Transportation Modeling

Since the 1990s Kern COG has maintained a regional travel demand model and socio-economic forecast. The program uses data from local, state and federal surveys, a regional traffic count program and a regional land use model. To minimize duplication of effort, the Kern COG modeling program is guided by a memorandum of understanding among Kern COG’s member agencies. Modeling is performed as a service to those agencies, and to meet state/federal requirements. Contact Ed Flickinger for more information.
