本研究では、導入に関して議論が継続した富山県高岡市と途絶した山口県宇部市を対象に議論の継続に影響を与える要因について分析を行った。分析の結果、コンパクトシティ施策受容意識や居住地域の立地適正化計画の受容意識が継続に影響を与えていることが示された。高岡市の方が立地適正化計画と導入の認知度、導入の受容意識が高かった。宇部市では、の受容意識と公共交通重要性認知との相関分析の結果から、有意な負の相関が確認できた。宇部市では、新交通が将来的な公共交通ネットワークの充実に相反するものと捉えられていた可能性が示された。

There are many places where they have no efficient transportation, though they are being worried by traffic jam. To solve this problem we studied qualities and quantities of urban transport, and located some kinds of transportation to the adequate positions in the spectral field of traffic demand. Consequently we noticed that the construction cost is too expensive when the density of traffic is under some degree. In order to reduce the construction cost and business expenditure, we propose a light vehicle and high frequency system. To lower axle load, width of the car is contracted. This means reduction of axle load, at the same time, of carrying capacity. So high frequency system of trains is adopted. It will also present good service to the passengers.

This paper deals with a merging section of Personal Rapid Transit system. Several schemes have been proposed for the control of vehicles in PRT systems. In quasi-synchronous control systems, one flow of traffic must form a queue at a merging section in order to avoid the collision of vehicles. In other words, a queue is formed on one of the lines, which is called the sub line; the other line is called the main line. Basically, vehicles on the main line have priority. We propose a control strategy whereby vehicles on the main line are usually not stopped; vehicles on the main line are only stopped when the number of waiting vehicles on the sub line exceeds some specific number. Therefore, queues are formed on the main line and the sub line, respectively. This paper presents a fundamental discussion of the effects of the double queue and the relationship between traffic density and the behavior of traffic.

Three phase, AC feeding system for people mover system is described. The moving vehicle is assumed to be a current source of which position and current are determined by the run curve of the vehicle. Simulation of the feeding system is realized by AC electric circuit mesh method with the current source. This simulation is easily realized by the use of commercial simulator such as SPICE. With the SPICE, the dynamic operation of the thyristor converter on board can be simulated with the feeding system simultaneously. As a result, instantaneous analysis such as braking transient phenomenon or instantaneous harmonics can be simulated.

At present, many kinds of new transportation systems have been developing and some were used as practical urban traffic systems in Japan. But, these developments are not necessarily contributed to the solution of urban traffic problems. Therefore, this research and study that aim to grasp the characteristics and the adaptability of new transportation systems and to evaluate the suitability of these system applications quantitatively have been started. We show the evaluation of suitableness of transportation system applications to the model routes by AHP (Analytical Hierarchy Process). Moreover, by using the same technologies, changes in traffic demand and in transportation share ratio are calculated when a new system is introduced into a region already being served by other systems.

GENERALLY SPEAKING, IT IS DIFFICULT TO INTRODUCE A SUBWAY IN A MIDDLE-SIZED CITY IN JAPAN DUE TO THE INSUFFICIENT DEMAND FOR SUCH A SYSTEM. THIS PAPER CONTAINS THREE DISCUSSIONS. THE FIRST IS AN APPRAISAL OF ELEVEN URBAN TRANSIT SYSTEM IN JAPAN, EXCLUDING THE SUBWAY, IN TERMS OF CONSTRUCTION COST AND PROFITABILITY. THE SECOND DISCUSSION FOCUSES ON THE RESULTS OF A COMPARATIVE ANALYSIS DONE ON A CASE STUDY BASIS OF THREE TYPES OF TRANSIT SYSTEMS IN SENDAI CITY. THESE INCLUDE RENOVATION OF AN EXISTING RAILWAY SYSTEM, A GUIDEWAY BUS SYSTEM AND AN URBAN TYPE OF ROPEWAY SYSTEM. FINALLY, AN INTRODUCTION CRITERIA OF URBAN TRANSIT SYSTEMS FOR A MIDDLE-SIZED CITY HAVING 5,000 PASSENGERS/KM OR LESS IS DISCUSSED FROM A FINANCIAL POAINT OF VIEW.

This paper proposes a model for merging sections in transportation systems and then analyzes traffic flow under this model. For this analysis, vehicles are represented by an idealized model based on a Markov chain model. Vehicles arrive at the merging section randomly in either of two inflow lines. When a vehicle arrives at the merging section, if no vehicle is present in the other line, then the vehicle must wait in order to connect with another vehicle on the other line before entering. In this merging section model, the queue length is restricted according to the travel time from the origin to destination. The mean queue length and mean queuing delay at the two inflow lines are explicitly derived here. The relation between the maximum queue length and the behavior of traffic is examined, and the obtained results clarify some characteristics of the proposed model.

Research and development of new urban transit systems in Japan began with monorails in the 1960s, followed by the development of the so-called “New Urban Transit System” (AGT) in 1970, and the world's first unmanned automatic train operation was put to practical use in Kobe and Osaka in 1981. Automatic train operation was also subsequently introduced and expanded to subway lines.
