public on the internet and through mobile phones. More cameras are being installed to cover other strategic locations.

A computerised 'Area Traffic Control (ATC) system is connected to the traffic signalling system in a district, enabling better control of traffic in accordance with the changing conditions on the road. By the end of 2011, there were ATC systems operating in the urban areas and in the new towns at Tsuen Wan, Kwai Tsing, Sha Tin, Ma On Shan, Tai Po, North District, Tuen Mun, Yuen Long and Tseung Kwan O.

At year-end, a total of 1 809 traffic signals was in operation at road junctions, 1 710 of which were linked to ATC systems.

Conventional traffic signals are being replaced by light emitting diode traffic signals for environmental reasons and cost savings. Replacement work in Kowloon was completed in March 2011 while works in the New Territories started in December 2010 and is expected to be completed by the end of 2012.

To facilitate traffic monitoring and incident management, traffic control and surveillance (TCS) facilities, such as CCTV, emergency telephones and lane signals, are provided in all tunnels. To enhance operational efficiency further, more TCS facilities such as variable message signs, variable speed limit signs and automatic incident detection systems have been installed, or are being retrofitted in some tunnels. The Tsing Ma Control Area, Tsing Sha Control Area and Kong Sham Western Highway are also equipped with TCS facilities.

The Red Light Camera System was further expanded to combat red light jumping at signalised junctions. There are now 155 digital red light cameras in operation throughout the territory. To enhance further the deterrent effect and strengthen the enforcement against speeding, the 'Speed Enforcement Camera (SEC) System' is being expanded. The SEC Phase 2 expansion project is scheduled for completion in 2012. Upon its completion, a total of 20 digital camera units will be operated in 120 camera housings on a rotational basis.

Five speed map panels will be installed in the New Territories to advise motorists about congestion levels along alternative routes and estimated journey time. information on a map-type display. The project is scheduled for completion by mid- 2012.

A 'Traffic and Incident Management System' is being developed to improve efficiency and effectiveness in managing traffic and transport incidents and in disseminating traffic and transport information to the public. The project is scheduled for completion in 2015.

Automatic Toll Collection

Automatic toll collection (autotoll) systems were installed at all tunnels and at the Lantau Link. The systems allow motorists with tags on their vehicles to drive through designated toll booths without having to stop to pay. Since October 1998, these autotoll systems have been unified so that a subscriber needs only one tag to use all tunnels and toll roads fitted with the system. About 48 per cent of motorists used autotoll when passing through the tunnels and toll roads in 2011.
