A pesquisa tem como objetivo investigar os fatores-chave de sucesso na adoção de aplicativos móveis de táxi (AMTs) por taxistas. Baseando-se nos modelos de Aceitação Tecnológica (DAVIS; BAGOZZI; WARSHAW, 1989), Difusão da Inovação (ROGERS, 1995) e de Confiança (CARTER; BÉLANGER, 2005), o trabalho propõe também uma revisão da literatura de Aplicações Móveis aplicada ao contexto dos AMTs (VAN BILJON; KOTZÉ, 2007). Para o propósito dessa pesquisa, os AMTs são definidos como aplicativos de serviço móvel avançado que viabilizam, por meio de Internet e geolocalização, a solicitação de transporte de táxi em dispositivos móveis, mediante sistemas de informação e chamadas telefônicas, e o acompanhamento da prestação do serviço e seu pagamento. A partir de entrevistas semiestruturadas em profundidade e aplicações de questionários em pesquisa de campo, o estudo propõe uma triangulação de métodos de Análise Lexical (BOTTA,2010; GEERAERTS,2010), Conteúdo (BARDIN,2006) e Ranking Médio (OLIVEIRA,2005) para a investigação dos fatores identificados na literatura. Os resultados apontam que os fatores influenciadores do sucesso dos AMTs, na perspectiva de uso pelos motoristas de táxi, são Simplicidade e Utilidade Percebida...

Executive Summary: Airport terminals curbsides are the critical interfaces between stand- ing vehicles, moving vehicles and pedestrians, acting as the capacity buffer between the road delivery system and the airport terminal building. Their design and capacity are essential to the successful performance of any airport infrastructure and, therefore, impact the quality of passenger experience. The current solution at Portela Airport for taxi service provision on the passengers arrival curbside consists on a set of two parallel lanes next to the door of the airport terminal, with four spots (two in each lane) for taxis to stop and pick up passengers. Its design turns the service of taxis in the same lane strongly linked, leading to the occurrence of blocking effects among taxis, which also reduces the utility of expanding the number of stop areas. A new solution for taxi service provision was recently proposed by Globalvia. The new service configuration consists of a “spine” parking design for 8 taxis at arrivals, and another one at departures with an identical geometry but for private cars. In both cases, the proposed solution consists of a strip parallel to traffic routes, with parking positions arranged at 45 degrees with respect to the road...

This note outlines the progress achieved by the Western Cape Provincial Government to attain formalization of the minibus taxi industry envisaged in terms of the National Taxi Task Team (NTTT) recommendations released in September 1996. The Western Cape departed from the other eight Provinces of South Africa by deciding to commit key elements of the NTTT recommendations to legislation in the Western Cape Road Transportation Act Amendment Law. This action was prompted by the determination of the Provincial Minister of Transport to arrest the violent situation that had characterized the Minibus Taxi Industry up to then. The formation of a Provincial Taxi Working Group (PTWG) backed by this legislation has been an effective means to advance the formalization process in the Western Cape Province. This initiative is currently at its most active, and will continue through the remainder of 1998 and into 1999, until the minibus taxi industry has been fully regulated. Training and economic restructuring measures are also being provided according to the NTTT recommendations.

Taxis perform an important function in urban transport markets in both developed and developing countries. Because of the perceived vulnerability of passengers to exploitation by operators, entry to the market and fares have been tightly regulated in many industrialized countries. This has typically produced high premium values for licenses, implying some monopoly profit for operators at the expense of users. Curiously, however, total deregulation has often increased fares. This note considers the reasons for increased fares despite deregulation, the regulatory options available, and the relevant considerations in applying this experience to developing countries.

It is in this context that this study has been undertaken to document BRT case studies in terms of the political setting, institutions/governance, public involvement and communications, service/operations/management and planning and their relationship to investment performance. The study has been undertaken in recognition of the fact that successful implementation and operation of BRT systems often reflects non-physical actors like leadership, communications, organizational structure, service planning and operating practices rather than the design of transitways, stations, terminals and vehicles. This paper does not seek to compare BRT with other forms of public transport but only seeks to evaluate a sample of BRT systems in terms of the softer issues that have contributed making a BRT system successful or not so successful.

A decline in organized public transport systems has led to rapid growth in non-conventional means of public transport, initially provided by minibuses and shared taxi/vans, and more recently by commercial motorcycles. Unlike cities in South and East Asia, ownership and use of motorized two-wheelers as a personalized vehicle is very small in sub-Saharan cities. However, over the past decade there has been a significant growth in the use of motorcycles as a commercial public transport mode. While offering certain transport advantages in the form of easy maneuverability, ability to travel on poor roads, and demand responsiveness, commercial motorcycle service growth has also led to an increase in road accidents, traffic management problems, pervasive noise and increases in local air pollution and greenhouse gas emissions. Government efforts to regulate the market have had the contrary impact of compounding the problem by distorting market structures. The growth in the use of commercial motorcycles has also dispelled one of the commonly held illusions: fare controls in the public bus market are often justified to support affordability for a vast majority of low income population; however...

The population of Senegal is about 12 million. Over 3 million people live in the Dakar metropolitan region, which is growing at twice the pace of the country as a whole (the population growth rate of Dakar is about 3.6 percent per year compared with the national rate of 2.2 percent per year). As in most cities in developing countries, authorities have found it difficult to meet the service demands of the growing population, particularly those of the poor, who are the most dependent on the public provision of water, electricity, transport, and other services. The objective of this study is to (1) establish how effective the finance scheme has been in improving the quality of urban transport services in Dakar since its implementation in 2005; (2) examine whether the approach is proving to be financially self-sustaining and what effect the introduction of new vehicles is having on other service providers; and (3) determine whether, on the basis of the available evidence, the scheme offers a sustainable approach (both operationally and financially) to improving transport service provision in other Sub-Saharan Africa (SSA) cities. The program is not designed to increase public transport capacity...

The Norwegian Social Science Research Institute (FAFO) in conjunction with field based teams in five Middle East and North Africa (MNA) region countries worked under the guidance of the World Bank to organize, design and implement a Service Delivery Survey (SDS) spanning the period 2005-61. The SDS diagnostic examines the linkages between government policies and service delivery performance. The aim of the exercise was to provide an end-user perspective on potential ways of improving service quality, cost and outreach outcomes. It builds upon the institutional and policy review carried out in the MNA-8 countries by the World Bank in 2004 and uses the body of knowledge generated as a basis for refining the service delivery analysis in several ways. First, by surveying end-users it assesses their perception of the quality and coverage of services, improvements that they have noted, and the deficiencies that still exist. Second, it gauges their understanding of the service delivery mechanism, i.e. whether the users feel private sector providers...

The World Bank's study covered all modes of city and inter-city land transport, also designated in this report under the name of 'road transport'. However, the report focuses on the Governments two main concerns: the urban bus and taxi sector, which performs poorly and is a major cause of the growing traffic congestion in Yemeni cities, particularly in Sana'a; and the inter-city freight sector, which does not presently develop in ways that adequately serve the economy. Sana'a is indeed a large and fast growing city where public transport has become critical. Its population was 1.75 million in 2004, while forecasts are for 2.8 million for 2014 and 3.8 million for 2024. Yet, Sana'a's public transport system performs poorly. Similarly, the efficiency of inter-city freight transport is low and it does not promote trade, competition, and low price of basic commodities as it should. In addition, Yemen faces a very high rate of road accidents: in 2006, the number of recorded accidents was about 13,000, resulting in about 2...

The global restructuring of production has led to increasingly precarious working conditions around the world. Post-industrial work is characterized by poor working conditions, low wages, a lack of social protection and political representation and little job security. Unregulated forms of work that are defined as “irregular” or “illegal”, or in some cases “criminal,” are connected to sweeping transformations within the broader regulated (formal) economy. The connection between the formal and informal sectors can more accurately be described as co-optation and, as a subordinate integration of the informal to the formal. The city of St. Catharines within Niagara, along with much of Ontario’s industrial heartland, has been hard hit by deindustrialization. The rise of this illegal service is thus viewed against the backdrop of heavy economic restructuring, as opportunities for work in the manufacturing sector have become sparse. In addition, this research also explores the paradoxical co-optation of the growing illicit taxi economy and consequences for racialized and foreign credentialed labour in the taxi industry. The overall objective of this research is to explore the illicit cab industry as not only inseparable from the formal economy...

According to U.S. government surveys, 12% of Americans used taxi service in the previous month' and spent about $3.7 billion a year for cab fare.2 Taxi service is one of the major modes of public transportation. Despite providing services 24 hours a day, driving relentlessly with an empty taxicab in search of passengers and answering dispatch calls instantaneously, taxi service is ranked the most unsatisfactory mode of transportation by the public. Charging higher fares than other major modes of transportation and averaging 10 to 12 hours work day, taxi drivers have a difficult time to earn a sustainable income.Approximately half of all the taxi mileage is paid mileage; this means a significant portion of a taxi's time and fuel is spent on non-revenue generating activities, i.e. without passengers. Current taxi allocation is inefficient. The number of taxis and the geographical service areas which they serve are heavily regulated in most cities. With limited competition and strict regulations, taxi service suffers with customers having to endure long wait times and inferior services. The current taxi systems in most U.S. cities may be greatly improved from their current state.; (cont.) This thesis investigates the factors of inefficiency in the current taxi system...

The rise of Uber as the global alternative taxi operator has attracted a lot of interest recently. Aside from the media headlines which discuss the new phenomenon, e.g. on how it has disrupted the traditional transportation industry, policy makers, economists, citizens and scientists have engaged in a discussion that is centred around the means to integrate the new generation of the sharing economy services in urban ecosystems. In this work, we aim to shed new light on the discussion, by taking advantage of a publicly available longitudinal dataset that describes the mobility of yellow taxis in New York City. In addition to movement, this data contains information on the fares paid by the taxi customers for each trip. As a result we are given the opportunity to provide a first head to head comparison between the iconic yellow taxi and its modern competitor, Uber, in one of the world's largest metropolitan centres. We identify situations when Uber X, the cheapest version of the Uber taxi service, tends to be more expensive than yellow taxis for the same journey. We also demonstrate how Uber's economic model effectively takes advantage of well known patterns in human movement. Finally, we take our analysis a step further by proposing a new mobile application that compares taxi prices in the city to facilitate traveller's taxi choices...

Taxi services are a vital part of urban transportation, and a considerable contributor to traffic congestion and air pollution causing substantial adverse effects on human health. Sharing taxi trips is a possible way of reducing the negative impact of taxi services on cities, but this comes at the expense of passenger discomfort quantifiable in terms of a longer travel time. Due to computational challenges, taxi sharing has traditionally been approached on small scales, such as within airport perimeters, or with dynamical ad-hoc heuristics. However, a mathematical framework for the systematic understanding of the tradeoff between collective benefits of sharing and individual passenger discomfort is lacking. Here we introduce the notion of shareability network which allows us to model the collective benefits of sharing as a function of passenger inconvenience, and to efficiently compute optimal sharing strategies on massive datasets. We apply this framework to a dataset of millions of taxi trips taken in New York City, showing that with increasing but still relatively low passenger discomfort, cumulative trip length can be cut by 40% or more. This benefit comes with reductions in service cost, emissions, and with split fares, hinting towards a wide passenger acceptance of such a shared service. Simulation of a realistic online system demonstrates the feasibility of a shareable taxi service in New York City. Shareability as a function of trip density saturates fast...

Empty taxi cruising represents a wastage of resources in the context of urban taxi services. In this work, we seek to minimize such wastage. An analysis of a large trace of taxi operations reveals that the services' inefficiency is caused by drivers' greedy cruising behavior. We model the existing system as a continuous time Markov chain. To address the problem, we propose that each taxi be equipped with an intelligent agent that will guide the driver when cruising for passengers. Then, drawing from AI literature on multiagent planning, we explore two possible ways to compute such guidance. The first formulation assumes fully cooperative drivers. This allows us, in principle, to compute systemwide optimal cruising policy. This is modeled as a Markov decision process. The second formulation assumes rational drivers, seeking to maximize their own profit. This is modeled as a stochastic congestion game, a specialization of stochastic games. Nash equilibrium policy is proposed as the solution to the game, where no driver has the incentive to singly deviate from it. Empirical result shows that both formulations improve the efficiency of the service significantly.; Comment: Appears in Proceedings of the Twenty-Eighth Conference on Uncertainty in Artificial Intelligence (UAI2012)

published and funded by the Delaware Center for Transportation; As one of the most rapidly “graying” states in the nation, Delaware soon will be faced with significant growth in the demand for public transportation services that meet the needs of an increasingly older population. This population, moreover, is more likely to require assistance due to one or more disabilities that may affect individuals’ ability to go outside their homes. Coupled with an ongoing shift of the state’s population from the more urban north to the more rural south and a growing desire among older adults to “age in place” if at all possible, the impact this “graying” phenomenon on the state’s already burdened paratransit bus system will become unmanageable unless programmatic changes are implemented. The purpose of this report is to explore the efficacy of raising Delaware’s taxi industry from its current balkanized status to a level of accessibility and performance that will permit it to augment the state’s traditional public transit services. The report’s title employs the phrase “optimizing accessible taxi service” but, as quickly became clear in the process of inventorying the nature and extent of existing services, the term truly understates the magnitude of the change that is required. In Delaware...
