Bus Schedule Database Design

Question

I am trying to create a db to store schedules for 300 different bus routes. Each route has a different number of stops and different times on Monday-Friday, Saturday and Sunday. I presented the bus departure time for each route as follows: I am not sure if I should have zero values ​​in the table, does this look normal?

route,Num,Day,    t1,   t2,   t3,    t4    t5      t6      t7      t8     t9    t10 

117, 1, Monday,   9:00, 9:30, 10:50, 12:00, 14:00  18:00   19:00   null   null   null
117, 2, Monday,   9:03, 9:33, 10:53, 12:03, 14:03  18:03   19:03   null   null   null

Answer 1

No, that doesn't look good. Each route / day / stop time value should be on a separate line:

 Route, Day, Run #, Stop #, Time

 117, Monday, 1, 1, 9:00
 117, Monday, 1, 2, 9:30
 117, Monday, 1, 3, 10:50
 117, Monday, 1, 4, 12:00
 . . . Finish Run #1 . . .
 117, Monday, 2, 1, 9:03
 117, Monday, 2, 2, 9:33
 117, Monday, 2, 3, 10:53
 117, Monday, 2, 4, 12:03

and etc.

Route, Day, Run # RunID, Route, Day Run # StopTimes .

, (Time1, Time2 Phone1, Phone2), , .
