1 ARIZONA DEPARTMENT OF TRANSPORTATION HIGHWAY FEATURE INVENTORY SYSTEM (FIS)

2 INTRODUCTION The Feature Inventory System (FIS) replaces an earlier inventory system. Development of the new system began in It began as a research project to create a program to capture not only Roadway inventory items, but also tying those objects to GPS (Global Positioning System) coordinates. This approach not only ensures the ability to locate features, but is also the basis for measurement of linear features such as fence, guardrail, unpaved shoulders, etc. The design of the program is based on requirements provided by members of the Maintenance Servant Leadership Team (MSLT), which includes Maintenance Engineers, Superintendents, Supervisors and Analysts Some of the values of this program include the ability to quantify and locate features for which ADOT is responsible. Having this information will assist the Department in planning maintenance and replacement of the covered features. This information will also tie to the Level of Service (LOS) program. It will also provide useful information on existing features to highway planners for highway rehabilitation or improvement projects. Last, but not least, this information will allow ADOT to provide detailed quantitative information to the Legislature, increasing our accountability and the credibility of budget requests. FORWARD This handbook was created to provide direction for persons collecting Feature Inventory data as well as assisting data collectors with identification of the various features. While an attempt has been made to anticipate and answer questions concerning the data collection process, it is understood that this is a work in progress. In the early phases of the inventory process it is inevitable that many unanticipated situations will be encountered. Your assistance in identifying these situations, documenting them with photographs and notes and sharing them with me will result in ongoing changes to improve this handbook. Your effort in undertaking the inventory process and your commitment to improving the process and documentation is greatly appreciated. Please contact me with your questions and suggestions, and forward any related documents to me. Bob Harris, FIS Field Operations Manager [email protected] Mail Drop 125F, Room M W. Jackson St. Phoenix, AZ Office

3 SAFETY CONCERNS TRAFFIC SAFETY In most cases, data collection will be conducted on or near roadways where traffic is moving at high speeds. Data Collectors must be aware of their movements as it relates to highway traffic and how motorists will interpret those movements. Don t take chances. Allow plenty of time for driving on or off the roadway, or for your movements as a pedestrian. ITEMS FOUND ALONG ROADWAYS All manner of items may be found along Arizona s highways. Items include such things as money, tires, tools, drugs, drug paraphernalia, weapons, body and medical waste to name just a few. In the case of found items of value (excluding drugs or drug paraphernalia, weapons or other prohibited items), these things are to be handled in accordance with ITD Policies & Procedures PER Drugs, drug paraphernalia, weapons or other prohibited items should not be picked up, and in no case shall they be transported in ADOT vehicles. The location of such items should be noted and reported to law enforcement authorities. Other related ADOT Policies MGT-6.04 Weapons in the workplace; PER Drug and alcohol-free workplace policy; SAF-3.01 Exposure control policy. WATCH YOUR STEP! This safety issue applies equally to ensuring solid footing where you are walking or climbing and watching for venomous snakes and insects. Erosion treatments, such as gabion baskets, rip-rap, rail bank protection, etc. are prime habitat for snakes and scorpions.

4 DEFINITIONS Cardinal Direction Direction in which the mile post numbers increase Generally (there are exceptions) northbound and eastbound. Even numbered routes are considered east-west routes. Odd numbered routes are considered north-south routes. NOTE: It is wise to check the photo log prior to beginning data collection on a new route in order to determine direction, E, W, N or S. Cardinal directions for Frontage Roads will ALWAYS be the direction in which MP numbers are increasing. Frontage Road designations include the Route number and either H or K. The H designation will ALWAYS be the designation for the Frontage Road going in the cardinal direction, i.e. a Frontage Road on the south side of I-40 (EB direction) will ALWAYS be the cardinal direction with the designation I-40 H. FIS FISDC Feature Inventory System. The program and process utilized for recording and retrieving data regarding the highways features (guardrail, fence, pipe, unpaved shoulders, etc.). Feature Inventory System Data Collection. That portion of the FIS program and process utilized to capture the highway feature information. Leading/Trailing End Treatments Leading guardrail end treatments are the end treatments you first approach when traveling in the normal traffic direction in a lane. The trailing end treatment will then be on the far end of the guardrail section. On two-way traffic roads with guardrail on both sides, the leading and trailing end sections will be opposite each other. On one-way roadways where guardrail appears on both sides of the roadway, the leading and trailing end sections will be across from each other Ramp Starting/Ending Point On and off ramps begin/end at the point at which the first physical barrier or change occurs in the gore-point separating the ramp from the mainline roadway. This can be a concrete curb, a barrier or unpaved surface.

19 Roadway Barrier Guardrail W-Beam Galvanized Panels, Corten W-Beam Panels CONSTRUCTION STANDARD NO. C MEASUREMENT INFORMATION: Guardrail measurement will start at the first guardrail post and end at the last post, except where bolted to a parapet wall, in which case it will begin/end at the point of the connection to the parapet wall. The first (several) post(s) will be part of the guardrail end treatment, however for measurement purposes, the rail portion of the end treatments will be considered as part of the guardrail panels. There are sections of W-Beam guardrail that transition to/from Thrie-Beam guardrail. In these instances, measurement of W-Beam guardrail panels will stop/start at the point of transition to/from Thrie-Beam guardrail. Measurement of guardrail starts and stops at each end of the barrier when sections of guardrail are interrupted by sections of barrier. MEASUREMENT LOCATION AND FREQUENCY: GPS readings shall be captured at the front face of each end of guardrail on tangent (straight) sections of guardrail. Multiple points must be recorded on curves at approximately 500' 600 intervals, more often as appropriate on tight radius curves (interchanges, etc). Start/end measurement at the first and last guardrail post (wood or steel) (Guardrail End Treatment) or connection point to barrier wall. In circumstances where GPS readings cannot be captured, (generally due to atmospheric conditions or obstructions) measurements shall be captured either by electronic measuring devices, measuring wheels or other measuring devices. When saving a record without a GPS reading, you will need to enter an accurate milepost and offset. MEASUREMENT UNIT: Guardrail is a linear feature with the measurement in Lineal Feet. When multiple GPS readings are recorded, length will automatically be computed when the record is saved. Where physical measurement must be taken, enter the quantity, to the nearest foot, on the hand-held device. SUPER ASSET: Guardrail is one of the few assets that are designed as a Super Asset. This means that the collection and quantification of multiple assets, in one record, is possible. This represents a considerable time savings in data collection. Because a GPS point is collected at the beginning and end of a guardrail installation (where the Guardrail End Treatments are located) they share common GPS points. The Leading Guardrail End Treatment and the beginning of the guardrail share a common GPS point. The same applies to the Trailing Guardrail End Treatment, unless the guardrail transitions to Thrie Beam Guardrail. Collection of a single Guardrail End Treatment may also still be accomplished under the Guardrail End Treatment feature. Note: When searching the collection device for a guardrail end treatment that has been created under the Super Asset guardrail record, you must search under Guardrail End Treatment instead of Guardrail. GENERAL TAB INFO: You will also be asked to complete the following information on the General Tab: Post Type - Select from drop-down. Selections are Wood, Steel or Both. IMPORTANT DO NOT CONSIDER THE STEEL POSTS THAT ARE PART OF THE END TREATMENT IN MAKING THE POST TYPE DETERMINATION. Post types, excluding the posts that are part of the end treatments should all be of one type. The selection of Both should be a rare occurrence. 1

20 Roadway Barrier Guardrail W-Beam Galvanized Panels, Corten W-Beam Panels SUPER ASSET TAB: Allows the collection of Guardrail End Treatments within the Guardrail feature record. To collect Guardrail End Treatment, check appropriate box or boxes Beg or End Guardrail End Treatment, then select the appropriate end treatment from the dropdown boxes. If guardrail transitions to a Thrie Beam Guardrail, or a different ramp on a TI, do not list a End Guardrail End Treatment, or vice-versa. IDENTIFICATION: Guardrail will usually fall within the following four types. Should you encounter guardrail in your data collection activities that does not conform to the following examples, collect the guardrail type as a Miscellaneous type and enter any distinguishing information in the Notes section of the Common Tab on the data collection device. In addition, take several photos, from different angles and the photos, along with the route number and milepost to Bob Harris ([email protected]). Galvanized W-Beam Guardrail Corten W-Beam Guardrail 2

21 Roadway Barrier Guardrail Galvanized Thrie-Beam Panels, Corten Thrie-Beam Panels CONSTRUCTION STANDARD NO. C MEASUREMENT INFORMATION: There are sections of Thrie-Beam guardrail that transition to/from W-Beam guardrail. In these instances, measurement of Thrie-Beam guardrail panels will stop/start at the point of transition to/from W-Beam guardrail. Measurement of guardrail starts and stops at each end of the barrier when sections of guardrail are interrupted by sections of barrier. IDENTIFICATION: Galvanized Thrie-Beam Corten Thrie-Beam 3

22 Roadway Barrier Guardrail End Treatments Various End Treatments CONSTRUCTION STANDARD NO. See appropriate Drawing number(s) with each End Treatment Type. MEASUREMENT LOCATION AND FREQUENCY: GPS readings shall be captured center of the face of each end treatment, including both the leading and trailing end treatments. In circumstances where GPS readings cannot be captured, (generally due to atmospheric conditions or obstructions) the record shall be completed and saved without the GPS readings. When saving a record without a GPS reading, you will need to enter an accurate milepost and offset. MEASUREMENT UNIT: Guardrail End Treatments are a point feature. The measurement unit is each. The proper identification of the Guardrail End Treatment is very important for the quality of the inventory. GENERAL TAB INFO: No entry required for this feature. IDENTIFICATION: Identification of Guardrail End Treatments can be confusing. Some types are quite apparent while the difference in others can be relative minor. With some practice, the ability to correctly identify the various end treatments will become much easier. Should you encounter Guardrail End Treatments, in your data collection activities, which do not conform to the following examples, collect the end treatment as a Miscellaneous type and enter any distinguishing information in the Notes section of the Common Tab on the data collection device. In addition, take several photos, from different angles and the photos, along with the route number and milepost to Bob Harris ([email protected]). FLARED END SECTION 4

29 Roadway Barrier Barrier Various CONSTRUCTION STANDARD NO. C MEASUREMENT INFORMATION: Barrier measurement will start at the leading end of the barrier and end at the trailing end of barrier. MEASUREMENT LOCATION AND FREQUENCY: GPS readings shall be captured at each end of barrier on tangent (straight) sections of barrier. Multiple points must be recorded on long sweeping curves at approximately 400' 600 (or as appropriate) intervals, more often on tighter radius curves and interchanges. Start/end measurement at the leading and trailing end of the barrier. In circumstances where GPS readings cannot be captured, (generally due to atmospheric conditions or obstructions) measurements shall be captured either by electronic measuring devices, measuring wheels or other measuring devices. When saving a record without a GPS reading, you will need to enter an accurate milepost and offset. MEASUREMENT UNIT: Concrete Barrier is a linear feature with the measurement in Lineal Feet. When multiple GPS readings are recorded, length will automatically be computed when the record is saved. Where physical measurement must be taken, enter the quantity, to the nearest foot, on the hand-held device. GENERAL TAB INFO: No entry required for this feature. IDENTIFICATION: The following photos will help in identifying the various types of barriers. CONCRETE BARRIER 11

30 Roadway Barrier Barrier Various CONCRETE BARRIER (continued) Concrete Barrier is often found separating freeway lanes going in opposite directions, but can also be found separating roadways going in the same direction. Where concrete barrier separates roadways going in opposite directions (medians), record the feature in the cardinal direction. Be careful not to overlook a barrier feature because it looks like something else. Note on below, left concrete barrier AND chainlink fence (2 separate features) and right concrete barrier AND sound wall. CONCRETE BARRIER WITH GLARE SCREEN CONSTRUCTION STANDARD NO. C Concrete Barrier with Glare Screen is a feature that is usually found on freeways, separating traffic traveling in opposing directions. Where concrete barrier with glare screen separates roadways going in opposite directions (medians), record the feature in the cardinal direction. The glare screen serves two purposes reducing the glare of approaching headlights and limiting visual distractions. 12

31 Roadway Barrier Barrier Cable Barrier CABLE BARRIER Cable Barrier is a feature that is often times found separating traffic traveling in opposing directions on freeways, much the same as concrete barrier and concrete barrier with glare screen, though it can also be found separating roadways (such as frontage roads) traveling in the same direction. It may also be found as a single strand barrier limiting access to roadways. Cable Barrier may consist of 1, 2, 3 or 4 cable strands. 13

32 Roadway Barrier Barrier Cable Barrier CABLE BARRIER (continued) Single Strand Cable Barrier CHAIN LINK CABLE BARRIER CONSTRUCTION STANDARD NO. - Various The chain link cable barrier feature is often found in locations where its purpose is to prevent vehicles from entering a location where there is a sudden change (drop) in elevation. It may also be found at a T intersection, preventing vehicles from entering an adjacent roadway, as well as other locations. Where this barrier exists in a median, protecting grade changes, collect the feature in the direction of the traffic flow for which it provides protection. See note/example below. WB I-10 EB I-10 This Chain Link Cable Barrier is protecting traffic traveling in the EB direction; therefore it would be collected as an EB median feature. 14

33 Roadway Barrier Barrier Chain Link Cable Barrier (continued) END BARRIER SECTION 15

34 Roadway Barrier Barrier End Treatments Various End Treatments CONSTRUCTION STANDARD NO. See appropriate Drawing number(s) with each End Treatment Type. MEASUREMENT LOCATION AND FREQUENCY: GPS readings shall be captured center of the face of each Barrier End Treatment. In circumstances where GPS readings cannot be captured, (generally due to atmospheric conditions or obstructions) the record shall be completed and saved without the GPS readings. When saving a record without a GPS reading, you will need to enter an accurate milepost and offset. MEASUREMENT UNIT: Barrier End Treatments are a point feature. The measurement unit is each. GENERAL TAB INFO: You will also be asked to complete the following information on the General Tab: No. of Barrels/Bays/Cushions - Select from drop-down as appropriate IDENTIFICATION: Identification of Barrier End Treatments should be less confusing than the guardrail end treatments. There are fewer types and the differences between Barrier End Treatments are great. Should you encounter Barrier End Treatments during your data collection activities that do not conform to the following examples, collect the end treatment as a Miscellaneous type and enter any distinguishing information in the Notes section of the Common Tab on the data collection device. In addition, take several photos, from different angles and the photos, along with the route number and milepost to Bob Harris ([email protected]). QUAD GUARD Construction Drawing ard_appr.pdf The Quad Guard Barrier End Treatment is quite easy to identify, although its overall length, width and shape may be different from location to location, as seen below. Note that the name of the end treatment is molded into the crash cushion cartridge 16

35 Roadway Barrier Barrier End Treatments Various End Treatments (continued) QUAD GUARD (continued) Note the Quad Guard has 4 corrugations (ribs) verses the GREAT Barrier System which has 3. REACT 350 (Reusable Energy Absorbing Crash Terminal) Construction Drawing 0_appr.pdf 17

36 Roadway Barrier Barrier End Treatments Various End Treatments (continued) REACT 350 (Reusable Energy Absorbing Crash Terminal) (continued) This portion of the feature is located at the back of the feature. This stamp, REACT 350, is located on previous photo. G-R-E-A-T Barrier System Note that the G-R-E-A-T System has only 3 corrugations (ribs), though similar in appearance (at first glance) to the Quad Guard. This system is not one which has seen a great deal of use in Arizona, although they have been used occasionally. If you locate one of these features, please provide the information and notification listed in the Identification paragraph on the first page of the Barrier End Treatment section. 18

37 Roadway Barrier Barrier End Treatments Various End Treatments (continued) SANDWICH HEX-FOAM SYSTEM The SANDWICH Hex-Foam System is another system that has not seen much use in Arizona. As with the GREAT System, if you locate one of these features, please provide the information and notification listed in the Identification paragraph on the first page of the Barrier End Treatment section. 19

38 Roadway Barrier Barrier End Treatments Various End Treatments (continued) ADIEM II BARRIER END TREATMENT Construction Drawing: SAND BARREL BARRIER END TREATMENT There are various sets of standard drawings for sand barrels, depending on the manufacturer. In the photos above, Sand Barrels appear on both sides of a median obstruction. Each feature will be captured in the direction of approach in this case, 1 Feature of 12 sand barrels in the eastbound direction, median side and 1 Feature of 12 sand barrels in the westbound direction, median side. 20

39 Roadway Barrier Barrier End Treatments Various End Treatments (continued) SAND BARREL BARRIER END TREATMENT (continued) The photo above shows a typical sand barrel installation for an obstruction on the right side of the road. Typical installations usually include sand barrels. WATER-FILLED BARRIER END TREATMENTS The above pictured water-filled barriers are located on I-17 at the Daisy Mountain and Anthem interchanges. These are only one type of water-filled containers that you may find on the Arizona highway system. Should you encounter other types of water-filled barrier end treatments during your data collection activities, record them under this feature and take several photos, from different angles and the photos, along with the route number and milepost to Bob Harris ([email protected]). 21

40 Roadway Barrier Barrier End Treatments Various End Treatments (continued) SMART CUSHION IMPACT ATTENUATOR CONSTRUCTION STANDARD NO. IDENTIFICATION: At first glance, the Smart Cushion Impact Attenuator looks very similar to the Quad Guard End Treatment. The immediate difference you will notice is the absence of cushions inside the crash attenuator. In lieu of cushions, the Smart Cushion Attenuator utilizes hydraulics to absorb the crash energy. 22

41 Roadway Barrier Handrail Handrail CONSTRUCTION STANDARD NO. No construction standards are provided due to the variety of types that may be found on the highway system. MEASUREMENT INFORMATION: Handrail measurement will start at the first post and end at the last post. Handrail is most frequently found adjacent to drainage structures, but may be found as barriers between traffic and pedestrians and on freeways on elevated planting beds. Handrail on structures (bridges) is not included in this feature. MEASUREMENT LOCATION AND FREQUENCY: GPS readings shall be captured at the front face of each end of Handrail on tangent (straight) sections of handrail. Multiple points should be recorded on curves or at directional changes in the handrail. In circumstances where GPS readings cannot be captured, (generally due to atmospheric conditions or obstructions) measurements shall be captured either by electronic measuring devices, measuring wheels or other measuring devices. When saving a record without a GPS reading, you will need to enter an accurate milepost and offset. GENERAL TAB INFO: No additional information required. MEASUREMENT UNIT: Handrail is a linear feature with the measurement in Lineal Feet. When multiple GPS readings are recorded, length will automatically be computed when the record is saved. Where physical measurement must be taken, enter the quantity, to the nearest foot, on the hand-held device. IDENTIFICATION: Note on this and the following page that handrail type and location can vary considerably. 23

42 Roadway Barrier Handrail Handrail (continued) 24

43 Roadway Drainage Pipe Openings CMP (Corrugated Metal Pipe) CONSTRUCTION STANDARD NO. C MEASUREMENT LOCATION AND FREQUENCY: GPS readings shall be captured at the top center of each end of the CMP. In cases where there are multiple down CMP s at the same location, capture the GPS reading at the center of the group of CMP s. In circumstances where GPS readings cannot be captured, (generally due to atmospheric conditions or obstructions) the record shall be completed and saved without the GPS readings. When saving a record without a GPS reading, you will need to enter an accurate milepost and offset. MEASUREMENT UNIT: CMP s are point features. The measurement unit is each opening. GENERAL TAB INFO: You will also be asked to complete the following information on the General Tab: Diameter Select from drop-down measure side to side diameter if silted-in. Erosion Treatment Select from drop-down Number of Openings Select from drop-down Inlet End Treatment Select from drop-down Outlet End Treatment - Select from drop-down IDENTIFICATION: Identification of CMP s is fairly simple. They also bear some similarities to CMPA (Corrugated Metal Pipe Arched) and Structural Plate large pipe which comes in pieces which must be bolted together to form the pipe). The end treatment of the pipe must also be identified and recorded. Some examples are provided below. CMP with Flared Metal End Section Safety Traversable End Section 25

89 Roadway Shoulder Roadway Shoulders Various Shoulder Types MEASUREMENT INFORMATION: Measurement of Roadway Shoulder will start at the beginning of the shoulder section, either paved or unpaved, for the section or roadway to be covered and will terminate at the end of the section. Roadway Shoulder data IS NOT collected in guardrail sections, in roadway cuts or in areas where cut ditches extend beyond the end of the cut. Generally Collect shoulder data in curb and gutter areas where there is 5 or more of unpaved surface behind the curb. Do not Collect shoulder data in curb and gutter areas where there is sidewalk immediately adjacent to the curb. MEASUREMENT LOCATION AND FREQUENCY: GPS readings shall be captured at each end of the shoulder on tangent (straight) sections of the feature. Multiple points must be recorded on curves at appropriate intervals. The GPS Readings may be collected at the edge of the pavement, from the vehicle, utilizing external antenna(s). In circumstances where GPS readings cannot be captured, (generally due to atmospheric conditions or obstructions) measurements shall be captured either by electronic measuring devices, measuring wheels or other measuring devices. When saving a record without a GPS reading, you will need to enter accurate milepost information. MEASUREMENT UNIT: Lineal Feet. When multiple GPS readings are recorded, length will automatically be computed when the record is saved. Where physical measurement must be taken, enter the quantity, to the nearest foot, on the hand-held device. GENERAL TAB INFO: No additional information is required. IDENTIFICATION: Identification of the Shoulder is based on either a paved shoulder or an unpaved shoulder. Paved Surface Shoulder Roadway Cross Section The roadway surface includes the travel lanes and the paved area behind the shoulder stripe. The shoulder starts at the edge of pavement (Unpaved Shoulder) or where the level roadway surface begins to break at a downward angle (Paved or Unpaved Shoulder). 71

90 Roadway Shoulder Roadway Shoulders Various Shoulder Types (Continued) UNPAVED SHOULDER Unpaved Shoulder data IS collected in curb sections where there is no sidewalk or other paved features immediately behind the curb. PAVED SHOULDER Paved shoulder is collected where the shoulder, from the edge of the roadway surface, is paved for a distance of 5 feet from the edge of the roadway. Where MILLINGS have been placed on shoulders AND shot with asphalt and rolled, these areas will be considered paved. 72

91 Roadway Surface Turnout Turnout CONSTRUCTION STANDARD NO. - VARIOUS MEASUREMENT LOCATION AND FREQUENCY: A single GPS reading shall be captured at the center (when possible) of the Turnout, at the roadway shoulder, in line with the edge of pavement on either side of the turnout. In circumstances where GPS readings cannot be captured, (generally due to atmospheric conditions or obstructions) the record shall be created and saved without the GPS reading. When saving a record without a GPS reading, you will need to enter an accurate milepost and offset. Local intersecting streets will be considered as turnouts. Intersecting interstate or state highways, frontage roads or ramps on interchanges will NOT be considered Turnouts. Curb depressions for driveways are NOT considered turnouts MEASUREMENT UNIT: Point feature. A single GPS reading is to be recorded. SUPER ASSETS: Turnouts are one of the few assets that have been designed as a Super Asset. This means that the collection and quantification of multiple assets, in one record, is possible. This represents a considerable time savings in data collection. Turnouts often times have additional features located with them, such as cattleguards and hinged gates (locked or unlocked), which can be associated with the Turnout GPS point. The Super Asset makes it possible to collect all three feature types in one record. A GPS point is generally collected at the center of the Turnout, at the roadway shoulder, in line with the edge of pavement on either side of the turnout. Though a point is not collected at the cattle guard or gate; they can be easily located on the turnout. The tradeoff, in this case, of accuracy for the sake of time, has little impact on the data collected. If either hinged gates or cattleguards are located at locations other than turnouts, these features can still be collected, but must be collected as individual assets under Roadway Roadside Category. On the GPS data collection device, when searching for either a cattle guard or hinged gate that has been created under the Super Asset Turnout record, you must look under either the cattle guard or hinged gate features under the Roadway Roadside Category. SUPER ASSET TAB: Allows the collection of either hinged gates or cattleguards, or both, within the same record as the Turnout. Select the appropriate features form the dropdown boxes. In the case of cattle guards, select the number of grills from the dropdown box. Enter the appropriate number of locked or unlocked gates. DO NOT RECORD GATES IN PRIVATELY OWNED FENCE. GENERAL TAB INFO: No entries are required on the General Tab IDENTIFICATION: Select the type of turnout to be collected, either paved or unpaved. Only enter turnouts which are constructed and maintained. Do not collect areas where roads (turnouts) are established simply by repeated use. A turnout can be defined as a constructed or improved access to an improved intersecting street or road, either paved or unpaved. 73
