The Vehicle Routing Problem with Real-Time Travel Times
The paper considers a vehicle routing problem with time windows and real-time travel times. We assume the deployment of an information and communication system that is based on mobile technologies, which provides a real-time mobile connection between the dispatching centre and drivers, allows localising vehicles on road, and gives the online overview over traffic conditions. We explicitly incor...
متن کاملThe Special Application of Vehicle Routing Problem with Uncertainty Travel Times: Locomotive Routing Problem
This paper aims to study the locomotive routing problem (LRP) which is one of the most important problems in railroad scheduling in view of involving expensive assets and high cost of operating locomotives. This problem is assigning a fleet of locomotives to a network of trains to provide sufficient power to pull them from their origins to destinations by satisfying a rich set of operational con...
متن کاملVehicle routing with stochastic time-dependent travel times
Assigning and scheduling vehicle routes in a stochastic timedependent environment is a crucial management problem. The assumption that in a real-life environment everything goes according to an a priori determined static schedule is unrealistic. Our methodology builds on earlier work in which the traffic congestion is captured based on queueing theory in an analytical way and applied to the V R...
متن کاملStochastic Vehicle Routing with Random Travel Times
We consider stochastic vehicle routing problems on a network with random travel and service times. A fleet of one or more vehicles is available to be routed through the network to service each node. Two versions of the model are developed based on alternative objective functions. We provide bounds on optimal objective function values and conditions under which reductions to simpler models can b...
متن کاملAn Investigation of Travel Time Estimation Based on Point Sensors
Several transportation agencies are currently estimating freeway travel times using data provided by inductive loop detectors. These point detectors typically report only aggregated values of volume, lane occupancy, and time-mean-speed at relatively short polling intervals. Travel time estimation methods that assume speeds measured at points are representative of actual travel speeds over segme...
