NEAC

Acronym:

NEAC

Description:

NEAC can be used to analyse and forecast national and international transport flows. For forecasting transport flows, the model refers to the NEAC database that provides information on transport flows between regions. The underlying theory is that trade is the result of the specialisation of countries or regions. Besides the supply and demand factors (gravity model based on supply factors of the exporting country/region and the demand factors of the importing country/region) there is also a 'resistance' on the trade such as transport costs, imposed tariffs, and cultural differences. Also there can be favourable circumstances to trade within a group of countries due to the establishment of free-trade zones. A range of more specific NEAC models that can be coupled with the database has been developed. These include:
• a trade model for forecasting of future trade flows
• a modal-split model (estimation and forecasting of modal-split)
• an assignment model (assignment of traffic flows on transport networks)
• a container forecasting model (estimation of containerised transport)
• an environment model (calculation of emissions resulting from transport
• the EcoNEAC model (estimation of the effect of transport and infrastructure on the economy)
