This study is a methodological framework for evaluating the operating and pricing policies in an intermodal auto-rail network. Commuters departing from their homes access their final destination, a Central Business District (CBD), via auto, rail, and intermodal auto-to-rail modes (e.g., park and ride). If a commuter chooses to begin the trip by auto, there are numerous paths to reach the final destination. Once on the highway, the commuter can switch to rail at stations along the rail route. The commuter may also choose to walk to the rail station closest to the trip's origin. The intermodal network is considered as one system, and traffic flows and travel costs are optimized for the whole system and not for separate auto and transit networks, as is the case in most previous studies. The central part of the framework is an equilibrium demand-supply model that consists of a mode choice and a traffic assignment submodel. The commuters' choice of using auto or rail is represented by a mode choice submodel. The traffic assignment submodel assigns transit (walk-to-rail and drive-to-rail) and pure auto trips to routes in the network, based on the minimization of an individual traveler's generalized (travel time and out-of-pocket) cost. The model yields modal shares, equilibrium flow pattern, and resulting generalized costs of the network assignment. The framework is applied to an intermodal network, modeled closely after a northern New Jersey commuter corridor, and used to analyze policies that include increasing parking capacity on commuter rail lots, increasing tolls on highways, increasing the parking fee at the CBD, decreasing rail fares, and improving rail service quality. These policies are evaluated based on user costs, and transit and highway operators' costs and revenues.
