The basic timetable based assignment problem is to find an optimal path for a passenger, given an origin node, a destination node, and departure or arrival time information. The deterministic transit assignment does not necessarily minimize the total elapsed travel time, but rather uses weight factors and non-time-based cost elements in determining the optimal path. Therefore, the algorithm tracks both time (to determine the feasibility of a path) and cost (to determine the attractiveness of a path).

STAN is an interactive-graphic system for national or regional strategic planning of multimode multiproduct transportation systems. Briefly described are the general concepts underlying the system, the data base structure, the assignment procedures, and the results. Data and results from an actual application are used to illustrate these concepts.

The multimodal equilibrium-equilibre multimodal (EMME/2) system is a multimode urban transportation planning method designed for interactive use. It is more comprehensive than other interactive graphic methods that have been developed to date. It has been developed on the Cyber 173 of the University of Montreal; however, it may easily be adapted for a certain class of micro (or mini) computers. In this paper we describe the general concepts that underlie the design of the EMME/2 system; the structure of its data base; and the possibilities offered by the network editor, the matrix editor, the function editor, the assignment processors, and the modules that produce the results.
