Trends Impacting Roadways in ND

• Oil production

• Changing crop mix

• Highway funding levels and sources

• Population changes

• Construction Inflation and aggregate

resource depletion

• Changing road maintenance practices

State Needs Study 2019-20

• Components of Study

– Updated Traffic Forecasts for State Routes

– FHWA-HERS-ST Needs Analysis for Pavement

and Capacity – Rural and Urban

– Parallel Rural Pavement Analysis with

AASHTO-93 SAS Algorithms

– Bridge Analysis

– Bikeway Ped Analysis as per ND MOVES

– Freight Plan System Bottlenecks

Freight Constraints – State System

Local Roads Needs Study

Operation Prairie Dog

OPD Provision for Local Road Study

HB 1066 section 4:

the state treasurer shall distribute the

remaining money in the fund to non - oil-

producing counties based on the most

recent data compiled by the upper great

plains transportation institute regarding

North Dakota's county, township, and

tribal road and bridge infrastructure

needs.

pg. 15

OPD Provision for Local Road Study

HB 1066 section 4:

The total estimated road and bridge

investment needs for each county is the

twenty-year estimate for unpaved and

paved road and bridge needs as

identified by the upper great plains

transportation institute.

pg. 16

OPD Provision for Local Road Study

HB 1066 section 4:

If the data compiled by the upper great

plains transportation institute includes

more than one twenty-year estimate for

the total needs of each county, the state

treasurer shall use an average of the

twenty-year estimates for each county

pg. 17

Data Collected for 2019-20 Study

• 1,000+ vehicle counts and classifications by

NDDOT & UGPTI (students and consultants)

• 6000 miles of pavement video image and ride

data via 3 smartphone applications

• Gravel costing surveys for 53 counties

• NBIS data on about 2,300 local bridges

pg. 18

Created for the 2019-20 Study

• A statewide TransCAD truck flow model

– Updated Oil & Gas Data from ND Mineral Resources• Inbound fresh water

• Outbound crude oil

• Outbound produced water

– Updated Agricultural Forecasts• Yield and crop mix

• An AASHTO-93 Pavement Deterioration Model

to predict pavement needs and remaining life

pg. 19

2019-20: Gravel Cost and Practices Surveys

• Survey of both counties and townships

• 2019-20 study

– County survey advisory group

– Surveys went out mid-October

– Webinar held to provide instructions and field

questions

– 53 Counties and about 1600 organized TWPs

• Responses reflective of actual improvement and

maintenance activities is critical

• Cost vary by county

– Cost of materials and haul

– Overlay frequencies

– Dust and stabilization practices

pg. 20

Gravel Cost and Practices Surveys• Aggregate (gravel) cost at pit

• Placement cost

• Transportation cost from pit to roads

• Dust suppressant usage/cost

• Stabilization usage/cost

• Intermediate practices

– Double chip seal/armor coat

– Note: Gravel Mtce. Costs

– Vary a great deal

pg. 21

2019-20 Pavement Data Collection

• Condition data collection– Collected data with NDSU Students using smartphones

– Approx. 6,000 miles of paved county roads

– Ride data collected with Pavvet, RoadBump, and

Roadroid

– Video images collected with RIC

• Scoring and reporting of data– NDSU students will do some manual scoring for validation

– NDDOT and MnRoad Sections will be used for calibration

– Data will be referenced to roadways to provide on-line

mapping

– All data will be integrated into AASHTO 93 model

pg. 22

Pavement Condition Status - 2019

2019 Traffic Data Collection

• Data collection– 1/3 collected by NDSU students and 1/3 by contractor

– NDDOT normal count schedule for remaining 1/3.

– 450 counts added to the NDDOT current and past counts.

– Most counts included truck classification

• Traffic data processing– Use ATR’s from around state to factor the data

– Use classification data to factor the volume counts

– Input all traffic data into travel demand model

• Traffic data reporting– Specific count location data will be made available with an

interactive map on the Web.

pg. 24

2019-20 Other Data• Geographic Roadway Inventory Tool

– Purpose: Provide Counties easy on-line tool to enter data

– Pavement type and pavement age

– Strength data – pavement and base thickness and type

– Collected in 2014– Shoulder width information etc...

– Previous FWD will be used to supplement for sub-grade strength

pg. 25

Created for the 2019-20 Study

• A bridge deterioration and improvement

model.

– A study of bridges located on minimum maintenance

roads – approximately 400 bridges excluded from the analysis – this work was done in 2014
