How will the success of the scheme be monitored?

    There will be a range of assessments that will need to be balanced when judging the overall success of the trial. Assessments will include:

    • Residents views on how the benefits of the scheme compare against the disbenefits
    • Data on the volume of motor vehicle movements in the area
    • Data on the speed of motor vehicles in the area
    • Impacts on the primary roads surrounding the area
    • Air quality considerations
    • Bus journey time considerations through discussion with Transport for London
    • Outcomes of ongoing dialogue with the Emergency Services


    Reporting on the trial will also consider whether the scheme supports the delivery of the Enfield Council Plan.

    We have already collected traffic data in the area, counting vehicle movements at a range of locations throughout the area, including on surrounding roads. We will repeat this process once the measures have been implemented and can start to compare the data to determine the level of success and impact.

    We will also carry out air quality modelling using traffic data collected.

    The Council has a diffusion tube at 134 Brownlow Road and at 92 Warwick Road and a real-time monitoring station at Bowes Primary, at the front of the school, facing the A406.

    The diffusion tubes are changed on a monthly basis and are for indicative monitoring. The real-time monitoring station has a nitrogen dioxide analyser and a PM10 (fine dust) analyser, both of which run 24-hours a day, 365 days of the year and are much more accurate than diffusion tubes.

    Our monitoring data from the real-time site at Bowes Primary School is available on the London Air Quality Monitoring Network: http://www.londonair.org.uk/LondonAir/Default.aspx

    Residents can download monitoring data using the ‘Tools’ tab on the front page of the website.

    Feedback from the consultation will also be analysed to develop insights into the views of the community and how they assess the benefits of the scheme against any dis-benefits. These views are likely to vary depending upon where in the area you live.

    The formal report will outline all these factors when looking to determine the overall success of the scheme.

    What is an Experimental Traffic Order?

    Experimental Traffic Orders (ETOs) enable the Council to implement the scheme on a trial basis. The scheme can be in place for a short period and removed or changed. There is no minimum length of time after the initial implementation after which the scheme can be removed or changed. However, the Council would like to ensure an appropriate amount of time to assess viability of the scheme before any decisions are made. 

    A consultation must take place during the trial period and before a decision is made on whether to remove the trial of make the scheme permanent. 

    A report will be written to summarise the feedback. Monitoring will also inform any decision made by the Council. Haringey officers will also be involved in discussions during the scheme trial period and before any decisions are made on changing the scheme or making it permanent. 

    The Council, including ward councillors are committed to undertaking a meaningful consultation that will inform our decision making for the Bowes scheme. 

    Will residents be consulted? If so, how and when can we leave feedback?

    Yes. Given the ETO nature of the scheme, the consultation with community takes place during the trial rather than ahead of the scheme being implemented.

    The Council have engaged and been in communication with emergency services, TfL and Haringey before starting the trial.

    Now that the trial is fully in place, residents and all interested stakeholders are be able to provide their comments via the statutory consultation that is key part of the process and is hosted on this page. Please go to the bottom of the main project page to take part in the consultation.

    Residents are now able to complete the survey to provide their views on how the scheme is working in practice. If they prefer, they can submit their comments in writing to the below address:


    ATTN: Healthy Streets team, Enfield Council, Civic Centre, Silver St, Enfield, EN13XA.


    To submit your comments online you will need a Let's Talk Enfield account. Click 'Sign up' in the top right corner of this page. See here for more information on the Let's Talk Enfield site.

    Consultation will also be open to Haringey residents so that we can understand their perspective too. This information will be shared with Haringey Council

    Can the trial measures be adjusted and adapted?

    Yes. This is the benefit of taking a trial approach. Owing to the urgency that the Covid-19 situation has presented, rather than spend months and even years modelling multiple scenarios and potential impacts, we are trialling an approach and can then monitor the actual impacts. We're using planters and bollards for the modal filters that can be re-located as necessary. Balancing the desires of all residents is a significant challenge and it is recognised that these kind of schemes will mean that some residents will have to take alternative routes for some journeys. 

    The scheme is implemented using an Experimental Traffic Order (ETO) enabling the Council to make temporary changes and consult with community and stakeholders during the trial. This gives the Council an opportunity to review feedback and see how the scheme operates and either make changes to the trial, remove the scheme or make it permanent. 

    Before a decision is made whether to make the scheme permanent, feedback and monitoring will be reviewed, and a formal report produced and published on our website. 

    Why have the filters been placed in their current locations?

    Engineers from Enfield Council have reviewed the road layout in the area and introduced what is believed to be the most optimal location of closure points to prevent any rat-running through the area.

    These types of schemes by nature limit access/egress points to the area in order to prevent vehicles cutting through the area.


    It is acknowledged that the introduction of this scheme will mean travelling to/from some directions will be hindered and some journeys when made by car may be longer. However, one of the aims of the scheme is to reduce the overall number of motor vehicle journeys through the area, leading to longer-term improvements in air quality and creating a safer environment for residents. 

    Are there other design options?

    The intention is to trial the existing design, but alterations can be made once we have had the opportunity to review the scheme in operation. We are already receiving feedback and suggestions on how people believe the scheme could be improved and are actively discussing these suggestions. We aim to seek feedback on how the scheme works and how it could be improved via the consultation that has now started . 

    How will emergency vehicles access the area?

    In addition to the formal statutory consultation with emergency services, discussions have taken place, in particular with the London Ambulance Service to discuss their operational requirements. The London Ambulance Service very much welcome the changes on Warwick Road itself, which removes the previous physical emergency gate at the width restriction, and replaces this with a camera-controlled closure, which emergency vehicles can pass through unhindered. The emergency services are able to use both Warwick Road and Brownlow Road to pass through the area or to access side streets within the area.

    Emergency vehicles will also continue to be able to pass through the 'Bus Gate' planned for Phase 2.

    What is a bus gate / emergency gate?

    A bus gate is a point on the road where only buses (or other authorised vehicles like emergency services) can pass through. They are typically camera enforced, meaning that if you ignore the signs and pass through the bus gate, you will receive a fine. The purpose of a bus gate is to reduce private traffic passing through a certain point, whist ensuring that a bus service is not impacted in the way it would be if the road was physically closed. An emergency gate works the same way - whilst there might not be buses on a particular route, in order to assist with the flow of emergency vehicles through an area an emergency services gate is used rather than a physical road closure. 

    These are typically enforced by a camera and any unauthorised use will result in a penalty notice. London ambulance service has told us that the existing width restriction on Warwick Road does not allow their new fleet of vehicles to pass, without needing to interrupt the journey to open the barrier. The proposed camera-controlled restriction point therefore improves this situation, ensuring ambulances have easy access into the estate from the south, as well as from the north.

    Does a bus gate mean cars will not be able to use Brownlow Road?

    No. The road will still be open to private cars, but they will not be able to pass through the actual point where the bus gate is located. The position of this is yet to be determined. It could go at the north of Brownlow Road, meaning access would be from Bounds Green Road. It could be at the southern end of Brownlow Road meaning access from the A406, or it could be part way along, allowing access from either end. Further discussion is necessary with Haringey, Transport for London and residents will be able to provide their own views as part of the Phase 1 consultation.

    How will refuse trucks and other large vehicles such as delivery vans access the area?

    Delivers / visitors to the area will use the same access points as residents. Refuse vehicles, as well as emergency vehicles, will have dispensation to be able to pass through camera enforced closures

    Will any of the roads be completely inaccessible?

    No. Vehicle access will be maintained to all roads within the area. Vehicle access may be limited to in/out of the same end of the road, but none of the roads will be completely closed to motor traffic, enabling access and deliveries to continue. 

    How do I access/exit the area if A406 is shut?

    In the rare event of the A406 being closed to traffic, the Council will suspend enforcement with the aim to avoid issuing PCNs during the period of the closure.

    However, if a fine is issued whilst the A406 is shut, please you could let us know and provide further details using this link https://parkingservices.itsvc.co.uk/enfield/notices/


    To check if there are any road closures on A406 please visit https://tfl.gov.uk/traffic/status/

    What is a modal filter?

    A modal filter is road closure for motor vehicles, but which continues to enable people to walk and cycle through the closure point. We will be using bolt-down planters to reduce the width of the road and putting in a removal bollard into the centre of the remaining gap.

    What evidence are the proposals based on?

    Enfield Council have heard concerns from residents for many years about the negative impact of excessive motor traffic passing through the area. Towards the end of 2019 we invited residents to participate in a survey to tell us what they thought were the issues. 87% of participants said the volume of traffic was a problem and 78% of participants said speed was a problem.

    Have traffic surveys been carried out in the area?

    Yes. We have historical traffic data for a number of roads in the area. Traffic surveys have also been conducted recently (ahead of scheme implementation) and will be repeated once the scheme is fully in place. This data will be analysed and historic data will be used for context and to inform the recently carried out surveys

    How do you expect the proposals to impact traffic speeds and volumes in the area?

    We anticipate that both the speed and volume of traffic will reduce within the area. The only traffic entering the area would be residents / visitors.

    What measures will be put in place to alleviate the effects of increased local traffic on the A406?

    A review of traffic on the A406 will form part of the monitoring, but one of the objectives of the scheme is to ensure that through traffic stays on main roads and does not use residential streets as a cut through. Monitoring will also take place on other surrounding roads including Bounds Green Road and Green Lanes, as well as other residential streets.

    Is this going to make things worse for Bowes Primary School?

    These proposals prevent traffic using Highworth Road as a cut through, which we think is positive for the school. It will only be residential traffic that will be entering the area, which should see an overall reduction in the amount of vehicles. We will need to make sure that we closely monitor the situation around the school as we would wish to improve the environment here not make it worse. Enfield Council are committed to improving the environment at schools across the Borough as evidenced by our School Streets project.

    What about the right-turn ban from Bounds Green Road onto the A406?

    This banned turn was introduced as part of TfL's Safety and Environmental Improvement Scheme to improve safety and to help provide the capacity so that pedestrian and cycle crossings could be provided at the junction. The feasibility of reinstating the banned turn will be explored further with both Haringey and Transport for London, although it is not anticipated that any changes could be made in the short-term. 

    What happens with access to the South of the area once Haringey implement their schemes?

    Once details of the Bounds Green LTN are known to Enfield Council we will discuss this Haringey Council to ensure collaborative approach. 

    Could Double Yellow Lines be introduced at the top end of Warwick Road to assist with access off A406?

    The introduction of double yellow lines in this area can be considered once the scheme is fully implemented and observations are made on how this junction works with what is potentially less volumes of traffic. 

    What will happen to the volume of traffic?

    We anticipate the volume of traffic within the area to reduce as it will only be local traffic accessing or visiting the area. We will need to monitor the impact on surrounding roads. However, observations from similar schemes in other areas of London has shown that not all traffic reassigns onto local strategic roads with people changing their travel behaviour by:

    • Using alternative travel modes, such as walking or cycling for shorter trips;

    • Carrying out their journeys at quieter (off-peak) times of the day;

    • Choosing to combine trips, such as a trip to the shops on the way to, or from work;

    • For longer journeys, reassigning onto the wider strategic network, away from the local area;

    • Car sharing;

    • Choosing not to make the trip at all; or

    • Altering the allocation of tasks within a household to enable more efficient trip-making.

    Are any advance warning signs being put up to assist traffic approaching the area?

    Yes. There are red and white warning signs notifying drivers of the road closed ahead. A series of bespoke warning signs are also placed on the approach to key routes. In addition, a series of signs have been proposed to provide information of ‘Access only’ to the LTN area.

    How is this project funded?

    This project is funded from the Department for Transport Emergency Active Travel fund with £100k allocated to Enfield. The DfT have stated that:

    “We expect all these measures to be delivered quickly using temporary materials, such as barriers and planters”.

    “If work has not started within four weeks of receiving your allocation under this tranche of funding, or has not been completed within eight weeks of starting, the Department will reserve the right to claw the funding back by adjusting downwards a future grant payment to your authority. This is also likely to have a material impact on your ability to secure any funding in tranche 2”.

    Is funding available to make changes during the trial?

    Yes. The Council have created a contingency fund ring-fenced in the Council Capital Highways funding allocation, which will be held in reserve to ensure appropriate resources are available for adjustments to be made during the Quieter Neighbourhood trials. We are committed to making adjustments where necessary and will ensure funding is available to enable this.

    Has an Equality Impact Assessment been carried out?

    Yes. An Equalities Impact Assessment (EQIA) has been carried out and a copy of this can be found in the library on the right-hand side of the main project page. This is a live document that is anticipated to be updated throughout the life of the project. Any new information gathered during the consultation and the trial will be considered in the decision-making process and the EQIA will be updated periodically accordingly. If you are aware of issues that are not reflected in the EQIA then you will be able to raise them in the consultation or can e-mail them to healthystreets@enfield.gov.uk

    How are you monitoring air quality?

    The Council has a diffusion tube at 134 Brownlow Road and at 92 Warwick Road and a real-time monitoring station at Bowes Primary, at the front of the school, facing the A406.

    The diffusion tubes are changed on a monthly basis and are for indicative monitoring. The real-time monitoring station has a nitrogen dioxide analyser and a PM10 (fine dust) analyser, both of which run 24-hours a day, 365 days of the year and are much more accurate than diffusion tubes.

    Our monitoring data from the real-time site at Bowes Primary School is available on the London Air Quality Monitoring Network: http://www.londonair.org.uk/LondonAir/Default.aspx

    Residents can download monitoring data using the ‘Tools’ tab on the front page of the website.

    Feedback from the consultation will also be analysed to develop insights into the views of the community and how they assess the benefits of the scheme against any dis-benefits. These views are likely to vary depending upon where in the area you live.

    The formal report will outline all these factors when looking to determine the overall success of the scheme.
