Route assignment, route choice, or traffic assignment concerns the selection of routes (alternatively called paths) between origins and destinations in transportation networks. It is the fourth step in the conventional transportation forecasting model, following trip generation, trip distribution, and mode choice. The zonal interchange analysis ...
A transport network, or transportation network, is a network or graph in geographic space, describing an infrastructure that permits and constrains movement or flow. [1] Examples include but are not limited to road networks , railways , air routes , pipelines , aqueducts , and power lines .
Transportation forecasting is the attempt of estimating the number of vehicles or people that will use a specific transportation facility in the future. For instance, a forecast may estimate the number of vehicles on a planned road or bridge, the ridership on a railway line, the number of passengers visiting an airport, or the number of ships calling on a seaport.
All trips have an origin and destination and these are considered at the trip distribution stage. Trip distribution (or destination choice or zonal interchange analysis) is the second component (after trip generation, but before mode choice and route assignment) in the traditional four-step transportation forecasting model.
Transport (in British English) or transportation (in American English) is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air , land ( rail and road ), water , cable , pipelines , and space .
Water transportation is the slowest form of transportation in the movement of goods and people. Strategic chokepoints around the world have continued to play significant roles in maritime industry. Although the slowest form of transportation compared to road and rail transport, it is the most cost effective. [citation needed]
Point-to-point (top) vs hub-and-spoke (bottom) networks. The hub-and-spoke model, as compared to the point-to-point model, requires fewer routes. For a network of n nodes, only n − 1 routes are necessary to connect all nodes so the upper bound is n − 1, and the complexity is O(n).
Transportation is a peer-reviewed academic journal of research in transportation, published by Springer Science+Business Media. The journal focuses on issues of relevance to the formulation of policy, the preparation and evaluation of plans, and the day-to-day operations management of transport systems. It concerns itself with the policies and ...
