... 3 Introduction Purpose of the Guidance Intersection sight distance (ISD) is a key design element at intersections.
From page 4...
... 4 Guidance for evaluating the Safety Impacts of Intersection Sight Distance • Example applications of the content of this guidance, and • Other countermeasures and resources. The final chapter provides the base equations from the research.
From page 5...
... Introduction 5 This guidance can be used to inform decision making that is part of the following activities: • Conducting performance-based planning and design, • Making Highway Safety Improvement Program project selections, • Performing traditional and systemic road safety management, and • Implementing recommendations stemming from road safety audits. Additionally, it can be used as part of alternatives analysis when considering multiple options for treatment (e.g., informing an economic analysis of tree removal versus implementing geometric changes)
From page 6...
... 6 Guidance for evaluating the Safety Impacts of Intersection Sight Distance is illustrated in Figure 1. The Green Book includes a detailed discussion of how the minimum design ISD for an approach is determined (AASHTO 2011)
From page 7...
... Introduction 7 The CMFs in this guidance are applied to target crashes. Target crashes are defined as crashes involving a vehicle from the major road colliding with a vehicle entering from a minor road.
