Illegal parking of delivery trucks used for pickup and delivery (PUD) reduces traffic capacity and causes delays. A geographically based combinatorial model was developed to estimate the extent of capacity losses and subsequent delays. The model uses a geographically based inference
engine to extract data from several large-scale databases and process the data. These data are presented and compared with data from other temporary loss-of-capacity events. Because only weekday and daytime activities were studied, the resulting estimate of the national PUD effect is somewhat conservative.
