ITS is expected to be able to optimize the current public transport condition that has not been integrated through an ICT networks. In this paper is proposed a traffic management center (TMC) development used to monitor the fleet ’s movement and soon will be developed to control the fleet ’s movement. In this paper discusses from design to its performance of data communication protocol algorithm for communication between OBU cloud server as OBUs data collector and the TMC. Keywords: smart mobility, intelligent transport, vehicle monitoring, traffic management center. INTRODUCTION Intelligent Transport System (ITS) is a part that can support smart mobility. Smart mobility aims to decrease congestion, speed up movement, decrease the transportation cost and more environmentally friendly [1]. ITS also aims to improve the transportation users’s safety [2]. Generally, ITS needs a wireless data communication line for delivering message from a On board unit (OBU) device carried by a vehicle to a Traffic Management Center (TMC). The data communication line is also used for sending information to the road users. If seen from the needs, then the data communication protocol in ITS needed also diverse. The vehicles in Indonesia are currently still connected neither to each other (vehicle-to-vehicle, V2V) nor to a traffic controller (vehicle-to-infrastructure, V2I). This condition applies as well to public transportation in Indonesian big cities. As a result, the distance between public transport fleets are not optimized -- either they are to close or too far from each other. At the moment, public transportation in Indonesia actually has a periodic schedule, but because of the unpredictable traffic, the estimated time of arrival is often unpunctual. In order to fix this problem, a fleet movement monitoring system through existing wireless communication network is proposed in this paper. By monitoring locations of public transportation in a control center, an optimized public transport movement is expected to be achieved. To move digital information from one device to another, a protocol is needed. The protocol used in a communication data within the ITS system works above the communication data protocols that have been commonly used, so that the finishing process goes faster. The communication data protocols that are commonly used at the moment are communication data protocols based on Internet Protocol (IP). The problem description of this paper as follows: a) How is the system architecture to monitor the location of a vehicle that is moving in a TMC space? b) How is the optimal protocol on a communication system between OBU and TMC through a cloud server located on data center? In order to maintain the reliability of data communications between the OBU and the TMC, a reliable cloud server is introduced between them. This server takes main responsibility to acquire such a data transaction from many OBUs, as well as a main data center in the point of view of the introduced ITS concept. In addition, the cloud server serves data collector from distributed OBUs’ data. The TMC server finally can be consider as a user of data center server to run critical function of monitoring the vehicle through On Board Unit. Using such architecture, the Communication Division operators or technicians in the TMC may concentrate to their function to manage the traffic condition and public transport vehicles. METHODOLOGY ITS is a system with all the information technology and communication within vehicle, between vehicles (V2V) as well as between vehicle and the existing infrastructure (V2I). ETSI have also published Cooperative ITS (C-ITS) which connects various transportation modes [3]. Cooperative ITS promises a lot of convenience which can improve efficiency in both time and money. Willke et al in his publication has categorised ITS application especially to V2V that can be used to control the movement of fleet and also as information delivery media like data service, advertisement, street data and warning for traffic situations [4].
