Enhancement of the Pavement Health Track (PHT) Analysis Tool Final Report

Expanded Reporting Module

Introduction

The objective of this task was to expand the current report wizard interface in include a wider variety or reporting options and take advantage of the extended Chart template features implemented in Task 10. The HPMS and RSL data produced is tabular in nature. The statistical data produced by the analysis is often better represented in a more graphical format such as a graph or chart, and geographical information is better visualized in a GIS map.

Graphical User Interface

The expanded Report Wizard provides an automated process to generate statistical charts and thematic maps useful to visualize the results of the analysis. The graphical user interface for the Report Wizard window is shown in Figure 88.

A screen shot shows the PHT Report Wizard, where the user can input the report title, select a PHT Analysis, select a template from the Wizard, and select themes and thresholds for the report.

A title must be provided for the report. To avoid confusion later, the report title should be both descriptive and unique. A set of PHT analysis results must also be selected to provide the basis for the report content.

A list of theme options is provided that determines the purpose of the report. When a theme option is selected, a suggested list of threshold values is automatically provided that defines groupings for the reports information. This is only a suggested list and can be edited by the user as necessary. Each threshold must specify a limit value for its range, followed by a textual description of the data group that the threshold is defining. The limit values can have two meanings as follows:

  • Individual Value. The data in this grouping must equal the limit value. This setting is useful when the theme is based on an enumerated value, such as the function system.
  • Value Range. The data in this grouping must lie within the range defined by the upper limit value inclusively and the previous threshold's upper limit value exclusively; for the first threshold, the range is defined as less-than limit value inclusively. When using this setting, the limit values for each subsequent threshold must always increment in value.

The Report Wizard can generate a statistical chart, a thematic map, or both together using the same settings. When the report is generated, it is automatically added to the document library and the current Study.

Statistical Charts

Statistical charts are used to create complex graphs that illustrate quantitative information generated by the PHT analysis. Extensive formatting features are available to create many types and styles of charts that can be saved to a template library for reuse. Check the Statistical Chart checkbox to instruct the wizard to generate a chart report. An example of a statistical chart is shown in Figure 89.

A screen shot shows a window under the New Report tool, where the user can preview the chart related to the quantitative analysis in the report. The example shows a statistical chart.
Figure 89. Statistical Chart Example

A number of options are available when generating a statistical chart report:

  • Multiply section length by the expansion factor. This option will instruct the wizard to multiply the length of the highway section by its expansion factor when determining its overall total length. If no expansion factor is provided in the data, then the unmodified section length will be used. This option is useful when you have a small number of samples that represent a large number of miles and you want the report to more accurately represent the actual highway miles in the theme group.
  • Show mileage as a percent. This option will instruct the wizard to determine the total number of miles in the data set and calculate the overall percent of miles included in the theme group to be used in the chart rather than actual miles.
  • Disaggregate by surface type. This option will instruct the wizard to disaggregate the data for each theme group into sub-groups by the pavement surface type. This option in not available for thematic maps.
  • Disaggregate by function system. This option will instruct the wizard to disaggregate the data for each theme group into sub-groups by the function system. This option in not available for thematic maps.

When displaying multiple charts you have the option to display them arranged as wither as Tabbed or Stacked. The tabbed feature has the advantage of maximizing the amount of screen space available to display each chart, but only displays one chart at a time, while the stacked feature allows you to view all the charts at once, but limits the amount of space available to display each chart.

The chart appearance can be customized using the chart properties window; simply RIGHT-click anywhere in the chart area window to activate the properties dialog for the chart. Settings include color and shading, 3D effects, chart types, legend appearance, plot types, grids, axis scales and annotations, and chart labels.

A common Y-axis scale can be applied for all the charts. This is useful feature to visualize the relative values among multiple charts that show similar information with a common unit of measurement. Synchronizing the X-axis will visually align the axis positions of several charts together. This is required when using the Zoom feature and the stacked page layout.

A zooming feature is available for the X-axis. When the zooming is active, a zoom bar appears at the bottom of the chart window. You can adjust the amount of zoom and pan by dragging the beginning and ending markers to the left or right as desired. When zooming is deactivated, all zooming will be removed from the charts.

When printing the chart, the print destination can be a printer, Windows clipboard, or a bitmap file. Options are available to set the position and scaling of the chart image as desired. A preview of the printed chart is also provided.

Thematic Maps

Thematic maps are used to create complex geographical information system (GIS) maps. A GIS defined selection must be chosen from the drop-down list for the wizard to use as the source for the map. The GIS selection provides the information about the GIS shape file and how to join the PHT analysis results to the shapes defined in the file. An example of a thematic map is shown in Figure 90.

A screen shot shows the window under the My Map tool, where the user can view a map generated from inputs selected using the drop-down list. The example map shows the corridors plotted on an area map with counties delineated.
Figure 90. Thematic Map Example

Check the Thematic Map checkbox to instruct the wizard to generate a chart report. There is one option available when generating a thematic map report.

  • Apply theme only to selected sections. This option will instruct the wizard to apply the map theme only to the highway sections that are selected in the GIS selection. This option is useful when you want the map theme to be highlighted only on a sub-section of the map such as a corridor, type of functional class, or a geographical region such as a county or urban area.

The map layer is the basic component of a map. A map can have multiple layers with each layer displaying the contents of a different shape file. The order in which the layers are displayed is shown in the legend with the layer at the top appearing above all layers beneath it.

To create a selection of items from the map, click the Selection button on the toolbar and a new selection is added to the currently selected layer and displayed in the legend. The selection is highlighted with a user-defined color, line thickness and style. The drop-down menu provides three methods available to add items to the selection.

  • Select by Attributes. This option will display the query dialog where you can build a SQL query statement to select items based on their attributes. The query wizard allows you to define selection criteria to add items to the selection.
  • Manual Selection. This option allows you to manually add items to the selection by clicking on them in the GIS map. Only items that are in the currently selected map layer can be added.
  • Select by Shortest Path. This option applies to line-layers only and allows you to automatically select a map corridor between two points. If no unbroken path between the two points can be found, then no items will be added to the selection.

To view the attributes of any item in the map, click the Identify button on the toolbar and then click the item on the map. Items on any layer of the GIS map may have many attributes that describe them. These attributes are useful to create map selections and themes. The attributes for the item appear in a table under the legend.

Templates

The PHT report wizard can also automatically generated statistical charts based on a predefined template that resides in the template library. The template library is displayed by clicking on the Template tab as shown in Figure 91. The chart templates are created and formatted in accordance with design of the chart template feature discussed under Task 10.

Several predefined templates are provided with the PHT analysis tool. The following paragraphs discuss the purpose of these templates and provide an example of the chart produced by each template file.

A screen shot shows the window under the PHT Report Wizard, where the user can input the report title, select a PHT Analysis, select a template from the Wizard, and select a specific chart from the list provided.
