Overview

• These procedures are intended to instruct
  personnel in the general duties and field methods
  used in performing Roadway Inventory. It cannot
  supply answers to all questions that may arise
  nor does it address every situation that exists
  in the field, but it will give personnel an
  understanding of their principal duties.
• Some ingenuity may be required of the field and
  office personnel in dealing with unique
  situations which cannot receive specific
  attention in these guidelines. Supervision
  should be consulted as soon as practicable on
  doubtful issues.

4
Purpose of Roadway Inventory

• Roadway Inventory is conducted to collect
  descriptive and statistical data on all roadway
  systems.
• The collected data is used for various reporting
  within the Department and in all certification of
  Public roadway mileage.

5
Extent of Inventory

• The inventory will cover every road, street and
  alley throughout the State which is open to the
  public and regularly used by motor vehicles.
• Exceptions will be primitive or overgrown roads
  or trails, which do not connect places or
  residence, business, industry or recreation.
• The purpose of the exceptions is to exclude the
  numerous inconsequential roads and trails which
  exist in some municipalities.

6
Method of Inventory

• The inventory will be taken by driving a motor
  vehicle over the road to be inventoried and
  recording the location of items to be inventoried
  in relation to the beginning point of the road.
• The recorded locations will be supplemented by
  descriptive data as necessary.
• Recording will be conducted using automated
  roadway inventory / data collection software and
  devices that have been approved or prepared
  forms.
• Details are described in these procedures.

7
Order of Inventory

• The Supervisor of the inventory project will
  determine in advance which roads receive priority
  for the inventory process.
• Typically, road inventory is performed by the
  route hierarchy system
• Interstate
• US
• NJ
• 500 System
• 600 System
• and then at the municipal road level.

8
Direction of Survey

• All route systems will be inventoried in the
  roadways primary direction starting at the
  southerly or westerly most point and continue in
  the northerly or easterly direction.
• A comparison of the existing roadway inventory
  notes, if available, will be consulted to
  determine if the roadways primary direction is
  currently established.

9
Numbering of Roadway Systems

• All roadways inventoried will be assigned a
  unique Standard Route Identification number
  (SRI).
• Currently, local roadways in each municipality
  are assigned a four (4) digit number. This number
  will be incorporated into the new SRI in order to
  avoid renumbering the existing inventory sheets.
• The method of assigning and deriving SRI numbers
  is detailed in the information package.

10
Numbering of Roadway Systems

• All roads and streets will be classified into one
  or more of the following route systems
• 1. Interstate Routes
• 2 . U. S. numbered Routes
• 3 . New Jersey State Highways
• 4 . 500 Routes
• 5 . County Roads
• 6 . Municipal streets and selected private
  roads
• and .

11
Numbering of Roadway Systems

• 7. Authority roads - this includes
• New Jersey Turnpike
• Garden State Parkway
• Atlantic City Expressway
• Palisades Interstate Parkway
• which may be inventoried when directed.

12
Roadway Inventory

• Prior to inventory, data will be supplied that
  has been recorded on Roadway Inventory Sheet
  (PT-B-21) revised or contained in electronic
  database format.
• This data will include, but is not limited to
• Mileage with respect to the beginning of the
  route
• Length of section
• Cross section
• Pavement surface type
• Number of lanes
• Location of structures, etc.

13
Roadway Inventory

• During normal inventory, the accuracy of the
  data will be verified. All new roadways not
  previously inventoried will have the above
  features recorded electronically and new
  inventory sheets will be prepared if required.
  In cases of disagreement the new data will be
  recorded and the previous data will be struck out
  but NOT obliterated.
• In addition, data not previously recorded on
  existing data sheets will be collected. Data may
  include
• Width and type of shoulders
• Presence of curbing
• Parking regulations as noted by signing
• Location of signalized intersections

14
Roadway Inventory

• Following the completing of Roadway Inventory in
  each municipality, a database containing raw data
  in an approved electronic format and the field
  notes will be made available.

15
Roadway Inventory

• Roads that have an official route number (i.e.
  505, 605, 705, etc.) will be identified by that
  number in the SRI when being inventoried.
• Municipal roads should be numbered
  consecutively, beginning with number 1001 as the
  last four numbers of the assigned SRI number in
  each municipality.

16
Roadway Inventory

• Local roads which cross municipal boundaries
  will be inventoried starting in the municipality
  in which the roadway originates and is to
  continue in the primary direction until the point
  of the roadways termination.
• The portion of the roadway that deviate outside
  of the starting municipality will be
  cross-referenced in the adjacent municipalitys
  notes.
• There is to be no overlapping of inventoried
  roads.

17
Roadway Inventory

• County and Corporate Line roads will be logged
  at the time the County in which they appear is
  being inventoried. The jurisdiction of these
  roads will be determined by the office personnel.
• Except when otherwise directed, all roads
  usually open for the use of the public in State
  and Federal reservations will be inventoried.
• When maps for there areas are available, they
  will be supplied to the field personnel.

18
Classification of Surface Types

• Each section of road will be classified by
  inspection and recorded in the appropriate data
  field under one of the following types
• Type G Low Type Bituminous Road
• A mixed bituminous or bituminous penetration
  road, with a surface course of one inch or more
  of compacted thickness, consisting of
• Gravel
• Stone
• Sand or similar material
• mixed with bituminous material under partial
  control as to grading and proportions.

19
Classification of Surface Types

• Type I High Type Bituminous Road
• A road which has been constructed of a surface of
  one inch or more in compacted thickness
  consisting of
• Bituminous concrete or sheet asphalt, prepared in
  accordance with precise specifications
  controlling graduation, proportions and
  consistency of composition
• or of
• Rock asphalt
• The surface course may consist of combinations
  of two or more layers such as a bottom and top
  course, or a binder and a wearing surface.

20
Classification of Surface Types

• Type J Portland Cement Concrete Road
• A road consisting of
• Portland Cement concrete surfaces
• Type K Brick Road

  when present on BRIDGES of lengths of 500 feet or
  more.

22
Roadway Inventory Data Collection

• The following is a summary of the data needed to
  be collected for each section of roadway
  inventoried. Data will be collected in an
  electronic format using approved roadway
  inventory/data collection software and devices.

23
Roadway Inventory Data Collection

• A Roadway Inventory Sheet shall be generated for
  each roadway if required
• 1. Record the County and Municipality in which
  the portion of inventoried road is located. If a
  corporate line is crossed or is along the center
  of the road, identify both municipalities in the
  heading.
• 2. All inventoried roads will be identified by
  their official route numbers and by SRI numbers.
  Roads or sections of roads which are on two or
  more route systems, will be identified by all the
  route numbers applicable.

  be along the center line of the inventoried road
  on contiguous or uniformly divided highways. At
  times it will be necessary to conduct inventory
  in both directions.
• Examples of this are widely separated roadways
  on different alignments or on different levels,
  complex interchanges and road where visibility is
  restricted because of road geometrics.
• Items are to be recorded in the appropriate data
  field on the right and/or left of the center line
  at the mile post in the direction of the survey.

27
Roadway Inventory Data Collection

• 10. Intersecting streets and ramps will be shown
  by single straight lines approximating the actual
  angles of intersection with the road being
  inventoried.
• Streets will be identified by their name and
  number.
• The direction of traffic will be shown for all
  ramps and one way streets that intersect the road
  being inventoried.
• 11. Railroad grade crossings will be shown the
  same as streets, but the railroad symbol will be
  used instead of lines. A single symbol will be
  used regardless of the number of tracks and the
  mile point location of the center of the track
  shall be recorded.

28
Roadway Inventory Data Collection

• 12. All bridges and other structures carrying the
  road and having a total opening of over 20 feet
  as measured in the direction of inventory will be
  recorded in the appropriate data field.

  which the aggregate length of spans or diameters
  plus the intervening separations, piers or fill
  material is more than 20 feet as measured along
  the center line of the road shall also be shown
  as a bridge structure.
• EXCEPTION Such multiple culverts or pipes shall
  be considered separate structures if the fill
  between adjacent openings is greater than one
  half the smaller opening, then each structure
  must meet the 20 foot requirement to qualify as a
  bridge. Visible stream crossings of the
  inventoried road will be recorded in the
  appropriate data field.

29
Roadway Inventory Data Collection

• 13. All structures passing over the road will be

  boundaries will be recorded in the appropriate
  data field and shown by a dot-dash line on the
  inventory sheets.
• The names of the municipalities should also be
  shown in their proper positions. When these
  boundaries cannot be determined physically, they
  should be scaled from available maps, and marked
  scaled from map.

  of traffic shall not be recorded.

32
Roadway Inventory Data Collection

• 18. The descriptive items that relate to the
  roadway between the outer edges of shoulder or
  pavement will be recorded in the appropriate data
  field or on the inventory sheet in the columns
  provided as they appear in the field.
• Whenever a change occurs in one or more of the
  items and continues for a significant distance,
  500 feet or more, the complete roadway section
  shall be recorded along with the mile point
  reading in the appropriate data field.
• Cross sections of contiguous roads shall be
  recorded in the appropriate data field or
  entirely on the right side of the inventory sheet.

33
Roadway Inventory Data Collection

• The cross sections of reverse runs will be
  recorded in the appropriate data field or on
  their respective sides of the inventory sheet
  since it would appear that way in the field.
• The recording of road data should be kept clear
  of any diagrams and descriptive data fields at
  all times to maintain clarity in the notes.

34
Roadway Inventory Data Collection

• Specific items and the manner of recording are
  as follows
• a. Record the measured width and the alphabetical
  symbol for the surface type in the appropriate
  data field. When recording the width of
  composite roadways show every surface type
  present in the roadway in addition to all
  shoulders if they are present.
• b. Show the minimum number of lanes available to
  traffic during a 24 hour period. The number of
  lanes shall be recorded individually for each
  roadway.
• When lanes are not marked
• 14 feet shall be considered the minimum width
  required for two (2) lanes of traffic
• 3 lanes must be lined

35
Roadway Inventory Data Collection

• 4 lanes must either be lined or at least 40
  feet in width.
• For 5 lanes or more, an allowance of 10 feet in
  width is required for each additional lane.
• While these criteria will serve as a guide,
  actual usage shall be the primary consideration
  in determining the number of lanes.
• c. Shoulder measured width and surface type shall
  be recorded in the same manner as the roadway.
  The width to be considered refers to that portion
  that is usable and within the roadway limits.
• d. Parking shall be recorded as follows
• U - Parking is permitted and obviously
  possible so that the roadway or shoulder is
  subject to parking all or some of the time.
• M - Metered
• P - Parking prohibited at all times

36
Roadway Inventory Data Collection

• e. The presence of curb and gutter shall be
  recorded when such curbs define any side of the
  roadbed, pavement or median and are present for a
  minimal continuous length approximating 500 feet.
• f. The types and measured widths of medians and
  lane separators shall be recorded when present
  for length approximately 500 feet or more.
• Measured widths shall be recorded to the nearest
  lowest foot.
• When widths are not uniform, the points of
  change shall be located and the measured widths
  at these points shall be recorded.
• Average widths shall not be recorded.
• The type of median normally has reference to the
  surface covering and is recorded as one of the
  roadway surface types.

37
Roadway Inventory Data Collection

• Parkland or Business shall be substituted
  for the surface type when the median is used for
  either of these purposes.
• The heights of barrier curbs are measured to the
  nearest inch.
• These measurements are critical, especially
  when recording heights that approach 16, 24 and
  36. Barriers and guide rail in the median shall
  be recorded. The recording of heights of guide
  rail is not required.
• g. All openings in the median, which are used for
  the passage of vehicles shall be recorded in the
  appropriate data field. The recordings shall
  clearly indicate the direction of passage through
  the openings. Openings which are reserved for
  the passage of official vehicles - police, fire,
  rescue, etc. - shall also be recorded but clearly
  distinguished from all others. Openings which
  allow the passage of vehicles at street
  intersections shall be recorded in such a manner
  as to clearly indicate directions and turning
  movements available to vehicles.
