abstract="The paper involves a discussion of research into the use of a logit mathematical formulation to model modal split. The model investigates the extension to the multimodal situation in terms of both user and system variables. Time and cost difference are the major variables introduced for the systems; income, age, and a rush-hour dummy are other variables entered. The trip modeled is a short commuter trip, which is a part of a longer overall trip and involves the access to a commuter rail station only. The line-haul portion is not considered. The mathematical formulation is probabilistic in nature and can be used with any number of choices of mode. Four choices were available for the research data. Two methods of aggregating, summing probabilities or taking absolute choices, were discussed and tested. The value of time can be developed by the use of time and cost coefficients derived for the model. A value was found that was similar to some of the previous values but of lesser magnitude than values found for longer trips. The model coefficients themselves were derived by a computer program that employed a maximum likelihood technique to iterate to significant values.<p /><p>Language: en</p>",
