All Site Information

This spreadsheet contains all information about the safety camera sites themselves, such as location, type of site, establishment date, and where applicable, decommissioning date.

s

Activation History

This spreadsheet summarises the number of times each safety camera has been activated by a vehicle each year from 2011 to 2016.  In most cases, these activations are progressed to offences (usually for exceeding the speed limit) upon investigation by the Fixed Penalty Unit.

s

Collision History

This spreadsheet summarises the number and severity of all road traffic collisions that have occurred within each safety camera site’s boundary from 1978 to 2015.

For most sites the boundary is approximately a one kilometre stretch of road (the exact measurements are included in the “All Site Information” spreadsheet), while for red light cameras it is a 50 metre radius around the camera itself.

“Fatal and Serious” is a collision in which at least one person was either killed or seriously injured.

s

Casualty History

This spreadsheet summarises the number and severity of all road user casualties that have occurred within each safety camera site’s boundary from 1978 to 2015.

For most sites the boundary is approximately a one kilometre stretch of road (the exact measurements are included in the “All Site Information” spreadsheet), while for red light cameras it is a 50 metre radius around the camera itself.

s

Average Hourly Speeds and Traffic Volumes

This spreadsheet summarises the data that the Northumbria Safer Roads Initiative holds on the traffic volumes and speeds at each safety camera site from 2007 to 2015.  In each case, the average is taken from all data that exists for each year, and is used to provide an average hourly figure.

Avg Hourly Traffic Volume – This is the average number of motor vehicles that pass through each site every hour.

Avg Mean Speed – This is the mean average speed of motor vehicles passing through each site.

Avg 85th Percentile Speed – This is the speed below which 85% of motor vehicles travelled through each site (this means that 15% of vehicles exceed this speed).

s

Speed Surveys

This spreadsheet summarises the data that NSRI holds on speed and traffic volume surveys carried out by local authority partners in the past year.

Speed surveys are generally undertaken by local authorities following queries or complaints from members of the public about excessive or illegal speeds on local roads.

NSRI uses this information to determine whether a section of road would qualify for safety camera enforcement as either a core or community speed concern site, and this recommendation is included in the final column.

The information given in this spreadsheet covers the average traffic volume, speed and 85th percentile speed recorded over the survey period.

s

Offences Other Than Speeding

This spreadsheet summarises the number of offences other than “exceeding the speed limit” that have been captured by NSRI’s mobile safety camera units.  These statistics began to be collected in their current form in August 2015, so data begins from this date.

Linking Road Casualty and Clinical Data to Assess the Effectiveness of Mobile Safety Enforcement Cameras: a Before and After Study

This paper was published in the British Medical Journal (BMJ) in November 2012.

The authors of the paper are Dr Neil Thorpe and Dr Lee Fawcett (both of Newcastle University).

The aim of the paper was to use Northumbria Police’s Stats 19 road user casualty data and Accident and Emergency in-patient information to estimate the impact of mobile safety cameras on the cost of treating individuals injured in road traffic collisions.

The version of the paper included on this site is the pre-print copy of the paper submitted to the BMJ that the authors retain copyright over.  For the published paper, please visit http://bmjopen.bmj.com/content/2/6/e001304.full

A Novel Approach to Collision Hotspot Identification Accounting for Regression to the Mean and Trend

This paper was produced for the annual Transport Practitioners’ Meeting in 2015.

The authors of the report are Dr Lee Fawcett, Dr Neil Thorpe, Joe Matthews, Fabio Galatioto (all from Newcastle University, Newcastle upon Tyne, UK), Karsten Kremer, Timo Hoffman, and Andre Muench (all from PTV Group, Karlsruhe, Germany).

The primary aim of this paper is to describe the development of a tool for assessing the likelihood of collisions occurring in the future at known road safety hotspots to enable a proactive, rather than reactive, approach to road safety scheme implementation.

Getting Value for Money from Investment in Road Safety: Are we Evaluating our Schemes Correctly?

This paper was produced for the annual Transport Practitioners’ Meeting in 2014.

The authors of the paper are Peter Slater (Data Analyst, North East Regional Road Safety Resource), Dr Neil Thorpe (Lecturer in Transport Studies, School of Civil Engineering and Geosciences, Newcastle University), Dr Lee Fawcett (Lecturer in Statistics) and Joe Matthews (both of the School of Mathematics and Statistics, Newcastle University).

It uses the Fully Bayesian approach to estimate the “Regression to Mean” effect on casualty reductions seen at mobile safety camera sites in Northumbria.

This allows a better estimate of the true value for money of installing these safety schemes, and the principles of the research can be used to evaluate future road safety schemes more effectively.

s

Evaluation of Mobile Camera Effectiveness

This report by the North East Regional Road Safety Resource is based on research commissioned by NSRI from the Resource and Newcastle University into the effectiveness of mobile safety cameras at reducing casualties.  This research excludes known effects such as the “regression towards the mean” to come to an objective and independent estimation of the number of casualties prevented by NSRI’s mobile safety camera programme.
