Pavement Health Track Remaining Service Life (RSL) Forecasting Models, Hands-On Workbook

Chapter 3 - Working with Highway Data

Objective: Become familiar with the features of the PHT tool for reading, viewing, editing, and selecting highway data records for the PHT analysis.

Specifics: The Highway Data file is a user-provided data file which describes several different characteristics and variables associated with each road section in the user’s system.

The characteristics include:

  • identification information such as State, County, Section ID;
  • pavement characteristics, such as pavement type, thickness, roughness, rutting, faulting, cracking, etc.
  • traffic/capacity data such as AADT, speed limit, peak capacity, percent trucks and future year AADT forecasts.

Formatted similar to the highway performance monitoring system (HPMS 2010) data, the data needs to be in the same order and same structure as HPMS. The source highway data can also be in other formats such as comma-delimited CSV or DBF files or other ODBC connective data sources that can be manually mapped to the PHT database schema.

Use: The PHT tool provides very powerful features to allow a user to view and select highway sections for analysis both manually and automatically using SQL queries and GIS maps.

Tasks:

  1. Read highway data from an HPMS 2010 formatted file.
  2. View and manipulate the highway data.
  3. Select records for analysis.
  4. Create copies of the highway data.

Three screen shots show progressive stages in a study command. In the first screen shot the button icon to read HPMS is highlighted by the number 1. Click the Read HPMS Database button to select the source file. In the second screen shot a folder icon is selected, which is highlighted by the number 1a. Browse to the Sample directory on the PHT installation CD. In the third screen shot, the selected file, which is highlighted by the number 1b, is shown in a new window, and the button icon to open is highlighted by the number 1c. (Click Open)

Two screen shots show progressive stages in a study command. In the first screen shot a file is selected, and the button icon to open file is highlighted by the number 2. After the HPMS data is read, it will be displayed in the Settings tree under the Databases branch. Click the Open button to display the highway data. The highway data is display in a table that can be browsed, filtered, and edited. In the second screen shot data are presented in columns. A column headed by the term select is highlighted to indicate that the default mode is selection of all highways for analysis.

Two screen shots show progressive stages in a study command. In the first screen shot a column headed by the term select is highlighted by the number 3 to indicate that selection of any cell makes the entire column active. Select any cell in the f_Select column to make it the active column. The button icon for fill is highlighted by the number 4. Click the Fill button. In the second screen shot the field for the fill option is highlighted by the number 4a to indicate that the word false has been typed. The button icon for apply is highlighted by the number 4b to indicate the operation is to be carried out. (Click Apply)

Two screen shots show progressive stages in a study command. In the first screen shot a column headed by the term select is highlighted to indicate that no cells are marked for selection and analysis. The button icon for fill is highlighted by the number 5.  Click the Fill button again.In the second screen shot the field for the fill option is highlighted by the number 5a to indicate that the word true has been typed. Under fill options, the radio button for fill records that match the filter query is selected. Under the filter wizard, text that is input in the criteria column is highlighted by the number 5c to indicate the s_route_ID equals 35. The button icon for apply is highlighted by the number 5d to indicate the operation is to be carried out. (Click Apply)

A screen shot shows the next stage in a study command. The highway data item is selected in the settings tree, which is highlighted by the number 6. The button icon for the copy command is highlighted by the number 7. Click the Copy button to create a copy of the selected highway data set.

A screen shot shows the next stage in a study command. The copied file is highlighted, with the annotation that only highway sections associated with the Route ID 35 are resident in the copy. A copy of the highway data has been created and displayed in the settings tree. Only the highway sections that were selected are included in the copy so, in this case, only the highway sections whose Route ID is 35 are part of the new highway data set.
