Oh, thank you.

Let's take them one at a time:

area of the car, This is very important. I live in a desert area, which is very hot. That means a higher heat load than if the car is in a cold area. So, hot area=high heat load. Cold area= lower heat load. You'll need to define the area of the car.

- Sunlight This is more important in the daytime than at night. It is also somewhat dependent on the area of the car, as described above. Daytime=higher heat load. Night time= lower heat load.

- Engine heat This is also related to area, but not so much. You will need to define the state of the engine. On, or off. On=more heat. Off= less heat.

- Road heat Not important. Only affects the bottom of the car. Bottom=hotter. Top= cooler. Averages out from top to bottom.

- Transmission Heat goes to radiator, if car is so equipped. But you don't list radiator as a potential heat source, so not included in calculations.

- Exhaust heat This is of no concern to you, and would only affect people who are too close in the first place and should BACK OFF anyway. Close= hotter. Far away=cooler.

I would consider much more if I were the student, but I'm just an old man and have read the FAQ'S of this site. Especially the part about homework.
