### 2.1 拥堵 ### 2.1 拥堵
拥堵指标计算分为东西方向和南北方向 拥堵指标计算分为协调方向方向和非协调方向
- 东西方向拥堵指数计算会针对每个路口的进口路段进行计算，统计每个路段的拥堵指数，并根据拥堵指数进行阈值判断后，获取该路段的交通状态 - 协调方向拥堵指数计算会针对每个路口的进口路段进行计算，统计每个路段的拥堵指数，并根据拥堵指数进行阈值判断后，获取该路段的交通状态
- 南北方向的拥堵指数计算是根据饱和度计算绿灯时间内，车辆空档时间。根据算法文档给出的计算公式进行相关计算后，判断其阈值范围，从而获取该路段的交通状态 - 非协调方向的拥堵指数计算：根据绿灯时间内车辆空档时间，计算饱和度。根据算法文档阈值判断拥堵等级。
### 2.2 失衡 ### 2.2 失衡
- 根据算法指标计算文档给出的计算公式，计算每个路口是否处于失衡状态 - 根据算法指标计算文档给出的计算公式，计算每个路口是否处于失衡状态
