The Posted Speed report is available in the US and Canada. It is used to ensure vehicles and drivers are not exceeding the posted speed limits. Where speeds differ, the Posted Speed refers automotive speeds or truck speeds as applicable. It doesn’t take into consideration variable zones, school zones, or non-white or caution signs such as yellow curve MPH signs. Only white signs are used.
A benefit of this report is it gives you precise graphical and numerical analysis over overall driver behavior over time.
The Posted Speed report allows administrators and dispatchers to analyze an operator’s speed over the course of a trip as it relates to the posted speed limit. In this report, a trip runs from a key-on event to a key-off event. HERE© provides posted speeds used in this report to Zonar. Updates are made quarterly. If a posted speed is incorrect or obsolete, see the article How to Report Posted Speed Corrections.
The Posted Speed database was last updated on August 1st, 2024.
Certain roads may not be included in the report results. This may be due to the classification level of the roads. Only arterial roads as defined by the FWHA are included in the posted speed report; non-arterials such as residential roads are not included.
If you have recently added this report to your Ground Traffic Control account, only data moving forward are shown in this report. Data for trips prior to the installation of this report are not shown. Similarly, data is compared to the available posted speed at the time it enters Zonar's database. If the posted speed is updated later, the report will not re-evaluate historical data.
Truck speed limits were made available on July 26, 2016. Running a report prior to this date will utilize the automotive speed when comparing speeding events. This is especially important to pay close attention to when using this tool for training or disciplinary action.
To access the Posted Speed report, from the main menu click Reports, then go to GPS Track & Trace and click Posted Speed.
Filters
Select from the following filters to display only certain Posted Speed events:
| Asset No | Select a single asset to return, or all assets. |
| Driver | Select a single driver, or all drivers. |
| Attribute Filters | Select an Attribute Filter (optional). |
| Select Attributes | Select an Attribute (optional). |
| Speed Classification | Select a single speed classification, or all. |
| Location Filter | Select a single location, or all. |
| MPH Over Speed Limit | Configure a threshold to display in the report. In the example, only Posted Speed events greater than 5 MPH are shown in the results. |
| Show Time Over Speed Limit | Configure a time threshold that an asset must exceed before being reported on the generated report. |
| Date Range | By default, Posted Speed events for Today are shown. Choose from Today, Yesterday, Last 7 Days or Last 30 Days. You can also select a custom date range of up to one month at any time. |
Summary View
By default, the Summary view is displayed, which shows a list of speeding events according to the filters set prior to selecting Apply. Each driver’s events are summarized and combined into one list item per day for the selected date range. The Details view shows a list of each Posted Speed violation based on the filters set, and it also displays the trip on the map in which the violation occurred. The Details view also includes a map showing the location of each occurrence and path of the driver over a selected time frame.
In this report, a Trip is from a key-on event to a key-off event.
| Speed Classification | Each asset must have a speed classification assigned to it. To do this, edit the asset details in Admin → Assets → Manage. By default, assets will be set to Undefined which will use the automotive speed limit when calculating speeding events. Assets created prior to July 26, 2016 will be labeled as Undefined and should be updated.
For more information on setting the classification, visit the Assets topic. |
| Driver | If specific hardware is installed in the asset that the driver must log into prior to the trip, their name will be listed. If such a device is not installed, the driver is listed as Unknown. |
| Total Time Driven | This column summarizes the total drive time for each asset based on the search filters and date range. |
| Total Time Speeding | This column summarizes all speeding events’ duration during the specified date range. |
| Speeding Percentage | This column is the percentage of total time speeding in relation to the total time driven. |
| Max Over | This column lists the maximum speed over the posted speed limit that the asset traveled during the date range. |
| Count | This column is a tally of how many times the asset went over the posted speed limit. The asset going over the posted speed limit and back down below the speed limit is considered one event. |
Details View
Click Details at the top of the results window to switch to the Details view. Details view shows a list of assets that match the search filters, including a map, which displays the path for each asset and a Posted Speed Graph further detailing the path the asset took. Click the labels at the far right of the details view to view the List & Map, List Only, or Map Only.
List & Map (default)
List Only
| Asset No. | Asset ID. |
| Speed Classification | The asset’s current speed classification, which can be changed in Admin → Assets → Manage. For more information on setting the classification visit the Assets help topic. |
| Driver | Displays the name of the driver for the generated report. |
| Event Start | This shows the moment when the asset went above the posted speed limit. |
| Event End | This shows the moment when the asset went back below the posted speed limit. |
| Time | The duration of the event. |
| Limit | The current posted speed limit for that area. |
| Max | The maximum speed the asset traveled during the speeding event. |
| Max Over | The maximum MPH the asset traveled over the posted speed. |
| Lat/Long | The location where the speed event was recorded. |
Map Only
| Map | The map shows the trip in which the speeding event occurred, which was selected while the list was visible. The path of the trip is indicated by: Green: Under the speed limit. Red: Over the speed limit. |
| Posted Speed Graph | The graph shows the entire trip and includes the speed of the asset throughout the trip. The posted speed is shown as blue lines on the graph. |
| Zoom | The graph can be further analyzed by zooming in on the trip. Use the four presets for a quick zoom. The presets zoom into the area around the selected speeding event. |
| Graph Detail | The graph shows three pieces of information. Asset Speed during the trip, the speed Limit along the trip, and the Over speed limit portions of the trip. Clicking one of these pieces of data disables it from displaying in the graph. Clicking the data again enables it in the graph. |
Trip Navigation
While you can zoom in on the graph detail, this slider shown allows quick navigation along the entire trip. You can also drag the sliders to zoom in and out manually.
Dragging the left slider to the right or the right slider to the left decreases the amount of the trip displayed in the graph.
Map Icons
The triangle indicates the location as it relates to your selection along the graph as well as the direction of travel. This example shows the asset traveling west.
The circled M indicates where the maximum speeding event occurred.
Graph Data
The graph contains several pieces of data, including speed of the asset, posted speed limits, and maximum speeding event (when the asset was the most over the posted speed limit). Hovering over the speed line gives you additional information and adjusts the location icon on the map.
