HC Deb 05 February 2001 vol 362 cc378-9W
Mr.Hammond

To ask the Secretary of State for the Environment, Transport and the Regions if he will publish figures indicating the average usage, on an hour-by-hour basis, of the M4 eastbound bus lane between Heathrow and the elevated section, for the most recent period for which figures are available. [147388]

Mr.Hill

As the hon. Member may be aware, the Transport Research Laboratory (TRL) has been monitoring the usage of the M4 bus lane for the Highways Agency. The most recent period for which TRL has provided figures of average usage on an hour-by-hour basis is the week beginning 5 June 2000. Those figures are as follows:

Time of day Taxi Minibus Bus/coach Total
00:00 7 0 0 1
01:00 2 0 0 2
02:00 1 0 0 1
03:00 1 0 1 2
04:00 2 0 3 5
05:00 42 2 8 52
06:00 193 10 21 224
07:00 286 17 43 346
08:00 238 11 30 279
09:00 253 9 39 301
10:00 259 9 45 313
11:00 188 7 33 228
12:00 200 10 32 242
13:00 190 7 29 226
14:00 181 8 28 217
15:00 175 5 23 203
16:00 211 9 48 268
17:00 205 8 46 259
18:00 242 6 28 276
19:00 242 4 17 263
20:00 231 4 13 248
21:00 238 3 10 251
22:00 178 2 8 188
23:00 64 0 3 67
Total 3,829 131 508 4,468

On average, 3,700 vehicles per day used the bus lane during the first year of operation. It is worth noting that, while this represents an average of 7 per cent. of the traffic on the M4 in to London, the vehicles carried 21 per cent. of the people using the road. During peak periods, each bus has saved on average 3.5 minutes and each car has saved on average 1 minute. Journey times for all vehicles have become more reliable following the introduction of the bus lane.

A copy of a report entitled, "Monitoring of the M4 Bus Lane: The First Year" prepared by TRL for the Highways Agency covering the first year of operation from June 1999 to May 2000 is available in the House of Commons Library. A synopsis of the report with the same title is also in the Library and it is available on the Highways Agency's website.
