The author investigated the status of barrier-free facilities of urban rail transit station in China. Due to the physical factors, the senior and disability population fail to utilize urban traffic facilities, like ordinary persons. Also, children, women of pregnancy, and those who have mobility difficulties, and those who bear heavy loads are also not able to conveniently use urban traffic fac...

In comparison with the other transportation modes, rail rapid transit already enjoys a higher degree of safety as it is designed with the exclusive right of way and the automatic train control and monitoring systems. Nevertheless, rail rapid transit systems are not free from serious accidents, which often led to human injuries and facility damages. The planning of accident prevention and emerge...

In the current situation, the automobile has become the main means of locomotion. It allows traveling long distances, encouraging urban sprawl. To counteract this trend, the train is often proposed as an alternative to the car. Simultaneously, the favoring of urban development around public transport nodes such as railway stations is one of the main issues of the coordination between urban plan...

Modern supply chains are characterized by multiple interactions among individuals and evolving temporal patterns of interaction. The grain handling and transportation system (GHTS) in Canada is a good example of a large modern supply chain. In this paper, we develop an agent-based simulation model of this regional supply chain and use the simulation output to assess the viability of an open rai...

There is ongoing debate over the relative advantages of rail and bus transit investments. Rail critics assert that cities which expand their bus transit systems exhibit better performance than those that expand rail systems. This study examines those claims. It compares public transport performance in U.S. urban areas that expanded rail transit with urban areas that expanded bus transit from th...

Railway transport is a type of transport which is commonly used today. Rail line must be robust due to the heavy structure of the railway vehicles. Components constituting the rail line are very important to prevent the disruption of transportation. In this study, faults are determined by monitoring the rail and fastening components constituting the railway. Test vehicle was used to get experim...
