C++ Is my code leaning towards becoming spaghetti like? Am I using to many switch statements. Is there something better practice to do? [closed]

I'm attempting to build a "simple" program based on the bus schedule in my area. It displays the 12 available bus stops. Then selecting your departure time and choosing the Ending destination point. What I would like to know before I try to implement the math of the code. Is what' I've written efficient or unnecessary lines of code?

#include <iostream>
using namespace std;

void BusTravelingDistance(){}; //function to do some math from distance in mile/km point a to b
void BusTravelingTime(){}; //function to do some math length of time traveled HH:MM

int main() //Downtown Hilo to Kaumana.
{
    int choice;
    int BusPickUpLocation[12];
    int BusDropOffLocation[11];
