This study sought to make up for a shortcoming of the fixed parameter model that constrained the estimated parameters to be fixed across observations, by applying random parameters that can take into account unobserved heterogeneity. Three variables had a random parameter among nine significant variables in segments with lighting systems, while seven of the eleven significant variables in a segment without a lighting system had random parameters. The different influence of interstate highway geometrics on vehicle crashes with and without lighting systems found through this study considering unobserved heterogeneity may hopefully help reduce accident frequencies and consider installation of lighting systems on interstate highways in the future.<br /> <br /> Document type: Article<br /> <br /> == Full document ==<br /> &lt;pdf&gt;Media:Draft_Content_846260205-beopen262-6744-document.pdf&lt;/pdf&gt;<br /> <br /> <br /> == Original document ==<br /> <br /> The different versions of the original document can be found in:<br /> <br /> * [http://downloads.hindawi.com/journals/jat/2017/4740532.pdf http://downloads.hindawi.com/journals/jat/2017/4740532.pdf] under the license https://creativecommons.org/licenses/by<br /> <br /> * [http://dx.doi.org/10.1155/2017/4740532 http://dx.doi.org/10.1155/2017/4740532] under the license cc-by<br /> <br /> * [http://downloads.hindawi.com/journals/jat/2017/4740532.pdf http://downloads.hindawi.com/journals/jat/2017/4740532.pdf],<br /> : [http://downloads.hindawi.com/journals/jat/2017/4740532.xml http://downloads.hindawi.com/journals/jat/2017/4740532.xml],<br /> : [http://dx.doi.org/10.1155/2017/4740532 http://dx.doi.org/10.1155/2017/4740532]<br /> <br /> * [http://downloads.hindawi.com/journals/jat/2017/4740532.pdf http://downloads.hindawi.com/journals/jat/2017/4740532.pdf],<br /> : [https://www.hindawi.com/journals/jat/2017/4740532 https://www.hindawi.com/journals/jat/2017/4740532],<br /> : [https://core.ac.uk/display/88193485 https://core.ac.uk/display/88193485],<br /> : [https://academic.microsoft.com/#/detail/2598844815 https://academic.microsoft.com/#/detail/2598844815] under the license http://creativecommons.org/licenses/by/4.0/<br /> <br /> * [http://dx.doi.org/10.1155/2017/4740532 http://dx.doi.org/10.1155/2017/4740532],<br /> : [https://doaj.org/toc/0197-6729 https://doaj.org/toc/0197-6729],<br /> : [https://doaj.org/toc/2042-3195 https://doaj.org/toc/2042-3195]</div>
