RAP Resources for RISM - iRAP

Supporting the implementation of RISM

Le libre méthodologie RAP outils and resources are evidence-based and designed to be integrated within agency road operations and investment planning, and support the implementation of the European Directive de gestion de la sécurité des infrastructures routières (DGSI).

How the RAP tools can be integrated in your agency

RAP tools and resources can be embedded in road policy, planning, design and operations to both proactively and reactively manage risk for pedestrians, bicyclists, motorcyclists and vehicle occupants.

Fit-for-purpose tools include:

Crash Risk Maps which use detailed crash data to capture the combined risk and safe system performance arising from the interaction of road users, vehicles and the road environment.
Évaluations par étoiles which are an objective evidence-based measure of the level of safety which is ‘built-in’ to the road infrastructure for all road users. They can be used with existing roads and new road designs. 5-Star roads have the lowest risk, and 1-Star roads have the highest risk.
Estimations des blessures graves et mortelles (FGM) which draw on Star Rating data, flow data for each road user and local network-level crash data to generate an estimation of FSIs on each segment of road.
Safer Roads Investment Plans (SRIP) which draw on data underpinning Star Ratings and FSI Estimates to identify cost-effective road improvements that can maximise the prevention of deaths and serious injuries. Agencies can also adapt investment plans to meet local needs and priorities.

Savais-tu ?

The Road Assessment Programme, RAP, began in Europe in 1999 as a partnership involving road authority and mobility club partners in Sweden, Spain, the Netherlands and UK.
The evidence-based free tools have now been used by development bank, road agency and NGO partners in over 100 countries with more than 3 million kilometres of motorways, primary roads, secondary roads, and urban roads assessed, and over €90 billion of agency investment made safer.
The Global Plan for the Decade of Action for Road Safety 2021- 2030 includes targets for 3-star and better roads and bringing 75% of travel to the same minimum safety standard for all road users.
Partners share knowledge and experience, and innovate for the mutual benefit of all. Partnerships include PHÉBÉ, SABRINA, SLAIN, RADAR et SENSoR. Global partnerships are supporting CycleRAP, AiRAP, Notation par étoiles pour les créations (NPE3C), Système de notation par étoiles pour les écoles (SR4S), la Youth Engagement App (YEA), Route Review Tool, and impact investment for safety.
Local leadership and ownership is encouraged in every country and region (e.g. EuroRAP, usRAP, AusRAP, ChinaRAP, BrazilRAP, IndiaRAP, ThaiRAP, MyRAP).
The Saving Lives Assessing and Improving TEN-T Road Network Safety Project (SLAIN) including countries such as Italie, Croatie, Grèce et Espagne provides evidence-based examples of how these techniques have been applied to understand and measure individual and collective network risk.

Stories of Success

How RAP tools and resources can support implementation of RISM

How RAP tools and resources can support RISM

There are several ways in which RAP tools and resources may be used to support the implementation of RISM. The SLAIN project, for example, showed how reactive Risk Mapping can be used to guide selective Star Ratings in order to prioritize a safety response.

The following table summarises how RAP tools and resources may be used to support specific articles of RISM.

RISM Directive Article/Paragraph	Description	iRAP tools and resources
*Art. 5*	*Network-wide road safety assessment*
5/2	Ability to evaluate accident and impact severity risk	Star Ratings and Risk Mapping may be used at the network level. A tool is under development to convert Star Ratings into NWRSA outputs.
5/2a	Involves visual examination, either on site or by electronic means, of the design characteristics of the road (in-built safety)	RAP Star Ratings involve visual assessment of the level of safety that is ‘built-in’ to roads.
5/3	Repeatability – enables periodic inspections and comparability of results	Star Ratings and Risk Mapping use a standardised methodologies that are used to track performance over time
5/6	Classification of all sections of the road network in no fewer than three categories according to their level of safety	Star Ratings and RIsk Mapping involves categorising road segments into one of 5 risk categories.
*Art. 6*	*Periodic road safety inspections*
6/1	Periodic road safety inspections are undertaken with sufficient frequency to safeguard adequate safety levels for the road infrastructure in question	Star Ratings and Risk Mapping may be performed periodically as part of performance tracking
*Art. 6a*	*Follow-up of procedures for roads in operation*
6a/1	Network-wide road safety assessments are followed up either by targeted road safety inspections or by direct remedial action	Fatality and Serious Injury (FSI) estimates and Safer Road Investment Plans (SRIP) may be used to assist in identifying and implementing priority countermeasures on priority road segments
6a/2	Indicative elements (Annex IIa) for targeted road safety inspections.	See table below
6a/3	Targeted road safety inspections shall be carried out by expert teams	RAP tools and resources are supported by Training and a network of Accredited suppliers and practitioners
6a/4	Findings of targeted road safety inspections are followed up by reasoned decisions determining if remedial action is necessary, and Identification of road sections where road infrastructure safety improvements are necessary and define actions to be prioritised for improving the safety of those road sections	Fatality and Serious Injury (FSI) estimates and Safer Road Investment Plans (SRIP) may be used to assist in identifying and implementing priority countermeasures on priority road segments
6a/5	Ensure remedial action is targeted primarily at road sections with low safety levels, and Which offer the opportunity for the implementation of measures with high potential for safety development and accident cost savings.	Fatality and Serious Injury (FSI) estimates and Safer Road Investment Plans (SRIP) may be used to assist in identifying and implementing priority countermeasures on priority road segments
6a/6	Prepare and regularly update a risk-based prioritised action plan to track the implementation of identified remedial action.	RAP assessments may be performed at periodic intervals
*Art. 6b*	*Protection of vulnerable road users*
6b	Needs of vulnerable road users are taken into account in the implementation of the procedures set out in Articles 3 to 6a.	Star Ratings, FSI estimations, SRIPs and Risk Mapping account for vulnerable road users, including pedestrians, bicyclists and motorcyclists.

Using proactive Star Ratings in conjunction with Road Safety Audits

RAP Star Ratings may be used in conjunction with Road Safety Audits to enhance safety outcomes. The Star Rating for Road Safety Audits (SR4RSA) manual provides practical examples for policy makers and practitioners. The following table summarises how Star Ratings align with the additional elements of Road Safety Audits listed in RISM Annex II.
