Transportation forecasting
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. Traffic forecasting begins with the collection of data on current traffic. This traffic data is combined with other known data, such as population, employment, trip rates, travel costs, etc.
Trip generation
Trip generation is the first step in the conventional four-step transportation forecasting process used for forecasting travel demands. It predicts the number of trips originating in or destined for a particular traffic analysis zone (TAZ). Trip generation analysis focuses on residences and residential trip generation is thought of as a function of the social and economic attributes of households. At the level of the traffic analysis zone, residential land uses "produce" or generate trips.
Trip distribution
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. This step matches tripmakers’ origins and destinations to develop a “trip table”, a matrix that displays the number of trips going from each origin to each destination. Historically, this component has been the least developed component of the transportation planning model.
Route assignment
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 of trip distribution provides origin-destination trip tables. Mode choice analysis tells which travelers will use which mode.
Transport en commun

Le transport en commun ou transport public est un mode de transport consistant à transporter plusieurs personnes ensemble sur un même trajet. Il est généralement accessible en contrepartie d'un titre de transport comme un billet, un ticket ou une carte. Néanmoins il peut être mis à disposition du public à titre gracieux dans certaines circonstances (pic de pollution par exemple).
Ingénierie des transports

L'ingénierie des transports est l'application de principes technologiques et scientifiques à la planification, la conception, l'exploitation et la gestion des installations destinés aux moyens de transport afin de garantir la sécurité, l'efficacité, la rapidité, le confort, la commodité du transport de personnes et de marchandises. Parmi les sous-disciplines de l'ingénierie des transports on peut citer l'ingénierie ferroviaire et l'ingénierie marine.
Land transport
Land transport is the transport or movement of people, animals or goods from one location to another location on land. The two main forms of land transport can be considered to be rail transport and road transport. Several systems of land transport have been devised, from the most basic system of humans carrying things from place to sophisticated networks of ground-based transportation utilising different types of vehicles and infrastructure.
