A better understanding of passenger perceived quality helps urban rail transit managers adopt better strategies to improve the service quality of urban rail transit, which is beneficial to the sustainable development of an urban rail transit system itself and cities. This paper designs a semantic scale to survey passenger perceived quality of urban rail transit. The methodology is selecting specific features of an attribute and then describing the features to present the attribute’s service condition and the rider’s experience. The scale’s options can reduce cognitive steps and hesitation for riders to answer the survey questionnaire. Furthermore, it enables urban rail transit managers to understand passenger perceived quality more visually. After verifying the reliability and validity of the semantic scale, an empirical study was conducted to compare the evaluation results of the proposed semantic scale, Likert, and numeric scales. Compared to the Likert and numeric scales, the evaluation result of the semantic scale is fairer for attributes with homogeneous service conditions over operation periods from the transit agency perspective. Meanwhile, it is more homogeneous for attributes with homogeneous service conditions and is more heterogeneous for attributes with heterogeneous service conditions.

Several Delays

Along with our country, a steady and rapid development of economy, politics and culture, the traffic also got rapid development with the trend. The improvement of people's living standard in our country, more and more frequent transportation also emerged, the requirement for the quality of travel people also put forward higher requirements; Therefore, as a responsible for the daily commuter traffic tools, urban rail transit train delay problem should give our attention. The types of urban rail traffic delay is described in this paper, including the initial delay and joint and several delays, and expounds the time characteristics and spatial characteristics of delays, and the urban rail transit delays was studied, on the single line shows the single delays the transmission of the recursive formula, for the delay of the urban rail transit emergency disposal provides theory basis.

<p>Rail transit is a new form of transportation in the process of modern urban development. It has a far-reaching impact on improving urban traffic environment, relieving urban traffic pressure and improving urban traffic service quality. The rail transit cloud platform is an important part of modern rail transit, and it is also a key factor related to the construction quality of urban rail transit. In this paper, the current situation of construction and application of urban rail transit cloud platform are introduced in detail, and the related standard compilation of urban rail transit cloud platform, achievements in the development and construction process, construction mode, index establishment, acceptance process optimization, cloud operation and maintenance system establishment and other issues are systematically expounded. According to the technical drive and standard compilation of urban rail transit cloud platform, the development of urban rail transit cloud platform is prospected.</p>
