Mobile interfaces need to allow the user and system to adapt their choice of communication modes according to user preferences, the task at hand, and the physical and social environment. We describe a multimodal application architecture which combines finite-state multimodal language processing, a speech-act based multimodal dialogue manager, dynamic multimodal output generation, and user-tailo...

A large quantity of failure data for subway vehicles was collected from long-term field investigations and technical exchanged. These failure data has a guiding significance for preserving subway system. By preprocessing (screening, refining, and classification) the original data and statistical analysis, we establish some selected model, then we use A-D test to verify the degree of fitting in ...

Abstract At present, PWM rectifier is widely used in various high power and voltage situations because of its energy, low harmonic content, constant bidirectional energy. The energy supply system subway traction based on shows the topology a dual transformer with three winding transformers four rectifiers parallel, which superior to modular model. Finally, correctness control strategy verified ...

We investigate the effects of mobile-sourced ridesharing via platforms like Uber, Lyft, and Didi Chuxing on the use of public transit systems. Our study uses trip-level data about Uber usage in New York City, turnstile data about subway usage, and trip-level data about taxicab and shared bike usage. We find that on the surface, ridesharing and subway usage are positively correlated. Exploiting ...

In this paper, we investigate how to increase the capacity of GSM (Global System for Mobile communications) radio interfaces in subway tunnel environments by means of antenna arrays and Space–Time (ST) receivers. We address the modeling, both theoretically and experimentally, of the multiple-antenna wireless channels encountered in subway tunnels. We demonstrate that propagation is conveniently...

Today, urban transportation has attracted urban planners’ and researchers' attention because of air and noise pollution problems associated with it. In Shahrkord city in Iran, no plans have been made for sustainable transportation, and the available poor transportation infrastructure is not responsive to the growing population of the city. This issue has inflicted the city with serious problems...

This exploratory paper attempts to understand some challenges for older tourists regarding the physical accessibility of public transport. It focuses on Mexico City and its global competitiveness as an accessible tourism destination. A review recent literature internet sources contributed raising potential involved offer transport service in City. Sources reviewed suggest that two modes transpo...

In 2011, Boston became one of the first cities in the United States to launch a bike-sharing program. Because public transportation by bus and subway can be slow in Boston, and driving even worse at times, bikes were thought to be a good alternative. One of the fun parts about taking public transportation is seeing who will be riding with you. Oftentimes you’ll learn more about some topic just ...

Beijing lies on the northeastern margin of the North China Plain. The spatial organization of this city is characterized by the continuous addition of ring roads. Today Beijing has five rings completed for public use. The first ring circles the Forbidden City (the palace of the emperors). Because the area has no dense residential areas and few employees, the ring does not carry heavy regional t...

car-following models, as the most popular microscopic traffic flow modeling, is increasingly being used by transportation experts to evaluate new intelligent transportation system (its) applications. a number of factors including individual differences of age, gender, and risk-taking behavior, have been found to influence car-following behavior. this paper presents a novel idea to calculate the...
