The modeling of effective parameters on public bus passengers’ boarding time prediction

Passengers’ boarding times at bus stops have a great importance to calculate dwell and travel time for scheduling process in public transport operations. However, there are not so much observed boarding times data in the actual bus transport systems and it may cause some prediction problems in scheduling process of public transport operations. For this reason, accurate estimation of the boarding times will ensure correct calculation of dwell and total travel time for bus transport systems. Based on this idea, this study aims to model boarding times of each passengers by evaluating different parameters using two different (statistical and optimization analysis) methods. For this purpose, a comprehensive data collection process was conducted in total seven different cities of Turkey based upon their population. Two new models were developed for boarding time estimation by evaluating various parameters using a multiple Ordinary Least Square (OLS) regression and Artificial Bee Colony (ABC) algorithm as statistical and optimization methods, respectively. Study results showed that modeling of boarding times by considering various parameters is an effective strategy to improve the performance of bus transport systems by using developed two models

Applying the LOT Methodology to a Public Bus Transport Ontology aligned with Transmodel: Challenges and Results

We present an ontology that describes the domain of Public Transport by bus, which is common in cities around the world. This ontology is aligned to Transmodel, a reference model which is available as a UML specification and which was developed to foster interoperability of data about transport systems across Europe. The alignment with this non-ontological resource required the adaptation of the Linked Open Terms (LOT) methodology, which has been used by our team as the methodological framework for the development of many ontologies used for the publication of open city data. The ontology is structured into three main modules: (1) agencies, operators and the lines that they manage, (2) lines, routes, stops and journey patterns, and (3) planned vehicle journeys with their timetables and service calendars. Besides reusing Transmodel concepts, the ontology also reuses common ontology design patterns from GeoSPARQL and the SOSA ontology. As part of the LOT data-driven validation stage, RDF data has been generated taking as input the GTFS feeds (General Transit Feed Specification) provided by the Madrid public bus transport provider (EMT). Mapping rules from structured data sources to RDF were developed using the RDF Mapping Language (RML) to generate RDF data, and queries corresponding to competency questions were tested.

30 years of the transformation of non-urban public transport in Poland’s peripheral areas — what went wrong?

Transport-based social exclusion is currently a serious social problem in Poland, and one which is apparently most severe at the level of the county (Polish powiat) in the south-east of the country, including the Beskid Niski and Bieszczady Mountains. A deeper illustration of this problem requires both observation of changes in the suburban public-transport network and the identification of areas in which this has deteriorated significantly in quantity and quality. The chosen starting point for the research was therefore 1990, as a year in which — on the one hand — the Polish economy was already shifted to the new free-market principles; while — on the other — state PKS (Przedsiębiorstwo Komunikacji Samochodowej) non-urban bus transport enterprises still dominated public transport. The endpoint of the study is then the beginning of 2019 (the author’s research year). The article introduced here seeks to identify and present cartographically the changes affecting the public-transport network in the study area over the last 30 years, as well as to point to possible consequences of these processes. The background of the described changes is also discussed, as are the observed consequences of what is taking place.

Phonecardoperated payphones in buses in Brazil

Payphones were installed in public buses in Brazil. These payphones worked with same phonecards used in tradicional payphones or with specific phonecards produced by telecommunication companies in collaboration with bus transport companies. The objectives of this study were to identify the buses installed with payphones in Brazil, chronology, payphone system, and phonecard type (whether tradicional or specific). The specific phonecards were described. A mobile phone-type payphone working with tradicional phonecards, developed by Telecomunicações da Paraíba S.A. (TELPA; João Pessoa, Paraíba State, Brazil) and installed in 1994 on Rogetur Transporte e Turismo Ltda. transport company buses, is the first consolidate case of a payphone used in a bus in Brazil. Specific phonecards developed by Globalstar, Inc. (Covington, Louisiana, United States of America) in 2000 were used in payphones installed on Viação Itapemirim S.A. and Empresa de Ônibus Nossa Senhora da Penha S.A. transport company buses.

Analysis of public transport demand in the Municipality of Stupnik

Public transport is the backbone of urban mobility, providing people with access to employment, education, trade and daily activities. It provides a special benefit to people who do not own a car and are dependent on well-organized public transport. The paper presents an analysis of the demand for public transport services in the Municipality of Stupnik, otherwise organized in the form of bus transport. The paper presents the methodology used, as well as the obtained results, and the associated discussion and conclusion.

The Relationship between Passengers' Satisfaction of Urban Road Transport Services and Their Sense of Belonging

Passengers' satisfaction of urban road transportation services has been widely researched over the past few decades. However, no study has been conducted to analyze the relationship of the passengers' satisfaction of regular taxi and bus transport services with an external psychological factor. To this end, 100 passengers were randomly recruited to participate in this study. The participants were required to complete three questionnaires to assess their level of belonging and their satisfaction of regular taxi and bus transport services as two prominent urban road transport services. The questionnaire of sense of belonging had 12 items rated on a 5-point Likert Scale. The responses also were rated from “strongly disagree” to “strongly agree”. The respondents were requested to grade 1 to 10 an 18-travel-attribute survey to assess their satisfaction of urban road transport services. The results indicated that passengers were not satisfied with urban road transport services; however, their satisfaction with regular taxi was higher in comparison with bus transport services. The findings also revealed that there was a significant correlation between the passengers' level of belonging and their satisfaction of public transport services.

USEABLE DRIVETRAINS IN CONTEMPORARY BUS TRANSPORT

This paper focuses on introducing new, environmentally friendly types of drivetrains in the field of bus transport. Main goal is to present approximate costs of purchase and cost of operating (especially fuels or electricity) and connected them with real emissions of carbon dioxide for each different technology of drivetrain, including Well-to-Tank and Tank-to-Wheel emissions. The authors are using the Weighted Sum Approach method to determine currently the most suitable drivetrain for urban busses.

Improving the management of the technical condition of passenger park metropolis

The article is to improve the efficiency of urban bus transport by reducing the cost, labor and time to ensure its efficiency. The specialization is determined, expressed in the growing concentration of production, which have a commonality on a certain scale. The link is in the growth of production concentration, manifested in the increase in the size of enterprises. This is due to the development of internal cooperation, and for economic reasons. It is proved that the contradiction between the natural desire for economic dominance, as a way to preserve and increase the benefits, and the requirements of optimality that prevent this, is resolved by combining enterprises.
