Math SL AI Internal assignment

I already wrote down my Introduction, background research, and methodology, and my aim for my exploration but it needs work. I do not think that my exploration is attainable and will get me a good mark for my IA so if it’s possible you can tweak it a bit if needed but you might not need too.

The rubric is displayed below in what I need to complete. 
If the IA exploration is Unatainable, it is fine if you can change the topic a bit since now it is  

Exploring the Probability of getting into a car accident within (5.4km) and how does it affect Traffic Flow
