About This Camera

Camera Location & Hazard Overview

Traffic heading in all directions across North London converges on this roundabout, where Great Cambridge Road meets the A406 North Circular at one of the most significant junctions in this part of Enfield. It's the kind of junction that shows up in local traffic folklore, with almost every Enfield driver having a story about being stuck here at some point.

Traffic Pattern & Congestion Trends

Heavy traffic in all directions holds throughout the day, combining North Circular orbital flow with A10 traffic heading towards or from Hertfordshire, making this one of the busiest interchanges covered in this dataset. Friday evenings bring one of the sharpest peaks recorded anywhere in this dataset, as A10 getaway traffic overlaps with the standard North Circular evening rush. As with most junctions on this corridor, incidents nearby have an outsized effect on how this specific point behaves, and this roundabout's reputation as one of Enfield's busiest interchanges makes a road traffic accident claim solicitor a fairly common local need.

Traffic Fines & Camera Enforcement

Extensive ANPR and average speed camera coverage applies across this roundabout given its complexity and the volume of traffic changing between the North Circular and Great Cambridge Road here, among the busiest and most closely monitored junctions in the borough.

Road Closures & Alternative Routes

There is no simple alternative to this roundabout for A10/North Circular traffic; drivers with flexibility are better off timing their journey to avoid the standard 07:00-09:30 and 16:00-19:00 peaks. Experienced Enfield drivers generally accept there's no reliable shortcut here and instead focus on timing their journey to avoid the sharpest recorded peaks. As always, checking live conditions immediately before travelling is more reliable than assuming yesterday's pattern will repeat.

Driver Safety & Local Tips

It's one of the busiest and most complex junctions in Enfield — if you use it regularly, learning the lane layout in advance genuinely reduces delay for yourself and other drivers navigating the roundabout.

ULEZ & Emissions

Enfield has been fully inside the Ultra Low Emission Zone since its London-wide expansion in August 2023, with the charge operating 24/7 including bank holidays. Non-compliant vehicles pay £12.50 a day on top of any other charges. Check your vehicle at tfl.gov.uk/ulez before travelling through the borough.
