Based on the SPFs, Crash Modification Factors (CMFs) were developed for selected design elements. For the validation of developed SPFs and CMFs, the frequency of traffic crash estimated using the SPFs and CMFs was compared with the actual frequency of traffic crashes. As a result, traffic ...

4) Use residual plots to assess the confidence in and form of the SPFs at varying traffic volume; and 5) Coordinate with HSM research being performed by Southeastern Transportation Center (STC) universities to maximize regional approach to development of SPFs and Crash Modification Factors (CMFs)...
Functional form Misspecification Highway safety 摘要 This study further examined the use of regression models for developing crash modification factors (CMFs), specifically focusing on the misspecification in the link function. The primary objectives were to validate the accuracy of CMFs derived from th...
The objective of this study was to develop crash modification factors (CMFs) and estimate the average crash costs applicable to a wide range of road-barrier scenarios that involved three types of road barriers (concrete barriers, W-beam guardrails, and high-tension cable barriers) to produce a...
Exploration and comparison of crash modification factors for multiple treatments on rural multilane roadways As multiple treatments (or countermeasures) are simultaneously applied to roadways, there is a need to assess their combined safety effects. Due to a lack ... J Park,M Abdel-Aty,C Lee - ...
