Tackling congestion at the Karawanks tunnel through surveying
With long haul transport on the rise in the Alpine Karawanks area, the local government has decided to build a second tunnel next to the already existing one. Since Slovenia joined the Schengen area in 2007, congestion has often cropped up at the tunnel, particularly during weekends. To solve this issue, a contract has been signed to have a new tunnel completed by 2023. Given this, it is wise to first look at the properties of the original tunnel and see if anything can be learned or gleamed from its 14 years of operation. The best tool for this requires creating a model with a broad range of capabilities and with a capacity to model traffic flow among other things.
Complete tunnel survey in a single night
Before any real world phenomena can be modelled, it must brought into the office via surveying. Furthermore, all of this had to be done in such way that the already existing congestion problems are not exacerbated while doing so. Enter Geodézia’s mobile mapping system. Traditional surveying techniques would have had the tunnel shut down for weeks, inconveniencing motorists and increasing logistics firms costs significantly, an unpopular solution, by anyone’s estimate. Geodézia’s mobile mapping system handled the task of surveying the tunnel in a single night, with the tunnel closed in the least busy hours of the day.

Assess clearance profiles and model traffic information
The information gathered had a variety of uses. For one, the authorities could determine whether the clearance profile of the existing tunnel was wide enough for use by the long-haul trucks expected to pass through it. This way they could determine whether to build a new tunnel with a wider clearance profile or save costs by the virtue of knowing that the current tunnel’s clearance profile is sufficient.
Detect structural detorioration in the tunnel
Tunnel scanning itself has a variety of important applications such as detecting where the tunnel structure has experienced the most stress from naturally occurring ground movement. As you can see our tunnel surveying service empowers you with spatial information from start to finish. The surveyed information can inform key decisions from the get go, ensuring that your projects are completed on time and cost efficiently.
