Archway gyratory traffic impacts

Closed 14 Dec 2014

Opened 3 Nov 2014


Pedestrians and environment

Lower Highgate Hill would be closed to general traffic, reducing the heavy trafficdominance adjacent to the town centre. It would also enable a new public space to be created incorporating seating and tree planting. The public space would also increase accessibility to the businesses currently in the centre of the gyratory as pedestrians would no longer need to cross a busy road outside Archway Station.

Cyclists would have access through the public square on a two-way track. The proposals would require the closure of Archway Close and relocation of the parking and loading bays; alternative locations are being investigated. Flower Mews would be realigned to exit on Tollhouse Way and the parking and loading would be retained here.

On Archway Road, the Despard Road subway would be closed and a new surface crossing would be installed. This would reduce subway-related crime and improve the environment for pedestrians at this location.

Pedestrian journey times show waiting and crossing times would not significantly increase, meanwhile conflicts between pedestrians and vehicles would reduce.

When travelling from Archway underground station to bus stop R pedestrians would experience an average saving of 29 seconds in the morning peak hours and an average increase of 12 seconds in the PM peak hours.


General traffic (excluding buses)

There would be some longer journeys for motor vehicles at the busiest times of day on this route. The traffic modelling analysis looks at journey times at the busiest hour in the morning and evening peaks.

Heading northbound from Holloway Road to Archway Road in the morning peak, average journey times would increase by 4 minutes and 57 seconds. The same journey in the evening peak would see an increase in journey time of 1 minute and 5 seconds.

General Traffic travelling on the A1 Southeast bound would experience longer journey times in both peak periods with a 52 seconds delay in the morning peak hour and a 1 minute and 21 seconds delay in the PM peak hour.

Journey times between St Johns Way and Junction Road would be quicker in the morning peak by 31 seconds in the south-west direction and 1 minute and 6 seconds quicker for traffic travelling in the north-east direction. A small increase of 47 seconds would be experienced by traffic travelling south-west in the evening, whilst traffic travelling north-east would experience a 50 seconds decrease in journey times.


Traffic modelling has been undertaken for the bus routes which go through the scheme area to understand the impact of the scheme on bus journeys. A sample of journey times have been shown that represent typical bus journeys through the junction. Of the 16 journeys shown, six would be quicker, by up to two minutes. Nine journeys would be slower by a minute or less and one would be slower by between one and two minutes.

Routes 43 and 263 which run through Highgate and Holloway would experience a decrease in journey time in the Northwest direction and an increase of up to a one minute in the Southeast direction.

Routes 210 and 41 which run between Archway and Crouch End would see journey times increase by up to one minute in the morning in both directions. In the evening journeys towards Archway would experience an increase of up to one minute and journeys from Archway to Crouch End would see a decrease of up to two minutes.

Route 134 runs between Junction Road and Highgate. Journeys towards Highgate would see a decrease in journey times of up to two minutes in the morning and up to one minute in the evening. Journeys towards Junction Road would experience an increase in journey times in the morning of up to two minutes and in the evening up to one minute.

Routes C11, W5 and 4 travel to and from Archway via Highgate Hill. Journeys towards Archway in the morning will see an increase of up to one minute and journeys from Archway will decrease by up to one minute in the morning and increase by up to a minute in the evening.


A sample of four journeys have been shown which cyclists may take in the proposed highway design. Cyclists travelling from the A1 Archway Road to Holloway Road would benefit from segregated cycle provision for the majority of the journey around the proposed highway layout. Journey time changes are expected to be negligible and cyclists will benefit from the significant increase in safe provision. An increase of one minute is experienced in the morning when travelling north-west and a decrease of one minute when travelling south-east. Evening journey times remain the same as present.

Explanatory note on accompanying traffic modelling data table

TfL has used traffic modelling techniques to calculate the expected journey time changes on certain routes through the scheme area at the busiest hour in both the morning and evening peak. This data table outlines the expected journey times through two modelled stages:

  • Current situation on street. Journey times for general traffic, buses and cyclists are taken from VISSIM models.
  • Future journey times with scheme – Expected on-street conditions if the Archway Gyratory scheme is built.


The data table includes information for sample routes for general traffic, buses, cyclists and pedestrians through the scheme area.

Complementary Measures

The impacts calculated through the traffic models do not take account of a range of additional complementary measures that would have beneficial impacts on journey times for buses and general traffic.

  • Road users can expect more comprehensive and specific travel advice to help them to make informed journey choices to avoid busy times and locations
  • We will continue our work with freight and servicing companies to support them to plan their activity to avoid the busiest times and locations, evaluate quieter technology to enable more deliveries to take place out of hours and investigate the benefits of consolidation centers
  • Through the creation of the new Roads and Transport Policing Command, we will target enforcement at the busiest locations and known hot spots to reduce hold-ups and delays and keep traffic moving
  • greatly increased enforcement against illegal parking and loading on these routes to keep unplanned disruption to a minimum
  • a behaviour change strategy (on these and other routes), which encourages drivers to use alternative forms of transport
