question introduction

A car manufacturer includes an event data recorder in their cars. This device begins recording when the car’s sensors detect a sudden change in speed. The data captured can be analysed when required. A sample of data is shown below.

Event dataSample

-----------------+------------

speed (mph) 58.2

accelerator (%) 42

brake (%) 0

seatbelt on True

When triggered by a sensor this data is sampled 10 times per second for 20 seconds.

Software is to be developed that can analyse the data captured from a car’s event data recorder.

⁠

part a

During the analysis stage boundaries are identified.

State two boundaries for this task.

answer part 2

⁠

part b (i)

Use a programming language of your choice to define a suitable record (class) data structure for the data shown above.

(edit the reading.java file in the project)

⁠

part b (ii)

Use a programming language of your choice to define a variable that can store the details of 200 readings. Use the record (class) data structure you made in part (i)

(edit the carData.java file in the project)

⁠

additional part

Create a method to read or import the values from the readings.csv file.

(edit the carData.java file in the project)

⁠

part c

Create a method to find the maximum speed (and display it)

(edit the carData.java file in the project)
