智慧交通车流量监控项目

数据来源

monitor_flow_action 监控数据表

data 日期
monitor_id 卡扣号
camera_id 摄像头编号
car 车牌
action_time 某个摄像头拍摄时间 s
speed 通过卡扣的速度
road_id 道路id
area_id 区域id

monitor_camera_info 卡扣与摄像头基本关系表

monitor_id 卡扣编号
camera_id 摄像头编号

需求说明

  1. 卡扣监控

    全部使用SparkCore实现

    • 筛选条件内的卡扣信息

      根据使用者传入的指定条件,筛选出指定的一批卡扣信息

    • 检测卡扣状态

      基于第一步查询出来的卡扣信息结果来实现

      检查卡扣(monitor_id)状态,卡扣状态分为正常,异常状态。

      摄像头(camera_id)的状态分为正常,异常。

      异常摄像头的所有信息(monitor_id: camera_id)

  2. 通过车辆数最多的Top N卡扣

  3. 统计Top N 卡扣下经过的所有车辆详细信息

  4. 车辆通过速度相对比较快的Top N卡扣

      车速:
    	120=<speed 		高速
    	90<=speed<120	中速
    	60<=speed<90	正常
    	0<speed<60		低速
    
  5. 卡扣 ‘‘0001’’下所有的车辆轨迹

    • 过滤日期范围内 卡扣“0001”下有那些车辆
    • 过滤日期范围内 这些车辆经过卡扣的时间,按照时间升序排序
  6. 车辆碰撞

  7. 随机抽取车辆

  8. 卡扣流量转换率

  9. 实时道路拥堵情况

  10. 动态改变广播变量

  11. 统计每个区域中车辆最多的前3道路
