About This Camera

Camera Location & Hazard Overview

This camera covers the western approach to the Green Man Roundabout, the significant interchange at Leytonstone's northern edge named after the pub that still marks this end of the neighbourhood and remains a genuine reference point on road signs today.

Traffic Pattern & Congestion Trends

Heavy traffic converges here from several directions given the roundabout's role connecting multiple significant routes — one of the busier points on the whole A12 corridor through Waltham Forest at the standard 07:00–09:30 and 16:00–18:30 peaks.

Traffic Fines & Camera Enforcement

Given how complex this interchange is, wrong lane positioning on the approach is a genuine and common cause of minor hold-ups, alongside standard A12 speed limits and roundabout lane discipline enforcement. Anyone flagged here should search car park management early, since appeals move faster with the right reference to hand.

Road Closures & Alternative Routes

There's not much good alternative given the Green Man's role as a major interchange — most regulars simply factor in extra time approaching from this direction. If you break down mid-approach, providers you'll find by searching motorway breakdown service in this area typically reach you faster than inner London reputation would suggest.

Driver Safety & Local Tips

The Green Man Roundabout is one of relatively few junctions in this part of London where an old pub-derived place name has stuck as the official signposted reference point — the pub itself still stands, which isn't something you can say for most namesakes like it.

ULEZ & Emissions

The London Borough of Waltham Forest operates entirely within the expanded Ultra Low Emission Zone (ULEZ), active 24/7. Non-compliant vehicles face a £12.50 daily charge. No Congestion Charge applies in this borough. Check your vehicle compliance at tfl.gov.uk/ulez.

Parking near A12 GMT W Appr 3921J, North London

Street parking directly on the A12 here is impractical, so most people head into the Chingford and Walthamstow side streets instead. Those fall under Waltham Forest's CPZ, typically Monday to Friday 8.30am to 6.30pm, with MiPermit handling visitor sessions rather than paper permits now. The Ridgeway car park near Chingford Green and the side roads around Whipps Cross roundabout both offer a decent fallback. Double yellows are strictly enforced right up to the junction, so don't be tempted to squeeze in near the camera itself — patrols here are frequent.

If on-street parking is hard to find, apps like JustPark and YourParkingSpace let you pre-book a private driveway or car park nearby — typically from around £2–£6 per hour or £10–£25 per day depending on how central the location is.

Parking links are affiliate partnerships. JamCams may earn a commission at no extra cost to you.
