Abstract
Purpose: To provide clues for enhancing multimodal transportation and trade policies, the transportation and machinery equipment trade and transportation trends for the 3 continents of Asia, Europe and Africa, AEA, were analyzed. Methodology: For the study area a multimodal network was defined. The relevant time-series information was extracted from centralized databases consisting of 4 categories: transportation and machinery equipment trade, transportation, geographical and socio-economic characteristics. The deployed techniques included: preliminary statistical analysis, regression and elasticity analyses, shortest path algorithm, gravity modeling and liner programming. Findings: The study identified possible relations between trade and transportation. Gravity modeling introduced GDP and transportation variables as the determinant factors for trade. The coefficients of gravity models often showed increasing time trends. The comparison between optimal trade distributions, based on linear programming, and their observed distributions, showed significant differences. Further study of the AEA trades can enhance trade routing and policy development. Limitations: The study database was limited to information accessible from centralized and international databanks. The trade information was aggregate at national and total transportation and machinery equipment level. The study AEA network was a simplified version of the actual multimodal network. Information about network actual link flows was not accessible. The origin and destination of trades were assumed to be the country’s capital. Originality/value: For the first time, trade and transportation trends for the 3 land connected continents of the AEA were analyzed based on a newly defined multimodal network.
