Java Documentation

This documentation will help you implement your decision engine for an autonomous vehicle.

Fill in the decide method with a program that analyzes the given scenario and returns a Decision enum to indicate which group to save: Decision.PASSENGERS or Decision.PEDESTRIANS. See below for the data available in each scenario.

Scenario Information

Method	Returns	Type
getPassengers()	Array of people in the car	Person[]
getPedestrians()	Array of people who are near the car	Person[]
hasPedestriansInLane()	Whether or not the pedestrians are in the street	boolean
isLegalCrossing()	Whether or not the people are crossing legally	boolean
hasYouInCar()	Whether or not you are in the car	boolean

Accessing Person Objects

You can loop over all of the passengers (or pedestrians) like so:

Person[] passengers = scenario.getPassengers();
for (Person person : passengers) {
    String charType = person.getCharacterType();
    System.out.println(charType);
}

You can also select a specific person by their index:

Person[] pedestrians = scenario.getPedestrians();
if (pedestrians.length >= 1) {
    Person firstPed = pedestrians[0];
    String charType = firstPed.getCharacterType();
    System.out.println(charType);
}
