Core Viewpoint - The reconstruction and expansion of the Jingha Expressway's Shenshan section aims to enhance traffic flow and safety, incorporating advanced technologies and new traffic management strategies to accommodate increased vehicle volume and improve operational efficiency [1][2][3]. Group 1: Infrastructure Expansion - The Shenshan section of the Jingha Expressway will add four lanes, resulting in a total of ten lanes for two-way traffic, significantly improving traffic flow [4][5]. - The project is expected to complete earlier than planned, with the Beijing direction anticipated to open by late July and full dual-direction operation by the end of September [1]. Group 2: Smart Technology Integration - The Shenshan section features a comprehensive smart highway system, including 32 platforms and 84 algorithms for real-time monitoring of traffic and environmental conditions, utilizing AI for video analysis and weather monitoring [3]. - Drones have been deployed along the highway to enhance surveillance and emergency response capabilities, with 27 drone nests installed for automated patrols [2]. Group 3: Traffic Management Innovations - New traffic management features include the introduction of a left-side hard shoulder for emergency stops and a tidal lane system to optimize traffic flow between passenger and freight vehicles [4][5]. - The tidal lane will dynamically adjust based on traffic conditions, allowing for flexible use of lanes depending on the volume of passenger and freight traffic [5]. Group 4: Safety Enhancements - The reconstruction includes new M-type guardrails designed to improve safety by reducing the risk of vehicle crossover and minimizing injury during accidents [6]. - Additional safety features such as mileage markers and warning signs have been implemented to assist drivers in accurately identifying their location and preparing for lane changes [6][7].
