Moreover, as cities around the world face the dilemma of urban congestion and migration, ITS provides the solution. The three giants in this regard are the US, Europe and Japan, who have developed the ITS architecture and are continuingly underway for developing and testing new technologies. The developing countries now have the opportunity to provide for the essentials for the deployment of ITS and work on already established standards on ITS. The role of the local governments in this regard is crucial. The government needs to build the capacity of the employees to ensure that they are able to work on the new components of the ITS. Similarly, an institutional setup has to be proposed to develop and establish a wing for the development of ITS and technological requirements to ensure that the data transfer and sharing is adequately provided. The paper presents the solution of a step-by-step approach for such deployment and uses the case of Pakistan to illustrate examples on how to work. The institutional setup is the main requirement for the deployment of ITS in Pakistan, as there is no single ministry for transportation and all the authorities have been devolved to the provincial governments. An architectural setup for the deployment of ITS has also been proposed in the paper and will ensure that work proceeds efficiently.

Automated vehicle classification(AVC) system in operation was changed 5-category classification system to 6-category classification system by adding category 6, micro cars made by discounting 50% of category 1 since 1996. The 50% discount, which applied to only 800cc, has been expanded to less than 1,000cc since Jan. 2008. Since then, the new micro cars of 999cc were classified into category 1 by the vehicle classification system. As a result, the chances of eluding toll are getting higher and users’ complaints increase. To solve the problems, we propose the improved toll collection system that can classify the new micro cars by recognizing car license plate in entry station of closed tollgate.

The objective of TRIP is to provide consumers, enterprises and vendors with real-time traffic information to be directly used for dynamic route guidance applications. This has an impact in the form of reduced road congestion as motorists are diverted away from traffic bottlenecks, increasing road safety and satisfaction amongst motorists from the enhanced experience, whilst addressing environmental concerns. In this project, a pilot trial was conducted to evaluate the reliability and effectiveness of processed traffic information. Reported data was correlated with data collected through real drives to determine the similarity between the two. Simulations were performed to estimate the effect of traffic-aware routing on overall travel time. Since its implementation, processed data from TRIP has powered numerous free as well as commercial, traffic-aware applications and solutions in Singapore. These include an RDS-TMC service, mobile applications for traffic advisory, a Twitter feed, display on web maps, and use in online and in-vehicle traffic-aware routing and navigation. In this paper, we share our experience in the development and deployment of TRIP, discussing the salient points of TRIP, in the use and processing of road traffic data collected by LTA to provide standardized machine-interoperable traffic information to in-vehicle systems over wireless media. We also share the results from the pilot trial drives and discuss the challenges and outcomes in providing services and applications to consumers.

This paper describes the detailed operational mechanisms of the force-off modes used in traffic signal controllers and CORSIM. In addition, the delay performance of four force-off modes has been examined through simulation experiments under the coordinated-actuated signal operations environment. According to the simulation results, the fixed force-off mode showed the best performance for all volume-to-capacity ratios, and when considering short-term fluctuations in traffic volume, the fixed force-off mode again outperformed the floating force-off and CORSIM-embedded modes for the demand variations considered in this study. The results support that the fixed force-off mode is suitable for coordinated-actuated signal operations.

Due to high daily trips and different car types Taipei metropolitan area is chosen as the case study. Firstly, the content of Telematics service for urban car drivers are identified as the segmentation variable and key factor facets for Telematics service content are renamed by using factor analysis. Then, the SVM method is used to classify customer groups which are named by analysis of variance (ANOVA) and market segmentations are described with demographic, lifestyle and car patronage variables by using cross analysis and Chi-squared independence tests. Finally, this paper discusses empirical results to provide valuable implications for better Telematics service content marketing strategies in the future.

Especially in urban area, there are many tall buildings and it makes wide-shadow area, thus the GNSS receivers have low reliability, availability, and integrity. But combined GPS/GLONASS is expected to reduce these problems of satellite navigation. In the previous research, combined GPS/GLONASS receiver enhanced the probability of obtaining position from 87% to 98% using standalone algorithm in Teheran Street, Seoul, Korea. And RTK algorithm can improve the positioning accuracy. But for RTK algorithm, the wireless network to receive the observations from base station should be peaceful. And phase measurements have to be acquired stably. Unfortunately, it's very difficult in urban. That’s why the positioning results by various algorithms have to be given. Navigation performance based on embedded board must be evaluated. Because navigation algorithm for land vehicles should be operated using embedded board with low CPU in real time. In this paper, combined GPS/GLONASS RTK receiver for embedded platform was implemented and evaluated by driving experiment in urban area. In the experiment, positioning results was calculated using Evaluation Kit using RMI AU1250 CPU in real time.

Input-Out analysis is employed in order to estimate the impacts. The impacts are estimated in two accounts: Participants expenditure and Expenditure by Organizing Committee (OG). Three scenarios reflecting different levels of expenditures by OG and success in attracting participants and visitors are assumed. The impacts are measured in terms of production (sales volume), value added and employments (jobs). The result of this paper shows that the Congress will bring a very positive impact on Busan's economy, especially on employments.

In general, there are some methods to calculate the quantity of greenhouse gases in road. However, these methods did not contain further accuracy and had many assumptions for calculating the quantity of greenhouse gas. We tried to improve accuracy in calculation method and consider characteristics of vehicles such as a kind of cars, speed and a variety of fuels. In order to improve calculation accuracy, we proposed "tier 2 and 3 method" in computing CO2 emission. Also, we adjusted above two methods to calculate CO2 emission in test site(Nam-Bu arterial). As a result, there are few differences in two methods. The result applied tier 2 method is 0.1% lower than the result adjusted tier 3 method. We hope the our research can help your understand to measuring CO2 emission by considering vehicle's activities.

The queue of auxiliary convergence road is selected as monitoring variable in the coordinated control strategy, and downstream intersection cycle, split and auxiliary road green time are calculated. The control variables small-step adjustment algorithm is presented. The throughput flow duration of exit-ramp by the coordinated control strategy decreases at least 10% than by the fixed control strategy. Combined with road network delay data, the simulation results show the effectiveness of the coordinated control strategy.

The vehicle has independent drives on each wheel except for the front axle. The main objectives of controller are to automatically steer the vehicle so as to follow the given reference path within permissible lateral deviations. We have used a three input-three output linearised model which is derived from the nonlinear vehicle dynamic model. For the purpose of making the controller be simple and tunable, a decentralized low-order control configuration is considered and has been designed by using the characteristic ratio assign (CRA) method. It is shown by simulation results applied to the nonlinear dynamic model that the resulting linear controller achieves the design objectives successfully.

Oct. 2009) and supported by ministry of knowledge economy (MKE) of Korean government, and then summarizes its achievements. To reduce the number and severity of vehicle-pedestrian accident by active safety vehicle (ASV), false alarm rate should be minimized. For this purpose, we developed critical area-centered pedestrian detection system which recognized locations of parked vehicles along the road-side then investigated only areas behind the parked vehicles. After evaluating four different approaches, sensor fusion of near infrared (NIR) vision and scanning laser radar was selected as the optimal. Although feasibility of braking and suspension for pedestrian protection was evaluated, only braking was proved to be useful.

The urban traffic problems can be defined as general problems for smooth traffic flow including maintenance of mass transportation system according to suddenly increased population, traffic regulations for vehicles and pollution problem. As a method for solving traffic jams, one of the traffic problems of late, interest in Intelligent Traffic System(ITS) is increasing sharply, which is a system managing traffic demand by providing passers with information on traffic state of path and road conditions before they pass the road through ATIS, a field of ITS. Methods for providing Information for passers are traffic broadcasting, variable message signs, Internet and ARS, especially broadcasting media and variable message signs are mainly used. Variable message signs(VMS) is used on the roads as a method for providing information to promote smooth traffic flow and safety and prevent traffic accidents in advance by providing drivers with various information while driving. Recently, as ITS industry has been vitalized and technical factors of VMS have developed, various kinds of information is provided but the effect of VMS has not been maximized due to its limited type. Therefore, this study intends to provide methods for effective information transfer by analyzing driver's visual behavior characteristics for VMS and presenting a basis for maximizing VMS effect after considering read by expression type.

In the point of view, HDCCTV Solution which converts and transfers from SMPTE to HD-SDI is proper system for ITS infrastructure. The problems like blurring and delaying on video are occurred in network transmission. But, there’s no problems like those on the video since HDCCTV solution applies uncompressed data transmission. In result, high quality video of HD/Full-HD is transferred in real time so that it is possible to make appropriate and effective ITS by giving instant analysis and information offering.

The purpose of this paper is to evaluate the performance of existing domestic high-performance roadside barrier by applying finite element analysis and to give improvement to satisfy the condition of a more severe crash. KEC-SB5-02 was chosen among existing domestic high-performance rated barriers (SB5) as the target model to be analyzed. KEC-SB5-02 roadside barrier improved the safety performance and aesthetics of the conventional W-type and Thrie-type beam roadside barrier model, it consists of reinforced steel pipe posts with 2m spacing and two C-type cross beam. A finite element model of KEC-SB5-02 roadside barrier was developed and its adequacy was evaluated through calibration and actual vehicle crash test results. Computer simulations for a variety of impact conditions considering occupant safety were made to determine the maximum impact conditions of the KEC-SB5-02 barrier, these are 1300kg for impact mass, impact velocity of 110km/h and impact angle of 20 degree. Impact Conditions of SMART Highway Road safety Facilities suggested impact conditions to minimize the degree of damage and punctuality and safety after car-barrier collisions for a highway with a design speed of more than 120km/h.

Recently, ITS applications have begun to provide information through Variable Message Signs (VMS) and the Lane Control Systems (LCS) recommending 20% or 50% speed reductions because of poor visibility. There are three possible kinds of countermeasures against fog such as removing the fog, improving visibility, and giving guidance regarding speed reduction. The removal of fog is regarded as impractical, and the ability to improve visibility is low. It is then desirable and practical to evaluate the thickness of the fog, provide information on the fog, and give appropriate driving guidance to drivers. This study suggests additional traffic safety countermeasures such as a variable speed guidance system (VSGS) be used on the ITS in foggy conditions. The safe speeds can be determined by the method developed in this study.

Incident data (near-miss data) gathered from drive recorders become to be utilized instead of accident data. In this paper, incident data sets of the three regions, Tokyo 23 wards, Shizuoka city, and Yurihonjo city, are used. The data collected in a specific region has its own particular characteristics of the region. Data sets of some representative regions with variety of features are required to estimate the effectiveness of active safety measures in all Japan accidents. This paper first introduces two incident databases for the three regions, then describes the characteristic of crossing incident in the regions, and proposes traffic safety countermeasures for them.

Although various systems to detect drowsy driving have been installed in vehicles, only to detect drivers’ drowsiness is not enough to keep safety driving. Therefore ways of stimulating the drivers’ vigilance (by delaying the creeping drowsiness) are in the spotlight. This paper describes a method where we propose combining steering wheel vibration with the auditory stimulus for the drowsy drivers to raise their vigilance upon the stimulus. We carried out experiments on driver vigilance as understood from the physiological signals, using a driving simulator. As a result, the blink duration was decreased because of the given stimulus combined with steering wheel vibration and sound. And, the progress of driver’s drowsiness was delayed by about 2.5 times compared with the case when no stimulus was given. Combined stimuli were also found to be more effective than by a single stimulus.

An evaluation of driver’s behavior while parking into garage without any parking support system was performed focusing on the variation of the behavioral characteristics by driver’s skill level. The evaluation result shows that the improvements of the system performance reduces the mental load and burden, and the time needed for parking in significance level of 5%.

In fact accidents by wrong way driving occurred at the rate of about twenty times per year and most of those are serious accidents. From 2003 to 2007 there have been 84 accidents caused by wrong way driving on expressways operated by NEXCO-WEST. Among those case, 54 accidents of the cases include casualties and injuries and among 75 accident cases known the age data, 34 cases were caused by drivers aged 65 or over. Considering Japan’s rapidly aging society, Taking countermeasures against traffic accidents by wrong way on expressways is very important. NEXCO-WEST is making various efforts on reducing wrong way driving case. For example, we have settled post cones between ramp and expressway and painted arrows on the roadway surface. But it is not enough to prevent wrong way driving cases. So we have been taking countermeasures using ITS technology against traffic accidents by wrong way. One of the countermeasures is a wrong way drive prevention device using warring sign and sensors. the others are innovative countermeasures in developmental or planning phase. In this paper we explain it.

To support high-quality service to User Equipments equipped in vehicles, fast and seamless handover must be guaranteed in high-speed mobility condition. In this paper, we propose a handover prediction technique for next-generation navigation systems. We introduce a geometric method to select the essential reporting information for sBS to estimate the best handover candidate cell using navigating information. And the condition for the handover prediction trigger is also determined. The objective of the proposed technique is to minimize the number of reporting events for handover while improved accuracy of the handover prediction including the handover candidate cell and the handover timing.

There are various types of accessories researched to aid the like of these many visually disabled persons. Especially, there are various method researched such as absolute coordinate recognition using GPS, distance recognition using a ultrasonic sensor or camera, position recognition methods using USN or ZigBee, etc., which are suitable for the visually disabled persons who should recognize their surrounding environments by leaning on their sense of touch and grasp the route of their destination. However, the position recognition method using a communication device catches the exact position via electromagnetic wave interference or has a limited use range. In order to overcome this limit, this research tried to use a two-dimensional barcode method that is accurate in input, simple in systems, and costfree in maintenance. Direction and position information and routes were made to be written by applying a two-dimensional barcode to the existing braille point blocks for the visually disabled. And a COMS type of subminiature camera applicable to a cell phone due to its small power consumption was attached to a blind stick. The attached COMS camera was made to realize a system of preventing the separation of braille point blocks for the visually disabled by tracking the braille point blocks for the visually disabled in real time and predicting the route, and a position information provision system by recognizing the information of a two-dimensional barcode.

On the other hand, the smoother traffic brings traffic safety (by alleviating driver stress) and reduces environmental impact, the benefit of which can be shared by society at large. This paper discusses the importance of vehicle detectors used for various purposes and the smoother traffic flow to be brought about by their effective operation and maintenance.

The Tokyo Metropolitan Police Department is responsible for maintenance of public safety and order in Tokyo and realizing safe and comfortable road traffic is part of such responsibility. The Tokyo Metropolitan Police Department Traffic Control Center is the core facility established for this purpose. The Traffic Control Center collects and captures the road traffic information (traffic volume, congestion, traffic accidents, road constructions, etc) across Metropolitan Tokyo in real time, for provision to drivers and for use in traffic control by regulating traffic lights. In today’s society where vehicles are used for transportation and commodity distribution to support our social life, the role the Traffic Control Center plays is significant and its full potential is requested to be maximized. The Road Traffic Control Console was developed for this purpose. The console which is equipped with many functions may be referred to as a “small traffic control center”
