In this paper, we explore the potential for a partial integration of private and public transportation as provided by taxi and bus services on the level of individual trips. While these modes are typically separated for economic reasons, in the future with shared Autonomous Vehicles (AVs) providing cheap and efficient transportation services, such distinctions will blur. Consequently, optimization based on real-time data will allow exploiting parallels in demand in a dynamic way, such as the proposed approach in the current work. New operational and pricing strategies will then need to be considered, along with regulatory tools to limit congestion, encourage sharing and provide services in a more sustainable way by utilizing a dynamic landscape of urban transportation. In the current work, we evaluate existing parallels between individual bus and taxi trips in two Asian cities and show how exploiting these synergies could form the basis of achieving some of the above goals in the future.

The objective of this paper is to examine the types of autonomous vehicles already employed in transportation. It exemplifies the segments of transportation which already use autonomous vehicles. This paper gives an insight of the places in the world where autonomous vehicles are put in use. Furthermore, companies such as Volvo, Volkswagen, Airbus and WAYMO have showed their models of driverless vehicles ranging from trucks, buses, shuttles and helicopters. Moreover, the paper provides a description, testing methods, use and features of the each vehicle presented. In short, this paper aims to raise consciousness about the future of not just public transportation but also transportation of any other type such as good's transportation, delivery, vehicles provided for sightseeing, aircrafts etc.

The quality of public transportation services is one of the most important performance indicators of modern urban policies for both planning and implementation aspects. Therefore, along with the size of the city, the significance of appropriate cost evaluation and optimization of all related transportation activities increases as well. One of the most important cost factors for the public transport agencies is naturally the fuel consumption of the vehicles. In this study, the attention is focused on the metropolitan bus transport service. The specific aim is to minimize a significant portion of total fuel utilization that occurs due to the so called deadhead trip or dead mileage, which is defined as the idle distance covered by the vehicle between the garage and the route terminal stops without carrying any passengers. In this study, the results of four mathematical models for minimizing the total deadhead trip distance covered in city bus services of Izmir are presented. The models vary due to the inclusion of garage capacity restrictions or operator distinction for supporting both operational and strategical decisions. All models are applied to the recent bus schedule data, which consist of 293 routes, 1,424 buses and 10 garages, for obtaining the optimal route bus-garage allocations and garage capacities. The results of the Decentralized-Capacitated model, which is appropriate for quick implementation, promise a 7.8% reduction in total dead mileage. While on the other hand, if all garage capacities can be expanded and the bus service is maintained only by one operator as modelled in the Centralized-Uncapacitated case, even a 31.4% improvement is possible in the long term. The environmental gains as well as the financial benefits to be achieved when the solutions are actually implemented, justify the practical contribution of the study.

Autonomous vehicles promise to revolutionize the automobile market, although their implementation could take several decades in which both types of cars will coexist on the streets. We formulate a model for a circular city based on continuous approximations, considering demand surfaces over the city. Numerical results from our model predict direct and indirect effects of connected and autonomous vehicles. Direct effects will be positive for our cities: (a) less street supply is needed to accommodate the traffic; (b) congestion levels decrease: travel costs may decrease by 30%. Some indirect effects will counterbalance these positive effects: (c) a decrease of 20% in the value of travel time can reduce the total cost by a third; (d) induced demand could be as high as 50%, bringing equivalent total costs in the future scenario; (e) the vehicle-kilometers traveled could also affect the future scenario; and (f) increases in city size and urban sprawl. As a conclusion, the implementation of autonomous vehicles could be neutral for the cities regarding travel time costs. City planning agencies still have to promote complementary modes such as active mobility (walking and bicycle), transit (public transportation), and shared mobility (shared autonomous vehicles and mobility as a service).

UberHOP is a commute-focused interpretation of the Uber suite of transportation services, with the goal of reducing personal vehicle commute trips. The service first launched in Seattle, Washington, and Toronto, Ontario, Canada, in December 2015 and expanded to Manila, Philippines, in early 2016. UberHOP is similar to vanpooling with fixed pickup and drop-off locations in the primary commute direction during peak hours, but it leverages Uber’s ridesourcing platform to replace fixed departure schedules with riders matched in real time. This paper reports on an intercept survey (83% response rate) to understand who rode, how they traveled to the pickup location, why they rode, and what modes UberHOP was replacing for all 11 UberHOP routes in Seattle during the morning and evening commute periods. In addition, detailed trip and total rider count data were collected during the survey administration process. The results show that many UberHOP riders made UberHOP their primary form of commute mode. Unlike standard ridesourcing services, UberHOP riders predominantly replaced public transportation modes rather than personal vehicles. UberHOP services were canceled in Seattle in August 2016. However, with larger rider densities per trip, the UberHOP model can be profitable, and it is reasonable to expect that Uber or others will resurrect a similar service in the future.

Over the last decade, there has been increasing discussions about self-driving cars and how most auto-makers are racing to launch these products. However, this discourse is not limited to transportation only, but how such vehicles will affect other industries and specific aspects of our daily lives as future users such as the concept of work while being driven and productivity, entertainment, travel speed, and deliveries. Although these technologies are beneficial, access to these potentials depends on the behaviour of their users. There is a lack of a conceptual model that elucidate the acceptance of people to Self-driving cars. Service on-demand and shared mobility are the most critical factors that will ensure the successful adoption of these cars. This paper presents an analysis of public opinions in Nottingham, UK, through a questionnaire about the future of Autonomous vehicles' ownership and the extent to which they accept the idea of vehicle sharing. Besides, this paper tests two hypotheses. Firstly, (a) people who usually use Public transportation like (taxi, bus, tram, train, carpooling) are likely to share an Autonomous Vehicle in the future. Secondly, (b) people who use Private cars are expected to own an Autonomous Vehicle in the future. To achieve this aim, a combination of statistical methods such as logistic regression has been utilised. Unexpectedly, the study findings suggested that AVs ownership will increase contrary to what is expected, that Autonomous vehicles will reduce ownership. Besides, participants have shown low interest in sharing AVs. Therefore, it is likely that ownership of AVs will increase for several reasons as expressed by the participants such as safety, privacy, personal space, suitability to children and availability. Actions must be taken to promote shared mobility to avoid AVs possession growth. The ownership diminution, in turn, will reduce traffic congestion, energy and transport efficiency, better air quality. That is why analysing the factors that influence the mindset and attitude of people will enable us to understand how to shift from private cars to transport-on-demand, which is a priority rather than promoting the technology.

Public transportation using express bus services are widely used by the public nowadays and many bus companies offer services to major cities as well as providing additional features and facilities to attract passengers. However, the passengers often face a problem in selecting and choosing the bus companies that give the best services for them according to their preferences. The purpose of this study is to identify the best bus transportation services based on MCDM approach using the TOPSIS method. The web application development follows the System Development Life Cycle (SDLC) methodology that contains four phases which are planning, designing, testing and implementing using PHP and MySQL database as tools for development. It enables users who already used the bus services to give the rating and the users who want to use the bus services give their priority for each criterion that they choose either low, high or very high. The web application will generate the result, which is the best bus companies according to TOPSIS rules. The presence of this web application can help the society to choose the best bus services that follow their preferences.

This study was motivated by the case of the disappearance of legal bus services due to their loss in competition with a kind of car services called “Travel” for the corridor of Padang - Pesisir Selatan, West Sumatera, Indonesia. Travel might not legal public transport services, and therefore, in this study is also called un-official public transportation. This study aims to determine the driving attributes for passenger’s satisfaction of un-official public transportation services and to figure out the service attributes that need to be improved according to passengers’ perceptions. Data was collected using random sampling with a total sample of 160 respondents and was analyzed using the Importance Satisfaction Analysis (ISA) method. Quadrant analysis of ISA revealed that the availability of music and air conditioner on-board is not so essential but resulting a higher satisfaction to passengers. Passengers are calling for an improvement of the services by consistently implementing the law against a driver who uses a mobile phone while driving or driving inconsiderately, and improving the courtesy and friendliness of the driver.

This chapter considers the role, importance, and impact of public intellectualism on the future of qualitative research. The chapter argues that the move toward technology and the public dissemination of information via the internet requires a shift in how and what we research with an expressed intention of reaching a broader and nonacademic audience. The chapter considers the relationship between the private and public sphere, and the so-called “bastardization” of intellectualism to explain the role and rise of public intellectualism in qualitative research. By considering issues such as personal subjectivity, accountability, representation, and epistemological privilege, the chapter discusses how public contexts inform qualitative research and, conversely, how qualitative research can inform the public.
