I refer to Suresh Khilari's letter headlined, 'Toll slip-up proves costly' (South China Morning Post, March 1), concerning his experience in using the autotoll facility at Tate's Cairn Tunnel.
At present, five road tunnels, including the Tate's Cairn Tunnel, are installed with either 'Autopass' or 'ETS' electronic toll collection systems which are being provided by two different suppliers.
To guide motorists in the use of autotoll lanes in tunnels, two large signs are erected above the toll booth on each autotoll lane. The first is an 'Autotoll Only' sign which indicates that the toll lane is designated as an autotoll lane and only motorists with the valid electronic tags may use the lane.
The second sign, placed immediately above the first one, shows the autotoll system sign (that is, 'Autopass' or 'ETS') to inform motorists that only those subscribed to the system and issued with the specified system tags may use the autotoll lane.
Additional measures are now being considered to further improve the information about the use of autotoll tags.
The two autotoll system suppliers have been requested to publicise, in their future regular newsletters to their subscribers, the names of the tunnels which accept their tags. Additional signs indicating the relevant autotoll system for the tunnels will be erected in the toll plaza areas as far as possible.
As automatic toll collection technology is still being developed and refined, we cannot restrict the installation of a suitable autotoll system in the tunnels at this stage. However, in the longer term, we shall examine the feasibility of providing an integrated autotoll system for the tunnels.
