Baidu Intelligent Cloud showcased its latest advancements in the traffic big model sector at the 2024 China International Big Data Industry Expo. By integrating with Baidu's traffic big data, it significantly enhanced the efficiency of omni-directional signal control, improving traffic flow by 20-30%. In the pilot project in Guiyang's Guanshanhu District, the application of AI signal control technology led to a 15% reduction in average weekday vehicle delay. This system integrates internet and local traffic police data to predict traffic flow distribution within 5 minutes and dynamically adjusts traffic light durations to optimize green light utilization.
