1. LAKE COUNTY DIVISION OF TRANSPORTATION PROPOSED 2015-2020 HIGHWAY IMPROVEMENT PROGRAM OVERVIEW AND PROGRAM PRIORITIES Paula J. Trigg, County Engineer Public Works and Transportation Committee April 29, 2015

2. Presentation Schedule 2 PWTC 2015 Meeting DatePresentation Topic April 29 Overview and Program Priorities June 3 Funding and Projects / Draft Program Document

3. Improving transportation a top strategic goal for Lake County and regional partners 3

4. Efficient Transportation Contributes To:  Quality of life  Environmental value  Economic growth

5. 2015 Construction Program  Continued from 2014  Preservation  Modernization  Expansion

6. $60M continued from 2014 River Road and Roberts Road: New Roundabout Peterson Road, US 45 to w of IL 83: Add lanes Rollins Road at IL 83: Grade separation Wadsworth Road at IL 131: Reconstruct and widen

7. $75M in new projects  24 projects, 11 contain non-motorized travel improvements, (bike paths, or adding bike friendly lanes)  Two significant expansion projects:  Peterson Road Corridor  Washington Street Thoroughfare

8. Communicating with the public  PASSAGE  LCDOT/Lake County website  Facebook  Twitter  LCTV  Public Meetings

9. 2015-2020 Five Year Highway Improvement Program 9 LCDOT’s management philosophy sets system priorities: 1. Preservation 2. Modernization 3. Expansion

10. Priority One: Preservation 10  Tools in the Toolbox:  ARGUS  ARGUS Pavement Management Software  Asset Inventories  Unit cost information  Industry standards 22% Preservation projects: approximately of program

11. LCDOT Uses ARGUS Pavement Management System 11 To make cost-effective decisions:  Where repairs are needed  What repair strategies to use  When the repairs should be done Using these program components:  County highway database  Automated pavement testing  Repair strategies with costs  Pavement aging prediction  Optimization program Laser surface testing Dynaflect

12. Pavement Aging Prediction Costs 12 Repairs Made at the Best Time to Maximize Return

13. LCDOT ARGUS results 13  Implemented in 1986  Condition rating has improved from 68 to 81  Backlog/failing pavement area reduced from 55% to 8%

14. Current Pavement Rating is 81(Good) 14 Good (80 – 100) Sections may require crack sealing or a thin overlay. These sections do not require immediate attention. Pavement in this category is generally less than 12 years old. Satisfactory (70-79) Sections may require resurfacing or other rehabilitation in the near future. Pavement is generally 12- 14 years old. Failing (60-69) Will require some type of improvement in the near future to preserve the usability of the surface and avoid the need for reconstruction. This is pavement that is approaching the end of its useable life. Backlog (10-59) May require surface and base course reconstruction to restore roadway serviceability. Some may require total reconstruction, including reconstruction of the subgrade. Pavement in this category is generally more than 15 years old.

15. Traffic Volumes 15

16. ARGUS Summary 16 does… Pavement Management System does…  Assess the present condition of the system  Estimate future road conditions  Identify and rank road projects  Maximize the condition of the system within the given budget does not… Pavement Management System does not…  Replace professional judgment  Provide certain detailed project-specific information  Evaluate storm sewer and other roadway assets

17. ARGUS System Preservation Projects 2016-2020 17

18. Keeping Tabs on the System: Asset Inventories 18  Pavement and bike facilities  Guardrail, bridges, railroad crossings  Signals and signs  Drainage and stormwater facilities  Fencing  More…

19. Pavement: Our most obvious asset lane miles 864 centerline miles 297 miles bike facilities 62 miles paved shoulder 58 average age of roadway 47 average age of surface 12

20. Lake County’s Bridges Highway Bridges: number of bridges 40 average age 26 average deck age 13 Bike and Pedestrian Bridges: number of bridges 21 average age 24

21. Culverts 21 Variety of culvert materials: Concrete Corrugated metal pipe (CMP) Composite PVC Culverts are routinely inspected 9.8 miles in LCDOT inventory

22. By the Numbers Inventory: Non-Pavement Assets 22 16,114 Storm sewer structures 725 Culverts 215 Miles of storm sewer pipe 47 Detention basins 44,642 Feet of fencing 17,785 Feet of retaining wall 22 Miles of guardrail 29 Landscape areas (50 acres) April 2015

23. Inventory: Signs 23

24. Priority Two: Modernization 24  Tools in the Toolbox:  Traffic analysis  Level of Service data  Non-motorized policy/2040 bike and pedestrian priorities  Typically intersection and safety improvements, bike and pedestrian accommodations 24% Modernization projects: approximately of program

25. Bike and Pedestrian Priorities 25 LCDOT existing planned LCFPD existing planned Other jurisdiction existing planned 2040 Non-motorized Plan

26. Level of Service Data 26  Traffic engineers use LOS data to evaluate how a given intersection is functioning.  Better levels of service mean fewer delays at the intersection  C or better meets driver expectations  LCDOT uses Synchro traffic analysis software to evaluate intersection operations and performance Roundabouts (4 total) Level of ServiceAM Peak HourPM Peak Hour (best)A21 B22 C01 D00 E00 (worst)F00 Signalized intersections (268 total) Level of ServiceAM Peak HourPM Peak Hour (best)A6330 B6654 C7269 D3153 E1424 (worst)F2238

27. Average Daily Traffic: Then & Now 27

28. 2015 Crash Summary (2013 TCAS data) 28

35. 2040 Roadway Priorities  Peak period trips estimated to increase by 36% between 2010 and 2040  212 miles of roadway Improvements recommended  7 interchange  9 intersection  65 corridor

36. History: Daily Vehicle Miles 36

37. 2040 Roadway Improvements  Consensus projects  2040 projects  Both LCDOT and IDOT projects  LCDOT has projects right now in planning that can’t even be programmed for construction in this 5- year plan because of available funding.  $1.8 billion still needed to fund remaining projects in the Consensus Plan
