As our society is becoming an aging society, there is an increasing number of the elderly. Recently, mobility handicapped like the elderly and the disable take part in many social activities. It is required public transportation systems for them. Already, the traffic policy for mobility handicapped including pregnant woman and child, has been established in many cities. Particularly, the convenience of mobility for the handicapped in the urban rail stations is depend on a pedestrian facilities like escalators and elevators. The pedestrian facilities have been built in urban rail stations without rules for mobility handicapped. To make the more convenient and more safe stations, the more study about mobility handicapped and non-mobility handicapped is needed. This paper preferentially discusses the pedestrian facilities with other convenience facilities in urban rail stations. This paper explains also their preference, relative satisfaction and importance for the convenience facilities including the a pedestrian facilities in urban rail stations and makes clear the difference between both groups.

In this paper, delay performances are evaluated and compared for three dual-plane switch architectures; dual input queue/dual switching plane (DQDP The terms of DQDP, DQDP-PS and DQDP-GQ were not used in [Turner88], [Lee96] and [Son97]. All these tern are designated in this letter for convenience.) switch, DQDP with plane selector (DQDP-PS) switch and DQDP based on output group queueing (DQDP-OGQ) switch. We show that under random traffic these switches give almost identical delay performances to that of the output queueing switch but under bursty traffic only the DQDP-PS and the DQDP-OGQ switches ran do.

In order to prevent the global warming, Korea has had a ratification to the Kyoto Protocol which is specified the air pollution level should be lower the condition of the year 1990 until the year 2012, in hence the traffic system produced mostly the air pollution has been faced to big change. According to the reinforcement of higher level for environmental condition, alternative way to the conventional traffic system is required, so that is fuel cell technology of commercialized R&D program used by hydrogen fuel, and further for the optimized high energy efficiency it has been considered the advanced development of traffic system used the conventional railroad system. But it is moreover expected the huge amount of initial investment, so at the current, next new traffic system is needed. This study is for the improvement of urban traffic system in domestic which should be seriously changed for environmental friendly through the reduction of air pollution by fuel gases of vehicle and human convenience to be easily approached. In hence it is proposed the development of superior high efficiency-'Fuel-cell Rubber-tired Tram' system manufactured by the composite car-body.

Information technology improves convenience, safety, and performance of automobiles. Recently, a lot of algorithms are studied to provide safety and environment information for driving, and traffic sign recognition is one of them. It can provide important information for safety driving. In this paper, we propose a method for traffic sign detection and identification concentrating on reducing the computation time. First, potential traffic signs are segmented by color threshold, and a polygon approximation algorithm is used to detect appropriate polygons. The potential signs are compared with the template signs in the database using SURF and ORB feature matching method.

Intelligent transportation system (ITS) has been introduced to maximize the efficiency of operation and utilization of the urban traffic facilities and promote the safety and convenience of the users. With the expansion of ITS, various traffic big data such as road traffic situation, traffic volume, public transportation operation status, management situation, and public traffic use status have been increased exponentially. In this paper, we derive structural characteristics of urban traffic according to the vehicle flow by using big data network analysis. DSRC (Dedicated Short Range Communications) data is used to construct the traffic network. The results can help to understand the complex urban traffic characteristics more easily and provide basic research data for urban transportation plan such as road congestion resolution plan, road expansion plan, and bus line/interval plan in a city.

Urban area is being continuously grown traffic volume due to diverse economic activities. Especially, the traffic noise, which occurs on the road of passing by residential district, is dropping quality of life as negative element of obstructing sleep at night. This study analyzed relationship between the officially notified land price and the traffic noise in residential district by using the estimating equation of traffic noise and GIS. As a result, the officially notified land price on a parcel of residential district along the road was indicated to be higher than a parcel where is located in other place. Even traffic noise was indicated to be higher. Accordingly, a plan is judged to be necessarily arranged that can be made appraisal of the officially notified land price, which is reflected the convenience of life and the quality of life at the same time in consideration even of traffic noise together as element of appraisal given evaluating the officially notified land price in residential district where is located in the downtown.

C-ITS is an intelligent transportation system that can improve transportation convenience and traffic safety by collecting, managing, and providing traffic information between components such as vehicles, road infrastructure, drivers, and pedestrians. In Korea, road infrastructure is being built across the country through the C-ITS project, and various services such as real-time traffic information provision and bus operation management are provided. However, the current state-of-the-art road infrastructure and information linkage system are insufficient to build C-ITS. In this paper, considering the continuity of time in various spatial aspects, we proposed a group-type network-based traffic situation recognition system that can recognize traffic flows and unexpected accidents through information linkage between traffic infrastructures. It is expected that the proposed system can primarily respond to accident detection and warning in the field, and can be utilized as more diverse traffic information services through information linkage with other systems.
