Public Project Management Visualization And Evaluation Of Early Warning Systems Management

Urban road traffic tunnel is a closed space, unlike the open road. The traffic inside the tunnel horizon, air quality, traffic accidents are subject to restrictions such as emergency response, building a reliable and efficient early warning system helps visual traffic safety in tunnels, urban transport system for the protection of the normal operation of major significance.This paper compares the domestic and urban highway tunnel early warning system, an overview of the development of early warning systems for urban highway tunnel and the design process framework system, combined with 13 in service tunnel Hangzhou field research data collected from the hardware, the tunnel early warning and tunnel management, inspection, assessment of visual warning system maintenance and management model, constructed on the basis of the existing security forecast the feasibility of early warning systems, and tunnel safety management elements of the visual alert to early warning system on the City Tunnel standardized and systematic theory and data support provided to improve the level of the tunnel control and operational management to ensure the safety of the tunnel with the theoretical and practical value...
