Transport models for air quality

19018
From 2019 to 2020
This project is a testcase to investigate if an alternative approach to generate transport volumes can deliver sufficient quality to feed air quality models, as compared to the current approach with Flanders' Promovia model. In the current approach, the road network is not frequently updated and changes in it are not considered (e.g., implementation of new circulation plans).

We tested the approach developed by TML in the ClairCity project, for quick scan estimates of traffic volumes. For this, we use a stepwise approach, building a network based on OpenStreetMap (OSM), estimate the traffic volumes, adding detail and complexity with each step, to understand what level of calibration is necessary in scope of application in air quality models.

We focus exclusively on estimating average daily traffic volumes, without the emission calculation itself. The selected testcase is a region centered around Ghent.
