2 LAND AREA: 688 SQ. MI. – 3RD LARGEST IN OHIO 421 C/L MILES 393 BRIDGES (275 NBIS) 1,800 CULVERTS 5,000+ SIGNS 10 RAILROAD CROSSINGS (at grade) CURRENT NUMBER OF EMPLOYEES: 44 HIGHWAY WORKERS: Crash Rates 2009 Ranked 3 rd Statewide in Runoff Road Crash Rates

3 Roadway Feature Inventory Deficiency Inventory Track Deficiency Reduction Trends Create County Work Plan Create Maintenance Budgeting Tool Correlate Deficiencies to Crash Records Correlate Deficiency Reduction to Crash Mitigation Provide Maintenance Record Database

4 Previous CEAO High Crash Location Study performed by HDR will be used to Correlate Deficiency Reduction to Crash Mitigation

5 Locations, Condition and Assessment of the Following: Guardrail Pavement Markings Signs Hazards Ball Bank No Passing Zone Culverts Meaningful Data Naming Convention

6 Collected more than 10,700 features in approximately 6 months (421 centerline miles of county road) 530 Guardrail Segments 421 mi Pavement Markings 8900 Signs 1100 Unprotected Hazards 150 Curves 75 No Passing Zones

7 Guardrail Offset, Condition, Length, Type, Maintenance Signs Location, Code, Condition, Retro, Field Photo, Associated Support Hazards Ditches, Embankments, Culverts, Rocks, Trees, Structures, Pavement Drop-offs, Poles Reasonable assessment of “Hazard” Recommendation

8 Ball Bank Per ODOT Traffic Engineering Manual, Section Curves with Advisory Speeds or Unmarked Curves No Passing Zones Per MUTCD Guidelines Curves, Intersections, Railroad, Bridges, Transitions, etc.

9 Maintenance Zones County Divided into 5 Maintenance Zones Divided by Roadways, not Township Boundaries

13 Standards set for each asset e.g., Pavement Condition Rating Based Loosely on ODOT Rating Criteria Simplified for the County To 1-5 Scale

14 Planning for future needs Track asset costs

15 Tie to hazards Show improvement trends

16 Field Data Entry Associated roadway item information (sign, guardrail) Work required Completion Data Field Photo Google Earth Fly-in Link

17 Follow-up Work Query data to provide decision information Develop initial maintenance plans

18 Most Difficult Part of Database Who will update? Field Techs vs. Office Staff Update Methods Paperwork Field Data Entry – Laptop, Tablet Geo-coded Picture

19 Between Townships/Districts Track work and improvement
