In this paper, we studied the technologies used in a dynamic fleet management system. A dynamic fleet management system is being divided into four technological fields: the fleet management system control centre the on board technologies and vehicle mobile data terminal the mobile and satellite communication infrastructure The fleet management system control centre is the core of a Fleet Management System. The Fleet Management system control centre is responsible for obtaining, processing and distributing information for better use of the system, the infrastructure and the services. The control centre includes all systems and tools necessary for providing guidance to the vehicles as well as management of the fleet. Technologies included in this field are: Electronic Data Interchange, Push Technology, Floating Car Data, Application Service Providers, Remote Sensing, Geographic Information System, Geofencing, Agent-based computing, and Front-End Intelligence. The on board technologies are the technologies used on the vehicle to acquire all the necessary data in order to have a clear view of the status of the vehicle, its freight and its position. All this information is transmitted with a selected communication system to the control centre. The on board system can also provide bi-directional communication with the driver and the router operator in the control centre in order to reschedule the vehicle’s route. Technologies included in this field are: Mobile Data Terminal, Sensors, Controller Area Network, Wireless Sensor Network, GPS receiver, Smart mobile phones and PDAs. The mobile and satellite communication infrastructure is the technological field that is used for the communication between the on board terminal and the control centre. Technologies included in this field are: Global System for Mobile Communications, General Packet Radio Service, 3G, 4G, Bluetooth, Zigbee, Radio Frequency Identification and Global Positioning System.Finally we have presented cybercars whose technologies are emerging, with some of them to have already been applied in industrial scale and others to be in a prototype state. Nevertheless this technology is the future of the fleet management systems. Technologies included in this field are: Obstacle avoidance, Navigation and communication, Parallel parking, and Platooning. For every technological field that is presented, relatively papers are being demonstrated for someone to understand better the technology and its application.
