This study quantifies the impact of individual attributes, built environment, and travel characteristics on use bike-sharing willingness shifting to bike-sharing-related modes (bike-sharing combined with other public transportation such as bus subway) under different scenarios. The data are from an RP (Revealed Preference) survey SP (Stated in Nanjing, China. Three mixed logit models established: attribute–travel model, a various-factor usage frequency scenario–transfer model. It is found...

This paper examines a new evaluation of urban road traffic safety based on matter element analysis, avoiding the difficulties found in other evaluations. The issue has been investigated through analysis theory. chief aim present work is to investigate features safety. Emphasis was placed construction criterion function by which achieved hierarchical system objectives be evaluated. theory used create comprehensive appraisal model technique employ newly developed and versatile algorithm....

Disruptive events cause decreased functionality of transportation infrastructures and enormous financial losses. An effective way to reduce the effects negative consequences is establish an optimal restoration plan, which recognized as a method for resilience enhancement risk reduction in system. This study takes total travel time measure formulate bilevel optimization model given scenario. However, uncertainties involved activities cannot be overlooked. In this context, inherent uncertainty...

Road traffic carbon dioxide emissions have a significant impact on the atmospheric environment, and changes in conditions can affect these emissions; while state infarction reflect conditions, there are also differences generated by vehicles operating different fuels. Therefore, this paper sequentially determines quantitative indicators of states as well macro control strategies to improve emissions. Furthermore, taking confluence area object analysis, is analysed with actual flow data...

With the rise of sharing economy, shared bicycles have become an important component urban transportation. This paper explores nonlinear dual oligopoly system for Cournot model in bike-sharing market; both operators maximized profits as their competitive goals. The analysis pivotal factors influencing passenger preferences, including pricing discounts and comfort levels, is meticulously depicted by a bifurcation diagram. A new chaotic attractor—the bicycle attractor—is discovered. research...

Abstract In this paper, the least square support vector machine (LSSVM) is used to study safety of a high-speed railway. According principle LSSVM regression prediction, parameters are optimized model natural disaster early warning safe operation railway, and management measures methods railway under disasters given. The relevant statistical data China's for training verification. experimental results show that can well reflect nonlinear relationship between accident rate influencing...

This paper identifies salient beliefs that influence e-bike couriers’ traffic violation behavior based on the theory of planned (TPB). Two surveys were conducted in Nanjing, China, 2018. The first survey extracted key psychological beliefs, which used to design a questionnaire. second assessed TPB components and reported behavior. A structural equation model was adopted analyze data. results revealed attitudes, descriptive norms, perceived behavioral control explained 55.7% variance...

In order to rationally evaluate the high speed railway operation safety level, environmental evaluation index system of should be well established by means analyzing impact mechanism severe weather such as raining, thundering, lightning, earthquake, winding, and snowing. addition that, attribute recognition will identified determine similarity between samples their corresponding classes on multidimensional space, which is basis Mahalanobis distance measurement function in terms with...

The aim of this paper is to propose an attribute recognition model, so that it can be used simultaneously estimate the public transit network system. Based on analysis a variety factors influencing network, quantitative research has been conducted with reference theory in order make scientific decision‐making. On basis defining measure, presents model suggesting evaluate network. reliability new method explained using real data survey China. applied results offer for instructing and...

Aiming to solve the safety problems of high-speed railway operation and management, one new method is urgently needed construct on basis rough set theory uncertainty measurement theory. The should carefully consider every factor that realizes indexes its operation. After analyzing factors influence in detail, a model finally constructed describe process. Based above considerations, this paper redistricts as 16 which include staff index, vehicle equipment index environment. And also provides...

Abstract To address the shortcomings in decision-making methods for ground motion threshold warning models high-speed rail earthquake early systems (HSREEWs), we propose a dual judgement method and corresponding process decisions based on joint peak acceleration (PGA) complex environmental risk evaluation (ERE) values. First, analyse characteristics of four environments (HSR) operating environments. Second, establish an index system adversarial interpretive structure modelling method-based...

Trip mode split is the result of interrelated and mutually independent factors, such as city scale, urban form, economic level, trip distance, travel time. In order to analyze formation traffic structure, it necessary make a comprehensive study on mechanism these factors obtain basic causal relationship them. Based this, by using hierarchical structure model in system engineering, this paper firstly clarifies logical different factors. Then, existing survey data several cities used establish...

The primary objective of this study is to analyze the characteristics commuting activities within historical districts in cities China. impacts various explanatory variables on commuters’ travels are evaluated using structural equation modeling (SEM) approach. household survey was conducted Yangzhou, Based data, individual and attributes were considered exogenous variables, while subsistence activity characteristics, travel times, numbers three typical home-based trip chains, mode as...

The aim of this paper was to study the floating car data (FCD) application from origin destination (OD) estimation issues. Thus put forward a method estimate OD matrix based on FCD. In study, we first propose model for obtaining prior Then bi-level programming designed flow estimation. As mentioned above bi- level is multi-objective optimization model, and second which integrated into model. time-dependent traffic assignment Two-stages genetic algorithm were used solving At last, apply test...

Pedestrian injuries and fatalities present a problem all over the world. conformity violation behaviors, which lead to many pedestrian crashes, are common phenomena at signalized intersections in China. The concepts metrics of complex networks applied analyze structural characteristics evolution rules network about crossings. First, pedestrians crossing street is established, network's degree distributions analyzed. Then, by using basic idea SI model, spreading model illegal behavior...

On the basis of setting up evaluation standard safety levels, it adopts membership function and gets quantized index traffic expressway. In this paper, rating each alternative is described by interval numbers. According to concept TOPSIS, a closeness coefficient defined determine ranking order all alternatives calculating distances both ideal solution anti-ideal solution.
