Highways Agency Annual Report and Accounts 2011-2012

Summary of our Performance: SECTION 2
Further details of this policy
can be found in Note 1.4 to
the accounts. The significant
under spend reflects the
difference between the prudent
assumptions used at the time
of deriving the AME write-down
budget and the actual capital
investment programme that was
subsequently agreed as part
the Spending Review.
Capital budget
The capital investment
programme has outturned very
close to the budgeted figure.
This includes a 10 per cent
efficiency saving across the
capital renewals programme
(thereby allowing additional
projects to be delivered).
Details of performance against our measures published in our Business plan are shown in the table below.
Performance against 2011-12 Business Plan Measures
HA Business Plan Measure 2011-12 2010-11 Commentary
Cost of operating the HA motorway
and A road network per vehicle mile.
Cost of maintaining the HA motorway
and A road network per lane mile.
Percentage of HA’s appraised project
spending that is assessed as good
or very good value for money.
0.3 pence 0.3 pence The results show that the cost of operating the motorway and
A road network when compared to usage of the network has
remained constant for the past two years.
£43,000 £41,000 In 2011-12 maintenance costs associated with this measure
increased by an additional 5 per cent compared with 2010-11.
This additional activity had been planned and budgeted for in
the Spending Review. The main elements of the increase were
a planned increase in the M25 PFI service payments and
increased capital renewals. Expenditure on maintenance,
particularly in relation to capital renewals, reflects the varying
demands of maintenance activity which is not necessarily
comparable year-on-year.
100% N/A This is a measure of the expected benefits for each pound of
spending covered by the appraisal process.
New measure in 2011-12.
Reliability of journeys on the HA
motorway and A road network.
83.90%
‘on time’
N/A
An ‘on time journey’ is defined as one which is completed
within a set reference time.
New measure in 2011-12.
Annual road fatalities on the HA
motorway and trunk road network.
251 249 Due to the compilation method used these figures reflect the
calendar rather than financial year.
The mean and median average
incident duration times on
motorways.
Mean 28 minutes
Median 15 minutes
(these are figures
for the month of
March 2012)

Measures the average time taken to clear incidents on
motorways. Graph showing monthly trend found on page 21.
New measure in 2011-12.

international goals for a reduction
in carbon dioxide emissions

We achieved a 9.7 per cent reduction in carbon dioxide
emissions in 2011-12. A significant proportion of this
reduction is due to a change to the Defra greenhouse gas
emission factor for electricity, however there has been a
substantial reduction in energy consumed.
The proportion of the network that is
in a condition that does not require
further investigation for possible
maintenance
95.6% N/A This measure replaces a target introduced in 2004-05 to
maintain the road surface at a specified condition.
For the programme of schemes
in the construction phase,
maintain a programme level of at
least 1.00 against the cost
performance index (CPI) and the
schedule performance index (SPI).
CPI 1.12
SPI 1.05
CPI 1.00
SPI 1.04
CPI measures the cost of work performed against the target
cost agreed with the supplier.
SPI measures the time taken against the time planned.
Exceeding 1.00 for both demonstrates that the programme of
road improvements has been delivered below target cost
and ahead of schedule.
The accident frequency rate of the
HA supply chain.
0.20 0.20 This shows the number of accidents per 100,000 hours worked.
It has remained constant for the past two years.
