上海警方在全国首创“交通治堵大模型” 目前试点路口平均车速提升12.9%

Core Insights - Shanghai police have launched a pioneering "Traffic Congestion Control Model" that can quickly detect traffic congestion, accurately analyze its causes, and generate comprehensive strategies for alleviating congestion [1][2] - The model has been deployed at 360 intersections in Shanghai, resulting in an average speed increase of 12.9% at these locations [1][2] Group 1: Model Development and Features - The "Traffic Congestion Control Model" builds on the existing "Easy PASS" system, which addresses four key congestion issues: where congestion occurs, why it happens, how to alleviate it, and the effectiveness of measures taken [1] - The model has undergone five rounds of optimization, achieving an accuracy rate of 96.7% in congestion alerts [1] - It has learned from over 950,000 pieces of traffic management knowledge, enabling it to generate traffic signal control plans after 48 rounds of tuning [1] Group 2: Implementation and Results - By the end of December 2025, the model will be applied at 360 intersections, with initial results showing an increase in average speed from 21.87 km/h to 24.53 km/h, a 12.9% improvement [2] - At the Chang Hai Road and Heng Ren Road intersection, the model identified congestion caused by a saturated parking lot, leading to a 51.2% increase in average speed from 17.5 km/h to 26.4 km/h despite a 19.1% increase in traffic flow [2] Group 3: Future Plans - Shanghai police aim to deploy the model at over 1,800 intersections by the end of October 2026 [3]
