Hotel arrivals in Switzerland: POI layer and demand curve

This mod includes a POI layer and a demand curve showing the number of people arriving at Swiss hotels. The data is based on the official figures of the Federal Statistical Office (BFS) for the year 2023. This applies to the location of the POIs, the demand of the POIs and the distance distribution of the demand curve.

In total, the POI layer contains around 450 POIs with hotel demand throughout Switzerland.

The demand curve and the POI layer are intended to represent guests who start or end their vacation and thus generate tourist traffic. They are not intended for day trips to mountains, historic city centers, museums, etc.; separate POIs should be created for these individual destinations with relatively local demand.


Why is a POI layer for hotel arrivals in Switzerland useful?
Switzerland is a country that is heavily influenced by tourism, and this also has an impact on traffic. Many small mountain villages with a small population attract many tourists who stay overnight. These are either classic ski resorts or simply beautifully situated. But a layer with tourist flows also makes sense for Swiss cities, since tourists often travel significantly further than other travelers.

Why does the demand distribution by distance look so strange?
For each country of origin, a normal distribution of distances to the hotel was assumed based on the statistics. Since a relatively large number of people come from Switzerland itself or from neighboring countries, trips between 100 and 300 km are most common, but there is also an accumulation between 500 and 800 km. At 500 km, Nimby switches from a 20-km grid to a 100-km grid, which results in an apparent peak for the 500-600 km distance range.

Does the demand curve also apply to hotels in other countries
Of course not 1:1, since every tourist destination has a slightly different distribution of travelers and the distances between the individual countries also vary, but in principle the demand curve should be appropriate for towns in Western and Central Europe.

Is every hotel in Switzerland individually mapped?
No, the BFS compiles statistics by municipality, which served as a basis and the respective POI was set as a hotel location as much as possible. In large municipalities, several areas were created as needed and the demand for the number of hotels was divided approximately proportionally. Accordingly, individual mountain hotels, etc. are usually not shown.

Are all hotel arrivals covered?
Not quite. There are places with hotels that do not report enough overnight stays or arrivals each year to be recorded by the BFS. No POIs were created in these places (<1 arrival/day).

Are all countries of origin covered?
The demand curve covers all countries of origin that are reported separately by the FSO. It does not include destinations that the FSO summarizes due to low demand.

Why are POIs sometimes so unevenly distributed?
This is due to the political municipal boundaries, according to which the BFS maintains the statistics. In some cases, hotels are very close to each other geographically, but are located in different municipalities, which is why two POIs were created.

Why are some POI names strange or do not match the village in which they are located?
Where known and meaningful, the place name was used instead of the municipality name to name the POI, but in principle the municipality was used for naming according to the BFS.

How many passengers are generated?
In principle, the demand per POI was set to correspond approximately to the average daily hotel arrivals. However, since the demand curve shows high demand values for distances up to 12,000 km, the full number of passengers to the hotels in NIMBY can only be reached if a very large network (intercontinental) is available.


Can the demand curve be used without the POI layer?
Yes, simply activate Mod and deactivate the POI layer in the options under “Change POI layer options”.

Something seems strange or isn't working as desired?
Creating the mod involved a lot of data work, so it's quite possible that one or two errors have crept in. If something doesn't seem right, it would be nice if you could let me know so that I can fix it.
