4. Wrap-up

London’s Recovery Challenge

• We need to run public transport at much lower levels of capacity to support social distancing

• Travel by car has become more attractive as Londoners avoid public transport. Traffic levels similar to pre-lockdown now

• A car-based recovery has significant risks:• Congestion• Worse air quality• Poor economic recovery

• These risks have serious implications for public health

• Streetspace helps answer these risks

4

Funding and guidance

• £55m for Streetspace:• £45m to London’s boroughs for local

schemes• £1 0m to TLRN• Further £20m from DfT Emergency

Active Travel Fund

• For transformative schemes

• Government continues to demonstrate support for walking and cycling

5

CS7 Overview

• CS7 follows the Northern Line from Colliers Wood to Elephant & Castle and is a key part of our Bike Tube plan

• There were 324,000 trips each day at stations between Colliers Wood and Elephant & Castle (LUL 201 9). A proportion of these will need switching modes due to social distancing measures

• The corridor is also important bus corridor• Key objectives for the CS7 temporary scheme:

• Provide a safe and attractive cycling experience for diverse target audience

• Deliver quick, easy and low-cost temporary changes

• Minimise adverse impacts on buses• Provide targeted footway widening at

hotspots

Considerations throughout design process

• Many banned turns proposed are due to existing issues with collisions (particularly around Tooting Bec Station) as well as risks to cycles from left turning vehicles

• Equality Impact Assessment has been completed for the scheme. This will continually be reviewed throughout the construction and development of the scheme. It has been to Independent Disability Advisory Group for comment

• Construction is due to occur during night time hours. This is to reduce impact on traffic during the day, as well as the impact on bus services which people need during the day

• Loading bays have tried to be relocated as close as possible to businesses. Many of these locations are on side roads due to constraints with carriageway widths. Any businesses who still have issues with loading should contact TfL at streetspacelondon@tfl.gov.uk.

CS7 Balham station to Ritherdon Road Existing:• Bus lane northbound leading to Balham Station (Mon-Fri, 7am-7pm)• 2 lanes of traffic in each direction• Cycles using painted traffic lane

Proposed:• 2m wide with-flow temporary protected cycle tracks• Existing northbound bus lane approaching Balham station maintained

and extended. Changed to 24hr• New 24hr southbound bus lane approaching Ritherdon Rd• New bus pre-signal to provide 'virtual bus lane' for southern section• Ritherdon Rd junction and Balham Stn Rd provided banned l-turns

except cycles and buses (to provide cycle protection and bus priority)• Banned l-turn into Balham Park Rd and Chestnut Gr. Balham Park Rd to

reduce l-hook risk and rat-running peak traffic. Chestnut Gr is to be able to accommodate wider footways to enable social distancing.

• Removing/reallocating parking to widen pavements to aid social distancing

10

CS7 Ritherdon Road to Tooting Bec station

Existing:• Bus lane southbound, 7-1 0am,

4pm-7pm• Mandatory cycle lane

approaching Ritherdon Rd but otherwise in traffic lane northbound

Proposed:• Removal of bus lane

southbound 7-1 0am, 4pm-7pm

• 2m wide with flow temporary protected cycle tracks

11

1 . The new bus gate allows buses to avoid queues onthe approach to Ritherdon Road. It is unlikely the queue of traffic will block this access.

2. There may be some delays in this section as buses are mixed with general traffic, we will use signal strategies to mitigate this as much as possible.

3. This section is expected to have a neutral impact due to limited changes and the junction currently operates with spare capacity.

4. Buses are protected by the bus lane, but if there is queuing this could become blocked. We will work to mitigate this with signal timing strategies, there may be less green time for the side road access.

Balham to Tooting Bec – Network Impact Assessment

12

Tooting Bec to Tooting Broadway

Existing:• Advisory cycle lanes in off peak parking area• Significant no. of side roads with A24 access• SB bus lane between Totterdown Rd to

Iceland (7-1 0am, 4-7pm)

Proposed:• Remove parking & relocate loading

and disabled bays to red route returns• 24/7 retained bus lanes where possible,

1 50m increase in bus lanes• Improved junctions for cycling and buses• Reduced side road access to and from A24• Tooting Bec Road / Upper Tooting Road

temporary junction layout

13

1 .Neutral impact. There may be some delays caused by buses stopping at bus stops in the live traffic lane. Banned turns improve throughflow of traffic and reduce friction.

2.Neutral impact. There may be some delays caused by buses stopping at bus stops in the live traffic lane. Banned turns improve throughflow of traffic and reduce friction.

3. This is the most impactful section, this junction is over capacity already and the loss of the lane will cause some delays to buses and general traffic

4. Neutral impact at the Tooting Broadway junction due to no significant changes.

Tooting Bec to Tooting Broadway - Network Impact Assessment

14

Tooting Broadway to Colliers Wood

Existing:• Colliers Wood to Longley Road – no bus priority and

advisory cycle lanes• Longley Road to Tooting Broadway - sections of bus

lanes northbound and southbound 7-1 0am, 4-7pm, and advisory cycling lanes

Proposed:• Colliers Wood to Longley Road - protected cycle

lanes• Longley Road to Tooting Broadway:

• Protected cycle lanes• 24/7 retained bus lanes (increase of 9m)• Bus priority at Longley Road junction• "Hold the left" protection for cycles at j/w Priory

Rd/Merton High St• Improved junctions for cycling and buses• Reduce left hook risk

15 Tooting Broadway to Colliers Wood- Network Impact Assessment

1 .Neutral impact. There may be some delays caused by buses stopping at bus stops in the live traffic lane. Banned turns improve throughflow of traffic and reduce friction.

2.Neutral impact. There may be some delays caused by buses stopping at bus stops in the live traffic lane. Banned turns improve throughflow of traffic and reduce friction.

3. This is the most impactful section, due to the mix of turning and straight ahead traffic there will be some delays to buses and general traffic.

4. At this junction, there will be a neutral impact in the AM peak, but in the PM peak there will be some delays caused by the new separately signalled cycle facility. Some of these delays may be mitigated through signal timing changes.

Rd

Approved section

Colliers Wood to

Balham

Balham to

Alderbrook Rd

This 700m section connects Balham Station with Cycleway 5 (from Clapham Common to Waterloo) via Alderbrook Road.

This would create a 1 .3km section of Cycleway (including the low-traffic streets to Clapham Common) from Balham station to C5.

ExistingThis section is relatively narrow, with one traffic lane in each direction (and no bus lanes in either direction).

Balham to

Alderbrook Rd

Proposal on A24:• With-flow protected cycle lanes (with

temporary materials)• Banned left turn except

buses/cycles into Balham Station Rd• Banned right turn into Bedford Hill• Banned left turn into Dinsmore Road• Remove parking and relocate loading

to accommodate cycle lanes• Retaining bus stops at the same

locations with one new bus stop bypass

Proposal on C5 link:• Make Alderbrook Road exit only (to

reduce traffic flows)

18

Engagement and consultation approach

• Streetspace schemes implemented on temporary basis

• Engagement post-delivery, rather than before

• Explain decision-making• Engage with diverse communities• Invite feedback• Show how feedback has influenced

our decision and made changes• Build on Londoners' changing mindset

and want for 'new normal’• Formal consultation if we want

to make schemes permanent

19

• Feedback from TfL and Sustrans website, shared with project team

• Engagement with key strategic stakeholders

• Localised tailored engagement – both virtual and socially distant

• Advocacy from local people and groups

• Asking Londoners:

• What do you like?

• What don’t you like?

• What’s your experience?

• How could it be improved?

• Make permanent?

What do the next few months look like?

20

• Streetspace schemes will be monitored to assess the impact on:

• Road danger and KSIs

• Traffic movement

• The number of people cycling

• Access and inclusion for older and disabled people, and other protected groups

• Bus journey times

• Mystery shopper surveys

• These may not apply to all schemes

• Data will be used to help improve temporary schemes and to inform decisions over whether they will be made permanent
