107 C h a p t e r 7 A corridor study, by definition, goes beyond the single-facility focus of a typical HCM2010 facility analysis. The purpose of a corridor study is to assess the ability of a subsystem of interrelated facilities to achieve a set of transportation performance objectives.

108 highly unlikely combinations may be included by random chance; therefore, multiple runs of the method may be needed to establish a representative travel time distribution. Importantly, the two methods have no direct link.

109 facility cause regular traffic diversion to the other facility, resulting in problems on the other facility. Treating the source cause of unreliability can result in reliability improvements on both facilities.
