DTLR MONITORING OF
The particular 20 zone referred to may well
be the one in the DTLR programme (Bricknell Avenue). We don't
plan to monitor these schemes because they are largely tried and
tested. TRL carried out extensive monitoring of over 200 schemes
and their report number 215 published in 1996, on Monitoring traffic
calming in 20 mph zones is given as a reference in the DTLR memorandum
to the Committee.
Other than to ask the authorities to furnish
us with such accident and speeds data as they should already be
collecting we do not plan further monitoring.
What may be of more interest to the Committee
is Kingston Upon Hull City Council's track record on delivery
of 20 zones over the past 10 years.
There are now 85 established 20 zones
within the city, covering 162 km of road, approximately 500 streets,
23 per cent of all roads in the city. Approximately 10 schemes
per year are currently being installed.
Between 1990 and 2000 the total casualty
numbers (authority wide) have declined from 1,844 to 1,282.
Their monitoring of established schemes
(those in place for 36 months or more) shows an average 56 per
cent casualty reduction, 75 per cent for child casualties (both
figures all severities).
All schemes have been developed in
close consultation with residents, elected members, bus companies
and the emergency services.
More information might be obtainable, but we
believe that offered here gives a sufficiently positive picture
of the benefits. The results are consistent with those of TRL
