Description: Legacy Route ID from CANSYS or legacy system reference. This data is used for Conflating Pavement Management data for 0.1 mile Pavement distress data (ev_HPMSPavementCondition) because Pavement management data collection still refers to State Highway System by Legacy RouteId.Example: KHubRouteId: 02310007000 was LegacyCRND 023I0007000-EB in CANSYS.Also, KHub routeId is determined based on how vehicle traverse the roadway along ramps at intercahnge loactions(whereas in Cansys, the routes could terminate at the middle of a bridge). KHub Routes follow divided highway geometry where applicable. This has caused some differences in mileage and alignment changes when compared to systems that still use the concept of how routes were identified in CANSYS
