1. Analytical Support for Engineers
JtD Workshop February 2018

2. Overview
Consulted Senior Road Safety Engineer who made a number of suggestions.
Grouped into following categories:
Reports
Emerging trends
Communications
Route analysis and cluster analysis NOT covered here as these are core engineer tasks (in Essex at least!)

3. Reports All analytical reports “no matter how small”
Detailed analysis of user group/ area/ problem profile.
District profile summary, including emerging any trends and similar authority comparison.
Ad-hoc graphs & data briefings etc.
Done anyway
Add to distribution list
Unlikely to be too sensitive, but check GDPR/data sharing issues
Elicit useful feedback to make your own work better

4. When is a trend not a trend?
Emerging Trends
Spreadsheet showing month by month data for local authorities for changes in casualty types.
Observations from collision validation staff (e.g. noticing multiple collisions at a given location over a short period of time).
Initial notifications of a KSI from Police.
When is a trend not a trend?
Engineers want emerging trends
Sometimes we can be fooled by randomness (regression to mean)
Analyst should give context to trend to data to avoid wasteful knee-jerkery

5. Communications Overall headline figures (Power BI).
Validation backlog and understanding the data.
Help dealing with data requests.
“This is the most dangerous road in Britain, what are you going to do about it?” ~ compare national data for rates per vehicle mile by road type.
Co-location helps!
Help focus priorities to be data-led, not politically/who shouts loudest led
Routine updates help maintain dialogue and share knowledge
Easy to do in theory but easily forgotten so needs to become a habit

7. Small Changes Save Lives
SERP’s vision is to reduce death and serious injury due to road traffic collisions in Essex to zero. The partnership cannot do this alone, every road user plays a part in making sure that everyone gets home safely.  A small change in everyone’s road user behaviour could have a huge impact on casualty numbers.
