Scale and Scope of Safety Assessment Methods in the Project Development Process

LONG DESCRIPTION: PROBLEM OVERVIEW, SECTION 4.2

Safety Assessment Method: AADT-Only SPF

Project Phase: Preliminary & Final Design Project Type: 4R

Related Task: Safety Input for Value Engineering Assessment

Calculation Method:Hand Calculated

Comments: This example problem demonstrates how to consider the number of crashes as one input into the value engineering process. For this case, the problem evaluates three proposed roundabouts (four-leg, twocirculating lanes) that are located within the larger project boundaries.

Level of Analysis: Intermediate

Note: See table 3 for a full definition of Project Type designations.
