As a user, I want an autonomous car to map roads. The car can drive itself up to 200km after refueling. The car should reach a fuel station and refuel itself before it runs out of petrol. Car always starts from a garage outside of the area with full fuel and returns to the garage once the mapping task is complete.
I want to run a command “php map.php --road_type=urban --road_length=900” and I want to see the below output after the mapping task is completed.
- total time spent on the mapping task
- number of times refuelled
- total distance travelled
- --road_type accepts urban or rural
- On urban roads, the maximum range of the car drops by 25% due to traffic
- The garage is 20km from urban areas and 50km from rural areas
- From any point, the car can refuel itself by taking a detour that is a round-trip of 10km.
- Time to refuel is 30 mins. There are no fuel pumps between the city and the garage.
- Speed limit imposed by the police is 70kmph. Urban traffic causes a 25% decrease in the limit. Rural areas allow a relaxation of 15% on the limit.
- The car must travel the entire length of the road and return to the garage to mark the mapping task as complete.
- While a web UI is not expected, the interface on the terminal should have good user experience
