Infrastructure & Mobility Planning

December 9, 2020

MPO• Pavement performance measures

• Historically, windshield survey and inconsistent with MDT pavement assessment

• Better alignment with assessed pavement when coordinating with other projects; water, sidewalk and utility improvements

City and County• Budget assessments

• What are current (October 2019) conditions

• Reports to assess future budgetary needs

• Work plan inputs

Overall reporting• MPO – Urbanized Area (UZA) summary report

• City – City Limits detailed report

• County – County (Outside City Limits) detailed report

Purpose & Outcome

Data collection

• Lidar

• Lasers!

• Imagery

LIDAR• Inventories

• Traffic Signs, Street Paint condition, Storm drains, Manholes, Curb/Gutter/Sidewalk, ADA facilities

• Problem Identification• Sight Obstruction, Pavement Condition (Identified)

Inventory Potential

Pavement Asset Management

Use PCI and modeling to develop data-driven approaches to

pavement maintenance

Asset Management Tools

MicroPAVER

• Models and projects pavement condition under different

maintenance schedules & budgets

• Inputs:

• Road classification

• Deterioration model

• Current PCI

• Maintenance costs (chip seal, mill/overlay, reconstruction)

• Budgets

Pavement deterioration

Estimated cost to “fix all”

Key takeaways

o Our current budgets are not keeping up with need

o However, we need more data to determine accuracy of projections

o This report is just the first baseline

o Can help evaluate work plans, but MicroPAVER won’t tell us exactly what to do

o Part of an overall asset management strategy – Streets, utilities, public infrastructure
