| 1-3 | Table 1.1: Minimum Data Reporting for Selected HPMS Products - Footnotes | 1/ Data for Lane-Miles on Rural Minor Collector, and Local roads are calculated using Summary miles times 2. Since the States are not required to report the number of through lanes on these systems, except for NHS sections, FHWA uses a multiplier of 2 for the number of lanes, to be consistent across all States. |

| 3-1 | Overview - Discussion | This data model is organized conceptually into a group of six catalogs. Each catalog groups the various datasets by type and/or function. The types of data can be categorized as: (1) geospatial data, representing various highway systems, geographic boundaries etc., (2) roadway attribute data that can be linked to a related GIS dataset, which allows the attribute data to be represented spatially via linear referencing or (3) metadata, which provides additional global information about the data. Figure 3.1 illustrates the structure of the HPMS data model. The HPMS attribute data that are submitted by the States are grouped within the Sections Catalog. The Sections dataset that is identified in this catalog stores all of the records for each data item as they are reported by the States. The Sample Panel Identification dataset stores the limits for each State's sample panel as identified by the States. The Data Item field in the Sections dataset specifies the type of record (e.g. AADT, Lane Width, etc.), with the corresponding data stored in the Value (Numeric, Text, or Date) fields. These records act independently of one another, as they indicate the properties of the attribute they portray. Furthermore, the records in both the Sections and Sample Panel Identification datasets are linked to each State's geospatial network (i.e. LRS network) via its attribute table, which is identified as the Routes dataset that is identified in the model's Shapes Catalog. Data associated with the lower functional systems (i.e. minor collectors in rural areas and local roads in all areas) are summarized and reported in the datasets identified in the Summaries Catalog. The level of data for these functional systems is commensurate with the Federal need for analyzing and reporting these data. The Estimates Catalog contains a dataset of pavement attributes that will be used as input to FHWA's pavement models. The Metadata Catalog contains data that describe the methods and tools that are used for the collection and reporting of traffic, pavement, and ramp data. The References Catalog identifies the geospatial data which will ultimately be maintained by FHWA or other non-State entities. The data in these datasets are available for use by the States throughout the year for reference. |

| 3-3 | Geospatial Component - Discussion | Furthermore, the geospatial component of the data model involves the use of a LRS, which links the HPMS attribute data to a series of shape files. Both the geospatial and attribute data contain three referencing elements that are used to perform the linkage for linear features: (1) A unique Route ID, (2) a beginning milepoint, and (3) an ending milepoint. Point features use a route milepoint in place of a beginning and ending milepoint for referencing purposes. Data Items are identified in the Point References datasets of the model's References Catalog and are linked to and spatially referenced in the same manner. For general guidance on the development of a State wide LRS, see the FHWA publication, All Public Roads Geospatial Representation Study. | Furthermore, the geospatial component of the data model involves the use of a LRS, which links the HPMS attribute data to a series of shape files.

The definition of a Maintenance Area is any geographic region of the Unites States previously designated as non-attainment pursuant to the Clean Air Act (CAA) Amendments of 1990 and subsequently re-designated to attainment subject to the requirement to develop a maintenance plan under Section 175A of the CAA, as amended. The national HPMS database is used for tracking travel for air quality assurance purposes in non-attainment and maintenance areas as required by EPA under the 1990 CAA (Section 187) and the Transportation Conformity Rule, 40 CFR parts 51 and 93. More specifically, the database is used primarily for establishing regional transportation-related emissions for transportation conformity purposes. Estimated travel based on these data is used for the calibration and validation of base-year network travel models when required for non-attainment or maintenance areas.

| 4-64 | Item 30: Percent Green Time - Guidance | Additional Guidance: Code this Data Item for all sections where right and left turn data (Data Items 12 and 13) are coded. For uncoordinated traffic actuated signals only, data can be collected when monitoring green time. Consider the surrounding environment and determine if the inventory direction of the signal would actually carry the peak flow for the intersection. Based on this approach, the value received may be an estimate depending upon the operation of the traffic signal during the peak hour. Furthermore, if the traffic signal is fully actuated, or the approach of interest is actuated, estimate the percent of green time based on the maximum green time available for that phase of operation versus the maximum cycle length. This would provide the "worst case" scenario since the volume on the actuated approach typically varies cycle by cycle. Where peak capacity for a section is governed by a particular intersection that is on the section, this Data Item shall be coded based on the percent green time at that location; otherwise code this Data Item for the predominate intersection. For traffic actuated traffic signals, use the results of a field check of several (three complete cycles) peak period light cycles to determine a "typical" green time. Ignore separate green-arrow time for turning movements. |
Additional Guidance: Code this Data Item for all sections where right and left turn data (Data Items 12 and 13) are coded. For uncoordinated traffic actuated signals only, data can be collected when monitoring green time. Consider the surrounding environment and determine if the inventory direction of the signal would actually carry the peak flow for the intersection. Based on this approach, the value received may be an estimate depending upon the operation of the traffic signal during the peak hour. Furthermore, if the traffic signal is fully actuated, or the approach of interest is actuated, estimate the percent of green time based on the maximum green time available for that phase of operation versus the maximum cycle length.

For traffic actuated traffic signals, use the results of a field check of several (three complete cycles) peak period light cycles to determine a "typical" green time. Ignore separate green-arrow time for turning movements. If this data is not available for the signalized intersections associated with a given sample section, percent green time data from other signalized intersections located on the same route, or on a similar route with similar traffic characteristics in the immediate vicinity can be used for reporting purposes. |
