Transportation and Safety/Health


联合国可持续发展目标(2015-2030)中提到,建设包容、安全、有风险抵御能力和可持续的城市及人类住区。目前和城市交通密切相关的道路拥堵、安全预防等问题受到越来越多的社会关注。滴滴一直致力于用科技赋能公共出行安全领域,并在“人、车、路”三个维度进行了有效尝试。
“人”即驾驶员信息,包括IMU信息、轨迹信息、超速、疲劳等;“路”包括道路基础设施,车道线等;“车”即车龄、车型、车胎等。滴滴应用大数据、AI技术挖掘交通事故常发生的地点,识别多种不良驾驶行为,如:行驶速度过快、通行路口不减速等,并通过机器学习、数据挖掘等方法建立人、道路、路口等的安全画像,进而对司机播报预警,提醒司机注意驾驶安全,降低有可能导致的交通事故风险。


司机关怀助手智能机器人:基于知识库构建(网络爬虫、数据清洗、信息抽取、实体识别和关系抽取等),知识问答(实体识别、谓词识别、SP/OP问题分类等),医疗多轮项目架构(自然语言理解-NLU、对话状态追踪-DST、系统动作决策、循环神经网络-RNN模块)等关键AI技术能力,从网约车司机日常工作生活的真实需求出发,为司机群体量身定制一款智能化产品方案。通过情绪疏解、健康咨询、加油站查询,违章高发地提示、恶劣天气提示以及定制化的生日祝福等功能,在司机关怀的基础上,提升了司机群体的职业认同感及荣誉感。 结合AI for Social Good核心理念,希望运用有温度的技术,让网约车司机成为一份受人尊敬的职业。
