    // 路网状态缓存Key
    private static final String ROAD_STATUS_KEY = "traffic:road:status:";
    // 数据有效期（7天）
    private static final long DATA_EXPIRE_DAYS = 7;

    /**
     * 采集并融合多源交通数据
     */
    public void collectTrafficData(TrafficDataDTO data) {
        // 1. 数据校验
        if (data.getRoadId() == null || data.getCollectionTime() == null) {
            log.warn("交通数据缺少道路ID或采集时间，丢弃数据");
            return;
        }

        // 2. 数据标准化处理
        TrafficDataStandardized standardizedData = dataStandardizer.standardize(data);

        // 3. 发送到Kafka进行实时分析
        kafkaTemplate.send(TRAFFIC_DATA_TOPIC,
                data.getRoadId().toString(), JSON.toJSONString(standardizedData));

        // 4. 缓存道路实时状态
        String statusKey = ROAD_STATUS_KEY + data.getRoadId();
        redisTemplate.opsForValue().set(statusKey, standardizedData, 5, TimeUnit.MINUTES);

        // 5. 批量存储历史数据
        trafficDataBatchCollector.collect(standardizedData);
    }

    /**
     * 实时交通态势分析与预警
     */
    @KafkaListener(topics = TRAFFIC_DATA_TOPIC, groupId = "traffic-situation-processor")
    public void analyzeTrafficSituation(ConsumerRecord<String, String> record) {
        try {
            String roadId = record.key();
            TrafficDataStandardized data = JSON.parseObject(record.value(), TrafficDataStandardized.class);

            // 1. 路段状态评估
            RoadStatus status = roadStatusEvaluator.evaluate(roadId, data);

            // 2. 异常事件检测
            TrafficAnomaly anomaly = anomalyDetector.detect(
                    roadId, data, getHistoricalData(roadId, data.getCollectionTime(), 30));

            // 3. 拥堵趋势预测
            CongestionPrediction prediction = congestionPredictor.predict(
                    roadId, data, status, getWeatherCondition(roadId, data.getCollectionTime()));

            // 4. 生成态势报告
            TrafficSituationReport report = new TrafficSituationReport();
            report.setReportId(UUID.randomUUID().toString());
            report.setRoadId(roadId);
            report.setReportTime(LocalDateTime.now());
            report.setCurrentStatus(status);
            report.setAnomaly(anomaly);
            report.setCongestionPrediction(prediction);

            // 5. 异常预警处理
            if (anomaly.isAnomalyDetected() || prediction.getCongestionLevel() >= CongestionLevel.SEVERE) {
                triggerTrafficAlert(report);
            }

            // 6. 更新路网全局态势
            trafficSituationManager.updateRoadStatus(roadId, report);

        } catch (Exception e) {
            log.error("交通态势分析失败", e);
        }
    }
}

        if (request.getLineId() == null || request.getDate() == null) {
            throw new BusinessException("调度计划缺少线路ID或日期");
        }

        // 3. 可用资源评估
        VehicleResource vehicles = vehicleService.getAvailableVehicles(
                request.getLineId(), request.getDate());
        DriverResource drivers = driverService.getAvailableDrivers(
                request.getLineId(), request.getDate());

        // 4. 基础调度计划生成
        DispatchPlan plan = dispatchAlgorithm.generateBasePlan(
                request.getLineId(), request.getDate(), demand, vehicles, drivers);

        // 5. 计划优化调整
        DispatchPlan optimizedPlan = dispatchOptimizer.optimize(
                plan, demand.getPeakPeriods(), request.getPriorityFactors());

        // 6. 保存调度计划
        optimizedPlan.setPlanId(UUID.randomUUID().toString());
        optimizedPlan.setCreateTime(LocalDateTime.now());
        optimizedPlan.setStatus(PlanStatus.DRAFT);
        dispatchMapper.insertDispatchPlan(optimizedPlan);

        // 7. 缓存调度计划
        String planKey = DISPATCH_PLAN_KEY + optimizedPlan.getPlanId();
        redisTemplate.opsForValue().set(planKey, optimizedPlan, 3, TimeUnit.DAYS);

        return optimizedPlan;
    }

    /**
     * 实时调整调度计划
     */
    public DispatchAdjustment adjustDispatchPlan(String planId, AdjustmentTrigger trigger) {
        // 1. 获取当前计划
        DispatchPlan currentPlan = dispatchMapper.selectById(planId);
        if (currentPlan == null) {
            throw new BusinessException("调度计划不存在");
        }

        // 2. 分析调整需求
        AdjustmentAnalysis analysis = dispatchAnalyzer.analyzeAdjustmentNeed(
                currentPlan, trigger, getRealTimeData(currentPlan.getLineId()));

        // 3. 生成调整方案
        DispatchAdjustment adjustment = dispatchAlgorithm.generateAdjustment(
                currentPlan, analysis);

        // 4. 保存调整记录
        adjustment.setAdjustmentId(UUID.randomUUID().toString());
        adjustment.setPlanId(planId);
        adjustment.setAdjustTime(LocalDateTime.now());
        adjustment.setTriggerReason(trigger.getReason());
        dispatchMapper.insertDispatchAdjustment(adjustment);

        // 5. 更新原计划状态
        dispatchMapper.updatePlanStatus(planId, PlanStatus.ADJUSTED);

        // 6. 发布调度指令
        publishDispatchCommands(adjustment);

        // 7. 更新缓存
        String planKey = DISPATCH_PLAN_KEY + planId;
        redisTemplate.delete(planKey);

        return adjustment;
    }
}

        TripStatus status = tripTracker.updateProgress(planId, progress);

        // 3. 检查行程异常
        TripAnomaly anomaly = tripAnomalyDetector.detect(plan, status, progress);

        // 4. 生成调整建议
        List<TripAdjustment> adjustments = new ArrayList<>();
        if (anomaly.isAnomalyDetected()) {
            adjustments = tripAdjuster.generateAdjustments(plan, status, anomaly);
        }

        // 5. 保存行程状态
        tripStatusMapper.updateStatus(planId, status, adjustments);
