The proposed system is an automatic-taxi, public-transport service for towns and cities, capable of 10 000 passengers per hour per track and aimed to be competitive with the private car. Mini-sized cars are used which carry up to four adult passengers, using induction-motor drives powered from an overhead rail. The cars are driverless and route themselves at 35 mile/h to their destination with no stops at intermediate stations, though they are slowed down when changing to another line. The cars move along a light-weight totally-enclosed track of less than 7 ft diameter, which can be supported above existing roadways or buildings. The total capital cost is of the order of λ400,000 per single-track mile and the total operational cost 1 d. to 2 d. per passenger mile. A complete system for a town of 400 000 inhabitants, involving 100 single-track miles, would cost from λ30 million to λ40 million.

: Public transport accessibility (PTA) is an essential index for evaluating the efficiency of urban public transport resource and public service. Improving public transport accessibility is considered as the most effective way of alleviating urban congestion and promoting urban sustainability. PTA can be divided into three types, which are access to stations, accessibility of networks and access to activities. This paper focuses on evaluating access to public transport service at stations, considering walking time to stations and waiting time for services at stations. Numerous studies have been carried out on evaluating the accessibility of public transport stations. When building accessibility evaluation model, rare has seen different public transport modes as an integrated system. Hence the topological structure and geometrical layout of the system are not considered. In this paper, factors like the configuration of the public transport system and the surrounding environment of stations are included for the evaluation. The centrality of station index (COS) is presented to describe the importance of stations in the integrated public transport system. The COS index is an improved combination of the gravity model and degree centrality index of the complex network. This index improves the degree centrality index by replacing the number of nodes with weighted connections between stations. By modeling public transport operation, configuration and surroundings of stations, a comprehensive public transport service accessibility index (CPTAI) is formulated to quantify accessibility at the community level. To compute this index, a network analysis model is firstly applied to find the nearest station for each point of interest (POI) by using ArcGIS desktop 10.2, and the transport service frequency at the nearest station is measured. Then Baidu Map API is employed to measure the impedance indexes between stations in the integrated public transport network. Activities covered by stations within a given distance are seen as the generation and attraction of trips in between the stations. Then a weighted gravity model and COS is presented to calculate the integrated service frequency (ISF) for each POI afterward. In the end, the index is converted to the community level, which is CPTAI. The experiment is carried out in Wuhan metropolitan area, Hubei, China. Smart card data (SCD) is utilized to evaluate CPTAI and examine the association between commuting trips by public transport and accessibility level within Wuhan metropolitan area. Experimental results show that CPTAI has a significant statistical association with trips by public transport.

RESUMENEl estudio, que se basa en una encuesta presencial aplicada a una muestra aleatoria cada año, muestra la evolución entre los años 2007 y 2014 en la calificación que le asignan las personas vulnerables al transporte público de Santiago, los beneficios y consecuencias negativas que les ha traído el Transantiago (sistema integrado de transporte público implementado en febrero de 2007 en Santiago), nivel de reclamos efectuados y respuesta obtenida, además de la calificación a diferentes atributos de este sistema como seguridad frente a asaltos, nivel de ruido en los buses, tiempos de viaje, seguridad frente a accidentes y precio del servicio, entre otros resultados.Palabras clave: nivel de satisfacción, transporte público, Transantiago, pobreza.Changes in satisfaction level of vulnerable people from Santiago de Chile respect to Transantiago, years 2007-2014ABSTRACTThis study based in an annual survey to random samples shows the evolution between 2007 and 2014 in the rating given by vulnerable people living in Santiago to the public transport service,benefits and negative consequences Transantiago (integrated public transport system implementedin February 2007 in Santiago) represent for them, claims submitted and responses received. It also contains a qualification of different attributes of this system, as security against assaults, noise, traveltimes, security against accidents and service price, among others.Keywords: satisfaction, public transport, Transantiago, poverty.Evolução no nível de satisfação das pessoas vulneráveis de Santiago do Chile com o Transantiago entre os anos 2007-2014RESUMOO estudo, que é baseado num inquérito presencial aplicada numa amostra aleatória cada ano, mostra a evolução entre os anos 2007 e 2014 na qualificação atribuída pelas pessoas vulneráveis ao transporte público de Santiago, os benefícios e as consequências negativas que lhes trouxe o Transantiago(sistema integrado de transportes públicos implementada em fevereiro de 2007, em Santiago), nível de reclamos realizados e resposta obtida, além da qualificação para diferentes atributos deste sistemata is como a segurança contra os assaltos, nível do ruído nos ônibus, tempos das viagens, segurançacontra acidentes e custo do serviço, entre outros resultados.Palavras-chave: nível de satisfação, transporte público, Transantiago, pobreza.

Abstract In Western countries, the new visions are applied in quality control for an integrated public transport system. Public transport puts the customer at the centre of our decision making in achieving customer satisfaction with provided service. Sustainable surveys are kept among customers. A lot of companies are collecting huge databases containing over 30,000 voices of customers, which demonstrates the current satisfaction levels across the public transport service. Customer satisfaction with a provided service is a difficult task. In this service, the quality criteria are not clearly defined, and it is therefore difficult to define customer satisfaction. The paper introduces a possibility of CSI index application in conditions of the Slovak Republic transport area.
