The iROADS® Risk Toolkit helps identify, assess and prioritise risks and then manage follow up activities and to co-ordinate an economical application of resources to assess and mitigate the likelihood and/or impact of an event. The Risk Toolkit can be used for any asset where risk policy and procedures have been produced, including:
- Vehicle Restraint Systems (VRS)
Originally developed for analysing the skidding risk using SCRIM or Grip Tester data the Risk Toolkit has been further enhanced to allow any asset to be analysed for any type of risk using a user-definable risk matrix. It incorporates a transparent and effective management system and utilises relevant data available within most highway networks to prioritise assets. It produces a risk Score for the asset and allocates actions from a set of user-defined with defined responses. It justifies work being carried OR not carried out to paymasters/management and it results in efficiencies in:
- Personnel time preparing information
- Personnel visiting sites to check data
The iROADS Risk Toolkit can be used as a standalone application or alongside other i-Roads modules for risk analysis of any asset. It assists in the identification, assessment, and prioritisation of risks and then allows for the management of follow up activities i.e. coordinating an economical application of resources to assess and mitigate the likelihood and/or impact of an event. The process, using the Risk Toolkit is typically as follows:
- Identify and characterise threats
- Assess the vulnerability of critical assets to specific threats
- Determine the risk (i.e. the expected likelihood and consequences of specific types of attacks on specific assets)
- Identify ways to reduce those risks
- Prioritise risk reduction measures based on a strategy
The Risk Tookit allows asset managers to demonstrate that a robust, auditable process is in place for assessing data and prioritising works on the basis of risk, and to demonstrate that a highway authority has taken reasonable precautions in the event of a claim.
The Risk Toolkit can be used for any of the assets where a risk policy and procedures have been produced, including:
- Vehicle Restraint Systems (VRS)
- Utilities etc.
Using the Risk Toolkit for Skid Resistance Policy Management
The Risk Toolkit utilises the following attributes as standard for Skid Policy Management, these are all user definable and subject to availability and recommendations from the business/stakeholders. The listed attributes below are weighted within the prioritisation model.
- No of Accidents
- Speed Limit
- Road Class
- Traffic Flow etc.
In accordance with best practice and the “Well Maintained Highways” document, the iROADS Risk Toolkit utilises a risk matrix for risk assessment. It considers all attributes and the likelihood of the hazard occurring using traffic volumes. This is an important added factor as it ensures that sites with more traffic are considered ahead of those with similar consequences and low traffic volume.
The Risk Toolkit can also suggest required treatments based upon where the scheme lies within the matrix and can support value management for scheme prioritisation. Deficient sites can be exported into a shape file which can then be displayed using a mapping system.
The Risk Toolkits is extensively configurable, allowing for each user’s specific asset register, risk matrix, processes and service levels to be applied.
Skid Investigatory Levels can be loaded via UKPMS HMDIF or CSV file and can be maintained interactively using the Risk Toolkit. Skid Investigatory Levels can also be added, deleted and modified across the network and an audit trail of change history recorded automatically.
In cases where the user has no reliable Investigatory Levels for loading, iROADS can generate an initial or proposed set by utilising the gradient and curvature data supplied with Scanner Surveys. These initial figures and categories can then be added to and modified interactively. Once the user is satisfied with the Investigatory Level definitions across the network, the data can be exported in HMDIF format for loading into a UKPMS compliant system.
