Bus collision data

We publish two sets of data related to bus collisions and casualties.

IRIS is our incident management system, made up of bus incidents that are reported directly by bus operators. It covers all incidents, including 'damage only' (where the only damage which occurs is to the bus itself or surrounding objects). The data is published on the TfL website every quarter.

STATS19 is the national data set of road traffic collisions involving human death or personal injury. These occuron the public highway and are notified to the police within 30 days of the incident involving one or more vehicles.. We publish provisional data provided by the police on a quarterly basis. As final numbers of casualties and personal injuries can change (for example due to mistakes in recording or if someone is injured but later dies) we publish finalised annual data in June the following year, in line with national DfT statistics.

Bus collision investigations

Bus operators undertake their own investigations of road collisions, focusing on the root cause of the incident. This is different from police investigations, which seek to determine if a crime has been committed. We are planning to introduce independent investigation for the most serious incidents.

For major incidents, including fatalities and serious injuries, we gather relevant information from operators, police agencies, boroughs, coroners, the Driver and Vehicle Standards Agency and others. We review each incident regularly as part of our internal governance process, the Incident Review Group. The group has been set up to peer review the investigation of bus-related fatalities and other significant incidents. This ensures that immediate and root causes are identified, and the right action taken. We share key findings with stakeholders, including bus operators and make sure any actions required by us, the bus operator or other groups are allocated and completed.

Contract and performance management

London Buses use a range of data as part of the assessment of an operator's ability to provide a safe service. It is the responsibility of bus operators to manage the service their drivers deliver. Unsatisfactory performance can lead to the failure to win new contracts with us.

We are updating our bus contracting system to improve how we use road safety Key Performance Indicators (KPIs), and promote an even greater focus on safety. We are developing a safety scorecard which will combine all of our monitoring systems and KPIs. We will use this in our contracting and performance management with bus operators. The specific objective of the new proposals is to reduce the number of Killed or Seriously Injured (KSIs) on the London bus network in line with the Draft Mayor's Transport Strategy.

Vehicle design

As part of our bus safety programme we are developing a new safety standard for buses. This will identify a package of safety measures, including:

  • measures to prevent collisions such as autonomous emergency braking (AEB)
  • measures mitigate the impact of collisions such as the re-design of the front of bus

This will be developed and tested on London Buses throughout 2017 and incorporated into new buses being introduced to the fleet from end of 2018.

Incident support service

The incident support service is dedicated to assisting people affected by incidents where someone is killed or seriously injured. The incident support service will be the first point of contact for those affected, helping to solve practical problems resulting from the incident.

This can include:

  • short-term counselling services and the provision of transport (whether by air, road or rail) for family members of impacted individuals
  • short-term financial assistance in the aftermath of incidents such aspaying for travel and accommodation for family members who may live outside London and need to stay near a hospital, or replacing damaged items
  • assisting bereaved families in completing funeral arrangement

The incident support service will also provide ongoing support both during and following investigations. This includes making victims aware of relevant transport safety organisations and what support they offer, as well as letting them know about business partners and charities who provide professional specialist services.

Bus driver training and recruitment

As part of the Mayor's objectives to make London's streets safer, we have been working closely with London's bus operators to develop a new type of training for bus drivers. The training, called 'In the Zone', encourages greater awareness of the risks that we take when we're on the road, whether as a driver or a vulnerable road user such as a pedestrian, cyclist or motorcyclist. With this training, we encourage drivers to change how they assess risks, with the aim of reducing the number of incidents on London's roads.
