      Multimodal Dynamic Freight Load Balancing 

      Abadi, A.; Ioannou, Petros A.; Dessouky, M. M. (2016)
      The urban traffic network has temporal and spatial characteristics whose changing conditions have often unpredictable effects on the flow of loads that include passengers and freight. As a result, the current traffic network ...
