Problem Statement
The application allows users to share rides on a route.
- Users can either offer a shared ride (Driver) or consume a shared ride (Passenger).
- Users can search and select one from multiple available rides on a route with the same source and destination.
Usecases:
Application should allow to register users:
create_user(name:"John",gender:M,age:26)
Users should be able to add vehicle (a user can have multiple vehicles):
create_vehicle(name:"John", vehicle:"swift", regNo:"KA-09-32321")
Users should be able offer rides: offer_ride(name: "John", vehicle: "swift", seats_available: 3, origin: Bangalore, destination: Mysore, start: 'March 21, 2024, 10 AM', duration: 3h)
Users should be able to select rides based on origin, destination, and selection preference. select_ride(name:"smith",origin:bangalore,destination:mysore,seats_requierd:2,earliest_ending_ride)
Users can have preferences like:
- Earliest ending ride or lowest duration ride
- Preferred Vehicle (Activa/Polo/XUV)
- Most Vacant.
Users should be able to get all the rides offered and taken by the user.
