Within the UK, Low Site visitors and Clear Air Neighborhoods are serving to to advertise energetic journey by bettering security for weak street customers, whereas additionally lowering air air pollution and site visitors congestion in residential areas. Lloyd Fuller takes a take a look at how native authorities authorities are overcoming the challenges of implementing and implementing these schemes
A method during which site visitors managers can enhance security for weak street customers (VRUs) is by lowering the amount of motorized site visitors on roads. This is among the ideas behind the UK’s Low Site visitors Neighbourhoods (LTNs). LTNs are outlined in UK statutory steering as “an area-wide site visitors administration scheme geared toward lowering or eradicating by means of site visitors from residential areas” utilizing signed restrictions or bodily obstacles.
Though LTNs have been first conceived within the Nineteen Sixties, that they had a growth throughout Covid as decreased automobile use made them straightforward and fashionable to implement. Since then, whereas site visitors ranges have surged again, many LTNs have remained and extra are deliberate, with improved security, cleaner air, more healthy transport choices, and less-congested streets cited as advantages. Nonetheless, post- Covid their recognition with the general public has waned.
Within the Royal Borough of Greenwich, in Southeast London LTNs kind a part of a wider energetic journey technique. “Everyone knows the advantages of energetic journey and the way switching extra journeys to sustainable transport is essential in addressing the triple risk of local weather change, congestion and clogged lungs,” says Councillor Averil Lekau, cupboard lead for local weather motion, sustainability and transport, Greenwich Council.

LTNs have not too long ago been applied throughout East and West Greenwich, utilizing an experimental site visitors order with an 18-month analysis interval, and costing the council £1 million, supplemented by £2.1 million from Transport for London. These areas face among the borough’s worst congestion and air high quality points.
“Greenwich has the fourth highest fee in London of newborns being admitted to hospitals for respiratory tract diseases,” says Lekau. “Air air pollution in lots of elements of our borough is properly above World Well being Group limits. We wouldn’t drink soiled water so why ought to we breathe soiled air?”
Nationwide steering
The UK’s Division for Transport’s statutory steering on implementing LTNs, revealed in March 2024, emphasizes the important significance of neighborhood engagement.
“Analysis exhibits that, whereas (LTNs) can work, in the proper place, and, crucially, the place they’re supported, too typically native folks don’t know sufficient about them and haven’t been in a position to have a say,” wrote then-Secretary of State for Transport Mark Harper in his foreword to the steering. “More and more and frustratingly, we see bigger and bigger low-traffic schemes being proposed by some councils regardless of concerted opposition by native residents and by native companies, and in some instances being eliminated once more. This steering makes it clear that ought to not occur.”

In Greenwich the steering has helped to tell the strategy to implementation. “We’re dedicated to addressing residents’ considerations and to regulate our schemes the place needed,” says Lekau. “We’re repeatedly monitoring the impression of our schemes and utilizing information to tell our choice making.”
The statutory steering outlines that good engagement ought to give the entire neighborhood the chance to be concerned and be consultant, stating: “an authority must be assured {that a} scheme is able to carrying the help of a majority of the neighborhood earlier than introducing it.”
In Greenwich the pilot represents a part of the engagement. “It’s difficult. We’re getting a whole lot of kickback, however I believe it’s necessary to see how the experimental site visitors order goes and provides it some probability to get some outcomes,” says Lekau.
A few of the approaches advisable within the steering for partaking native communities within the roll out of LTNs embrace in-person occasions within the affected space, on-line engagement and data leaflets. “We’re repeatedly monitoring the impression of our schemes and utilizing information to tell our choice making,” says Lekau.
“It’s certainly one of our most necessary missions – to make it simpler and safer and greener to maneuver across the borough,” says Lekau. “Greenwich performs an energetic function in tackling local weather disaster and bettering environmental sustainability consistent with our dedication to being carbon impartial by 2030.”

Designing efficient LTNs
In Greenwich, LTNs work by dividing residential areas up into zones – automobiles are restricted from crossing between zones from 7am to 10am and 3pm to 7pm, Monday to Friday. The zones can nonetheless be accessed from main roads, however the scheme is designed to cease drivers utilizing residential streets as quick cuts – an issue that has been on the rise with the widespread use of sat navs.
With a purpose to keep away from having bodily obstacles between zones, which have been cited as security considerations, proscribing entry for emergency automobiles, and might trigger inconvenience to native residents, drivers who violate these restrictions will face fines enforced by ALPR cameras.
With a purpose to achieve exemption from the scheme a particular N1 allow have to be used, which might solely be obtained for important companies, taxis, skilled carers and residents who’re registered as disabled (Blue Badge holders). Residents may also apply for a person circumstance exemption, nevertheless, there is no such thing as a automated exemption.
“We’re not focusing on native drivers for enjoyable. 40% of our residents don’t even personal a automobile, however areas comparable to East and West Greenwich are among the worst affected by congestion and air air pollution,” says Lekau.
The restrictions have been applied in response to considerations about site visitors congestion in residential areas and anti-social habits from motorists. Nonetheless, enforcement was initially delayed as signage was cited as deceptive, as a incapacity image was taken by some to imply automated exemptions for all Blue Badge holders, when actually solely allow holders have been exempt. These issues led to the beginning of the trial being postponed from November 2024 to January 2025.
The 18-month trial can be assessing claims from folks dwelling in close by Charlton, who say they’ve skilled elevated site visitors volumes on their residential streets, together with within the neighborhood of a major college.
Clear Air Neighbourhoods
On the opposite facet of South London, Hammersmith & Fulham Council can be aiming to cut back site visitors on residential streets, utilizing ALPR digicam enforcement to penalize non-residents who use roads as cut-throughs. Although the outcomes are much like the LTN scheme in Greenwich, the Southwest London scheme makes use of completely different laws and designates the enforced streets Clear Air Neighbourhoods (CANs), with a acknowledged major goal of lowering sickness and deaths from air pollution within the space.
Though the official major focus is to cut back air pollution, there are clear knock-on advantages for VRUs in lowering the variety of automobiles, with the council taking the chance to implement different measures to advertise energetic journey, these embrace enhanced pedestrian areas with anti-skid surfacing, new public seating and planters, extra cycle parking, and an investigation into upgrading pedestrian crossings.
The newest CAN trial started in October 2024 in Hammersmith to deal with growing congestion on Clancarty Street – a route getting used as a shortcut to entry the close by Wandsworth Bridge Street. The 18-month trial builds on the framework established in two different profitable trials within the space.
ALPR enforcement for the CANs is much less restrictive than Greenwich’s LTN – in Hammersmith all automobiles registered to addresses within the borough can go cameras with out penalty, with no particular allow wanted. Residents may also achieve momentary permits for guests utilizing the RingGo app and particular provisions exist for taxis, companies, and important companies. As with the LTN, entry remains to be doable to all streets utilizing designated routes.
The ANPR/ALPR expertise in Hammersmith is being offered by Videalert cameras. Based on the council documentation, these “ONVIF compliant HD cameras seize the very best high quality photographs to attenuate discard-rates, enhance productiveness and assist scale back the variety of appeals.”
The cameras hook up with a DfT Producer Licensed hosted platform which integrates with the council’s allow techniques to make sure that resident and permitted automobiles can go.
Based on council stories, CANs within the borough have achieved 15,000 fewer vehicles per day utilizing residential streets as cut-throughs, an estimated 1.9 tonnes discount in carbon emissions every day and an estimated 1.35kg discount in nitrogen oxide (NOx) every day.
These enhancements handle what the council describes as “the decades-old and seemingly unmanageable site visitors downside in South Fulham” which had “been made worse lately by elevated use of satnavs.”
The brand new schemes in South London, whether or not designated as Low Site visitors Neighbourhood or Clear Air Neighbourhoods, present how enforcement might help to make streets safer for VRUs, whereas additionally having extra advantages in lowering congestion and air pollution with the intention to shield native residents.
Past LTNs
LTNs alone aren’t sufficient to advertise energetic journey for longer journeys, that are prone to take residents out of the relative security of an LTN. To deal with this Greenwich is investing closely in biking infrastructure and promotion.
The South London borough has elevated its cycle community “fairly significantly,” based on Councillor Averil Lekau, cupboard lead for local weather motion, sustainability and transport, Greenwich Council, with new routes and “above London common cycle coaching funding.”
Sensible initiatives embrace free cycle coaching, a ‘strive earlier than you bike’ scheme run by Peddle My Wheels and expanded cycle parking choices. “We’ve dedicated to growing the supply of cycle parking within the borough and lowering ready lists for cycle hangars in our native implementation plan,” says Lekau.
Greenwich’s energetic journey imaginative and prescient additionally extends to public transportation, with the council working intently with Transport for London (TfL) on a number of initiatives to attach bicyclists with different modes. These embrace bus speedy transit connectivity, improved bus infrastructure, and city heart enhancements.
