LAKE COUNTY DIVISION OF TRANSPORTATION PROPOSED HIGHWAY IMPROVEMENT PROGRAM OVERVIEW AND PROGRAM PRIORITIES Paula J. Trigg, County Engineer Public Works and Transportation Committee April 29, 2015
Presentation Schedule 2 PWTC 2015 Meeting DatePresentation Topic April 29 Overview and Program Priorities June 3 Funding and Projects / Draft Program Document
Improving transportation a top strategic goal for Lake County and regional partners 3
Efficient Transportation Contributes To: Quality of life Environmental value Economic growth
2015 Construction Program Continued from 2014 Preservation Modernization Expansion
$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
$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

Five Year Highway Improvement Program 9 LCDOT’s management philosophy sets system priorities: 1. Preservation 2. Modernization 3. Expansion
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
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
Pavement Aging Prediction Costs 12 Repairs Made at the Best Time to Maximize Return
LCDOT ARGUS results 13 Implemented in 1986 Condition rating has improved from 68 to 81 Backlog/failing pavement area reduced from 55% to 8%
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 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.
Traffic Volumes 15
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
ARGUS System Preservation Projects
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…
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
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
Culverts 21 Variety of culvert materials: Concrete Corrugated metal pipe (CMP) Composite PVC Culverts are routinely inspected 9.8 miles in LCDOT inventory
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
Inventory: Signs 23
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
Bike and Pedestrian Priorities 25 LCDOT existing planned LCFPD existing planned Other jurisdiction existing planned 2040 Non-motorized Plan
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

Lake County’s Traffic Signal and Fiber Network miles of fiber optic in place 22 miles under construction 10 miles planned 502 County-involved signals
Expanding Computer Aided Dispatch (CAD) Coverage 31 Connected to 17 dispatch centers Adding 3 dispatch centers 93% of the county is covered 5.52% in progress
32 PASSAGE: Asset Inventories ( ) signals 502 miles of fiber optic 268 hubs and switches 313 PTZ cameras 317 HAR towers 5
Priority Three: Expansion 33 Tools in the Toolbox: 2040 plan State Consensus list Demographic trends Traffic data Typically add lanes or new/extended roads 43% Expansion projects: approximately of program
Keeping up? County-Owned Roads 34 Lane Mile Growth: Growth in Daily Vehicle Miles: ,801, ,691,839
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
History: Daily Vehicle Miles 36
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
