SYDNEY CBD EMERGENCY EVACUATION SYSTEM

摘要

In the wake of the 2004 Madrid and 2005 London terrorist bombings, the NSW Government and the City of Sydney identified a requirement to implement a rapid response emergency information system to ensure public awareness, public safety and highlight emergency evacuation routes within the City should the need arise. In reviewing the aftermath of the bombings, the ability to alleviate mass panic proved paramount, immediate situational warnings and advice must be delivered to rail passengers in the proximity of adjacent stations, station approaches, city workers and the public. The Sydney CBD system required high visibility Variable Message Signs (VMS) to be installed at strategic points within the CBD and railway station entrances coupled with loud-speaker groupings to immediately alert the public of an emergency or exigent situation. The entire system is controlled from a single control centre. The New South Wales Roads and Traffic Authority (NSW RTA), Intelligent Transport Systems (ITS) was tasked to design a system capable of panoptic coverage of Sydney’s Central Business District (CBD), deliver long-term reliability and efficient performance with minimal maintenance requirements. ITS’s specialisation is the design of high visibility electronic safety, advisory or warning signage. This study highlights the importance of providing immediate, efficient mass warning(s) and evacuation advice throughout the CBD via a single system. As this system is the first to be installed in Australia, ITS’s system analysis, project methodology, costings, design/development, strategic placement and control processes for the scrolling Variable Message Signs (VMS) and loud-speaker systems are discussed. This study examines the infrastructure and installation requirements necessary to implement the system, specifically it will; 1. Describe the processes and modelling analysis used to design and implement a line-of-sight radio communication system to overcome the constraints of high-rise buildings within Sydney’s CBD. 2. Describe the analysis and modelling undertaken for the strategic siting of VMS’s and loud-speaker groupings within the CBD. 3. Describe the public awareness campaign undertaken to educate the public regarding the system’s importance to their safety. 4. Describe the upgrades identified to maintain the system’s efficiency in line with technology changes, and. 5. Describe the custom built control software and explain emergency agency/control centre responsibilities. This is the first emergency information system designed and installed in Australia and the project’s processes and strategic analysis to achieve immediate use combined with long term IP1-Roychoudhry-E Page 2 reliability will provide an efficient knowledge base for projects requiring comparable outcomes in equipment and solutions, both in Australia and internationally. In French Ouvert en 1932, le Sydney Harbour Bridge (SHB) n'a guère été con?u pour supporter le volume actuel de circulation routière. La croissance exponentielle du trafic a nécessité le remaniement des couloirs de circulation et du contr?le de routier) afin d’utiliser au mieux les voies sans nuire à la sécurité des utilisateurs. Le projet (pour trouver la solution d’ une sécurité routière maximale, aussi bien pour les équipes rattachées au pont que pour les conducteurs, a été confié à une division de l’autorité Roads and Traffic Authority, l’ITS. Le domaine d’expertise d’ITS Manufacturing est le design de panneaux routiers électroniques de haute visibilité. Cette étude analyse l'importance de la capacité du SHB de transporter efficacement tout véhicule sur le pont qui traverse la baie de Sydney. Elle presente egalement sa capacité A utiliser les panneaux électroniques à message variable et les panneaux de limitation de vitesse pour communiquer aux conducteurs tout changement de configuration des couloirs de circulation d? aux travaux de maintenance ou aux acciden
