HIGHWAY PERFORMANCEMONITORING SYSTEM

(HPMS)

1

What is HPMS?HPMS is a national highway information system that includes data on the extent, condition, performance, use, and operating characteristics of the Nation's highways.

Details can be found on this website:

https://www.fhwa.dot.gov/policyinformation/hpms.cfm

-------------------------------------------------------------------------------------------------------------------------------------------------------

Caltrans is required to:

1) Submit HPMS required dataset to FHWA by June 15th (April 15th ).2) Submit CA Public Road Mileage Certification by June 1st .

3

HPMS- What to submit?

1) Seventy (70) data items on all “Public Roads”Full Extent, Sample Panels or Summary.(HPMS Field Manual)

2) Linear Reference System (LRS) Network links HPMS sections data by Route ID.

4

Public Road

o A public road is any road or street owned and maintained by a public authority and open to public travel. [23 U.S.C. 101(a)]

o To be open to public travel, a road section must be available, except during scheduled periods, extreme weather, or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs, or regulation other than restrictions based on size, weight, or class of registration. [23 CFR 460.2(c)]

5

Full Extent: Data reported for the full extent of the system (e.g. section level for AADT). (Federal-Aid Eligible: Urban FC1-6; Rural FC1-5)

Sample Panel: Data reported for HPMS sample panel sections (see diagram on next slide).

Summary: Data reported in aggregate form (e.g. Total VMT on Rural FC 6 & 7).

All Road Network of Linear Referenced Data(ARNOLD)

In 2012, FHWA expanded the HPMS reporting requirement for State DOTs to submit all public roads in a Linear Referencing System (LRS).

This requirement is referred to as the “All Road Network of Linear Referenced Data (ARNOLD)”

Challenge: LRS match Certified Mileage

14

Support needed from local jurisdictions: o Provide us your street centerline shapefiles on

public roads with ownership information.

o Review & provide feedback on LRS Route Layer that Caltrans has/will provide for your agency.

All Road Network of Linear Referenced Data(ARNOLD)

Update on LRS “Clean Up” project:

Presentation Notes

HPMS current challenges?Update/maintain local data:To coordinate with 482 cities + 58 counties + 18 MPOs to maintain and update the network data, traffic data, pavement data and shapefiles.

Update/maintain current (Caltrans) All-Roads network:To continue clean up our All Roads LRS network to reflect current ownership, geometry, public roads and mileage.

What is MIRE?MAP-21 and FAST Act required States to have in place a safety data system under the Highway Safety Improvement Program (HSIP). The system must have the capabilities to perform analyses to support the strategic, data-driven, and performance-based goals in the Strategic Highway Safety Plan (SHSP) and the HSIP. These capabilities include: (1) types of roadways covered, (2) types of data included, (3) geolocation of safety data to a common highway basemap, (4) analysis and evaluation capabilities, and (5) the subset of Model Inventory of Roadway Elements (MIRE) to

be collected.

Subset = Fundamental Data Elements (FDE)To be collected within 10 years until 2026

18

The required FDEs are categorized by roadway functional classification and surface type:

TRAFFIC DATA SOUGHT

This form appears as it was since 2012There have been no changes

‘From’ and ‘To’ locations can be either landmark descriptions or lat/long information.

Traffic data is preferable in shapefile format.

Combination-Unit Trucks

These are negligible

AADTAADT is the average daily traffic value that represents all days of the reporting year. AADT reflects application of day of week, seasonal, & axle correction factors. No other adjustment factors are necessary.

48-hour counts are preferred but shorter duration, such as 24-hour counts, are acceptable if these are the latest available. Lacking a traffic count, the AADT may be estimated from a traffic flow diagram, or by other means.

ADT or AADT may be entered. It is not necessary to supply both. 24

Code the K-Factor to nearest whole percent. Don’t use decimals.

TRAFFIC DATA SOUGHT

D-FactorThe percent of the peak hour volume flowing in the peak direction.

This is normally 50-75% (100% for one-way facilities).

It cannot be less than 50% since it is defined by the peak direction.

TRAFFIC DATA SOUGHT

Future ADT (or AADT)This is typically greater than the current traffic volume but not more than 4 times the current traffic volume. Please provide an explanation wherever if it is outside that range.

Year of Future ADT (or AADT)Ideally, this would be 20 years hence. It should not be less than 18 years out but whatever model year is being predicted that is closest to the 20 year target will suffice.

ANY QUESTIONS?

THIS IS WHAT IS NEEDED FOR TRAFFIC DATA

o ADT (or AADT)

o Peak Hour Volume (or K-Factor)

o D-Factor (Directional Split)

o Forecast Traffic

o Truck Percentages (if available)

29

Pavement Data Sought

‘From’ and ‘To’ locations should run from W-E and S-N

30

Pavement Data Sought

IRI & pavement distress data (rutting, faulting, cracking) is often not available from cites & counties

Some locations, primarily principal arterials, have had this information collected under contract

PCI SURFACE TYPE BASE_TYPE

Pavement Condition Index (PCI), a composite index used to assess maintenance & rehabilitation strategies. It should be reported wherever it has been measured according to this spec:ASTM D 6433 (2007): “Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys”

Though the state does not report PCI directly to the FHWA, there is a conversion to Present Serviceability Rating (PSR).
