The Work Zone Performance Report empowers you to quickly generate a performance report for any work zone. Your report tracks congestion, speed, and delay against your defined goals for a period of up to seven days. You can initiate a Work Zone Performance Report from any RITIS tool that includes work zone event data or directly from the PDA main menu.
Key features include:
- Configurable performance goals for congestion, speed, and delay.
- Work zone analysis for upstream and downstream segments.
- Weather and traffic incident data for assessing influence on work zone performance.
- A dynamic three-to-seven-page PDF ready for export and distribution.

How to Initiate a Work Zone Performance Report
There are three methods for initiating a report:
- You can select the report option where work zone event data is present in any RITIS tool. This option imports the work zone location to the query page. This method is recommended (see example below).
- You can access the Work Zone Performance Report directly from the PDA main menu.
- You can access the Work Zone Performance Report through the Report Templates page.
Overview of the Query Form
The query form is like other PDA tools where the workflow consists of steps to build a query, and the segment selections will be plotted and edited in the map box.
NOTE:
If you initiate a report from a work zone's details identified in another RITIS tool, the road information will automatically populate based on that work zone's location.
If you start a report directly within the Work Zone Performance Report, you will need to complete the query form manually, as outlined below.
| 1 | Select a country |
| 2 |
Select segment type and data source The segment type and data source specify the provider and segmentation type used to calculate performance measures.
Note: The provider and segmentation type selections will persist from your previous use of the Work Zone Performance Report. |
| 3 |
Select work zone location The work zone location establishes the spatial parameter of your report and will be comprised of one or more contiguous segments in a single direction. The work zone selection process is similar to the road selection process in other PDA tools. For more information on the road selection process in Work Zone Performance Report, please see: Work Zone Performance Report - Road Selection. Note: If you initiate a Work Zone Performance Report from work zone details in another tool, the road location will be automatically populated for you. You will see the location represented on the map and the work zone description under this step in the query form. The work zone location on the map will have an arrow indicating direction. |
| 4 |
Select additional segments around the work zone's location You can add upstream and downstream segments to enhance your reporting on the impact of the work zone. Note: The additional segment selection process is the same as the road selection process in other PDA tools. For more information on the road selection process in Work Zone Performance Report, please see: Work Zone Performance Report - Road Selection. Once you have selected upstream or downstream segments, they appear in the map box with an arrow indicating direction in a color differentiating the selection from the work zone segments. Since the results are only useful if the work zone segments and adjacent segments are well ordered, you should remember the following: You can select upstream and downstream segments as a single selection that overlaps the work zone or you can make two discrete selections of additional segments.
|
| 5 |
Select date range The work zone performance report will generate metrics for a date range of up to 7 days allowing for weekly reports. To select an analysis date range:
|
| 6 |
Select days of week You can toggle on and off days of the week. This selection process allows you to query only weekdays or exclude days when the work zone is not in operation. |
| 7 |
Select hours of operation To accurately report on work zone performance, you will want to provide the hours of operation. You may select up to three periods with the slider. The following examples provide best practices for time selection.
|
| 8 |
Compare against another time period (optional) In addition to reporting performance measures for your selected date range, you may add a comparison time period to your report to enhance your understanding of the impact of the work zone. This is an optional step that will produce line chart comparisons focused on speed, congestion and weather metrics. To enable a comparison period:
|
| 9 | Provide a title for this report (optional) |
| 10 | Provide notes for this report (optional) |
| 11 |
Select Submit The Submit button will be available when all required parameters are complete. When you select Submit, a new tab will open with your Report. |
