Street intersection density is a useful measure of network connectivity. This tutorial will show how to calculate street intersection density using QGIS. The analysis of calculating street intersection density is commonly used in transportation design, to scope out the best walkability of neighbourhoods and bike paths. This tutorial aims to demonstrate how to use spatial analysis in understanding spatial patterns for urban accessibility while also learning how to use an open-source GIS software available for anyone. In the end, creating a map showing intersection density across a city. This is useful for people in urban planning and land use planning. |

Purpose
Street intersection density is a useful measure of network connectivity. This tutorial will show how to calculate street intersection density using QGIS. The analysis of calculating street intersection density is commonly used in transportation design, to scope out the best walkability of neighbourhoods and bike paths. This tutorial aims to demonstrate how to use spatial analysis in understanding spatial patterns for urban accessibility while also learning how to use an open-source GIS software available for anyone. In the end, creating a map showing intersection density across a city. This is useful for people in urban planning and land use planning.
For example, this tutorial will be calculating the street intersection density of the city of Ottawa.
About QGIS
QGIS (Quantum GIS) is a free and open-source GIS program released under the GNU General Public License. It has a wide variety of features that facilitate the display, analysis, and publishing of spatial data (QGIS, n.d.). In the context of this tutorial, vector data editing and creating grids will be demonstrated. QGIS is available for download on a variety of operating systems from Windows, Mac, Linux, BSD and mobile devices.
Note
The QGIS version used here in this tutorial is 3.14 on a Windows operating system. When trying this tutorial, if you are using a previous or updated version of QGIS or on a different operating system, please keep in mind there may be differences in the figures and instructions used in this tutorial.
