Human Factors review of road traffic incident data

As part of Task 73 (Human Factors Integration) Highways England is funding a series of pilot studies designed to help identify the type of efficiencies and value that can be delivered on live schemes from performing human factors activities. The work documented in this report summarises a pilot study conducted over four weeks in January and February 2017 on the M5 J4a-6 Smart Motorway scheme and aims to address the following four objectives.
1. Incident data review.
2. Incident trending
3. Incident hotspot identification
4. Incident reduction options

Incident trend summary
With the caveat that traffic count data could not be obtained to normalise the data analysed, so the reasons for the findings require further consideration, the following key trends were observed for the years 2012 to 2016:
Incident counts in 2014 (with roadworks) were higher than in years without roadworks.  The same pattern is anticipated for the full years’ worth of data in 2016.
There are approximately four times as many incidents involving both a car and LGV in years with roadworks than years without roadworks.
There is more reporting of non-injury/fatality incidents in years when roadworks are insitu.
When roadworks are in-situ there is a large increase in the reporting of non-injury events; this is largely attributable to the construction site teams and CCTV
