Estimation of Origin-Destination Matrices Using Traffic Counts - A Literature Survey
Abstract
The Origin-Destination (OD) matrix is important in describing transportation in a region. This matrix has information on the travel and transportation made between different zones of a region. The OD matrix can be estimated using traffic counts on links in the transport network and other available information. This information on the travel is often contained in a "target OD matrix." The target OD matrix my be an old (probably outdated) matrix or a result from a sample survey. From these two data sources various approaches to estimating an OD matrix has been developed and tested. This survey provides a survey of generic approaches and an annotated bibliography of some individual contributions. Some models and methods are in another paper tested in medium sized applications in a congested region.
