Safety Considerations in Design
All roads open to traffic pose some degree of risk to their users. Road safety is therefore a relative measure and design choices may result in comparatively safer or less safe performance.

Synectics offers a range of design-related services for:

  • Pro-actively identifying opportunities for safety im provement at all stages of the design process;
  • Quantifying the safety implications of design choices;
  • Incorporating road user safety considerations in the design process, through risk assessment; and
  • Considering the safety effects of Value Engineering (VE) study recommendations.
     
 
 

Road Safety Audit (RSA)An RSA is a formal safety performance examination of an existing or future road or intersection by an independent audit team. As a proactive tool for identifying and documenting opportunities for safety improvement, an RSA may be applied at any time throughout the lifecycle of a roadway.

Example
Synectics staff developed RSA guidelines for the Federal Highway Administration (FHWA) in the United States, for use by State and local authorities and has led or conducted road safety audits throughout North America.
 

Safety Risk Analysis in Road Design Road designers work within an established range of design values to arrive at a result that best responds to all the ramifications of a project. In arriving at a balanced solution that satisfies competing operational, environmental and economic objectives, designers should also explicitly consider the likely safety outcomes of their choices.

Synectics uses state-of-the-art tools and methods, including safety performance functions (SPFs) and collision modification factors (CMFs) to quantitatively estimate the potential safety outcomes of design alternatives, in support of trade-offs between competing interests.

Safety Support in Value EngineeringVE or value analysis is a process involving the systematic application of analytical, creative and evaluation techniques to identify ways of achieving required functions in the most cost-effective manner.

Synectics provides expert support in quantifying the safety risks and benefits of VE alternatives. This ensures that costs or benefits linked to changes in relative safety performance are explicitly considered in the whole-life value of road designs.
