City bus information management and dispatch decision support system based on network

Abstract

The invention discloses a city bus information management and dispatch decision support system based on network, wherein the system comprises a main server and an autonomy field in a distributed network computing system; and the main server comprises a grid portal, a workflow engine and an authentication center; the autonomy field comprises a field information servicing module, a field job manager, a field manager and a resource node assembly. The invention mainly solves two key problems: how to dispose the communication application service in the existing grid environment, namely service gridding disposition; and how to perform the bus decision support using the existing service, namely grid service instantiation process. The grid is used to specify and construct an urban traffic decisionsupport system, and various decision resources are encapsulated to form a grid service and distributed in each independent grid calculation node to perform the multi-node synergy dispatch. The systemhas high resource sharing, high throughput calculation and high team work.

Description

technical field [0001] The invention belongs to the field of intelligent public transport and decision support, in particular to a grid-based urban public transport information management and dispatch decision support system. Background technique [0002] With the rapid development of the national economy, the total flow of people and materials continues to increase, and the contradiction between the continuous development of cities and the effectiveness of urban space resources makes the development of urban public transportation systems more and more important. Due to the lack of advanced technical means, the collection and management of traffic information has always lagged behind the needs of development, which has brought a great impact on the smoothness of urban traffic and the safety of people and vehicles, and has comprehensively restricted the development of urban economy. [0003] It is an inevitable choice for cities to give priority to the development of public t...

AI Technical Summary

Problems solved by technology

First of all, the public transportation system in most cities in my country generally has a low level of informatization, and the management and operation have long been carried out manually and relying on experience. Therefore, the development of an informatized and intelligent urban public transportation system is an inevitable requirement for development; secondly , it is difficult to interact with each subsystem in the current system. In order to dynamically obtain real-time passenger flow information, ensure that vehicles run on time, and enable travelers to share traffic travel information in real time through the vehicle information service system, we must provide a more convenient information exchange and sharing Moreover, the traditional intelligent transportation system uses centralized processing, which has high operating costs and lacks the ability to deal with emergencies. Therefore, in order to better store and calculate massive traffic information, we need to design a system that is more suitable for processing Distributed resources, a system with real-time traffic information processing capabilities
