LOCATION: Belgium, Ghent
TARGET AUDIENCE: public
CHALLENGE
Ghent is one of the major cities of Flanders and is home to 265,000 inhabitants. In spring 2022, a new bicycle tunnel was constructed near the city centre. The impact of the planned works on traffic was fairly large and well researched.
With DUET, we want to test the effects of the closure of the bridge and the adjacent first road segment of the Nieuwewandeling street.
APPROACH
By using the DUET solution, we investigate three scenarios:
- bridge closure in the direction towards the city center (scenario A),
- bridge closure in the direction away from the city center (scenario B),
- bridge closure in both directions (scenario C).
For each simulation, a delta map is created showing increase and decrease of traffic volumes in an intuitive way.
EXPECTED OUTCOME
Since this bridge is heavily used (over 1000 motorised vehicles during rush hour for both directions together), the closure may have a high impact on traffic.
Explore this case by scrolling down to the scenarios. Three scenarios are available, scenarios A, B and C.
Read the background information and click the “Learn more” button to see the scenario on a map.
You can also directly switch between scenarios by selecting the scenario you want to explore in the pop-up window.
For the three scenarios, you see a delta map indicating what road segments are closed (red signboards), with a specific colour code :
After exploring the scenarios, you can vote on the scenario you like most. The poll is added below the scenarios. Vote and immediately see the voting results of all voters that participated.
For this Flanders case, we used :
- Digital Terrain Model Flanders
- Gent 3D Buildings Level of Detail 2 (detailed building contours)
- Gent road network
For this Flanders case, we used :
- Integrated Flanders and Ghent Traffic model
- KULeuven traffic model calculation algorithms
