    摘要: A near real-time physical transportation network routing system comprising: a traffic simulation computing grid and a dynamic traffic routing service computing grid. The traffic simulator produces traffic network travel time predictions for a physical transportation network using a traffic simulation model and common input data. The physical transportation network is divided into a multiple sections. Each section has a primary zone and a buffer zone. The traffic simulation computing grid includes multiple of traffic simulation computing nodes. The common input data includes static network characteristics, an origin-destination data table, dynamic traffic information data and historical traffic data. The dynamic traffic routing service computing grid includes multiple dynamic traffic routing computing nodes and generates traffic route(s) using the traffic network travel time predictions.

    摘要: A centralized scheduling server for scheduling fine-grained near real-time applications includes network ports, a central managing application, functional library(ies) and service processes. One port communicates with processing nodes over a private computer network. Processing nodes include processing node report processor node status to the server and execute scheduled tasks. The other port communicates with user devices through a public network. The central managing application manages fine-grained near real-time application. The functional library provides middleware core functionality. The service processes include: a resource manager, a submitter to place tasks on a task queue; and a dispatcher to dispatch tasks to processing nodes. A work flow process runs an optimized scheduling algorithm.
