Impact allows you to build mobility network scenarios, analyze and compare them without the technical complexity of a full-blown traffic model.
This is done in three following steps:
Edit the network to represent a scenario.
Analyze and compare the impact of different scenarios.
Communicate scenarios and/or results with project partners, the public, etc. interactively and stylishly.
If you want an Impact for your city or study, get in touch, we're happy to help!
Impact consists of two components:
Provides you with the necessary tools to customize the existing road network and subsequently calculate routes based on the customized netwrok by-means-of a built-in route planner. These tools allow you to customize anything on the network including but not limited to: changing existing roads, remove roads or add new ones, edit bicycle lanes, add pedestrian crossings, change vehicle restrictions, modify one-way restrictions, road closures, etc.
To start editing, first zoom-in to the area where you want to edit the network and then click on the edit menu.
Once clicked on the edit menu, the map switches to the Edit-mode in the exact same area.
If on the previous page and before clicking on the edit menu you have not zoomed-in enough on the edit area, editable map will also open in a zoomed-out level and you will see no link to edit. However, as soon as you zoom to the edit area, the links start appearing for you to edit. Below, you can find two examples on how editing the netwrok is done.
Once the network is edited as per the scenario in hand (e.g., Road Constructions/works), you can start experimenting with the changes that this scenario will bring about by switching to the Test-mode. Test-mode is an interactive map featuring a route planner that can be also shared online.
Test-mode allows you to verify accessibility as well as possible routing changes for an Origin and Destination pair. This verification is simply done by 2 mouse clicks on the map where:
Subsequently, you can select your desired routing profile/s in the "ROUTING" box at the top-left corner of the map.
Depending on your Impact subscription, a number of instances will be at your disposal to create scenarios. It is recommended to keep instance "0” as the Base-Scenario representing the existing situation and edit the network in other instances as per your scenarios (e.g., future plans, etc.). This allows for an objective comparison between the existing situation and created scenarios as well as in between scenarios. See below for an example:
Below you can find an example of this interactive map in which we've added a set of road closures to the network. In addition to the routing changes, you'll also notice a change in the color of some links (white -> red or vice versa) upon changing the routing profile (mode of transport). This color change reflects the changes in the accessibility (red = inaccessible) caused by these road closures.
A QGIS plugin with a set of network analysis tools using origin and destination data with which you can study the different variants and transport modes of the network.
The plugin allows you to:
There are currently two versions of the Impact Toolbox available. The first is the online version that can be found in the QGIS repository. The second and more comprehensive version is the local version that is available to all our clients to be installed manually. These two versions will be eventually merged as one online version that can be installed via the QGIS repository. Therefore, we continue with describing the existing (we're constantly working to add more) functionalities of the comprehensive version.
The toolbox is currently consisting of four widgets.

Either using our Open Data API or your local Origin-Destination database, the results of your network analysis will be as elegant as shown below:
If you're thinking that Impact sounds too good to be true, why don't you give it a try for free? 😉
 Our Open Data API currently features the data from “FOD Mobiliteit Enquête woonwerkverkeer 2017”. More open data will be available soon.
 Calculated routings are including a frequency of use and an aggregate traffic count for each road segment.
[3,4] Calculated routings are including a frequency of use and an aggregate traffic count (provided that your local database has travelers’ counts for each OD pairs) for each road segment.
