Transportation Planning and Demand Modelling

Fratar Method = Determines future travel patterns between zones based on present travel patterns and growth factors Gravity Model = Predicts the percentage of individuals who will choose one mode over the other Poisson Regression = Estimates trip production per zone based on high correlation between variables Mode Choice Behavior = Influenced by trip purpose, socioeconomic characteristics, and transportation system characteristics

Traffic Assignment = To assess deficiencies in the existing transportation network Trip Distribution = To determine the number of trips originating in the study zone and their trip destinations Mode Choice Analysis = To evaluate the effects of limited improvements and expansions to the existing transportation system Route Assignment = To provide design hour volumes and turning movements

Gravity Model = Produces trip tables or O-D matrix Poisson Regression = Used for estimating trip production per zone Fratar Method = An iterative process to determine future travel patterns Mode Choice Behavior = Influenced by socioeconomic characteristics of trip makers

<p>Temporal aggregation = Trips are aggregated temporally, and trip generation models seek to predict the number of trips per hour or per day. Segmentation of trips by type = Different types of trips have different characteristics that make them more or less likely to be taken at various times of the day. Aggregation of decision-making units = Predicting trip generation behavior is simplified by considering the trip generation behavior of a household as opposed to the behavior of individual travelers. Trip rates from National/Local Studies = Predicting trip generation behavior based on national or local studies.</p> Signup and view all the answers
