This research proposes the methodology of detection and estimation of road congestion using cellular phones. We survey the road that is well-known as one of the most congested roads in Bangkok, Thailand. In our survey, we collect two kinds of information, cell dwell time (CDT) using a cellular phone and velocity and position using Global Position System (GPS). To categorize CDT according to cell coverage area (CCA), we have also collected local area code (LAC) and cell ID. We collect data into "Green" survey and "Red" survey, and analyze the data using two models: Junction model and Link model. The results have shown that there is significant difference between the two surveys. However, the accuracy of traffic flow estimation is tentatively decreased as the CCA size is deceased.

In this paper, we proposed the method for calculating the Protection Ratio (PR) of the Advanced Television Systems Committee (ATSC) broadcasting system from the Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) broadcasting system through the computational experiment. For this, the transmitter/receiver of the ATSC system and transmitter of the ISDB-T system were modeled. By integrating those, the computational simulator for setting up the PR of the ATSC system from the ISDB-T system was implemented. The ATSC TV signal was regarded as the desired one and the ISDB-T TV signal was regarded as the interfering one. In order to simplify the simulation complexity, it was modeled sending/receiving signals in the Intermediate Frequency (IF) band instead of those in the RF band. And it was assumed that one received signal was considered in the channel modeling and there's no Additive White Gaussian Noise (AWGN). By using the calculated PR value, the coverage prediction considering the interference was performed between the adjacent nations which use the different digital broadcasting system.

With the great development of economy and society, large quantities of bridge need to be monitored in the highway and the distance between two bridges located in different places may be even more than 50 kilometers. The remote transmission is the key premise for remote monitoring of several bridges or more (bridge group) at same time. In this paper, an effective remote transmission method is presented for health monitoring system of bridge group based on SDH technology. In the context, the remote communication principle of the proposed method is stated firstly and then the hardware and software configurations are given out respectively. Finally the availability of the remote transmission system is proven by the results from a real application example for health monitoring of four bridges in different places.

Transport telematics or intelligent transport systems (ITS) include a lot of tools and services from information and communication technologies. The paper presents an approach for ITS reliability analysis with evaluation petri net modelling with many specific aspects of reliability analysis and modelling: multilevel structural hierarchy; multifunctional objects of modelling; different nature of failures (hardware, software, human, organizational); heterogeneous components of the modelling system; open structure of ITS architecture and its model and others. The dynamic behaviour of the reliability model at various levels of abstraction is discussed on the base of analytical properties of Petri Net.

This is the first study for inside vehicle wireless communication system design with UWB technology under WiMedia standard. At first, MATLAB simulator has been developed then calculated BER in AWGR channel model. And it is confirmed adequacy of channel model compared with IEEE simulation model. And wireless transmission characteristics are measured with the following? conditions such as receiver on top of dashboard and transmitter on rear sheet, center of trunk etc. Then test result of BER and PER are compared with simulation model above those conditions. In case of wireless communication system design under IEEE802.15.3a and or WiMedia model with target 8% PER condition, inside vehicle wireless communication is capable for 3dB link margin for wireless communication with tweaking antenna gain and receiving NF for inside Vehicle communication system.

In this paper we focus on the performance improvement of reactive routing protocol of wireless ad-hoc networks by considering traffic load and geographical information of the network that are involved in routing procedure. A mobile node that already has or potentially will have excessive routing duty should act as a relaying node with relatively low probability. We use three parameters that are available in AODV: the size of routing table L, the expiration time of each route entry i in the table Δti, and the number of neighbors of each node j involved in routing nj. Simulation results from ns-2 show that our scheme gives significant improvement in terms of packet delivery ratio, end-to-end delay, and arrival jitter.

A road environment recognition system is presented. First, lane lines are detected based on our proposed Gaussian comparison function. Then a road prospective model is built on the basis of a new Gaussian semi-sphere approach to detect vanishing point. Using this model, three road parameters are computed, i.e. vehicle's transverse bias, yawing angle and the road slope angle. Obstacles such as vehicles in front of the current lane are also extracted. Simulation experiments prove the effectiveness of the system.

Besides collision avoidance and traffic monitoring, ship AIS (automatic identification system) information is very valuable in other fields of shipping industry. However, it's very hard for people in these fields to access ship AIS information directly. To satisfy their demands, several live AIS Web systems have been developed. Most of them, however, could be further improved in the aspect of user friendliness. By using Ajax technology, we tried to develop a new live AIS Web system to publish the real time AIS information to the public. The architecture and several key technologies of the system, such as AIS information database construction and accessing, sea chart tiling and rendering, AIS information rendering and so on, are introduced. The system shows that Ajax can enable users to view AIS information smoothly. Compared to the legacy systems, more natural user interact behaviors are supported by this system.

Transfer is the most obvious and important characteristic of intermodal and multimodal transport systems. In a Public Transport Information System (PTIS), the structure design of transfer data is the key point in building up the database of transit networks, for it not only concerns the efficiency of some main applications such as the shortest path search and the management of lines service, but also determines the design of Human-Machine Interface (HMI) which affects the efficiency of data access, management and maintenance. On the basis of the topology of the public transportation network defined by the European standard --TRIDENT, we propose 3 modes to organize the transfer data according to different constraints of data quantity, precision and accuracy. Finally, a conclusion is presented by the feedback of implantation and comparison.
