Book Description
The objective of this study was to evaluate the change in crash frequency or severity of varying lateral offset distances of high-tension cable median barriers in Minnesota. Crash and traffic data from 2016 to present were conjoined with roadway cross-sectional data and high-tension cable barrier locations to perform cross-sectional analyses for interstate segments equal to or greater than 0.05-miles long. Negative binomial regression models were estimated and used to develop crash modification factors (CMFs) for the following crash types: total crashes, target crashes, and barrier crashes. In addition to evaluating the impact of lateral offset, a naïve before-after evaluation was completed to quantify the impact of installing high-tension cable barrier.

Book Description
The Midwest Pooled Fund Program has been developing a prototype of a non-proprietary, high-tension, four-cable, median barrier for use anywhere in a 6H:1V median V-ditch. This system incorporates four evenly-spaced cables, Midwest Weak Posts (MWPs) spaced at 8 to 16 ft (2.4 to 4.9 m) intervals, and a bolted, tabbed bracket to attach the cables to each post. Full-scale crash testing was needed to evaluate the barrier's safety performance. According to the Manual for Assessing Safety Hardware 2016 (MASH 2016) testing matrix for cable barriers installed within a 6H:1V median V-ditch, a series of eight full-scale crash tests are required to evaluate the safety performance of a system. Previous full-scale tests conducted on this system have indicated potential cable snag on the cable bracket nuts and exposed threaded studs. Cable snagging can limit vertical cable movement and post deflection, which could then lead to significant occupant compartment deformation and penetration, and therefore failed tests. Consequently, new nut designs were investigated for use with the cable brackets in attempt to eliminate cable snagging. Tensile testing was performed on multiple sleeve nut prototypes and all were deemed acceptable.
