Old Street Roundabout Proposals - Impact on road users

Closed 11 Jan 2015

Opened 11 Nov 2014



Overall context

The improvements to Old Street Roundabout aim to reduce conflict between cyclists, motor vehicles and pedestrians and provide safer, more comfortable journeys.  We will close the north-west arm of the roundabout in order to make a new large public space.  Segregated cycle lanes will be introduced where possible and we will provide new surface-level crossings. We will also provide greater footway space and will remove obstructive street furniture wherever possible.

Old Street Roundabout is a key junction on the Inner Ring Road.  As a result, we need to ensure that our proposals continue to allow general traffic and buses to move smoothly through the area.  Our proposals would affect all road users to some degree – both positively and negatively.  This note explains what impact we expect our proposals to have and is accompanied by a more detailed table of data, which you can access here. This table shows expected changes in time for a range of journeys for general traffic, bus users, cyclists and pedestrians.

Pedestrians and environment

Closing the north-west arm of the roundabout to traffic would enable us to create a new public space, significantly improving the environment for pedestrians.  This new space would contain urban realm improvements such as seating, lighting and tree planting.  Providing new surface level crossings will increase the crossing choices for pedestrians and allow them to safely access the new public space.  We are also proposing to close the north-eastern subway, reducing the level of subway-related crime at this location.

Explanatory note on accompanying traffic modelling data table

TfL has used traffic modelling techniques to calculate the expected journey time changes through the scheme area at the busiest hour in both the morning and evening peak. This data table outlines the expected journey times through three modelled stages:

  • Base model (column A) – current situation on street. Journey times for general traffic and cyclists are taken from VISSIM models.
  • Future base model (column B) – Expected situation for general traffic in December 2016 if the Old Street scheme was not built, but taking account of the impact of all other TfL road schemes delivered by this date. Without the scheme, traffic signal timings in the scheme area would not change, so pedestrian wait times would remain as they are currently
  • Future journey times with scheme (column C) – Expected journey times in December 2016 if the Old Street scheme is built. These journey times take account of the advanced traffic signal management programme, which will change signal phasing to more effectively regulate the flow of traffic at certain locations to keep central London moving

The data table includes information for a sample of routes for general traffic, buses, cyclists and pedestrians through the area.

Further detailed modelling information is available on request by emailing your requirements and contact details to trafficmodelling@tfl.gov.uk.

Complementary Measures

The impacts calculated through the traffic models do not take account of a range of additional complementary measures that would have beneficial impacts on journey times for buses and general traffic.

  • Where there are negative impacts on journey times for bus routes shown in the table, a programme of work is being developed to save time elsewhere along the affected route by addressing delays and giving priority to buses at certain pinch-points
  • Road users can expect more comprehensive and specific travel advice to help them to make informed journey choices to avoid busy times and locations
  • We will continue our work with freight and servicing companies to support them to plan their activity to avoid the busiest times and locations, evaluate quieter technology to enable more deliveries to take place out of hours and investigate the benefits of consolidation centres
  • Through the creation of the new Roads and Transport Policing Command, we will target enforcement at the busiest locations and known hot spots to reduce hold-ups and delays and keep traffic moving
