Chapter 9 Understanding Analysis Results

This chapter addresses the primary output generated by HERS-ST: System Conditions, Improvement Statistics and Section Conditions.

Types of Analysis Results

The HERS-ST analysis provides three types of results as shown below. These three types of data along with the settings used to produce them comprise an analysis Scenario. Each time you run the HERS-ST analysis, a new Scenario is created and added to the current Workset. The Workset may contain multiple Scenarios. Along with the results data, the Scenario contains a read-only copy of the highway data, State improvement data, and the Control and Parameter settings used in the analysis. The Output settings serve only as a directive to govern what results are captured. These settings do not affect the content of the data therefore, are not included as part of the Scenario.

Results	Contains
System Conditions	Initial conditions of the highway system and its conditions after each funding period.
Improvement Statistics	Aggregate statistical information about the costs, values, and benefits of improvements on the highway system.
Section Conditions	Initial condition of each highway section and its condition at the end of each funding period.

If you perform a multiple run analysis such as a Minimum BCR or a sensitivity or continuation run, HERS-ST produces analysis output comprised of multiple results sets. The results sets produced correspond to the individual runs generated. Each result set maintains a copy of the Control and Parameter settings it used along with the result data.

The Scenario is displayed on the Results tab of the Workset tree (Figure 9-1).

Figure 9-1. Workset Tree (Results).

System Conditions

The System Conditions viewer is displayed by double-clicking the system conditions branch in the Workset tree (Figure 9-1), or selecting the Display item in its popup menu.

If you chose not to capture the system conditions data in the Output settings, then no branch for this data type will appear in the Workset tree.

General Tab

The General tab of the system conditions viewer shows the name and brief description (Figure 9-2). The last user to modify the data and a corresponding timestamp are also displayed.

Figure 9-2. System Conditions (General).

Categories Tab

The Categories tab of the system conditions viewer (Figure 9-3) shows a table that summarizes all of the system conditions information for each functional class with rural and urban subtotals and an overall total. The initial system conditions and the conditions after each funding period are provided. Expand any period to display all of the system condition categories for that period.

The actual list of categories that are displayed in the table is controlled by the Output settings. Only categories that you have chosen to capture will appear in this table.

Figure 9-3. System Conditions (Categories).

The Categories table can be organized two ways. You can select how you want to view the data using the option buttons at the bottom of the screen. By default, the system conditions data are always initially organized by funding period. Table 9-1 describes the categories provided in this table.

• View by Funding Period. This organization places all the categories for each funding period together and makes it easy to view all the conditions of the highway system after each funding period.
• View by Category. This organization places the information from each funding period for each category together and makes it easy to view how the conditions from a category change over time.

Mileage Deficiencies Tab

The Mileage Deficiencies tab of the system conditions viewer (Figure 9-4) shows a table that presents information about the various deficiencies in the highway system expressed as a percentage of overall miles. The information is organized by functional classification for the initial system conditions and for the conditions at the end of each funding period. The deficiency thresholds defined in the Parameter settings determine if a highway section is deficient and thus included in this table.

The Mileage Deficiencies table can be organized two ways. You can select how you want to view the data using the option buttons at the bottom of the screen. By default, the mileage deficiencies data are always initially organized by funding period. Table 9-2 describes the categories provided in this table.

• View by Funding Period. This organization places all the categories for each funding period together and makes it easy to view all the mileage deficiencies of the highway system after each funding period.
• View by Category. This organization places the information from each funding period for each category together and makes it easy to view how the mileage deficiencies for each category change over time.

Figure 9-4. System Conditions (Mileage Deficiencies).

The actual list of deficiencies that are displayed in the table is controlled by the Output settings. Only deficiencies that you have chosen to capture will appear in this table.

VMT Deficiencies Tab

The VMT Deficiencies tab of the system conditions viewer (Figure 9-5) is identical to the mileage deficiencies tab except that its information is expressed as a percentage of VMT rather than miles. The information is organized by functional classification for the initial system conditions and for the conditions at the end of each funding period. The deficiency thresholds defined in the Parameter settings determine if a highway section is deficient and thus included in this table.

The VMT Deficiencies table can be organized two ways. You can select how you want to view the data using the option buttons at the bottom of the screen. By default, the VMT deficiencies data are always initially organized by funding period. Table 9-3 describes the categories provided in this table.

If you chose not to capture the improvement statistics data in the Output settings, then no branch for this data type will appear in the Workset tree.

Improvement Statistics

The Improvement Statistics viewer is displayed by double-clicking the improvement statistics branch in the Workset tree (Figure 9-1), or selecting the Display item in its popup menu. This information provides a summary of data about the improvements selected during each funding period and data expressing the effects of the selected improvements on the improved sections during the last year of the funding period.

The estimates of the costs and benefits of implementing improvements are presented as the annual costs and benefits in the last year of the funding period that result from implementing all improvements in the middle of the period. As a result, although improvements are selected only if they produce overall benefits, some improvements may increase certain types of costs during a portion of the analysis, which is shown as a negative benefit in the table.

General Tab

The General tab of the improvement statistics viewer shows the name and brief description (Figure 9-6). The last user to modify the data and a corresponding timestamp are also displayed.

Figure 9-6. Improvement Statistics (General).

Statistics Tab

The Statistics tab of the improvement statistics viewer (Figure 9-7) shows a table that summarizes all of the aggregate statistical information for each functional class with rural and urban subtotals and an overall total. Statistics for each improvement type for each funding period and for the entire analysis period are provided. Expand any period to display the statistics for all the improvement types for that period.

The HERS-ST improvement types are discussed in more detail in Chapter 6.

Not all of the statistical types include information for the analysis period.

Figure 9-7. Improvement Statistics (Statistics).

The various types of available statistical information are shown in the list at the top of the window. Here, you pick which statistical information is displayed in the table.

The actual statistical categories that are available are controlled by the Outputs settings.

The categories described in Table 9-4 provide statistical information about the improvements HERS-ST has selected for implementation during each funding period and for the overall analysis period. These topics generally quantify the aggregated selected improvements.

Table 9-4. Improvement Statistics Categories.

Category	Acronym	Description
Total Initial Cost	INICOST	Total initial cost of the selected improvements.
Lane-Miles Improved	LMIMP	Total number of lane-miles added by the selected improvements.
Average BCR	AVEBCR	Average benefit-to-cost ratio of the selected improvements.
Miles Improved	MILEIMP	Total number of highway miles improved.
Lane-Miles Added	LMADD	Total number of lane miles added by the selected improvements.
Capital Requirements by IBCR Range	CAPRQMTIBCR	Capital required to implement the selected improvements.
Sample Sections by IBCR Range	SAMPSECIBCR	Total number of sample sections affected by the selected improvements.
Miles Improved by IBCR Range	MILEIMPIBCR	Total number of highway miles improved.
Travel-Time Benefits by IBCR Range	TRVTMIBCR	Travel-time benefits to user-benefits ratios. This data express the percentage of total user benefits that are derived from the travel-time savings.

The last four categories are broken down into seven different incremental ranges of benefit-to-cost ratios (IBCRs). These items provide a profile of the benefits returned per the capital invested in each improvement type.

Although improvements are selected only if they produce an overall benefit, at least some selected improvements may increase certain types of costs, which appear as negative benefits.

The Travel-Time Benefits category demonstrates the complexity that often accompanies interpretation of the HERS-ST output. At first glance, the presence of both negative percentages and percentages greater than 100% in the data might appear unreasonable.

• Negative percentages can arise when the total user benefits are negative. This would usually be driven by safety benefits, which are often negative, reflecting the greater number of accidents at high speed. An improvement with a negative user benefit may be selected when other benefit components such as agency costs, residual value, and emissions benefits are large enough to produce a positive overall benefit.
• Similarly, a significant safety dis-benefit could result in a positive sum of total user benefits being less than the travel-time benefit. This produces travel-time benefits that are greater than 100% of the total user benefit.

The statistical categories shown in Table 9-5 estimate the costs and benefits of implementing the selected improvements. They are presented as the annual costs and benefits in the last year of each funding period that result from implementing all improvements in the middle of the period. These categories do not produce a result for the overall analysis period.

Table 9-5. Improvement Statistics Categories.

Category	Acronym	Description
Total Benefits	TOTBEN	Total benefits from implementing all the selected improvements.
Maintenance Cost Savings	MNTSAV	Total maintenance cost savings as a result of the selected improvements.
User Benefits	USRBEN	Total user benefits, which include travel-time savings, operating cost savings and safety benefits.
Travel-Time Savings	TRVTMSAV	Total travel-time savings from the improvements.
Operating Cost Savings	OPCSTSAV	Total vehicle operating-cost savings from the selected improvements. On some sections, the vehicle operating costs will show a net increase due to higher operating speeds, which may appear as a negative net savings.
Safety Benefits	SAFBEN	Total safety benefits from the improvements. The increase in traffic on improved sections may result in more safety incidents, which may appear as a negative benefit.
Crashes Avoided	CRSHAVD	Total number of crashes that were avoided from implementing all the selected improvements.
Injuries Avoided	INJAVD	Total number of injuries that were avoided from implementing all the selected improvements.
Lives Saved	LIVES	Total number lives that were saved from implementing all the selected improvements.
VMT of Improved Sections	VMTIMP	Total vehicle miles traveled on the improved sections. The VMT forecasts can be used in conjunction with the estimates of costs and benefits to derive estimates of costs and benefits per vehicle mile.
Pollution Damage Savings	POLTSAV	Total impact of pollution damage from the selected improvements.

The improvement statistics table can be organized two ways. You can select how you want to view the data using the option buttons at the bottom of the screen. By default, the improvement statistics data are always initially organized by funding period.

• View by Funding Period. This organization places all the improvement types for each funding period together and makes it easy to view all the statistics for the improvements recommended for each funding period.
• View by Improvement Type. This organization places the information from each funding period for each improvement type together and makes it easy to view the statistics for an improvement type over a period of time.

Section Conditions

The Section Conditions viewer is displayed by double-clicking the section conditions branch in the Workset tree (Figure 9-1), or selecting the Display item in its popup menu.

If you chose to not capture the section conditions data in the Output settings, then no branch for this data type will appear in the Workset tree.

For each funding period, HERS-ST produces results data describing the condition of each section at the end of the funding period along with information about all improvements that have been selected and the effects of these improvements. Additionally, HERS-ST produces similarly formatted data that reports the initial conditions.

General Tab

The General tab of the section conditions viewer shows the name and brief description (Figure 9-8). The last user to modify the data and a corresponding timestamp are also displayed.

Figure 9-8. Section Conditions (General).

Sections Tab

The Sections tab of the section conditions viewer (Figure 9-9) provides a table that displays the initial conditions of the highway sections as well as their conditions at the end of each funding period. Expand any period to display the condition for all the highway sections for that period.

Each column in this table is defined in Table 9-6.

The actual highway sections included here are controlled by the Output settings. Only sections that you have chosen to capture will appear in this table.

Figure 9-9. Section Conditions (Sections).

You can hide and re-size the columns of the section conditions table to modify its layout to your preference. The table provides layout formatting capability through popup menus. You activate these menus by RIGHT-clicking on individual records or on the column headers.

A secondary viewer window is available for viewing the conditions for a single highway section in a vertical format (Figure 9-10). You activate the section viewer window by double-clicking a record in the table or by selecting the View item in the popup menu. This window floats above all other windows and tracks with the active row selected in the section conditions table.

The rows displayed in the Section Conditions viewer match the format of the columns displayed in the Section Conditions table. Columns that are hidden in the layout of the Section Conditions table will not appear in this window.

Figure 9-10. Section Conditions Viewer.

This window uses abbreviations defined in Table 9-6 for the field names.

Menus

By RIGHT-clicking on the table body or column headers, you activate popup menus that allow you to sort, hide and show columns of data, and to manipulate the table (Figure 9-11).

Figure 9-11. Section Conditions Table Menu.

• Sort columns in either ascending or descending order.
• Hide, show and get on-line help for columns or groups of columns.
• Display the Section Viewer.
• Save and Restore the current table layout.
• Copy records to the clipboard.
• Preview the table as it will print.

Configuring the Table Layout

You can configure the presentation layout of the section conditions table. For example, you might hide unwanted columns or groups of columns or adjust column widths. You can save your layouts with specific names to a library for future use by selecting the Table/Save Layout item in the popup menu. To restore a previously layout, select it by its name from the Restore Layout item in the popup menu.

To re-size a column, drag the column divider in the header to the desired width. Use the popup menus to hide and show unwanted columns or groups of columns.

Sorting Records

You can sort the records in the section conditions table by column by using the Sort Record item in the popup menu and selecting to sort in ascending or descending order. When sorting, the records will be sorted within their respective hierarchal groupings.

Synchronizing Records

Each record in the section conditions data corresponds to a record in the highway data. You can synchronize these two data sets so that when both the highway data and section conditions data windows are displayed, the selected record of the section conditions data tracks with its counterpart in the highway data and vice-versa. Synchronizing is enabled under the View menu on the main application window.
