§ Mr. LlwydTo ask the Secretary of State for Transport what steps have been taken to date to secure that(a) the motorway network and (b) the trunk road network in the United Kingdom are equipped with automatic incident detection and signalling technology.
§ Mr. Kenneth CarlisleWith only minor exceptions the motorway network in England is equipped with signals. The provision of signalling technology on all purpose trunk roads is governed by safety-related needs.
The installation of automatic incident detection and signalling on sections of motorway where traffic flows are heavy has been approved in principle and a programme for installation is being identified. I have no plans to provide automatic incident detection and signalling technology on all-purpose trunk roads.
