Temporal and spatial equilibrium of flow on networks

Humanities & Social Sciences Communications
Knowing the temporal and spatial equilibrium (TSE) flow is the basis for transportation planning and management of each mode (ocean, air, rail, road, logistics, etc.). It also helps to alleviate congestion of each mode on a transportation network.
