2 The Problem: 1200 Fatalities Fatal Crash Locations are Random

3 The Problem: 1200 Fatalities Fatal Crash Types are Not Random (3-years of data)

4 Solving The Problem 1. Goal 2. Focus 3. System Solutions 4. E s

5 Solving The Problem Regional Coalitions

6 Solving The Problem Identifying the Essential Eight 1. Primary Seat Belt Law 2. Public Education 3. Targeted Enforcement 4. Punish Drunk Drivers 5. Median Cable Barrier 6. Rumble Strips 7. Signs & Stripes 8. Shoulders System Improvements

7 Acting on the Essential Eight Behavioral Solutions

8 Arrive Alive

9 Living With Seat Belts 77% Observed Usage 23% Not belted Belted Fatalities 68% 32%

10 Use Sporting Events

11 Keeping Our Youth Alive

12 Punish Drunk Drivers

13 Acting on the Essential Eight Engineering Solutions

14 System-wide Safety Solutions Where does Missouri begin to address its 32,000-mile system? Major & Minor Roads Major Minor Roadway Miles 5,500 26,500 Miles Traveled 80% 20% Fatalities 45% 55%

15 Acting on the Essential Eight Smooth Roads Initiative

16 Smooth Roads Initiative OVERVIEW Funding Bond Issue Improve 2,200 miles of most heavily traveled roads 7% of state mileage 60% of annual VMT on these routes Projects Completed

17 Smooth Roads Initiative TREATMENTS New Roadway Surface Asphalt Overlay Concrete Diamond Grind 6 Edgelines: Rumble Stripe (Epoxy) 6 Lane Lines: 3M Waffle Tape Some wet-reflective

18 Smooth Roads Initiative TREATMENTS

19 Smooth Roads Initiative TREATMENTS Delineate Everything Emergency Reference Markers Sign upgrades

20 Smooth Roads Initiative TREATMENTS

21 Acting on the Essential Eight Better Roads, Brighter Future

22 Better Roads, Brighter Future OVERVIEW Existing district funds Next 3,300 miles Mostly Two-lane 85% of major roads will be in good condition by 2011

23 Better Roads, Brighter Future TREATMENTS All major roads (5,500 mi) will have Minimum 4 feet paved shoulder Smooth driving surface Improved signing 1,000+ miles will receive Edgeline and Centerline rumble stripes

24 Acting on the Essential Eight Imbed Safety into MoDOT Policy

25 Imbed Safety into Policy MoDOT s Engineering Policy Guide

26 Imbed Safety into Policy Rumble Stripes (Edgeline & Centerline) All major roads All minor roads with crash history 6-inch Stripes for Major Roads All Edgeline Multi-lane skips Curve Speed Plaques Every Curve/Turn sign

27 Acting on the Essential Eight Median Cable Barrier

28 Median Guard Cable Spot Locations in St. Louis and Kansas City System-wide Installation Criteria Interstates Severe Crash History Current Installations 500 miles installed Low & High Tension

29 Acting on the Essential Eight Evaluation Good Investment?

30 Evaluation Effectiveness Does the treatment perform as intended? Safety Analysis Are we reducing severe crashes? Are we saving lives?

31 Effectiveness: SRI Evaluation In progress Initial results showing statistically significant improvement

32 Effectiveness: SRI Before After

33 Effectiveness: Guard Cable Studied all reported cross-median crashes ,400 crashes 95% Success Rate Vehicles did not enter opposing lanes

34 Cross-Median Fatalities Guard Cable Installation (miles) Safety Analysis: Guard Cable I-70 Cross-Median Fatalities

35 Cross-Median Fatalities Guard Cable Installation (miles) Safety Analysis: Guard Cable I-44 Cross-Median Fatalities

36 Fatalities Safety Analysis: Guard Cable Interstate Cross-Median Fatalities

37 Saving Lives Missouri led the nation in saving lives in 2006 (nearly a 13 percent decrease). Of the 868 fewer traffic deaths nationwide, Missouri accounted for 161 of them.

38 Saving Lives 21 percent decrease in fatalities from 2005 to percent decrease in fatalities from 2006 to ,257 fatalities in ,096 fatalities in fatalities in Haven t had fewer than 1,000 fatalities since years ago.
