Th Hi h P f M it i S t (HPMS) idThe Highway Performance Monitoring System (HPMS) providesessential data on highway conditions, performance and usage aswell as analytical products to the entire transportation community.

The HPMS was developed in 1978 to serve highway transportationdata and analytical needs at the national level. It replaced numerousuncoordinated annual State data reports as well as biennial specialstudies conducted by each State, resulting in a reduction in annualState data reporting.

Vehicle Miles Traveled (VMT) EstimatesVehicle Miles Traveled (VMT) EstimatesAs with all states, New Jersey’s official estimate of vehicle miles traveled(VMT) is a product of the HPMS Program. VMT is simply a measurementof the amount of traffic on a given mile of roadway. Deriving NewJersey’s VMT estimate involves multiplying the traffic volume in eachHPMS section, the section length and expansion factor, then summing theproduct to yield the VMT for any desired aggregation level.

VMT estimates are a key component of the Federal-Aid Highway fundapportionment formulae. They are central to estimating several of theDepartment’s performance indicators such as vehicle crash and fatalityp p yrates. VMT are also used in tracking Clean Air Act requirements and arecritical in the analysis that support the Condition and PerformanceReports to Congress.

Public Roadway Mileage and CertificationPublic Roadway Mileage and CertificationPublic roadway mileage figures are maintained by the BTDD throughPublic roadway mileage figures are maintained by the BTDD throughroad inventory efforts. A public road is any road or street owned andmaintained by a public authority and open to public travel. Each year inresponse to the Federal Aid Policy Guide Transmittal 1, dated December9, 1991, the BTDD acts as the designee of the Governor and provides theFHWA with New Jersey’s Certification of Public Road Mileage. Thisfigure represents mileage as of the end of a calendar year.

New Jersey has approximately 3838,,000000 milesmiles of public roadways. Certifiedpublic mileage figures, both current and historical, are available on theDepartment’s web site and can be dis-aggregated by either functionalp gg g yclassification or jurisdiction.

Functional Classification SystemFunctional Classification SystemDevelopment / maintenance of New Jersey’s Functional ClassificationSystem is performed in accordance with procedures set forth in the ISTEAof 1991 Section 1006 (c). Functional Classification is the process by whichall public roadways are grouped into categories based on the service theyare intended to provide. Smaller, less traveled roadways (local roads)are intended to provide. Smaller, less traveled roadways (local roads)provide motorists with a high degree of access. On the other hand, largerroadway (Interstates and freeways) provide motorists with a high degree ofmobility.

Another factor in the development of the Functional Classification Systemis Census data. This data determines the development of the UrbanBoundary which delineates the Rural and Urban classificationsBoundary which delineates the Rural and Urban classifications.Development of the Functional Classification System is performed incooperation with County and Metropolitan Planning Organization (MPO)officials. Functional Classification System statistics are available on theDepartment’s web site.

As withthe Functional Classification System, the NHS is developed in cooperationwith County and MPO officials.

Route MilepostingRoute MilepostingMileposting of State Highways is performed to establish beginning, endand intermediate points along each route. These measured distances andpoints result in the installation of the small green placards along theshoulder of State Highways The location of these placards are based onshoulder of State Highways. The location of these placards are based onroad inventory data and measurements obtained from Distance MeasuringInstruments (DMIs) installed in field vehicles.

Federal guidelines require BTDD to establish the location of 11//1010 milepostplacards on all Interstate Highways and 11//22 milepost placards on all otherState Highways.

We also milepost new routes, emergency evacuation routes andemergency service patrol (ESP) routes.
