1. Implementing SAFE Junctions for walkers and cyclists
without delaying drivers
or cyclists or walkers
LCC / JRG Oct’14

2. The Challenge
650 Londoners seriously injured / killed every year ... Most on Major roads ; Junctions
#1 hazard : Left Hooks
Cyclists (& peds) will bypass ‘facilities’ that delay
Despite this carnage, TFL have refused to do anything
(Jan’12) which might impact ‘capacity’ (motors)
Can we resolve this major problem ?
in various different situations

3. Non-Solutions at Major Junctions
Advanced Stop Lines
no use when lights are green
put cycles in position of max. risk
NB all fatal junctions have ASLs
‘Early Start’
confusing & misleading
only first 2 or 3 get across
tail and middle : same left hook risk
UNSAFE no matter how many secs start
... these are both false ‘facilities’
which do nothing for peds

4. Current Situation conflict between cyclists : left turning traffic
Green for left turns at same time as straight ahead traffic and straight head cycles (right turns may be held at red)
Only 1 (or 2) traffic lights
No cycle control
Clearly defined traffic lanes
Extra traffic lanes = speed
Rarely cycle lane into jct
(collisions still occur
with cycle lane/track)
Also risk of right hook from opposite direction
Poor / no ped. facilities
Long delays

5. RED for left and right turns GREEN for: drivers ahead cycles ahead
Proposed Phase 1 for Drivers, Cycles and Walkers (N-S) protected approach lanes for cycles
RED for left and right turns
GREEN for:
drivers ahead
cycles ahead
walkers cross in single phase
all same time
north & south-bound can GO at same time
then same applies E-W
LEFT HOOKS ELIMINATED

6. Requirements / Constraints
Early separation of lefts / aheads / rights...
Long queue-length approach lanes
Bus stop too close to jct >> move it
Cannot work on single lane roads
IF banned turns , 2 lanes enough
Cannot work on roundabouts
Cycle lane (track) may be RHS (or 2-way)
T-jcts easier than X-roads
No cycle only phases
No ped.only phases
Islands NOT needed
Lane discipline – for cyclists and drivers

7. Proposed Phase 2 for Turning Traffic
RED for Straight Ahead drive/cycle/walk
GREEN for :
N&S bound left turns
E&W bound rights
at the same time
Cycles: 2-phase right
as per Cph, Berlin,
and walkers…
Then same applies E-W
TFL Signals agree (May’13)
this is ‘’capacity neutral’’
NO IMPACT ON TRAFFIC FLOW

8. Detail of Cyclists Left / Right Turns
Left filter desirable(BJ)
before traffic-light
If enough space
Ped crossing may be informal
20% 60%
Cycles can often stop further forward than drivers ( no ‘confusion’ re which light )
2-Phase Right turn
All cyclists kerbside
No ASLs
20% 80%

9. (1) T-Junction e.g. Southwark Bridge(N) may be 4-way cycling & walking2 2 1 2 3 3 3 1 1
Early separation
Single exit lane only
Only 3 phases
as now 2 3

10. (2) Major Intersection e.g. Vauxhall ; Mile End3
Move bus stop to exit side
Bus stop too close ?
Single exit lane 4 1 2 1 3 4 1 3 2 2 3 1
Why have TFL taken a lane out at Mile End ? 4 3 1 1 2 4 3
Only 4 phases
as now
n.b. 1 size does not fit all

11. BUT Several CSH jcts have 2 minor arms
i.e. not enough lanes to separate all 3 flows
Sometimes we can ban turns = less lanes
– but some roads are just too narrow...

12. (3) Primary:Secondary X-roads e.g. CS2 ; Ludgate Circus
AHEAD ONLY
Single exit lane 3 1 3 1 2 1 4 4 1 3
Assumption that cycle light on minor roads = extra phases is wrong 1 2 1 2
Single exit lane 3
AHEAD ONLY
Long N-S ahead phase (1)
ONLY 4 PHASES
Secondary roads can have (protected) cycle lanes & cycle-lights

13. Implementation Options all arms not always possible / necessary phasing is different for each option
Not minor : minor junctions
Major T junctions [ 3-way
Major : Major cross-roads [ 4-way
Major : Minor cross-roads [ or T-jcts
Not Roundabouts – but
applicable when rdbt removed
Works equally well with 2-way tracks
1-way systems or contraflows
also prevents #2 shunts and #3 right hooks

14. Way Forward Identify 5 or 6 viable prototype sites
Can-do approach to design / imp.
NB Modelling not required
Implement – within < 6 months
Monitor impact on traffic & safety
