§ Mr. SpearingTo ask the Secretary of State for Transport if he will prepare and place in the Library a map showing the principal locations of traffic lock or congestion in London for the year 1989 or other convenient period, indicating for each the principal causes of such conditions.
§ Mr. ChopeI refer the hon. Member to my Department's report "Traffic Speeds on London Roads", published in November 1989, which shows speeds on the strategic network in London, and to the reports of stage 1 of the London assessment studies published in December 1986 which identified problems on the road network in the study areas and their causes. I am placing in the Library a map showing the location of congestion on the trunk road network identified by the Metropolitan police.
§ Mr. SpearingTo ask the Secretary of State for Transport if he will list the range of passenger car units per hour per lane currently flowing on routes in London likely to be designated as red routes; and the range of respective increase in flow he expects after their designation.
§ Mr. ChopeTraffic flows vary very widely, depending on the characteristics of the road and the time of day. It is therefore not possible to provide meaningful figures in this form. An objective is to encourage traffic to use the priority routes rather than unsuitable residential roads. We shall be monitoring the pilot scheme to observe the effects on traffic flows through the area.
