Traffic & accident data collection in Tyne & Wear

What is TADU?

The Tyne and Wear Road Traffic and Accident Data Unit or “TADU” plays a key role to support the delivery of transport solutions and economic development across Tyne and Wear. TADU is jointly funded by the 5 Tyne and Wear districts and manages two key data sets:

  • Road traffic accident data in Tyne and Wear and Northumberland.
  • Traffic flow data in Tyne and Wear.

TADU maintains the database of road traffic accident information on behalf of the Tyne and Wear districts (CIRTAS). It also meets the statutory requirement for the provision of road traffic accident data to the Department for Transport on behalf of Tyne & Wear and Northumberland authorities. TADU is responsible for the collection and management of traffic and cycle flow data from an extensive network of automatic traffic count sites that it manages in Tyne and Wear (TRADS).

More recently TADU has expanded to host traffic and accident data for a number of regional authorities on the relevant databases including the fire and rescue services, local councils and the police force.
The North East Regional Road Safety Resource is a sister organisation to TADU, and is also based at Gateshead Council, but is funded by the region’s three road safety partnerships. The Resource provides information and data analysis to support road safety education, training and publicity work (ETP) in the North East region of England.

This is primarily done at a regional level, using a combined collision and casualty statistics database provided by the region’s three police forces, and working with groups such as Road Safety GB North East.  Work is also undertaken at a sub-regional and local level with the members of the three road safety partnerships, which includes the police, the fire and rescue services, and the individual road safety and engineering teams in each of the region’s local authorities.

The Resource’s website provides several useful tools for road safety ETP work, including an extensive library of research reports produced by the Resource, data tables for quickly referencing road safety statistics, a calendar of what activities, campaigns and events are taking place in the region, and an interactive casualty map of the North East that gives information on every casualty on the region’s roads that was recorded by the police for the past three years.  The website address is

The data

What is the data used for?

The data we host provides input into a wide range of areas including the following:

  • Development and implementation of the Local Transport Plan  
  • Strategic transport planning and modelling  
  • Road safety campaigns and schemes  
  • Transport schemes including road and public transport improvements  
  • Managing congestion  
  • Enhancement of provision for cyclists  
  • Planning and development control  
  • Environmental planning and control Monitoring the progress of the above

TADU works in close cooperation with a range of organisations. In addition to the five Tyne and Wear local authorities these include:

  • Department for Transport  
  • Police Forces for the North East Region  
  • Fire and Rescue Services for Tyne and Wear, Durham and Darlington  
  • Highways England, Durham, Darlington & Cleveland Councils  
  • University and the research community Developers submitting planning applications

TADU Traffic Volumes Dashboards and Plans

TADU produces two annual publications which are available on the Gateshead Council website.

The TADU Annual Accident Report provides a summary of road traffic accident and casualty statistics for Tyne & Wear for the last 5 years. The report provides a reference to the baseline year (the 2005-2009 average), to which the Tyne & Wear Integrated Transport Authority (TWITA) set targets for the reduction of road traffic casualties.

The report is published by TADU on behalf of the Tyne and Wear Districts to comply with the statutory duties given to the Highway Authorities under the Road Traffic Act 1988, Section 39. Data for the period 1974–2010 is available from TADU upon request.

The Annual Traffic Flow Report provides an overview of traffic flow by direction of travel, along main corridors and routes across Tyne and Wear. Information is provided for the previous 5 years at each site were available. The appendix gives a full site summary for all the sites TADU holds information on; this includes annual average flows broken down into months days and hours. Some of the Data we hold is obtained through the Highways Agency.

Traffic Volumes Plan

The Tyne and Wear Traffic and Accident Data Unit (TADU) and Gateshead Council’s Geospatial Systems (GIS) Team have developed an interactive map showing the locations of all of the locations where Automatic Traffic Counter (ATC) data is collected within the Tyne and Wear area.

The data for this map is taken from the Traffic Information Database (TRADS), which is maintained by TADU and contains up to date information on all traffic and cycle counters in Tyne and Wear. The data plotted represents the total traffic volume at the site for the selected year, and the size and colour of the point is dependent on the traffic volume at the site.


Once a class and year has been selected, the data is displayed on the map; each of the points displays the 7 day Average Daily Traffic (ADT), the point when selected displays a small summary box containing the details of the traffic volume. This box contains the data for each site for a 6 year period plus the data available for the current year (where data is available), the 7 day Average Daily Traffic (ADT), the 5 day Average Weekday Traffic (AWT), the Average Weekend Traffic (W/E) and the Number of days where volumes were collected within the each year (DAYS). On the Cycle Volumes display, if a site contains less than 150 days of data then the colour is masked to Grey as we feel that this data may not be totally representative.


This information on and within the map is given on the distinct understanding that Gateshead Council does not warrant the accuracy of the information and on the basis that neither the Council nor any officer, servant or agent of the Council is legally responsible either in contract or in tort for any inaccuracy, errors or omissions herein contained whether arising from inadvertence or negligence or from any other cause whatsoever.

Traffic Flows Data

The Tyne and Wear Traffic and Accident Data Unit (TADU in partnership with the Northumbria Safer Roads Initiative (NSRI) and Gateshead Council’s Geospatial Systems (GIS) Team have developed an interactive map showing the locations and summary details for all traffic speed surveys that have been carried out across the Northumbria Police Force Area over the past year.


The map itself shows all the locations around Northumbria where there has been a speed survey conducted within the last year.  Zooming in on any speed survey location on the map then displays the average speed recorded in both directions at each site (this can be toggled to show the 85th percentile speed by using the radio buttons at the bottom left hand side of the map screen).  Finally, clicking on any speed survey point gives more detailed information for that site:  Road name, direction of travel, average daily vehicle numbers, average speed, 85th percentile speed, and the start and end date of the survey.

The majority of this data is sourced from TADU and NSRI’s network of around 580 automatic traffic counters around Northumbria police force area, and is supplemented by the temporary speed survey data that is provided by individual local authorities, this data is published in the document library of the North East Regional Road Safety Resource website (  It is our intention to eventually display a rolling three years’ worth of speed data on this map, but at the moment we are only displaying data from January 2015 onwards.
