ESTIMATION OF AN ORIGIN-DESTINATION TRIP TABLE BASED ON OBSERVED LINK VOLUMES AND TURNING MOVEMENTS. VOLUME 1: TECHNICAL REPORT
The LINKOD modelling system estimates a trip table based on observed link volumes and turning movements. This trip table can be used as an input to traffic assignment and/or simulation models. LINKOD is designed for small area analysis where all link volumes are known. The system is driven by the models: SMALD, a trip distribution model for small areas, and ODLINK, an adaptable trip table assignment model. SMALD estimates a trip table (the Target table) based on trip rates at sources and sinks, and the network's service level. The ODLINK model corrects an input (Target) trip tables, so it best replicates the observed flows, when assigned using equilibrium assignment. The models are driven by the LINKOD software package. The package includes several computer programs which perform input data editing and extensive summaries of the results.
