The report proposes a model based on the logit function to predict the rail and truck market share for specific city pairs and commodity groups. Effort was devoted to the problem of introducing both transport service variables and shipper's logistic variables into the model. The model was calibrated with data from the 1967 Census of Transportation and from various carriers. Significant regressions were obtained from linear logit models once the proper variables were identified. Theoretical monetary values of carriers' services were compared to the empirical values in the model, indicating that shippers pay more for quality service than predicted; this result may be due to bias in the model introduced by use of aggregated and unreliable data. It is concluded that further research using this model form with more disaggregate data could yield significant improvements in results and provide valuable information for public and private transportation planning.
