IIIIIII ���� <br />Ferri rriIIINe )(err rI nw:N4 ety AnallOysis <br />To quantify the reduction in crashes for each concept, the CMF Clearinghouse website was used. The <br />Clearinghouse website provides crash modification factors (C1\1Fs) for various countermeasures <br />implemented on a segment or at an intersection. Using the Clearinghouse, C1\1Fs were selected based <br />on the relevance of the countermeasure to the concept analyzed. The C1\1Fs used for the various <br />improvement concepts are shown in Table 10 through Table 13. <br />Table tun gut Crash IiiIriicatiIFaclrs <br />CM F <br />0.57 0.62. <br />C�.1..!
