  2. Agenda • Safety Planning (Goals and Objectives) • Safety Planning Process • Data Overview • State & ATP Level • County level • Safety Emphasis Areas • Safety Strategies • Safety Strategies Workshop • Breakout Groups • Voting Exercise

  3. Goals and Objectives • Data driven • The new National Safety Performance measure = SEVERE crashes • 4 E’s • Foster safety culture among county stakeholders • Development of County Safety Plans • Unique safety plan • Establish safety emphasis areas • High priority safety strategies • Safety investment options • Identify high priority safety projects, both proactive and reactive. • Position counties to Compete for Safety Funds • Highway Safety Improvement Program • High Risk Rural Roads Program • Minnesota Central Safety Funds

  4.

  5. ATP 7 County Severe Crash Numbers • No county in ATP 7 has a high number of severe crashes on their highway system. • No county has enough severe crashes to support the development of a safety plan through a data driven process. • ATP7 does have enough severe crashes – the ATP totals will be used to identify safety emphasis areas for all of the counties. Note: Steele county does not have a large enough crash dataset to be analyzed separately. Steele crashes are 62% rural, while other ATP 7 counties are on average 77% rural. Therefore Steele will be included in ATP 7 analysis. Legend 10/yr (50 total) - Severe crashes on any jurisdiction 4/yr (20 total) - Severe crashes on CSAH/CR MnCMAT Crash Data, 2006-2010 Severe = K (fatal) + A (life-changing injury) 7/yr (34) 3/yr (15) 12/yr (60) 7/yr (35) 10/yr (49) 3/yr (17) 7/yr (37) 3/yr (14) 4/yr (22) 3/yr (15) 5/yr (23) 1/yr (4) 22/yr (122) 10/yr (48) 9/yr (47) 5/yr (25) 16/yr (79) 5/yr (23) 5/yr (23) 1/yr (7) 11/yr (55) 3/yr (14) 9/yr (47) 3/yr (16) 10/yr (49) 4/yr (20) 7/yr (34) 2/yr (12)

  7. Workshop Group 7C Crash Data Overview Source: MnCMAT Crash Data, 2006-2010 Severe is fatal and serious injury crashes (K+A). 5 Year Crashes Group 7C 4,072 148 Cottonwood, Jackson, Nobles & Rock Example All – % Severe – % • In Cottonwood, Jackson, Nobles & Rock Counties: • 52% of severe crashes are on the state systems • 28% of severe crashes are on the county roadways • 54% of the severe crashes on the county roadways are RURAL • 27% of rural severe crashes are at intersections road and 68% are non-intersection related • 80% of severe non-intersection related crashes are run off the road. • 50% of severe intersection related crashes are at Thru/STOP (2-way STOP) locations and 33% of those are Right Angle Crashes State System 2,076 – 51% 77 – 52% CSAH/CR 931 – 23% 41 – 28% City, Twnshp, Other 1,053 – 26% 30 – 20% Rural 153 – 16% 22 – 54% Not Animal 130 – 85% 22 – 100% Inters-Related 33 – 25% 6 – 27% Not Inters-Related 93 – 72% 15 – 68% Thru-Stop 9 – 27% 3 – 50% Run off Road 62 – 67% 12 – 80% On Curve 4 – 6% 0 – 0% Right Angle – 2 (22%), 1 (33%)

  8. Workshop Group 7C Emphasis Areas • The idea behind Safety Emphasis Areas is to assist the safety planning process by providing a uniform set of crash types and characteristics that encourages establishing safety priorities – identifying the types of crashes that result in the greatest number of fatalities and severe injuries. • County roadways in ATP 7, the Top 5 Safety Emphasis Areas include: • Young Drivers, Impaired Drivers, Unbelted Occupants, Road Departure and Intersections • In individual counties, the actual number of crashes in each Emphasis Area and the rank order varies slightly, however, because of the low number of severe crashes in each county the differences are not statistically significant.

  9. Screening - Initial Strategies AASHTO’s SHSP, NCHRP Report 500 Implementation Guidelines, and input from Safety Partners. The strategies will be screened using: - Crash data, - Effectiveness, - Cost, and - Input from Safety Workshop. The Critical Strategies should have the greatest potential to significantly reduce the number of traffic fatalities. Speeding 2 Strategies Head On 7Strategies Road Departure 13 Strategies Intersections 77 Strategies Young Drivers 2 Strategies Seat Belts 4 Strategies Alcohol/Drug 15 Strategies Critical Strategies Education Strategies Enforcement Strategies Engineering Strategies Emergency Services Strategies

  10. Safety Strategies Overview NCHRP Report 500 • A series of guides to assist state and local agencies in reducing injuries and fatalities in targeted emphasis areas • The guides correspond to the emphasis areas outlined in the AASHTO Strategic Highway Safety Plan. • Each guide includes a brief introduction, a general description of the problem, the strategies/ countermeasures to address the problem, and a model implementation process.

  11. Example: Intersection Strategy Prioritization 70+ Initial Strategies • Reduce the Frequency through Geometric Design • Optimize signal operation • Indirect Left Turn intersection • Right & Left Turn Lanes • Improve Driver Awareness of Intersections • Enhanced signing and delineation • Supplementary stop signs • Choose appropriate intersection traffic control • Roundabouts • Improve access management near intersections • Restrict access to properties using driveway closures 15+ High Priority • Reduce the Frequency through Geometric Design • Optimize signal operation • Use indirect left-turn treatments • Improve Driver Awareness of Intersections • Enhanced signing and delineation • Choose appropriate intersection traffic control • Roundabouts 5+ Top Voted • Reduce the Frequency through Geometric Design • Use indirect left-turn treatments • Improve Driver Awareness of Intersections • Enhanced signing and delineation • Choose appropriate intersection traffic control • Roundabouts 2+ Critical Strategies • Reduce the Frequency through Geometric Design • Use indirect left-turn treatments • Improve Driver Awareness of Intersections • Enhanced signing and delineation … … Small group discussion and prioritization. Large group discussion and voting. Selection by County Staff. …
