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
Presentation Schedule

PWTC 2015 Meeting Date
Presentation 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

Efficient Transportation Contributes To:
Quality of life Environmental value Economic growth
2015 Construction Program
Continued from 2014
Preservation Modernizatio
n 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

LCDOT’s management philosophy sets system priorities:
1. Preservation2. Modernization3. Expansion
Priority One: Preservation
10
Tools in the Toolbox: 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 areareduced 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 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.

ARGUS Summary
16
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
Pavement Management System does not… Replace professional judgment
Provide certain detailed project-specific information
Evaluate storm sewer and other roadway assets

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

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
