This project is proposed to develop the set of core technologies for ubiquitous transportation(i.e., u-Transportation) systems. The u-Transportation systems are a new concept meaning the ubiquitous transportation environments where drivers, passengers, pedestrians, as well as system operators and managers can give and take the information and services required for their individual traveling and operating purposes, without any limitations of time, place, and device. To build the u-Transportation systems, this project has developed three (3) main technologies: i) the system engineering technology for integrating u-Transportation sub-systems, ii) the core technology for realizing u-TSN(ubiquitous Transportation Sensor Network), and iii) the application service technology for operating and managing traffic flows by the u-Transportation systems. Those technologies are expected to make it possible for all individual users to make any decisions by playing substantial roles in giving and taking transportation information and services between the user(vehicle), infrastructure, and center. These three (3) main technologies are described as the following three projects, respectively.

First, the system engineering technology for integrating u-Transportation sub-systems has included five specific tasks: a) the development of u-Transportation technology for system engineering is defined as the integrating and fusing technology based on the system engineering methodology employed to maximize the potential performance of the target u-Transportation sub-systems, which are composed of u-TSN technologies and application service technologies, b) the development of the u-Transportation architecture is to optimally design the u-Transportation sub-systems. This task includes definition of services and functions for each sub-system, potential scopes and plans, boundaries of each sub-system, and their integrating framework, in order to satisfy a set of conditions for u-Transportation systems such as ubiquitous applicability, transparency, and transcendency, and by successfully accomplishing the interoperability and compatibility, c) the study on data processing and analyzing obtained locally from ubiquitous transportation information is the research task to define and analyze the components of traffic information system under the u-Transportation systems, and to examine the requirements of defined key components. d) the study on evaluations of u-Transportation systems and their strategy establishment is the other research task to develop an experimental simulator enabling to consider traffic and communication functions for establishing traffic strategies and communication algorithm under the u-TSN and to examine the strategies t-conversion network using the simulator. e) the building of testbeds and evaluation of application services under the u-Transportation systems. This task includes the selection of the best sites to build the sub-systems composed of u-Transportation main technologies, and the set of application services and their evaluation to compare with the existing ITS services.

Second, the core technology for realizing u-TSN(ubiquitous Transportation Sensor Network), meaning technologies enabling to communicate vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I). This project mainly consists of six (6) tasks: a) the development of u-TSN network architecture is comprised of system design, system engineering, and network computing technology. In addition, field of test (FOT) has been conducted to deploy u-TSN demo services, b) the base technology that process the large quantity information has been studied, since the amount of information under u-T environment is more massive than that of the ITS environment. This study has been proposed to develop the u-Transportation center(UTC) infra architecture and information processing architecture for processing the simultaneously occurring frequently UVS data rapidly and accurately, c) the u-Transportation Sensor Network(u-TSN) terminals have been developed, namely ubiquitous Vehicle Sensor(UVS) and ubiquitous Infrastructure Sensor(UIS) development. For realizing the u-TSN environment, the dedicated communications technologies and networks have been developed to collect and offer faster and more accurate traffic information. This task has considered hardware and software systems to transfer traffic information for V2V, V2I, I2I, and I2C communications, d) the IMU system, as an embedded board, is the valuable technology enabling to provide relative vehicle motion information in UVS. That is, the developed UVS terminal can estimate 3-D vehicle motion information by sensor fusion algorithm to interact with u-TSN total system technology, e) the precision mobile positioning system used for u-TSN has been developed originally based on the precision GNSS system. Attached in UVS, this system is used to acquire precise position of moving vehicle. This system is divided into H/W portion and S/W portion. The H/W development requires GNSS receiver design and other core part design. The development of precise correction algorithm has been developed and implemented to enable precise positioning with low-cost GNSS receivers mounted on highly-dynamic vehicle. The navigation algorithm with combined GPS and GLONASS has also been developed and implemented for improving the accuracy and integrity which depend on the number of visible satellites. f) the last task is to support testbeds building and evaluation of the u-Transportation systems.

Third, the application service technology for operating and managing traffic flows by the u-Transportation systems is mainly the research project to develop new services called u-Transportation services, using the u-Transportation core technologies. This project includes five (5) specific tasks; a) the integrated scenarios for u-Transportation operation and management has been drawn up, and the macro traffic optimization strategy has been developed, and the forecasting technology based route searching algorithm has been developed, b) the integrated data have been generated through experimental test, and the forecasting technology is developed using the integrated data analysis, based on understanding issues of u-Transportation management and macro traffic monitoring, when the u-Transportation system is integrated with existing detector system, c) the transportation management studies have been implemented under the uninterrupted and interrupted traffic flows, which consists of simulation test-bed experiments, algorithm elaboration, analysis of function demand for stability control system, and making field demo-service operation scenario, d) the operation & management scenario at time of disaster and calamity has been developed, and the guideline of nation, city and state has aslo been suggested, e) the service technology, which can upgrade GIS-based transportation information providing service under existing ITS circumstance, has been developed. And the methods providing high-quality transportation information - section travel time, macro traffic indicators, etc. - collected under the ubiquitous circumstance has also been developed.
