Core Viewpoint - The article highlights the innovative policing strategies and technologies employed by the Changsha Public Security Bureau to ensure public safety and order during the New Year holiday, particularly in the bustling Wuyi Square area. Group 1: Policing Strategies - During holidays, a "special response" mechanism is activated, which includes a four-tier response system: regular patrols by local police, coordination by district bureaus during increased foot traffic, and city-wide inter-departmental collaboration during major holidays [4]. - The response level adjustments are supported by a "large crowd monitoring platform" that utilizes real-time data from mobile devices and video feeds to predict crowd trends, shifting from passive responses to proactive alerts [4]. Group 2: Crowd Management - The police optimized their grid management from 16 to 9, combining "key grid control" with "peripheral guidance" to prevent new crowding risks while managing foot traffic effectively [5]. - On New Year's Eve, the peak crowd in Wuyi Square reached 179,000, with a maximum of 239,000 during the holiday period. The police deployed 4,065 officers and 1,000 community support personnel across 191 duty points to maintain order and safety [5]. Group 3: Technological Innovations - The introduction of the "new police color" includes advanced equipment such as drone command vehicles that maintain communication via satellite and provide real-time aerial views to command centers, enhancing situational awareness [6]. - AI smart glasses are transforming traffic police operations, allowing officers to quickly identify vehicles and assess safety risks through voice commands, streamlining their workflow [6]. - Police drones serve as essential "aerial sentinels," capable of reaching accident scenes quickly to manage situations and prevent secondary incidents before ground units arrive [6].
