Interactive digital map shows road collision history across London

London’s first interactive digital collision map has been launched by the Mayor and 1466 Transport for London (TFL) as part of a continued drive to improve road safety awareness to reduce the number of casualties in the capital.

The London Collision Map uses extensive data, collected by the police and held by TfL, to shine a light on road collisions in local areas. This creates a useful new way to inform road users about junctions with high collision histories and aiding improvement work in line with TfL’s commitment to improve transparency for customers and stakeholders.

The map allows anyone to easily search for collisions anywhere within London, providing information about when, where and how severe incidents were, which date back to 2005. The aim is to help raise awareness of road conditions and encourage road users to take extra care at junctions.

It comes as the Mayor and TfL publish their Annual Road Safety report, which highlights the safety performance and improvements that have been made on the Capital’s roads in the last 12 months. During 2014, the number of people killed or seriously injured (KSI) fell to its lowest level since records began.

The report also outlines the Mayor’s new target, set earlier this year, to halve the number of KSIs by 2020 compared to the Government base line – meaning a reduction of more than 14,000 deaths or serious injuries over the life of London's road safety plan to 2020.

TfL already uses collision data to identify areas where additional road safety improvements are required and works closely with the police to increase the amount of data it has access to. By combining it with traffic flow data, traffic counts and bus information, they are able to identify locations where more targeted enforcement and additional engagement with local communities can be made to improve safety.

The collision data is made available to the public with provisional collision data updated at regular intervals throughout the year. In the coming months, an application programme interface (API) will be released to enable software developers to create applications that will help drive further improvements in road safety.

Academics, researchers and TfL will also be able to blend the data with other sources to look for wider, long-term trends across London and the South East. Further changes to the TfL webpage are also planned in the future to help all Londoners make the best use of this data.

    TfL challenges app designers to make the most of cycling data
    Transport for London (TfL) has challenged app designers to improve their services to cyclists after expanding the data it makes available to them. TfL has added mapping information for eight Cycle Superhighways and one Quietway to their open data portal, allowing developers to make it even easier for Londoners to find and use the best cycle routes. New Superhighways and Quietways will be added as they open. The information allows developers to accurately map out the existing network within apps and on

    Collision data collection system set to rollout across UK
    A new system which collects data on road traffic collisions from police forces is set to be implemented across England and Wales. Collision Recording And Sharing (CRASH) has been built for the Home Office and Department for Transport (DfT) by systems integrator IPL. The platform will help pinpoint accident ‘black-spots’ to enable the DfT, Highways England and local authorities to work together to make safety improvements to the road network. All English and Welsh police forces are expected to be feeding

    TRL: Cities must do more to help VRUs
    UK cities must learn from the Netherlands and Denmark if active travel and increased safety for vulnerable road users are to co-exist, says TRL’s Marcus Jones Active travel’ refers to modes of transport in which physical effort is required to undertake purposeful journeys - for example, walking or cycling to school, work or the local shops, as well as walking and standing as part of accessing public transport. The benefits of replacing short car journeys with more active forms of transport are obvious. Act

    Support for speed cameras remains high – but some drivers need convincing
    A national survey by the Institute of Advanced Motorists (IAM) has shown that although most drivers support speed cameras there are big variations across the country – and Londoners and people in the north-east appear to show higher levels of resistance than most. The survey polled 1,000 drivers of all age groups across Britain and asked “It is now common for the authorities to use speed cameras at the side of the road to identify vehicles involved in speeding offences. How acceptable do you think this i
