Operational Data

This paper assesses the operational data of a public transportation system, using the Bus Rapid Transit in Lagos State as a case study. Demographic data was collected through the administration of questionnaires to the commuters; this was carried out to observe variations in the population of the commuters from different perspectives. Some other categories of data were collected which include boarding and alighting, headway, arrival rate of commuters, waiting time of commuters and travel time data. These data were presented and analysed with MS Excel and Minitab statistical softwares. Results from the boarding and alighting data showed bus stops with high flux of commuters, these were at Ojota, Ketu, Mile 12, Costain, CMS and TBS. Probability distribution charts were prepared to analyze the remaining sets of data. This was carried out to study the distribution and consistency of the data. Coefficients of variation for the data were also estimated to study the variability of the data. From the study, the data followed normal distribution and they were consistent such that they can be used for further analysis of the system. It can be concluded that the distribution depicts the real situation at the study location. Thus, bus stops with high density of commuters should be provided with more buses so as to reduce the waiting time of commuters.

Project Management System

The aim of this paper is to establish an international framework for sustainable project management in engineering, to make up the lack of research in this field, and to propose a scientific theoretical basis for the establishment of a new project management system. The article adopts literature review, mathematical programming algorithm and case study as the research method. The literature review applied the visual clustering research method and analyzed the results of 21-year research in this field. As a result, the project management system was found to have defects and deficiencies. A mathematical model was established to analyze the composition and elements of the optimized international project management system. The case study research selected large bridges for analysis and verified the superiority and practicability of the theoretical system. Thus, the goal of sustainable development of bridges was achieved. The value of this re-search lies in establishing a comprehensive international project management system model; truly integrating sustainable development with project management; providing new research frames and management models to promote the sustainable development of the construction industry.

Ahp Model

To mitigate car traffic problems, the United Nations Human Settlements Programme (UN-Habitat) issued a document that provides guidelines for sustainable development and the promotion of public transport. The efficiency of the policies and strategies needs to be evaluated to improve the performance of public transportation networks. To assess the performance of a public transport network, it is first necessary to select evaluation criteria. Based on existing indicators, this research proposes a public transport criteria matrix that includes the basic public transport infrastructure level, public transport service level, economic benefit level, and sustainable development level. A public transport criteria matrix AHP model is established to assess the performance of public transport networks. The established model selects appropriate evaluation criteria based on existing performance standards. It is applied to study the Stonnington, Bayswater, and Cockburn public transport network, representing a series of land use and transport policy backgrounds. The local public transport authorities can apply the established transport criteria matrix AHP model to monitor the performance of a public transport network and provide guidance for its improvement.

Public Transportation System

The electric bicycle is considered as an environmentally friendly mode, the market share of which is growing fast worldwide. Even in metropolitan areas which have a well-developed public transportation system, the usage of electric bicycles continues to grow. Compared with bicycles, the power transferred from the battery enables users to ride faster and have long-distance trips. However, research on electric bicycle travel behavior is inadequate. This paper proposes a cumulative prospect theory (CPT) framework to describe electric bicycle users’ mode choice behavior. Different from the long-standing use of utility theory, CPT considers travelers’ inconsistent risk attitudes. Six socioeconomic characteristics are chosen to discriminate conservative and adventurous electric bicycle users. Then, a CPT model is established which includes two parts: travel time and travel cost. We calculate the comprehensive cumulative prospect value (CPV) for four transportation modes (electric bicycle, bus, subway and private car) to predict electric bicycle users’ mode choice preference under different travel distance ranges. The model is further validated via survey data.

ResumenEl transporte público y el desplazamiento a pie en las ciudades son elementos clave para el desarrollo sostenible. Distintas ciudades han optado por la implementación de sistemas de transporte público masivo para mejorar la movilidad y promover un desarrollo sostenible. Diversos autores han hablado de la importancia de la marcha a pie como parte de los viajes en transporte público. Los radios de cobertura de las estaciones de metro en distintas ocasiones podrían considerar un aumento del desplazamiento a pie. La investigación se centra en aumentar la caminabilidad alrededor de las estaciones de metro en Quito, de manera que, el caminar puede cumplir una función de co-modalidad para el transporte público. A partir del análisis de la accesibilidad, la densidad y la diversidad de usos se propone una metodología que permite demostrar la validez de las variables seleccionadas para fomentar la caminabilidad en un punto de conexión con transporte público en un entorno urbano en su mayor parte consolidado.AbstractPublic transportation and pedestrian movement in cities are key elements for sustainable development. Different cities have opted for the implementation of massive public transport systems to improve mobility and promote sustainable development. Several authors have talked about the importance of pedestrian movement as part of public transport trips. The investigation focuses on increasing the walkability around the stations of metro in Quito in order to promote walking as a function of co-modality for public transport. A methodology is proposed to demonstrate the validity of the selected variables to promote walkability at a point of connection with public transport in an urban environment for the most part consolidated.

The Empirical Analysis

This research focus on the influence of the network convergence to the cable TV network enterprises. Based on the literature review, status quo and case study, this research combines the collection of open questionnaires, generalizes the influencing factors of the cable TV networks transformation that involve external and internal factors. The influence of external factors is evaluated by the influence of each factor to the component elements of the model, while that of the internal factors is estimated through that to the enterprises competitive advantage. Therefore, this research establishes the structural equation model, followed by the corresponding hypotheses and tests.

Study Behaviour

Nowadays, delays problem are important issue in preparing schedule for public transportation. It is related to behaviour of passengers, behaviour of transportation means and interaction with traffic. Behaviour of passengers are including: demand patterns of passengers, fare payment and waiting time in station and in-vehicle. Behaviour of transportation means included fleet size and frequency of operation. The most interaction between public transportation and others traffic is in traffic congestion. In this paper, we studies different behaviour of passengers duration operation time in two points: in-station and in-vehicle. They are including: arrival rate of passengers, kinds of fare payment and waiting time. For illustrate behaviour of passengers on delays problem we survey they affects in bus operation. Hence, a case study based on an actual public bus operation in Tehran, Iran is used to demonstrate it.
