Replacement of Traffic Control and Surveillance System in the Tsing Ma Control Area”
For discussion FCR(2017-18)59 on 2 February 2018 ITEM FOR FINANCE COMMITTEE CAPITAL WORKS RESERVE FUND HEAD 708 – CAPITAL SUBVENTIONS AND MAJOR SYSTEMS AND EQUIPMENT Transport Department New Subhead “Replacement of Traffic Control and Surveillance System in the Tsing Ma Control Area” Members are invited to approve a new commitment of $298,910,000 for the replacement of traffic control and surveillance system in the Tsing Ma Control Area. PROBLEM The Transport Department (TD) needs to replace the traffic control and surveillance system (TCSS) in the Tsing Ma Control Area (TMCA) to maintain the safe, reliable and efficient operation of the control area. PROPOSAL 2. The Commissioner for Transport, on the advice of the Director of Electrical and Mechanical Services, proposes to replace the TCSS in TMCA at an estimated cost of $298,910,000. The Secretary for Transport and Housing supports the proposal. /JUSTIFICATION ….. FCR(2017-18)59 Page 2 JUSTIFICATION 3. The TCSS in TMCA1 is for ensuring the safe and effective operation of the control area. The existing TCSS commenced operation when TMCA was commissioned in 1997, and has already been in use for more than 20 years. According to the Electrical and Mechanical Services Trading Fund (EMSTF), it is increasingly difficult and not cost effective to carry out repairs for the TCSS. For example, the existing multimode optical fibre cables2 in the system can only provide limited bandwidth. The telecommunication industry has long been replaced them by single-mode optical fibre cables. Other relevant equipment such as prismatic variable message signs, closed circuit television (CCTV) system and emergency telephone system are also beyond their economical serviceable life. -

Information Paper on Route 8 Control Area Bill
LC Paper No. CB(1)771/06-07(06) LEGISLATIVE COUNCIL PANEL ON TRANSPORT Tsing Sha Control Area Bill PURPOSE This paper informs Members of the major components of a Bill governing the operation of the Tsing Sha Control Area, i.e. the section of Route 8 between Tsing Yi and Sha Tin. BACKGROUND 2. Route 8 is a strategic road linking Sha Tin and North Lantau. The western section of Route 8 is the Tsing Ma Control Area (TMCA) linking Tsing Yi and North Lantau, which came into operation in 1997. The remaining section of Route 8 between Tsing Yi and Sha Tin is under construction. This section is about 15 km in length, and comprises three road tunnels (Sha Tin Heights Tunnel, Eagle’s Nest Tunnel and Nam Wan Tunnel), a cable-stayed bridge across the Rambler Channel (Stonecutters Bridge), four viaducts (Lai Chi Kok Viaduct, Ngong Shuen Chau Viaduct, Nam Wan East Viaduct and Nam Wan West Viaduct), as well as several interchanges and slip roads. The alignment of Route 8 between Tsing Yi and Sha Tin is at the Annex. 3. On completion, Route 8 will provide a direct road link between Chek Lap Kok and the Northeast New Territories via Tsing Yi and Cheung Sha Wan. It will also provide additional road capacity to cope with the increasing traffic along the Lion Rock Tunnel, Tate’s Cairn Tunnel, Shing Mun Tunnels, Cheung Tsing Highway, Cheung Tsing Tunnel and Tsing Kwai Highway. 4. Our plan is that the section of Route 8 between Cheung Sha Wan and Tsing Yi will not be tolled as vehicles can leave Route 8 through the slip roads at West Kowloon, and its major alternative routes are toll free. -

Paper on Emergency Transport Arrangements After the Closure Of
立法會 Legislative Council LC Paper No. CB(4)245/15-16(02) Ref. : CB4/PL/TP Panel on Transport Special meeting on 24 November 2015 Background brief on emergency transport arrangements after the closure of Kap Shui Mun Bridge Purpose On the night of 23 October 2015, Kap Shui Mun Bridge ("KSM Bridge") connecting Ma Wan and Tsing Chau Tsai Peninsula of Lantau Island was struck by a vessel, triggering the ship impact alarms of KSM Bridge. As a result, all lanes of KSM Bridge and Tsing Ma Bridge were closed for nearly two hours to facilitate inspection by engineering staff. During the closure period, no vehicle could enter or leave the Lantau Island, and the train services of the MTR Airport Express and Tung Chung Line were also suspended. It was the first time KSM Bridge and Tsing Ma Bridge were fully closed since their opening about 18 years ago. 2. The above incident has aroused wide public concern. This paper provides background information on the Administration's contingency strategies formulated in the 1990s to cater for the closure of land link to North Lantau and the Airport. The major views and concerns expressed by Members of the Legislative Council ("LegCo") after the incident are also summarized in the paper. Background KSM Bridge 3. KSM Bridge is one of the important structures in the Lantau Link which provides a direct access to the Hong Kong International Airport at Chek Lap Kok. KSM Bridge is 820-metre long and is the world's longest cable stayed bridge carrying both road and rail traffic. -

(2004) Dynamic load monitoring of the Tsing Ma Bridge using a high-speed FBG sensor system. In Proceedings 2nd European Workshop on Structural Health Monitoring, Munich, Germany. Copyright 2004 (The authors) 1 1. ABSTRACT Sensors for strain measurement are indispensable for structure monitoring. Fiber optic sensors based on Fiber Bragg Grating (FBG) technology are found to be suitable for strain sensing and have a number of advantages compared to conventional strain gauges. Recently, we carried out a field trial with a FBG sensor array system on the world’s longest span suspension bridge carrying both trains and regular road traffic (The Tsing Ma Bridge in Hong Kong). The experiment was carried out with a high-speed dense-channel demultiplexing/interrogation system for FBG sensor arrays (DC to ~20 kHz for all channels simultaneously). This system is originally developed for the detection of high-speed events (vibration, impact location and acoustic emission), but in this field experiment the high readout frequency has been used for noise reduction by averaging to achieve sub-pm resolution. -
