MAST Online is an innovative and award-winning web based data analysis tool for road safety professionals to gain insight crashes and the people involved with them. This information is invaluable for planning effective and efficient interventions.

Where does the information come from?

MAST Online draws data from two main sources. Firstly, it contains Road Crash and Casualty information for the whole nation supplied by the Department for Transport. Secondly, it contains socio-demographic insights into the communities most at risk of becoming involved in crashes using Mosaic Public Sector.

What does MAST do with it?

The MAST Project Team use the raw data to create ‘data cubes’, a data storage technique used to process information into a convenient format for easy analysis. This is done using Microsoft SQL Server Analysis Services. These data cubes form the data source for users to generate reports.

How do users get at the data?

MAST Online allows users to create their own reports, simply be specifying what information the wish to look at and how they wish to categorise it. Results are displayed instantly in both chart and number grid formats, which can be freely saved and downloaded for further use as required. The screenshots on our Samples page will provide some idea of what a MAST report looks like, and how flexible and easy it is to use.

How do I become a user?

Any organisation with an interest in road safety can access MAST Online, simply by becoming a member of MAST. If you are interested, please complete this form.

How will users be supported?

Online help has been provided in the form of Wiki pages explaining the concepts behind MAST and the techniques used to make the most of it. The MAST User Forum also provides help and advice to MAST users. Training courses are also available.

What are the different versions of MAST?


Provides essential analytical resources for road safety professionals. Developed from complete STATS19 dataset used to produce Reported Road Casualties Great Britain, it also offers unique insight into people involved in crashes with the help of Mosaic Public Sector, the market leading socio-demographic database from Experian.

MAST Professional

Gives public sector road safety stakeholders complete access to STATS19 contributory factor information for analysis. With over two hundred specially designed additional dimensions, users can create flexible and insightful reports involving CF data in any required permutation. In order to support best practice, MAST Professional does not include all crashes reported under STATS19: only police attended crashes since 2006 with at least one recorded CF are included.

MAST Scotland

Provides road safety stakeholders with complete access to the dataset which underlies the most recently published version of Road Casualties Scotland. Road safety is a devolved matter, and the Scottish Government permits STATS19 records to be amended retrospectively. Consequently, information published in Scotland differs slightly from that held by the Department for Transport for inclusion in Reported Road Casualties Great Britain.

MAST Provisional (coming soon)

Affords all MAST members access to the interim dataset which lies behind half yearly road casualties estimates produced by the Department for Transport. The estimates are produced using an algorithm which approximates final expected figures based on historical trends, and therefore they are not identical to MAST Provisional. Due to the incomplete nature of this data, some MAST dimensions are unavailable in MAST Provisional.

MAST OpenData (coming soon)

Provides straightforward access to essential road safety statistics, based exclusively on the subset of STATS19 data made available on the data.gov.uk website. It is primarily intended for use by schools and colleges, and similar public education purposes.
