SUPPORTING INFORMATION
1. Two valid petitions, signed mainly by residents of Edinburgh Drive, Ickenham have been
submitted to the Council. As both petitions are broadly focussed on the same location and
similar concerns, it seems appropriate to consider both requests at the same time. The
Cabinet Member may be interested to hear that a third petition from Edinburgh Drive has
also been submitted but unfortunately did not meet the Councils’ threshold to be considered
as valid.
2. The first of the valid petitions has been signed under the following heading
“Request for a one-way system and traffic calming measures, Edinburgh Drive
We the undersigned petition the Hillingdon Council to install a one -way system and traffic
calming measures in Edinburgh Drive”
The lead petitioner also helpfully provided the following information:
We, the residents of Edinburgh Drive, urge the Council to take immediate action to address
the dangerous traffic conditions on our road.
Edinburgh Drive is frequently used as a cut-through to Glebe Avenue or as an access point
to the main road. Drivers, particularly those coming from Long Lane and the high school
side, often speed through is residential area. The bend in the road creates a blind spot,
leading to hazardous situations where the vehicles are forced onto the pavement to pass.
This has resulted in aggressive behaviour from some drivers and poses a serio us risk to
pedestrians and residents.
It is deeply concerning that a neighbour tragically lost their life on the slip road off Glebe
Avenue before any action was taken by the Council. We do not want to see another
preventable tragedy occur.
We respectfully request that the Council prioritised this issue and implements necessary
changes without delay”.
3. The second petition has been signed under the following heading:
4. “Speed bumps”
Petition Hearing – 21 May 2025 Page 3
Part I – Public
5. For completeness the third petition, was signed by one resident under the following heading:
“We the undersigned petition Hillingdon Council to place speed bumps along Edinburgh
Drive to slow down drivers that use the road to cut-through traffic on Long Lane during rush
hour.”
6. In addition, the following information was submitted:
“Although the council’s traffic report came back with insufficient evidence to support the
argument for speed bumps due to the average speed of traffic being below the threshold,
we believe that the “average speed” has no correlation with the risk of life that is caused
when non-residents decide to use our road as cut through during the busiest time of the
evening. Cars are exceeding the reside ntial limit just to beat 2 -3 minutes of traffic and
causing a huge risk to residents of the area.
The road is often busy as this time, with Douay Martyrs children walking to Ickenham Station,
the local bus stop, or to parents’ cars parked along the road. We have elderly residents who
walk to and from Ickenham shops and young children who enjoy using the front of their
houses to play. These residents no longer feel safe outside the front of their homes, as a
direct result of this fast-moving traffic.”
7. Officers have interrogated the most recently available official police recorded collision data
for the last five years and there have been no recorded incident s on Edinburgh Drive .
However, this data may not include any recent collisions or crashes that the emergency
services do not attend and so do not form part of the Police database records.
8. Both petitions mention so-called ‘speed bumps and traffic calming measures ’; if by these,
as seems likely, petitioners are thinking of the older type of round-topped narrow transverse
road humps – often known colloquially in the past as ‘sleeping policemen’ - then the Cabinet
Member will be aware that the vast majority of councils, Hillingdon include d, have not
introduced these particular types of measure for many years.
9. Having said that, various forms of traffic calming features could be considered , where
appropriate, if there is a case for them. However, petitioners may wish to consider that such
features can sometimes have the unintended effect of increasing noise from passing traffic,
notably skip lorries and similar commercial vehicles which may carry loose loads.
10. Horizontal traffic calming measures , such as c hicanes and similar measures , are seldom
suitable for the average residential road; they can cause loss of parking , are visually
intrusive and are less effective at actually reducing the speeds, of cars and vans in particular.
The Cabinet Member may wish to advise the petitioners to consider these factors in their
own deliberations and it should be noted that any form of physical measures can prove to
be ‘popular’ and ‘unpopular’ in equal measures.
11. The Cabinet Member may be aware that independent speed and traffic surveys were
undertaken in January/ February 2024 and a table of the results are attached below:

12. This chart shows that the 85% of speeds in Edinburgh Drive were found to be between 23
and 27 mph. The 85th percentile is the speed at which or below 85% of vehicles are travelling
within the road segment. As one of the petitions made reference to ‘average speeds’, it is
perhaps worth noting that the 85 th percentile speed is as a rule somewhat higher t han a
simple ‘average’ and is also used internationally as a reliable statistical tool to help assess
speed patterns.
13. However, it is appreciated that traffic patterns may evolve over time, and so subject to the
above the Cabinet Member may be minded to commission further independent 24/7 speed
and traffic surveys on Edinburgh Drive at locations agreed with petitioners and Ward
Councillors. This would then result in two sets of data representing traffic patterns in
Edinburgh Drive.
14. As the Cabinet Member will be aware , independent traffic surveys are a reliable and well -
established means to understand the real situation on the ground. These surveys generally
use specialist equipment, including pneumatic tubes which are mounted temporarily on the
road surface, fitted transversely across the whole width of the carriageway. These devices
are installed for a period of at least a week or ten days and monitor traffic movements on a
’24/7’ basis. The d iscreet equipment is sufficiently sophisticated such that not only can it
record traffic speeds at any given time, but also records the size and type of vehicles, from
motorcycles to large multi-axel lorries.
15. Petitioners have suggested im plementing a one-way system and whilst the introduction of
one-way working is feasible and can prove to be a useful traffic management tool in certain
circumstances, there are nevertheless two important factors which also need to be borne in
mind.
16. Firstly, whilst the introduction of a one-way working would undoubtedly remove the
attractiveness of the route through Edinburgh Drive for some drivers, this could also impact
directly on residents in adjacent roads such as The Paddock and Edinburgh Close and
possibly over a wider area.
17. It is appreciated that some residents who signed the petition do not live on Edinburgh Drive
and whilst it is helpful that the lead petitioner has sought the views of nearby roads, it would
be imp ortant to establish, through consultation on detailed proposals , that there is
widespread support for such a change from the wider community, which will , in turn ,
determine the success of any scheme.

Part I – Public
18. The second factor which should be borne in mind is that a possible unintended side effect
of the introduction of a one-way working is usually the increase in average traffic speeds.
With one -way working, drivers will often inevitably travel more quickly in the certain
knowledge that they will not meet oncoming traffic.
19. In order to counteract this, some form of traffic calming measures, such as the ones
suggested in both petitions, often prove necessary to try to coun teract such increases in
traffic speeds. There is of course a further risk that even if traffic calming is added, a one-
way working could increase ‘rat-running’ at certain times, in the knowledge that drivers will
not meet any opposing traffic flow . Finally, on this point, as the Cabinet Member will be
aware, traffic calming can have unwelcome nuisance impacts if, for example, large
commercial vehicles (in particular skip lorries) use the road.
20. The above points are set out in order to ensure that som e possible consequences of the
introduction of a one-way working are understood from the outset of any investigations and
deliberations with petitioners.
21. It is also recommended that if they have not already done so, residents raise their concerns
directly with the Metropolitan Police because they alone have the necessary powers to
tackle speeding and inconsiderate driving in general (if this is the case in Edinburgh Drive)
through enforcement. Physical traffic calming and traffic management can be effective tools,
but as mentioned previously, it can also have unwelcome side effects including an increase
in noise caused by traffic passing through.
Financial Implications
Subject to the outcome of discussion with petitioners, the Cabinet Member may request the
commissioning of speed and traffic surveys. The current cost of these is c.£85 per location, with
spend managed through the existing Transportation revenue budgets.

CORPORATE CONSIDERATIONS
Corporate Finance
Corporate Finance has reviewed the recommendations to this report and concurs with the
financial implications as set out above.

Legal
Legal Services confirm that t here are no specific legal implications to following the
recommendations within this report in relation to the petitions received for traffic-calming
measures and a one-way system on Edinburgh Drive, Ickenham.
A meeting with the petitioners is in line with the Council’s constitution and is a perfectly legitimate
as part of a listening exercise, especially where consideration of the policy, factual and
engineering issues are still at a formative stage. Public law principles provide that there must be
no predetermination of a decision in advance of any wider consultation. Therefore, decision
makers must ensure there is a full consideration of all representations arising , including those
which do not accord with their own.
Should there be a decision that the road measures are to be considered further, then the relevant
statutory provisions for these measures will have to be identified and considered.
Comments from other relevant service areas
None at this stage.
