While median width plays a large role in the occurrence of these crashes, increased width alone does not eliminate them and quite often, the median must be shielded with a barrier. Cable barriers provide a cost-effective solution to the shielding issue. </p><p>The system is more forgiving than traditional concrete <a href="/wiki/Jersey_barrier" title="Jersey barrier">(Jersey)</a> barriers or steel barriers used today and remains effective when installed on sloping terrain.

However, a study of motorcyclist injury rates for several types of highway barrier did not find an appreciable difference in fatal and severe injuries between cable and W-beam barriers. Both were significantly more hazardous than concrete barriers but less hazardous than none.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Types">Types</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cable_barrier&action=edit&section=1" title="Edit section: Types"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>There are two types of cable barrier systems in use today, low-tension and high-tension.

This system is also called the “generic” system, referring to the fact that it is not exclusively manufactured by any single producer. </p><p>Low tension simply means the cables themselves are tensed only enough to eliminate sag between posts. Large <a href="/wiki/Spring_(device)" title="Spring (device)">springs</a> at both ends of the cable run are compressed (according to temperature)<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> to maintain the tension in the system. </p><p>When a vehicle impacts the low-tension system under normal conditions, the cable moves as much as 12 ft (3.7 metres) from its original location. This movement is known as the dynamic deflection. Given the lack of tension in the system, individual installations, or “runs”, of cable are limited to 2,000 ft (600 metres) with an anchor assembly at each end. </p><p>Due to the low tension of the system, the cables tend to lie on the ground in the event that an impact damages multiple posts. As such, there is no residual safety value within the undamaged remainder of the 2,000 ft (600 metres) installation and that entire section of barrier will remain nonfunctional until repaired. </p><p>Despite these perceived shortcomings, low-tension cable barrier, until recently, was arguably the <a href="/wiki/Workhorse" class="mw-redirect" title="Workhorse">workhorse</a> of the industry.

In most other aspects, the two systems are very different. </p><p>High-tension cable consists of three or four pre-stretched cables supported by weak posts. Currently, all high-tension systems are <a href="https://en.wiktionary.org/wiki/proprietary" class="extiw" title="wikt:proprietary">proprietary</a>, that is, marketed under exclusive right of a specific <a href="/wiki/Manufacturing" title="Manufacturing">manufacturer</a>. </p><p>During installation, the cables are placed on the posts, and then tightened to a specific tension according to <a href="/wiki/Temperature" title="Temperature">temperature</a>. The tensions values range between approximately 2,000 and 9,000lb (9,000 to 40,000 Newtons). Due to this tightening, the cable installations can be of indefinite length. In fact, the lengths of the runs are usually only limited by the presence of obstacles such as median openings or bridge columns. </p><p>When a vehicle impacts the high-tension system under normal conditions, the cable deflects as little as 8 ft (2.4 metres) from its original location. The inherent tension within the system also allows the cables to remain strung, even after an impact that removes several posts, thus allowing the remainder of the run to function normally. </p> <div class="mw-heading mw-heading2"><h2 id="Performance_limits">Performance limits</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cable_barrier&action=edit&section=4" title="Edit section: Performance limits"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Safety_testing">Safety testing</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cable_barrier&action=edit&section=5" title="Edit section: Safety testing"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A roadside safety hardware feature must undergo rigorous safety testing before it can be used on the <a href="/wiki/National_Highway_System_(United_States)" title="National Highway System (United States)">National Highway System (NHS)</a> in the United States.
