Streatham High Road St Leonards junction with Mitcham Lane and Tooting Bec Gardens relocated crossing

Closes 29 Oct 2017

Opened 18 Sep 2017

Overview

We have been working in partnership with Lambeth Council to deliver safety improvements at the St Leonard’s junction because its recent collision history ranks it as a priority for improvement.

Our plans aim to improve safety for all road users as we continue to work with Lambeth Council and the local community to develop further improvements along Streatham High Road.

We welcome comments and suggestions about our proposals. You can tell us here by Sunday 29 October 2017.

What we plan to do

For pedestrians

  • Relocate the controlled crossing at the junction. At the moment there is poor visibility between people using the southern unsignalised crossing and oncoming motorists. By relocating the signal-controlled crossing that is currently north of the junction to the proposed new location south where demand is higher, and by making it a straight-across signal-controlled crossing, we can make it safer for all road users. This relocated crossing would replace the existing unsignalised crossing on the southern arm and the crossing north of the junction where there is significantly lower demand

  • Create a raised  imprint block-paved effect crossing on Gleneldon Road indicating to drivers that pedestrians are likely to be crossing making it easier and safer for people approaching the relocated crossing.

For cyclists

  • Cycling would be permitted in the proposed bus lane on Tooting Bec Gardens (see below).

For bus passengers

  • Introduce a bus lane on Tooting Bec Gardens approaching the junction by removing some parking. 15 high-frequency bus routes pass through the junction. Delays resulting from the new crossing would be mitigated by a new 170 metre bus lane on Tooting Bec Gardens approaching the junction. There are often gaps in the parking so the proposal minimises the overall loss of parking spaces and makes more efficient use of the space (see the drawing for the location)
  • Ban the right-turn into and out of Shrubbery Road on Streatham High Road. Northbound buses are currently delayed by vehicles turning right into Shrubbery Road, approximately 150 metres north of the junction, because of a short right-turn pocket in the road. We therefore propose to ban the right-turn from Streatham High Road into Shrubbery Road for all traffic. There would also be a longer right-turn pocket to allow vehicles to queue without blocking traffic when turning into Sunnyhill Road. Vehicles turning right out of Shrubbery Road can also delay southbound traffic including buses so it is proposed that is banned too. The banned turns will only be implemented if needed. We would monitor congestion and bus delays to confirm if they are needed to mitigate the impact of the relocated crossing and making it controlled and will publish our findings
  • We would need to extend the right-turn ban from Mitcham Lane into Streatham High Road southbound to include buses. This wont have an impact on bus passengers as this turn is only used by buses 'not in service'. By fully banning the turn we reduce the traffic impact of the relocated crossing and making it controlled.

We would coordinate the crossing relocation with planned work to modernise the traffic signals with pedestrian countdown (telling you how long you have left to start to cross) and resurface the junction, which will save delays and disruption.

Our plans form part of the Mayor of London’s plan for Healthy Streets - a long-term vision to encourage more Londoners to walk, cycle and use public transport by making London’s streets healthier, safer and more welcoming. By providing more safer space we can encourage more people to use these healthy and sustainable forms of transport, whilst keeping other traffic moving. These improvements will contribute to Healthy Streets by:

  • Improving road safety, in particular for pedestrians and cyclists
  • Encouraging more people to walk
  • Improving the public realm and contributing to the wider regeneration of the area
  • Maintaining reliable bus services.

We will monitor the impacts of the relocated crossing and will continue to work with Lambeth Council and the local community to develop further improvements along Streatham High Road.

We aim to start work on the junction by January 2018 for completion by spring 2018.

Please give us your comments about our proposals for the junction and suggestions for other changes we might consider by 29 October 2017.

Why We Are Consulting

This section of the A23 along Streatham High Road is heavily congested and constrained by narrow roads and pavements and the confluence of the A23, A214 and the A216 Mitcham Lane. It is a busy bus corridor and a vibrant local high street. These proposals would help to make it safer for all road users but particularly people using the high street.

Delays to bus journeys and general traffic would result from the proposed relocated crossing. Please click here (PDF) to see our modelling of the possible impacts and below for an explanation.

We have used traffic modelling techniques to calculate the expected journey time changes through the area at the busiest hour in both the morning and evening peak. The journey time data table outlines the expected journey time impacts for general traffic, buses and pedestrians.

We expect the proposals will result in both positive and negative changes to journey times for drivers, bus passengers and cyclists if implemented.

Following implementation of the proposals if that was the outcome we would actively monitor traffic conditions on the roads to manage demand appropriately. We are investing in advanced traffic signal technology to allow us to better manage traffic depending on differing conditions at any given time, and we are working to improve road user information so people can make informed journey choices before they travel.

Buses

Traffic modelling has been undertaken for the bus routes which go through the junction to understand the potential impact of the proposals on bus journeys. The journey time impacts below relate to the section of the bus journeys through the junction only and not to the whole bus route.

From the data tables it can be seen the predicted change in journey times during the AM will fluctuate with increases and decreases by 1-2 minutes. Key exceptions to this are routes 249, 201, 333 and 57 which are all predicted to decrease -1 to -2 minutes northbound.

In the PM period again most routes are predicted to have journey time changes of up to a minute. Route 57 however is predicted to have a journey time decrease of -2 to -3 minutes northbound, and -1 to -2 minutes southbound. Additionally the route 201 journey time is predicted to decrease by -2 to -3 minutes northbound. The journey time for route 319 is predicted to increase by 2 to 3 minutes northbound. Finally, the route 333 is predicted to experience a journey time decrease of -1 to -2 minutes in both directions.

General traffic

We anticipate journey times for general traffic through the junction will fluctuate with increases and decreases by 1-2 minutes. There are some routes that are predicted to have more significant increased journey times such as those for vehicles along Tooting Bec Gardens.

In the AM period the journey time for general traffic is generally unaffected, with three routes predicted to experience an increase of up to one minute. The remaining routes experience a decrease in journey time, in particular Mitcham Lane to Streatham High Street of -3 to -4 minutes.

In the PM peak the journey time increases for most routes are predicted to be in the order of 1 to 2 minutes. Tooting Bec Gardens is predicted to have the greatest impact with an increase of 3 to 4 minutes. Again Mitcham Lane to Streatham High Street is predicted to decrease by -3 to -4 minutes.

Pedestrians

For pedestrians crossing on Mitcham lane, Tooting Bec Gardens and the Prentis Road pelican the waiting times are relatively unchanged with no noticeable difference to how it is now.

The maximum waiting time including the time to cross Streatham High Road on the south arm is predicted to be just over 2 minutes.

To mitigate the delays we are proposing to introduce a bus lane on Tooting Bec Gardens on the approach to the junction, meaning some parking will have to be removed. The right turns into and out of Shrubbery Road may also need to be banned to prevent vehicles waiting to cross the A23 and further holding-up traffic.

There are controlled crossings on the other major arms of the junction but not on the southern arm so people have to look for a gap in the traffic to cross the A23. Consideration was given to making the southern arm controlled and have an all-round green phase for pedestrians to cross but this was found to cause more congestion and long delays. There is a controlled crossing 100 metres to the north of the junction at Prentis Road which could be used in place of the one proposed to be relocated.
