Implementing SAFE

Junctionsfor walkers and cyclists

without delaying drivers

or cyclists or walkers

LCC / JRG Oct’14

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

The Challenge650 Londoners seriously injured / killed every year ...

Most on Major roads ; Most @ 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

Current Situationconflict between cyclists : left turning traffic

Green for left turns at same time as straight ahead trafficand straight head cycles (right turns may be held at red)

Only 1 (or 2) traffic lights No cycle control

Clearly defined traffic lanesExtra traffic lanes = speed

Rarely cycle lane into jct(collisions still occurwith cycle lane/track)

Also risk of right hooks from opposite direction

Poor / no ped. facilitiesLong delays

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

LEFT HOOKS ELIMINATED then same applies E-W

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

Proposed Phase 2 for Turning Traffic

RED for Straight Ahead drive/cycle/walk

GREEN for : • N&S bound left turns • E&W bound rightsat the same time

Cycles: 2-stage rightas per Cph, Berlin,and walkers…

Then same applies E-W

NO IMPACT ON TRAFFIC FLOWTFL Signals agree (May’13)this is ‘’capacity neutral’’

Detail of Cyclists Left / Right Turns • Left filter desirable(BJ)

before traffic-light• If enough space • Ped crossing may be

informal

2-Stage Right turn All cyclists kerbside No ASLs

Cycle light forward

(1) T-Junction e.g. Southwark Bridge(N) may be 4-way cycling & walking

Early separation

Single exit lane only

Only 3 phasesas now

Notes on T-Junction Design Early separation of traffic ; lanes signed clearly & early

Islands / bollards / wands enforce ahead-only & turn-only Islands are NOT for pedestrians – just to separate streams Position of Cycle-light more important than height

1. E to W cycles GO ahead with E to W straight ahead traffic and W to E straight ahead traffic

(1) W to E cycles do not wait at (motor) t-lights but

give way / stop when peds. crossing

2. W to S cycles turn right with W to S right turning trafficand S to W left turning traffic

3. N to E cycles turn right with right turning N to E traffic and left turning E to N traffic

More ped. green time : cross in 1 phase, not 2 Same no. of t-light phases (3) as now

(2) Major Intersection e.g. Vauxhall ; Mile End

n.b. 1 size does not fit all

Notes on Major X-Roads Design Single lane (only) for straight ahead traffic – and exit Move centre-line to right; Less exit lanes needed 1(3) Ahead only & cycles & peds GO together [ Longer green 2(4) then Left (N&S) & Right (E&W) turners GO together Opposing (N&S) streams can GO together (then E&W) All cycles approach jct on Left Hand Side via... Protected cycle (only) lane into jct Cycle stop line / lights further forward [ No ASL box 2-stage right turn for cycles (as pedestrians) Bypass for left turning cycles (as pedestrians)

- but n.b give way to peds or Stop if Pelican present

More ped. green time : cross in 1 phase Same no. of t-light phases (4) as now

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...

(3) Primary:Secondary X-roads e.g. CS2 ; Ludgate Circus

AHEAD ONLY

Secondary roads can have (protected) cycle lanes & cycle-lights

AHEAD ONLY

ONLY 4 PHASES

Single exit lane

Long N-S ahead phase (1)

Notes on Primary / Secondary Design Light segregation on secondary [ armadillo Cyclists : 2-phase right turns : all 4 arms [ No ASLs 1. N&S ahead-only is dominant flow [ more green time2. N-bd Rights & Lefts GO together [ not as (2) above2. E-bd Cyclists GO ahead safely at same time 3. S-bd Right & Lefts GO together 3. W-bd Cyclists GO ahead safely at same time 2/3 E&W-bd Peds cross safely at same time 4. E&W traffic share same green phase– Ban Right turns out of secondary ?– Or just wait in middle (uncontrolled) More green time for peds & cycles to cross Same no.of phases as now (4)

Can also apply at T-junctions...

(4) Major:Minor T-Junction e.g. Harford St(CS2)

Long ahead only phase (1) Shorter turning phases (2,3)time-share withSingle phase pelicans and Cycles crossing N-S

2 lanes max N-S

1 wide exit lane

Notes on (narrower) 1-way streetnote: may also apply elsewhere if only 2 traffic lanes possible

N is No Entry for traffic and cycles

1. E to W cycles & peds and W to E cycles & peds can GO ahead with E to W straight ahead traffic and W to E ahead traffic as per normal (all turners held at red)

2. N to S cyclists can GO ahead at the same time as N to S traffic and N to W right turners (N to E left turns held at red)

3. N to E left turning traffic can GO with W to S right turners and E to S left turners (no conflict into wide 1-way)

More green time for peds to cross, safely

Only 3 t-light phases required

Implementation Optionsall arms not always possible / necessary

phasing is different for each option

• Not minor : minor junctionsMajor T junctions [ 3-way Major : Major cross-roads [ 4-wayMajor : Minor cross-roads [ 4-way • Not Roundabouts – but applicable when rdbt removedWorks equally well with 2-way tracks1-way systems or contraflows

also prevents #2 shunts and #3 right hooks

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 safety & traffic
