Configuring a mileage report

Mileage reports are used to report mileages on routes based on their length and summarized by their characteristics. For example, there could be a mileage report that shows the miles of pavement of type of asphalt, concrete, and bituminous present in each county in a state. For more information, see Mileage reports in Roadway Reporter.

Mileage report sample

In this workflow, you'll learn how to produce a mileage report similar to the one shown above. The mileages and summaries are calculated using internal event layers that are part of the ALRS.

Data required

The following data layers are used to create the report. The layer names used here are for information only. You can use your own layer names to produce your reports.

Producing a mileage report

A mileage report can be configured using the following steps:

  1. Select the network.
  2. Select the routes.
  3. Select the summary field or fields.
  4. Add the mileage fields.

Selecting the network

The first step toward producing a mileage report is to select the route network.

  1. Open the Roadway Reporter application in your browser.
  2. Click the New Report button New Report.
    Creating reports
  3. Click the Mileage Report button Mileage Report.
    Create a new mileage report
    Create a new mileage report
  4. Click the Route Network drop-down arrow and choose a route network.
    Configuring the mileage report
  5. Type a date in the Effective Date text box for the report.

    This is the point in time that represents the state of the roadway network for which you want to report mileage.

  6. Click the Output Units drop-down arrow and choose the units for the report.

    The mileage is reported using these units.

  7. Type a value in the Number of decimals text box.

    This is the number of decimals that appear in the mileage in the report.

  8. Click Next.

Selecting the routes

The next step in the mileage report creation process is to select the routes for which the mileage will be calculated. There are two options available:

  • Spatial selection
  • Attribute selection

Spatial selection of routes

The following spatial selection tools are available to select routes:

  • Drawing bounding graphics—You can select routes by drawing graphics on the map. To do so, select a drawing tool such as Select By Rectangle Select By Rectangle and draw the rectangle graphic on the map.

    Before you draw the bounding graphic or use any other spatial filtering tools, you have the option to apply the filter in three ways:

    1. Intersects—The routes that intersect the graphic are selected.
      Routes that intersect the graphic
      Routes that intersect the graphic
    2. Completely Within—Routes completely within the graphic are selected.
      Routes that are completely within the graphic
      Routes that are completely within the graphic
    3. Touches Edge—Routes that touch the edge of the graphic are selected. If a route is within the graphic, it will not be selected because it is not touching the edge.
      Routes that are touching the edge of the graphic
      Routes that are touching the edge of the graphic
  • Selecting polygon features—You can use polygon features available in the map to select routes. For example, if you have administrative boundaries in the map, such as county or town boundaries, you can select the routes that intersect a particular county or town. To do so, select the polygon layer from the Filter layer list, click the Select Polygon tool Select Polygon, and click one or more polygons on the map.

  • Select by proximity—You can select routes within a certain distance from a point located on the map. When doing so, provide the distance and select the Units using the drop-down arrow. Click the Select By Proximity tool Select By Proximity and click the map to add a point. The routes that intersect the resulting graphic are selected.

Attribute selection

You can select the routes on the basis of attributes available in the network layer that you have selected to produce the report. If you want to select all the routes in your data to be used for reporting, do not apply any spatial or attribute filters. There are three selection methods available (only when a spatial filter is applied).

Attribute selection methods

  5. Click OK.
  6. Click Next after applying the attribute filter.

Selecting the summary field or fields

The next stage in producing the mileage report is to select a summary field. This is an optional choice. If you don't want to add summary fields to your report, skip this step by clicking Next.

  1. Click the Summary Layer drop-down arrow and choose a summary layer.
    Choosing the summary layer
    Choosing the summary layer

    1. The internal events that are part of the ALRS published in the map service the Roadway Reporting is using appears in this drop-down list.

  2. Click the Summary field drop-down arrow and choose the summary field.
    Choosing the summary field
    Choosing the summary field

    The summary field is part of the summary layer that you selected in the previous step. The mileage is summarized on the basis of unique values present in the summary field. The Display value map shows the unique values present in the summary field. You can edit the display value field in the table. You can also exclude null summary rows by checking the Exclude null summary rows from the report check box. By doing so, any gaps that exist in the linear event data will not be summarized and reported on.

  3. Click Next after choosing the summary layer and summary field.
    Exclude null summary rows from the report
  4. You can add two more levels of summary fields. For example, if you want to summarize the mileage for counties and towns, choose the county layer first and add one more summary layer by choosing the town layer.

Adding the mileage fields

After selecting the summary layer, the next step is to add the mileage fields. These mileage fields form the columns that show the mileages in the report. The mileage is calculated by using internal event layers or by using the network layer. An event layer that does not belong to the same network as chosen in the previous step, but is part of the ALRS, can be used as a mileage layer. At least one event field is required to calculate mileages for the Mileage report.

  1. Click Add Field(s).

  2. Click the Mileage Layer drop-down arrow and choose a layer for which to report mileage.
    Selecting the mileage layer
    Selecting the mileage layer

    The mileage is calculated using this layer.

  3. Choose the Single Value option.

    Use this option when you want to calculate the mileages for a single class within the attribute field. For example, within the Speed Limit field, calculating mileages where the speed limit is more than 40 miles per hour.

  4. Type the column header name in the Field name text box.

    This will be the header for the mileage column in the report.

  5. Choose to add a filter.
    • You can add an attribute filter to the mileage field. For example, if you want to report mileage for only Urban Type=Rural roads, this is where the filter would be applied.
    • A formula can also be used to calculate the mileage fields. For example, a formula for VMT (Vehicle Miles Traveled) can be calculated by multiplying AADT (Annual Average Daily Traffic) with length (the distance value available to each layer being used to report mileage against); therefore, VMT = AADT*LENGTH.

    The attribute filter page opens.

    In this example, you'll use the Urban Type internal event. The mileage will be calculated for Rural routes present in the selection set.

  7. Click OK.
  8. Add another mileage field, Urban, to the report using the same Urban Type layer. This time, add the clause that URBANTYPE does not equal to Rural.

    Adding a formula to calculate mileage
  11. Write the formula !Number Travel Lanes.LENGTH!*!Number Travel Lanes.NUMBEROFTRAVELLANES!.

    In this formula for calculating lane mileage, the following information is true:

    • !Number Travel Lanes.LENGTH! = !to_measure!-!from_measure! for the Number Travel Lanes event layer. The variable !LENGTH! is provided for every mileage layer. !LENGTH! is the distance value available to each layer being used to report mileage against.
    • The variable !Number Travel Lanes.NUMBEROFTRAVELLANES! comes from the values present in the attribute field of the selected mileage layer.
    • The event names are prefixed to the variables.
    • You can use formulas for calculating mileages such as VMT (Vehicle Miles Traveled, which is calculated by multiplying AADT by Length).

  12. Add another mileage field from the Toll Road layer and name it Toll Roads.
  13. Add two clauses in the attribute filter so that the mileage can be calculated on roads that have tolls on one side or both sides.
    Adding an attribute filter to the Toll Road layer

    Four mileage fields have been added.

    Four mileage fields are added
  14. Click Next.

    The Report Fields page appears.

    You can now format, run, and save the report.

Calculating mileages for dominant routes only

The Roadway Reporter allows you to calculate mileages only for dominant routes where route concurrences exist.

Concurrent routes are the routes which share the same pavement partially or fully but have different Route IDs of Route names. In the locations where these concurrences exist, you can choose a route that is considered dominant using a set of rules. For more information on setting up route dominance, see Configuring route dominance. Take, for example, the routes in this graphic:

Concurrent routes.
In Section1, Route2 and Route3 share a portion of the pavement and in Section2, Route1, Route2, and Route3 share a portion of the pavement. As per the route dominance rules, Route1 is the most dominant route followed by Route2 and Route3 respectively. The following table shows the mileages for each route:

Route IDMileageDominant SectionDominant Section MileageReported Mileage

Route1

3

Section2

1

3

Route2

4

Section1

1

3

Route3

3

1

Total

10

7

Therefore, if the route dominance rules are not taken into account, the double mileages are calculated for Section1 (Route2 and Route3) and triple mileages are calculated for Section2 (Route1, Route2, and Route3), and the total mileage for the three routes sums to 10 miles. Whereas, using the route dominance rules, mileages are calculated only once for each section and the total mileage for the three routes sums to 7 miles.

Note:
  • Route dominance rules should be configured to access this functionality.
  • In the case where the tool is unable to determine the dominant route either due to a tie or missing data, then one of the concurrent routes is chosen at random to calculate the mileage.

You can calculate mileages only for dominant routes by checking the Only calculate mileage on dominant routes option.

Calculating mileages for dominant routes
You can use this functionally at a more granular level by choosing to calculate mileages only for dominant routes on per mileage field basis:
Calculating mileages for dominant routes per mileage field.

Note:

Running a report on a route with a measure gap may produce the incorrect mileage if the mileage report was run on only a network with no events.

A workaround is to add an event layer to your report as a mileage field and uncheck the box next to this event field in the report fields screen so that the field does not display in the report.
