一、智慧交通核心场景的技术突破

智慧交通系统的特殊性在于“高并发数据处理、多源数据融合、实时决策响应”。飞算JavaAI针对交通业务特性，打造了专属交通引擎，实现通行效率与出行体验的双向提升。

1.1 交通态势感知与智能预警系统

交通监测需要实时掌握路网运行状态并提前预警异常，飞算JavaAI生成的感知系统可实现“数据采集-态势分析-异常预警-联动处置”的全流程自动化：

多源交通数据融合分析

public class TrafficSituationService {@Autowiredprivate KafkaTemplate<String, String> kafkaTemplate;@Autowiredprivate RedisTemplate<String, Object> redisTemplate;@Autowiredprivate TrafficDataMapper trafficDataMapper;@Autowiredprivate DataFusionService fusionService;// 交通数据Topicprivate static final String TRAFFIC_DATA_TOPIC = "traffic:situation:realtime";// 路网状态缓存Keyprivate 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);}}
}
