Crash Modeling For Urban Roundabouts:
A Case Study
Author(s)
O. Giuffrè & A. Granà
Abstract
In many cities and towns, a large number of intersections are considered sites
with promise for safety and operational improvements. Several studies have been
carried out in many countries to establish relationships between crashes and flow
and non-flow explanatory variables, using statistical tools to investigate factors
critical to road safety. Starting from a brief review of existing information and
analysis on the issue, this article summarizes the findings of an exploratory
analysis aimed at modeling injury crashes for a sample of urban roundabouts.
The methodological path followed in this research allowed to handle issues
associated with the estimation of a safety performance function, and also
introduce concerns related to the crash model transferability. At last, results can
supply methodological insights that may be useful in the subsequent quantifying
of benefits obtainable by engineering measures aimed at enhancing traffic safety
in built up areas.
Keywords: road safety, crash, roundabout, flow-only models.
