行业痛点再审视

动态需求与静态能力的鸿沟

在城市化进程加速的背景下,道路交通需求呈现高度动态化特征:早晚高峰潮汐流、节假日出行波动、突发性拥堵事件等,均对信号控制方案提出实时适配要求。然而,传统交通信号优化模式长期受限于三大瓶颈:

数据感知与决策割裂

依赖人工经验与短周期交通流调查(如早晚高峰2小时流量统计),导致方案设计滞后于真实需求。

模型适配能力有限

传统控制理论对突发拥堵、潮汐车流等场景响应滞后,缺乏动态自适应性,难以精准刻画路口级人车非混行特征。

优化闭环未成形

方案调整依赖人工经验试错,缺乏持续量化评估与迭代机制,导致60%以上城市路口年均信号方案更新频次不足2次,而实际需求变化周期普遍小于1个月。

DeepSeek技术定位

宏观赋能与中观突破

基于大模型的核心优势,DeepSeek聚焦“动态诊断-科学决策-持续进化”三大能力建设,在现有技术边界内实现价值最大化:

宏观路网:需求预测与策略生成

中观调控:数据驱动的动态适配

持续进化:闭环迭代新范式

范式变革

构建闭环驱动的治理新模式

易华录凭借在交通行业多年的缓堵优化经验及在交通数据治理方面的专业技能,构建了缓堵优化智能体。该智能体融合DeepSeek深度思考推理能力与易华录专业的信控知识库,能够对现有配时方案进行详细问题分析、优化策略呈现,输出优化后的配时方案,并对方案运行效果预测。这一创新解决方案旨在推动城市交通控制迈上新台阶,使信控配时方案能够更好地满足城市交通出行需求。

01

智能诊断,一键优化

缓堵优化智能体,基于路口渠化、现状配时方案及交通流数据,利用深度强化学习和信控优化算法,借助DeepSeek大模型智能处理能力,从车流量、方案相位设计等方面进行精确问题分析,提出针对性优化策略,并生成科学配时方案。当前,缓堵优化智能体已集成至易华录自学习优化控制系统,通过API接口为系统提供服务。

智能体入口优化

展示原有方案信息

智能体分析结果反馈

02

数据驱动,效果量化评估

缓堵优化智能体整合多维度数据进行对比分析,直观展示优化前后方案的差异,包括相位相序、配时参数、排队长度以及平均延误等关键指标。依托大量实时和历史数据,智能体还能对新方案进行精准分析与效果预测,使通行能力的提升及排队长度的改善一目了然。

用户价值

可感知的渐进式提升

对于交警用户,DeepSeek带来的不仅是技术工具升级,更是治理能力的质变:

精准化:实时发现路口级瓶颈问题,避免“一刀切”式优化;

敏捷化:方案迭代周期从“季度级”压缩至“周级”,响应速度提升5倍;

可持续化:建立交通治理数字资产库,推动城市缓堵进入“持续自优化”新阶段。

作为服务全国300余座城市的智能交通企业,易华录以DeepSeek技术为核心,构建了“数据发现问题-模型生成建议-人工决策优化-系统验证效果”的闭环治理体系,通过增强人类决策能力,让交通工程师从繁复的数据清洗中解放,聚焦于核心价值创造。未来,随着感知技术与控制理论的突破,这一系统将持续进化——但今天的每一步扎实实践,都在为城市交通的“可知、可测、可控”奠定基石。
