Stakeholders Benefits and Road Interventions Strategies


Roads (e.g. pavements, bridges and tunnels) deteriorate over timedue to environmental factors and use, and the required levels of services, in general, either increase or remain constant; the road sections must be maintained by executing interventions (e.g asphalt crack sealing of pavement, painting or replacing  the girders of a steel bridge).

There are an extensive number of possible intervention strategies (e.g. the types of interventions to be executed and the time of execution) that road agencies may use to ensure that roads continue to provide an adequate level of service

The SABARIS research project addresses the challenge of road agencies to select an intervention strategy for the road network that is optimal, taking into consideration the varying and conflicting values of road benefits for the stakeholders of this network. The objectives of SABARIS is to support this decision making by:

  • Identifying the Stakeholders
  • Determining the roads benefits for the stakeholders and way of engaging the stakeholders to determine these benefits and communicate to them that their concerns are being taken into consideration
  • Analysing the values of the benefits for the Stakeholders
  • Assessing the impact of the valuation of benefits on the optimatlity of intervention strategies for roads
  • Evaluating the sensitivity of the optimality of the intervention strategies due to variations in benefit values, especially when conflicting valuations between stakeholders exist.

 The SABARIS project will produce results that will be immediate use to infrastructure managers in European road agencies:

  • Classification of stakeholders in terms of road typer and road benefits
  • Ranking of benefits for different categories of road types according to stakeholders valuation
  • Stakeholder engagement strategies for different categories of road types
  • A prototype optimisation tool for the evaluation of intervention strategies that simultaneously takes into consideration the different valuations of Road benefits from multiple stakeholders
  • Guidelines for use and implementation of such an optimisation tool, in genral and for different road types, and for road agencies
  • Case studies illustrating and comparing the implementation, usage and outcome of the optimisation tool
