§ Mr. William PowellTo ask the Secretary of State for Transport what improvements to traffic flow were achieved in Greater London during 1988 on(a) the A10, (b) the A 11, (c) the A 12 and (d) the A 13;
(2) what improvements to traffic flow are expected to be achieved in the Greater London area on (a) the A10, (b) the A11, (c) the Al2 and (d) the A13 during the current year.
§ Mr. Peter BottomleyIn 1988 three trunk road schemes were completed on A10 and A 13 to improve traffic flow.
These were:
- A10—Bullsmoor lane junction improvement
- A13—Roding bridge
- A13—Becton flyover tidal flow scheme.
The tidal flow scheme was particularly successful in improving traffic flow.
The Department's national trunk road programme includes 12 major improvement schemes for the four routes. A further number of smaller improvement schemes are planned for 1989–90 These include:
A12/A127—Gallows corner roundabout: installation of traffic control signals; and other small-scale junction improvements on A12.
A13—Tollgate road junction; and eight other schemes to improve traffic flow on A13, some as interim measures in advance of major schemes.
Computerised control of traffic signals by the MOVA (Modernised optimised vehicle actuation) system will be introduced this year to aid traffic flow at four junctions:
A10—Great Cambridge road/Carterhatch lane.
735WA12—Eastern avenue/Whalebone lane.
A12—Colchester road/Goosehayes drive/Gubbins lane.
A14—junction with A117 under Becton flyover.
