Junctions on the Camden Cycle Network

We have made a spreadsheet listing the junctions on Camden Cycle Network, classifying each one as Node,  Crossing or Terminus

Node: where two or more cycle routes meet at the junction e.g. at Royal College Street / Randolph Street the routes C6 and C50 meet

Crossing: where a single cycle route passes through a junction e.g. at Midland Road / Euston Road the route C6 crosses Euston Road

Terminus: where the end of a cycle route meets a major road without any cycling infrastructure e.g. Grays Inn Road route at High Holborn – only four of these so far

The cycle routes are named with their official names if they have them: C6, C27, C50, C41, C10, C52, LCN6 and Q1; otherwise they are named by the road they are associated with e.g. YorkWay, PoW (Prince of Wales Road), GoodsWay, Gower, GIR (Grays Inn Road), HHill (Chalk Farm Road and Haverstock Hill) etc.

Some very minor side road junctions in LTNs have been omitted. We have also included the Theobalds Road/Southampton Row junction although it’s not currently on a cycle route (it is on the planned route along Theobalds Road- Clerkenwell Road – Old Street, formerly called ‘Clerkenwell Boulevard’ and labelled Blvd here).

Each junction is represented by a pin on the map (blue for nodes (light blue when they have signals and dark blue for priority junctions),  green for crossings (light green when they have signals and dark green for priority junctions)  and red for a terminus) where

• the roll-over box contains the names of the roads at the junction – for crossings, the road containing the cycle route comes first, followed by the type of junction (node or crossing) and the route(s) passing through it e.g. C6 and C50 and then whether it has a signal or is a priority junction [the JAT diagram will clarify the layout]
• the pop-up box contains in addition the most recent date when work was completed and for signalised junctions,
  • a link to a JPG file containing a JAT for the junction (available for most of the signalised junctions on C6 e.g. Pancras Road/Midland Road; Judd-Tavi Place,  Sidmouth-Ampton, Agar Grove-Randolph-St Pancras Way and on C27 Tavistock Place/Marchmont Street); still working on the others;
  • a JAT or other score for the junction (we have allocated simple scores for the good crossings e.g. C6 over Camden Road and over Euston Road). Also a warning of ‘critical failures’ which are normally safety issues (e.g. turning right from Pancras Road at the Midland Road junction which has left hook risk); but this warning also applies to junctions where it isn’t legally possible to make a turning from one route into another (e.g. where C27 on Tavistock Place meets C6 on Judd Street where two right turns are forbidden);
• for priority junctions we plan to categorise solutions including blended junctions (with continuous cycleway), blue paint and when the cycle route crosses a major road the use of a parallel crossing.

The legend box currently lists most of the routes on the map, saying for each one, the number of junctions with signals and priority junctions. It might eventually contain an aggregate score.

See a larger view of the map. The details are in a Google Sheet which is here. For people who can’t access Google Sheets PDF here.

 Table showing the number of junctions where work was carried out each year

Note: some side roads where a continuous footway has been built have not been included in the study. The category ‘pre2012’ refers to work done on LCN routes from about 2007. The count for 2023 isn’t up to date: need to add Estelle Road, Mornington Crescent  and Healy St (both Tigers) as well as some blended junctions with continuous cycleway  (B St/Bedford, Daly/PoW, Crinan/Y Way). Also we only record the most recent date for each junction.

Number of junctions assessed so far = 23

• Judd Street/Tavistock Place isn’t technically a critical failure which is about safety but cycles can’t make the turns between the routes that meet there

Assessment of safety for cycling through a junction

Scoring in JAT

This will be based on the JAT (junction assessment tool) but modified to restrict the assessment to the effects on the cycle route at a crossing. e.g.

• at Midland Road / Euston Road, a signalised crossing, we will assess the safety of the two directions on the cycle route and a score out of 2+2 = 4 will be awarded (this evades thinking about moves between the C6 and Euston Road). A similar approach is used where C6 crosses Camden Road.
• But on more minor junctions which are crossings, we will simply assess all of the movements so as to allow for ease in joining a cycle route, e.g. at the Tavistock Place/Marchmont Street junction.
• at Royal College Street / Randolph Street (a priority T-junction node) each of the three arms is on a cycle route so a score out of 3 x (2 + 2) = 12 will be awarded
• at Tavistock Place / Judd Street – Hunter Street (a signalised crossroads node) each of the four arms is on a cycle route so a score out of 4 x (2+2+2) = 24 should be able to be awarded. But sadly, two right turns are banned so the score is out of 20.

Some initial Ideas on scores

A movement out from a signalised junction that

• is protected by a cycle stage in the signals with adequate following inter-green time to reach the destination arm scores 2. e.g.
• offers early release from a deep >= 5m ASL could get a score of 1 (orange) but if there are heavy left turn counts red (0) would be more appropriate,  similarly zero would be awarded where there are heavy right turns from the opposite arm. Note: develop the criteria as junctions are analysed.

Where a cycle route (running mainly through LTNs) crosses a major road that separates a pair of LTNs:

• a Tiger crossing  may be acceptable where traffic flows are below some level (to be decided) e.g.
  • where C6 crosses Mansfield Road. Traffic flows on Mansfield Road: 12,000 average 7-day daily (QC consultation report)
  • where Kings Boulevard crosses Goodsway.
• But providing only ‘Give Ways’ isn’t acceptable  except over very minor roads (which are unlikely to be LTN boundaries) e.g
  •  C6 crosses Calthorpe Street where the traffic flows are [Screenline C in 2016 7am – 7pm for Guilford Street (E Guilford Place) 11,103]

Where a cycle route (on a protected link) crosses minor side roads

• Blended junction e.g.
  • where PoW passes Harmood Street (blue paint) and Crogsland Road
• Route marked across the junction in various ways
  • where C6 passes Baynes Street the latter has ‘STOP’ but only zig-zag lines across the side road
  • where C6 passes Pratt Street there are logos and C6 across the side roads but rather weak lines
