With mobile agent technology, anurban-traffic management system based on Agent-BasedDistributed and Adaptive Platforms for Transportation Systems(Adapts) is both feasible and effective. However, the large-scaleuse of mobile agents will lead to the emergence of a complex,powerful organization layer that requires enormous computingand power resources. To deal with this problem, we propose aprototype urban-traffic management system using multi agentbased intelligent traffic clouds. Cloud computing can help us tohandle the large amount of storage resources and masstransportation of data effectively and efficiently.Keywords— Adapts, Intelligent clouds, Traffic management,mobile agents. I. INTRODUCTIONIBM introduces urban traffic management system in the yearof 1956. Today, transportation research and development isno longer a field dominated by civil, mechanical, operationsresearch, and other traditional engineering and managementdisciplines. Rather, computer sciences, control,communication, the Internet, and methods developed inartificial intelligence (AI), computational intelligence, websciences, and many other emerging information sciences andengineering areas have formed the core of new ITStechnology and become integral and important parts ofmodern transportation engineering. Cloud computing controlthe traffic allocation process provides optimal solution withfive stages specification. In the first phase, computers werehuge and costly, so mainframes were usually shared by manyterminals. In the 1960s, the whole traffic management systemshared the resources of one computer in a centralized model.Introduction of large-scale integrated circuits and theminiaturization of computer technology, the IT industrywelcomed the second transformation in computing paradigm.In this paradigm, microcomputer was powerful enough tohandle a single user’s computing requirements. At that time, Fig 1. The paradigm of traffic management Systems.the same technology leads to the appearance of the trafficsignal controller. Each TSC had enough independent In phase three, local area networks (lans) appeared to enablecomputing and storage capacity to control one period, resource sharing and handle the increasingly complexresearchers optimized the control modes and parameters of requirements.

  2. 2. Cloud Computing for Intelligent Transportation Systemrequiring a runtime environment, mobile agents can run three databases (control strategy, typical traffic scenes, andcomputations near data to improve performance by reducing traffic strategy agent), and an artificial transportation system.communication time and costs. This computing paradigmsoon drew much attention in the transportation field. Frommulti-agent systems and agent structure to ways of negotiatingbetween agents to control agent strategies, all these fieldshave had varying degrees of success. Now, the it industry hasushered in the fifth computing paradigm cloud computing.Based on the internet, cloud computing provides on demandcomputing capacity to individuals and businesses in the formof heterogeneous and autonomous services. With cloudcomputing, users do not need to be aware of or to understandthe details of the infrastructure in the ―clouds;‖ they need onlyknow what resources they need and how to obtain appropriateservices and those resources, which shields the computationalcomplexity of providing the required services. In recent years,the research and application of parallel transportationmanagement systems (ptms), which consists of artificialsystems, computational experiments, and parallel execution,has become a hot spot in the traffic research field. [3], [4]Here, the term parallel describes the parallel interactionbetween an actual transportation system and one or more of itscorresponding artificial or virtual counterparts. [1], [5] II. AGENT BASED TRAFFIC MANAGEMENT SYSTEMAgent technology was used in traffic management systems asearly as 1992, while multi-agent traffic management systemswere presented later. [5] However, all these systems focus onnegotiation and collaboration between static agents forcoordination and optimization. [6–8] In 2004, mobile agenttechnology began to attract the attention of the transportation Fig 2. Organizational layers of Agent based Distributedfield. The characteristics of mobile agents—autonomous, Transportation Systemmobile, and adaptive—make them suitable to handling theuncertainties and inconstant states in a dynamic As one traffic strategy has been proposed, the strategy code isenvironment.[9] The mobile agent moves through the network saved in the traffic strategy database. Then, according to theto reach control devices and implements appropriate agent’s prototype, the traffic strategy will be encapsulatedstrategies in either autonomous or passive modes. In this way, into a traffic strategy agent that is saved in the traffic strategytraffic devices only need to provide an operating platform for agent database. Also, the traffic strategy agent will be testedmobile traffic agents working in dynamic environments, by the typical traffic scenes to review its performance.without having to contain every traffic strategies. This Typical traffic scenes, which are stored in a typicalapproach saves storage and computing capacity in physical intersections database, can determine the performance ofcontrol devices, which helps reduce their update and various agents. With the support of the three databases, thereplacement rates. Moreover, when faced with the different MA embodies the organization layer’s intelligence. Therequirements of dynamic traffic scenes, a multi-agent system function of the agents’ scheduling and agent-oriented tasktaking advantage of mobile agents will perform better than decomposition is based on the MA’s knowledge base, whichany static agent system. In 2005, the Agent-Based Distributed consists of the performances of different agents in variousand Adaptive Platforms for Transportation Systems (Adapts) traffic scenes. If the urban management system cannot dealwas proposed as a hierarchical urban traffic- management with a transportation scene with its existing agents, it will sendsystem.[10] The three layers in Adapts are organization, a traffic task to the organization layer for help. The traffic taskcoordination, and execution, respectively. Mobile agents play contains the information about the state of urbana role as the carrier of the control strategies in the system. In transportation, so a traffic task can be decomposed into athe follow-up articles, both the architecture and the function combination of several typical traffic scenes. With knowledgestatic agents in each layer were also depicted in detail of about the most appropriate traffic strategy agent to deal withmobile traffic control agents were defined clearly. What’s any typical traffic scene, when the organization layer receivesmore, a new traffic signal controller was designed to provide the traffic task, the MA will return a combination of agentsthe runtime environment for mobile agent. Currently, Adapts and a map about the distribution of agents to solve it. Thisis part of PtMS, which can take advantage of mobile traffic way, this system takes advantage of the strategy agent tostrategy agents to manage a road map. The organization layer, manage a road map. Lastly, we set up an ATS to testwhich is the core of our system, has four functions, performance of the urban-traffic management system basedagent-oriented task decomposition, agent scheduling, on the map showing the distribution of agents. ATS isencapsulating traffic strategy, and agent management. The modelled from the bottom up, and it mirrors the real urbanorganization layer consists of a management agent (MA), transportation environment.[11] because the speed of the 569

To achieve this superior performance, however, testing a large amount of typical traffic scenes requires enormous computing resources. Researchers have developedFig 3.

In our test, we used a 2.66-GHz PC with a need large computing resources to run many agents.1-Gbyte memory to run both ATS and Adapts. Theexperiment took 3,600 seconds in real time. The number of IV.

If we set the time threshold to 600 seconds, the of agents in ATS need vast amounts of storage. Similarly,maximum number of intersections in one experiment is only numerous traffic strategy agents and relative information such12. This is insufficient to handle model major urban areas as control performances about agents under different trafficsuch as Beijing, where the central area within the Second Ring scenes also consume a lot of storage resources. Finally, theRoad intersection contains up to 119 intersections. scale of decision-support system requires vast amounts of data aboutseveral hundreds of intersections. Furthermore, a complete the state of urban transportation.

It could alsodeal with different customers’ requests for services such asstorage service for traffic data and strategies, mobiletraffic-strategy agents, and so on. With the development ofintelligent traffic clouds, numerous traffic managementsystems could connect and share the clouds’ infinitecapability, thus saving resources. Moreover, new trafficstrategies can be transformed into mobile agents so suchsystems can continuously improve with the development oftransportation science. VII.

SUMMARYIncreased traffic congestion and the associated pollution areforcing everyone in transportation to think about rapidchanges in traffic processes and procedures to keep ourmobility safe, comfortable, and economical. Cloud computingbased intelligent transportation systems (ITSs) concept hasrecently emerged to meet this challenge. Many people see thisemergence as part of normal evolutionary adaptation to newtraffic conditions and technology. They consider current ITSapplications perfectly adequate to the times and a safer, wiserresponse to today’s and tomorrow’s transportation problems.REFERENCES [1].
