AI总结:

本研究提出整合MOVES与多类开源数据的链路级交通排放估算框架,用神经网络预测运行模式分布,在波士顿大都会区实验中较基线将关键污染物排放估算RMSE降低超50%,验证了全开源数据低成本可复现排放估算的可行性。

摘要:

开源数据为估算城市区域的车辆活动与排放提供了可扩展且透明的基础。本研究提出了一个数据驱动框架,整合MOVES(机动车排放模拟器)与开源GPS轨迹数据、OpenStreetMap(OSM,开放街道地图)道路网络、区域交通数据集以及卫星影像提取的特征向量,用以估算链路级运行模式分布与交通排放。我们训练了一个神经网络模型,仅利用易获取数据衍生的特征来预测MOVES定义的运行模式分布。\n该方法采用波士顿大都会区45个自治市的相关开源数据开展应用研究,基于OSM开源GPS轨迹构建了“真值”运行模式分布。与MOVES基线相比,所提模型在CO、NOx、CO2和PM2.5等关键污染物的区域尺度交通排放估算中,将RMSE降低了50%以上。本研究证明了利用完全开源数据源实现低成本、可复现的数据驱动排放估算的可行性。

英文摘要:

Open-source data offers a scalable and transparent foundation for estimating vehicle activity and emissions in urban regions. In this study, we propose a data-driven framework that integrates MOVES and open-source GPS trajectory data, OpenStreetMap (OSM) road networks, regional traffic datasets and satellite imagery-derived feature vectors to estimate the link level operating mode distribution and traffic emissions. A neural network model is trained to predict the distribution of MOVES-defined operating modes using only features derived from readily available data. The proposed methodology was applied using open-source data related to 45 municipalities in the Boston Metropolitan area. The "ground truth" operating mode distribution was established using OSM open-source GPS trajectories. Compared to the MOVES baseline, the proposed model reduces RMSE by over 50% for regional scale traffic emissions of key pollutants including CO, NOx, CO2, and PM2.5. This study demonstrates the feasibility of low-cost, replicable, and data-driven emissions estimation using fully open data sources.
