Planning for ‘Vision Zero’ with London Borough of Southwark

Planning for ‘Vision Zero’ with London Borough of Southwark

We are assisting the London Borough of Southwark (LBS) as they plan for new and challenging London-wide casualty reduction targets set out in the Mayor’s Transport Strategy under the banner ‘Vision Zero’. The main targets are summarised as:

  • To reduce the number of people killed or seriously injured (KSI) by 65% compared with 2005-2009 levels by the year 2022
  • To reduce the number of people KSI in/by buses to zero by the year 2030
  • To reduce the number of people KSI by 70% compared with 2010-2014 levels by the year 2030
  • To reduce the number of people KSI to zero on London’s roads by the year 2041


There is a particular emphasis within the strategy on reducing risk to vulnerable road users such as pedestrians, cyclists and motorcyclists. This complements the overarching transport objective of reducing car use (and vehicle emissions) within London by creating safe, attractive streets and places for healthy, clean modes.

As part of this work we have utilised our experience of analysing casualty data along with GIS capabilities to produce 3D visualisations of the data that provide an easily interpretable picture of ‘hot spot’ areas on the network. The visualisations can be viewed here ( and they allow the user to navigate around the whole LBS network.

Mapping the network in detail, along with information on traffic flows and highway assets (bus stops, crossings etc), also allowed a statistical modelling exercise to be undertaken to see whether a more targeted approach to ‘hot spot’ identification, considerate of underlying traffic/layout factors, could be achieved.

In addition, a new, simple way for assessing the casualty numbers against metrics such as modal share or population data was proposed to highlight relative ‘risk levels’ for different types of road users.

LBS have been very keen for us to try and utilise new and innovative approaches to the data in light of the bold targets being set for casualty reduction in the coming years.
