fatal crashes/39% nationally)
  • Following too close 3%3%
  • Improper turn 2%2%
  • * National Safety Council. U.S. average for 1999. Fatal and injury crashes only
slide12
High-risk Populations
  • RegionU.S.*
  • Teenagers 21%16%
  • (9% of driving age population/5% nationally
  • 17% in fatal crashes /14% nationally
  • 19% in incapacitating injury crashes)
  • Elderly (65+) 8% 8%
  • (9% of driving age population/13% nationally
  • 11% in fatal crashes/13% nationally
  • 9% in incapacitating injury crashes)
  • Male drivers 79% - (Compared to 58% for females
  • 1.7 times more likely to be in fatal crash/1.4 nationally)
  • Pickup truck drivers 31% 31%
  • (More likely to be involved in DUI crash)
  • * National Safety Council. U.S. average for 1999. All crashes.

slide14
Task: Conduct Safety Studies
  • Identify hazardous locations
  • Partner with local government, TxDOT
  • Conduct engineering study
  • Make mitigation recommendations
  • Mitigate hot spot
slide20
Task: Improve Pedestrian and Bicycle Safety
  • Have identified areas that are hazardous
  • for pedestrians and bicyclists (‘hot spots’)
  • Information is used for bike/ped planning
  • Examine sidewalk, traffic control and pedestrian
  • flow dynamics to identify mitigation measures
slide23
Task: Improve Truck Safety
  • Truck crashes a major problem
  • 27% of the State’s truck crashes
  • Information provided on location of crashes
  • Support Houston Police Department’s
  • truck weighing efforts
  • TxDOT has implemented “no truck in
  • left lane” policies on several freeways
slide25
Task: Develop Strategic Safety Plan
  • Have identified 344 major crash hot spots
  • (78+ crashes between 1998-2000)
  • Estimating benefits and costs of mitigating
  • Programming into RTP
slide27
Costs and Benefits of Hot Spot Mitigation (Preliminary)

Annual Number Estimated Estimated

Type of Facility Number of Crashes Cost to Mitigate Annual Benefit

Freeway 150 7,766 $75 million $58 million

Intersection

between

freeway &

arterial road 70 3,756 $35 million $28 million

Arterial road 124 4,930 $62 million $37 million

Other Safety Activities
  • Safety services
        • Train local planners in safety planning
        • Safety courses for judges, Mayors, etc.
        • Provide safety materials for schools
  • Safety partnerships
        • Governmental(TxDOT, DPS, local jurisdictions)
        • Private, non-profit (AAA, insurance, associations)
        • Community groups
  • Promoting good design principles
        • Review project designs for safety
        • Encourage constituents to include safety in design
