Transportation service providers are pressurized to enable real-time logistics planning from a constantly changing demand. This paper focus on a real-time transportation service provider operating along a one-dimensional highway. Transportation assignments arrive following a Poisson process, and the transportation service provider is operating on this road system with a fleet of vehicles, trying to minimize the expected delivery time. Specifically, the optimal locations for idle vehicles, and the optimal locations for construction of distribution centers are considered. The strategies are evaluated with numerical simulations along a Swedish highway system.
