4th Scenario for algorithm tweaks

Car approaches, its red, min timer has not expired/dosn't turn right away
when min does expire, the other lane has a lot of traffic,
when min timer expires it still does not change/need to shuffle cars through the intersection
need sensor to tell us the amount of traffic, sensor 'enters' car into arraylist or controller enters into array list

Sensor needs 2 sensors: far away sensor for traffic and a close sensor for less amount of cars.

both sensors generally are true and false: 1st true, second false = not much traffic, both true change light to green for longer time to get cars through light.

首先執行 Java 交通路口模擬，並找出現有的交通號誌計時器與感測器邏輯。將目前的行為與 issue 中描述的四個情境進行比較；完成標準應包括已定義的感測器輸入、車道交通處理，以及讓車輛通過路口的號誌變化。

由索引模型根據 Issue 內容生成。
