Collision investigation and prevention

Collision Investigation and Prevention (CIP) and what processes and policies are in place to support this.

1. Do you have a policy in place to support your approach to Collision Investigations and Prevention and the schemes you put forward for delivery?

No. The Devon County Council (DCC) Road Safety Strategy & Operational Plan is in draft form only. But DCC with other regional partners including Torbay Council, Plymouth City Council and Cornwall County Council have agreed and adopted a shared road safety strategy for the “South West Peninsula Road Safety Partnership” now called “Vision Zero South West”.

2. If the answer to Q1 is yes, can you please provide a copy of this policy? 

Refer to our response to Q1

3. If the answer is no to Q1, do you plan to implement a policy in the near future? 


4. Do you undertake an annual collision review? 


5. If the answer to Q4 is yes, what criteria do you use to identify cluster sites or sites needing a safety scheme? 

Road and Transport website Cluster site methodology

6. Do you use any software to help assessment collisions and identify concern sites? If so, what software. 

Yes. Buchanon Computing AccsMap and Microsoft Power BI for additional data visualisation.

7. Do you use a risk based approach to CIP? If so, please provide the criteria you use. 


8. Do you use a GIS based system to map collisions or road characteristic to give roads a risk score or red, amber, green rating?

Yes, for A & B Class Roads

9. If you answered yes to question 8, can you provide the detail of how this risk score is achieved and confirm whether this information is publicly available via an online mapping system?

10. How many road safety schemes do you deliver on an annual basis? 

On average 1-5 per annum.  This can vary as it depends on the analysis of the previous five years injury collision data.

11. What is your annual budget for road safety schemes? 

The annual budget will vary depending on the analysis of the previous five years injury collision data and other non-road safety funding priorities.

The current approved 2-year capital programme for 2020/21-2021/22 incorporates £190,000 for 6 identified cluster site improvement schemes; £4,746,000 for two route-based schemes (including £3,746,000 from the Safer Roads Fund grant and £1,000,000 local funding).

For other road safety interventions, education, training, publicity activities and for supporting enforcement, the annual revenue budget is approximately £437,000.                        

12. How many potential schemes so you have for future deliver pending prioritisation or budget? 

Currently 82 cluster sites with 10 sites either delivered or in design.

13. What level of funding would be required for you to deliver all known pipeline or potential road safety schemes.

This information is not held by the Council.

14. Do you look for sites where there is a higher risk of collisions occurring based on the characteristics of the road or does your prioritisation focus on past collision numbers? 

The focus is on past collision numbers. But also, on the cost benefit of interventions and in taking a Safe Systems approach to the collisions.
