Free-floating carsharing systems (FFCS) have become a new type of urban sustainable mobility, much more flexible than the previous station-based carsharing but limited by on-street parking availability and managed by municipal administrations. Literature on FFCS until now mostly relies on survey-based methodologies and simulations, and little research on FFCS has been devoted to the scientific analysis of real flows using revealed web-based data. This paper contributes to the existing literature with an analysis of FFCS trips using rental data collected directly from operators’ websites, paying special attention to the most frequent trips. The added value of this research is that it provides the first analysis of the more FFCS demanding districts in the city of Madrid. The results showed that the main origin and destinations points were concentrated in low populated and high-income districts that also had good parking availability and connectivity to the public transportation network.

Abstract. Due to increasing human population, the need for quality public transportation has also increased. This study takes stop density, stop layout, and passenger population of those stops into consideration to offer a better regulated public transportation network design that can satisfy the increased demand. In this study, the boarding data is provided by the public transportation department of the city of Antalya, Turkey. Remaining required data was automatically generated using web services and stored in a PostgreSQL database hosted on a cloud server. After visualizing inputs such as bus routes, stop layout, and passenger density on Google Maps and KeplerGL, with the use of the K-Means algorithm, data was clustered to find ”hot” (i.e. attraction) areas on a macro scale. A novel means of connecting hot spots suggested by the outcome of the Genetic Algorithm was developed. To compare the effectiveness of the proposed approach with the existing network, current bus stops were mapped to the new domain. It was observed that a more efficient system was achieved by higher route efficiency and lower transfer counts.

This article presents an analysis and characterization of recent sustainable initiatives developed for the public transportation of Montevideo, Uruguay. In addition, specific analysis and recommendations are proposed for the Parque Rodó neighborhood, based on a survey performed to people that commute to/from that area. The analysis considers the main concepts from related works, evaluating relevant quantitative (coverage, accessibility, affordability, etc.) and qualitative (public finance, integration, comfort and pleasure, etc.) indicators. Three sustainable public transportation initiatives are studied: electric bus, public bicycles, and electric scooters. Results of the analysis for each transportation mode suggest that the first initiatives focus on specific sectors of the population and should be improved in order to extend their accessibility and affordability. In turn, coverage must also be expanded. Regarding the analysis of the Parque Rodó neighborhood, results indicate that people are willing to perform the modal shift to more sustainable transportation modes, but several improvements are needed to improve the quality of service. All these aspects are considered in the proposed guidelines for a sustainable mobility plan in the area and also for suggestions and recommendations formulated to develop and improve sustainable mobility in Montevideo.

Abstract: Yogyakarta has several traditional markets, one of which is Beringharjo. This market has been long established in conjunction with the construction of the Sultan Palace and became the economic center in the city of Yogyakarta. Beringharjo located on Jenderal Ahmad Yani street which is the trade area. The purpose of this study is to investigate and understand the elements of the spatial structure of Yogyakarta which support functions as well as to understand and decipher the links between these elements in creating an environment that supports the function of Beringharjo market. Object of observation is a function of the mass and shape of the building is to be around Beringharjo, pedestrian and vehicle lanes to be around Beringharjo Traditional Market, and the types of public transportation are located around Beringharjo Traditional Market. The method used is the observation, and literature. Figure ground theory is used to analyze the function and mass building around Beringharjo. Linkage theory is used to classify characters based on the function and activity, whereas the comparison between theory building height and street width to analyze the convenience of road space for pedestrians. The results of this study are character functions and activities along Jendral Ahmad Yani street can be divided into three segments, that is opening, core and cover. Based on the distribution of the three segments, figure ground analysis that shows the shape and composition of mass transportation lines shows that the public transportation network, namely the Trans Jogja stop there on the third segment. The existence of Trans Jogja buses as public transportation support functions and activities that take place on Jendral Ahmad Yani street, who also supports the sustainability of activities in Beringharjo.

This chapter assesses the roles played by New York governor Nelson Rockefeller and New York City mayor John Lindsay, as well as William Ronan, in transforming the transportation system. Ronan, Rockefeller, and Lindsay all realized that improving public transportation was critical to strengthening the economy of the city and the region. They were also well aware of the benefits of a Second Avenue subway, since all three of them lived on the Upper East Side. After Lindsay failed to reorganize the transportation agencies, Rockefeller and Ronan developed their own grand vision for the region's transportation network, and in December of 1966, Ronan stepped down from his post as secretary to begin implementing their plan. At the beginning of the state's 1967 legislative session, Rockefeller and Ronan announced their two-pronged approach. First, they proposed integrating the New York City Transit Authority and the Triborough Bridge and Tunnel Authority (TBTA) into the Metropolitan Commuter Transportation Authority (MCTA). In addition, Rockefeller and Ronan would seek voter approval to borrow $2.5 billion that would be dedicated for roadway and public transportation improvements across the state. In 1967, the governor and Ronan obtained the support they needed to transform the transportation network, a feat that Lindsay had not been able to accomplish.

Starting Location

Aiming to facilitate the choice of transport links leading from a starting location to a destination in greater Cairo, we propose in this work a public transportation mobile (android) application to assist users of public transport. The system is a pilot application that considers the public mini-buses network in three areas of Cairo, and builds the database of the mini-bus network verified on the ground. From this database, the transportation network graph consisting of nodes and possible links between them is constructed. Upon request, the system then identifies the series of public transport possible, calculates the shortest path between the two chosen locations, and displays the bus, or series of buses, and the routes to the user, ordered by distance. The specialized algorithm Dijkstra was implemented to find the shortest route.

With the aggravation of the traffic congestion in the city, car owners will have to give up commuting with private cars and take the public transportation instead. The paper uses the replication dynamic mechanism to simulate the learning and adjustment mechanism of the automobile owners commuting mode selection. The evolutionary stable strategy is used to describe the long-term evolution of competition game trend. Finally we simulate equilibrium and stability of an evolution of the game under a payoff imbalance situation. The research shows that a certain proportion of car owners will choose public transit under the pressure of public transport development and heavy traffic, and the proportion will be closely related to the initial conditions and urban transportation development policy.
