秀洲区兴新路-兴园路段道路积尘负荷数据

道路积尘负荷是量化评估道路扬尘污染程度的核心指标。
精准治污：识别高积尘路段，指导环卫部门优化洒水、清扫频次，降低扬尘对空气质量的影响；
交通规划：为城市道路改造、重载车辆限行政策提供数据支撑，减少二次扬尘污染；
环境评估：动态监测施工区域、工业园区的道路污染扩散趋势，辅助环境督查与治理效果评价；
公众服务：预警高污染路段，提升居民出行健康保障。通过“数据驱动”助力智慧环保，实现从被动治理到源头防控的升级。道路积尘负荷是表征单位面积路面上具有道路扬尘污染潜势的道路尘土质量的指标，通过以下步骤得出：
1、数据收集：通过车载移动监测设备（车顶、车尾）进行合法收集数据，并进行脱敏、降噪、清洗、聚集、分析。
2、数据加工：移动监测设备直接采集车顶与近地面车尾PM2.5、PM 10浓度数据，根据车顶车尾差值并结合积尘负荷常数来计算输出道路积尘负荷字段。其中积尘负荷常数通过人工收集地面积尘负荷数据与移动监测数据皮尔逊相关性测试得到，为固定常数值，与监测车重量、车载移动监测系统安装等因素有关。数据结构中的状态字段N即Norml，表示收集状态正常。
道路积尘负荷数据值越大，表示道路积尘情况越严重。

Road dust load is a core indicator for quantitatively assessing the degree of road dust pollution.
Precise pollution control: Identify high dust load road sections to guide sanitation departments to optimize the frequency of sprinkler and sweeping operations, thereby reducing the impact of road dust on air quality;
Transportation planning: Provide data support for urban road reconstruction and heavy vehicle restriction policies, so as to reduce secondary dust pollution;
Environmental assessment: Dynamically monitor the road pollution diffusion trend in construction areas and industrial parks, to assist environmental supervision and governance effect evaluation;
Public services: Issue early warnings for high-pollution road sections, to improve residents' health protection during travel. By leveraging "data-driven" smart environmental protection, we can realize the upgrade from passive governance to source prevention and control.
Road dust load is an indicator that characterizes the mass of road dust with potential to cause road dust pollution per unit area of the road surface, which is calculated through the following steps:
1. Data collection: Legally collect data via in-vehicle mobile monitoring equipment (installed on the roof and rear of the vehicle), followed by data desensitization, noise reduction, cleaning, aggregation and analysis.
2. Data processing: The mobile monitoring equipment directly collects PM2.5 and PM10 concentration data from the roof and near-ground rear of the vehicle. The road dust load field is calculated and output based on the difference between roof and rear data combined with the dust load constant. The dust load constant is a fixed value obtained through Pearson correlation test between manually collected ground dust load data and mobile monitoring data, and is related to factors such as the weight of the monitoring vehicle and the installation of the on-board mobile monitoring system. The status field 'N' in the data structure indicates Normal, meaning the collection status is normal.
A larger value of road dust load indicates a more severe road dust accumulation situation.
