1. Introduction
During road works involving road opening, roadwork contractors or utilities undertakers (UUs) may encounter traffic installations, such as loops, cables or ductworks installed in public roads and footpaths. Where necessary, such installations will have to be diverted or disconnected on site and the roadwork contractors or UUs may wish to ascertain their ownership or managing agents because the traffic installations are not necessarily managed by the Transport Department (TD) alone. They may be managed by others. The following will provide guidelines for identifying and handling the installations, either managed by TD or not, that are found in public highways, both during normal road works situation and emergencies. Emergency situations are those incidents involving significant consequences that need immediate attention.
At present, some public roads are designated as Control Areas, such as Tunnel Areas, Tsing Ma Control Areas, etc. In the Control Areas, incidents are handled by the Operators of the Control Areas, whilst Government Departments will handle incidents outside the Control Areas. Therefore Para 2 below will describe how to deal with the installations inside Control Areas, and Para 3 will deal with the installations outside Control Areas.
Where appropriate, the descriptions will be illustrated by photos showing the various traffic installations that may be encountered. In general, the roadwork contractors or UUs should first refer to the photos for initial recognition of the particular type of traffic installations found on site. If necessary, further enquires should be made to the Control Area Operators or relevant Government Departments where appropriate. TD’s First Contact Point at 2410 0066 (24 hours) can assist in identification of installations outside Control Areas in case of emergencies. The enquirers should indicate the name of the streets or junctions
