How do taxi services take into account the peculiarities of cities?

Question

PHP

I do a taxi service. I look at other services and see that they have different tariffs in different cities. But it can still be stored normally in the database. Create a rates table with city_id, per_km, per_min, min columns. But for example, Yandex has some additional fields in different cities. From the metro this is more expensive, etc. How do they implement all this? I think in packs of shit code (a lot of if) or how can I do it more beautifully?

Answer 1

Of course, everything is decided in Ya.Taxi

packs of shit code

, do not doubt

Answer 2

Regional split. The table will be simple.
Determining in which area of ​​​​the city the address is not at all difficult.
