How to show the nearest drivers to the point of departure?

Question

Java

Need help from experts. There is a taxi application, in it, when choosing a point of departure and delivery, it shows a fragment with a list of drivers, according to logic and meaning, it should show the drivers who are closest to the client, say, in some range. And in this case, it shows everyone by the date of registration. Can anyone help with this issue?

Method in the forehead.
Request through geomap the primitives of the car within a radius of 1,2,3,4,5 and so on kilometers.
Then, using api yandex map, select the length of the route for each car.
Then look at their employment. Suppose a busy car 5 km away is more profitable than a free car 20 km away if it is quickly released.
