Chain Theory

Traveling by bus brings many benefits to passengers. However, the growth of passengers using the bus as a means of transport remains slower than that of population and private transportation. This places a strong pressure on urban traffic in Ho Chi Minh City (HCMC). This study aims to explore the attributes of the bus system in HCMC, affecting various values that prevent passengers from using the bus. The study employs the Means-end chain theory as the frame and soft-laddering interview to collect data. Data collected from 36 interviewees, including 25 passengers and 11 experts, is analyzed by Association Pattern Technique (APT) and presented in a Hierarchical Value Map (HVM). The findings show that there are 18 attributes, 27 consequences, and seven individual values preventing passengers from traveling by bus in HCMC. Six key attributes are identified, including not convenient and far bus stations, many stops during the trip, not accurate schedule as planned, ticket collector’s poor behaviors, too many passengers on a bus, thief, or sexual harassment. These attributes lead to a negative impact on key (individual) values, such as Safety, Time control, Health problem, Convenience, and Respectfulness. From these findings, some suggestions are proposed to improve the frequency of bus using in HCMC.

Light rail transit systems (LRTs) are attractive options for modern communities as they offer high quality, sustainable public transportation services. However, investment costs often may make their application for medium-sized cities prohibitive, particularly if no significant social benefits are achieved. Guided light transit (GLT) has been introduced in the recent years, as a lower cost alternative to LRT, with the additional advantage of being suitable for urban environments with space limitations. In this study, a systematic comparison of LRT and GLT is offered, in the context of a mid-size city in Greece. Results indicate that high investment costs, coupled with low ridership can have a negative impact to the introduction of LRT in a medium-sized city. However, under certain conditions, GLT may be a viable alternative, while its nature and characteristics are not that different to those of LRT.

Abstract. The enormous increase in the number of vehicles in the cities makes plenty of problems including air pollution, noise pollution, and traffic jam. Overcoming these annoying issues needs a significant plan in urban management such as using modern techniques in public transportation systems. Sharing either cars or taxies is one of the most interesting ways that has been used in some countries recently. In this phenomenon, 2 or 3 people use other’s car or taxi. In this article, an innovative approach to share taxies is proposed, and it uses a Genetic Algorithm to determine the placement of travelers in taxies. Therefore, some taxis will be switched off, and this helps to decrease urban traffic jam in cities. The results present that the proposed model turns off 69.8 % of taxies, and also 27.8 % of them carry more than one passenger; hence, this confirms the performance of the proposed model.

Level Of Satisfaction

Due to the policy of the Doi moi in Vietnam started in 1986, Hanoi has undergone many important changes. Currently, Hanoi's traffic is characterized by seemingly continuous motorcycle flows - a representative of high personal mobility in the context of rising incomes. Congestion, dust, pollution, insecurity, overload, etc., they are important keywords to describe Hanoi's urban traffic. Hanoi has put in place a number of policies to improve the transportation system. In 2017, in Hanoi's new mobility improvement project, there is a regulation on motorcycles: “The municipality will zone by limiting the activities of motorcycles according to the infrastructure and the service capacity of the public transportation system to stop motorcycle activities in the central districts in 2030” that becomes controversial. This article, based on the results of surveys assessing the level of satisfaction and desires of people about traffic at the KDTMs of Hanoi, analyzes the differences between the wishes of the municipality and the practices of Hanoi, through habits, modes of mobility of KDTM residents - the new residential areas of Hanoi that bring a different atmosphere of habitat compared to existing neighborhoods, by changing the mode of (re)making of the city. How will the traffic of KDTM residents be affected by this decision as well as how KDTMs will participate in the sustainable transportation of Hanoi?. It is the KDTMs with their “novelties” that will have to become pioneers creating opportunities of the changing of Hanoi traffic.

IntroductionExposure to secondhand aerosol from e-cigarette (SHA) may pose harmful effects to bystanders. This study aims to investigate the prevalence, duration and determinants of SHA exposure in various indoor settings in 12 European countries.MethodsIn 2017–2018, we conducted a cross-sectional study, the TackSHS survey, on a representative sample of the population aged ≥15 years in 12 European countries (Bulgaria, England, France, Germany, Greece, Ireland, Italy, Latvia, Poland, Portugal, Romania and Spain). We described the prevalence and duration of exposure to SHA in several indoor settings among 11 604 e-cigarette non-users. Individual-level and country-level characteristics associated with SHA exposure were also explored using multilevel logistic regression analyses.ResultsOverall, 16.0% of e-cigarette non-users were exposed to SHA in any indoor setting at least weekly, ranging from 4.3% in Spain to 29.6% in England. The median duration of SHA exposure among those who were exposed was 43 min/day. ‘Other indoor settings’ (eg, bar and restaurant) was reported as the place where most of e-cigarette non-users were exposed (8.3%), followed by workplace/educational venues (6.4%), home (5.8%), public transportation (3.5%) and private transportation (2.7%). SHA exposure was more likely to occur in certain groups of non-users: men, younger age groups, those with higher level of education, e-cigarette past users, current smokers, those perceiving SHA harmless and living in countries with a higher e-cigarette use prevalence.ConclusionsWe found inequalities of SHA exposure across and within European countries. Governments should consider extending their tobacco smoke-free legislation to e-cigarettes to protect bystanders, particularly vulnerable populations such as young people.Trial registration numberNCT02928536.

The City

Tram system is a backbone of public transportation in the City of Zagreb. In the last decade, its fleet has been renewed by 142 new low-floor trams. Shortly after their introduction, it was observed that they have a negative impact on the exploitation behavior of tram infrastructure, primarily on the durability of rail fastening systems. Because of that, it was decided to modify existing rail fastening systems to the new track exploitation conditions. When the (re)construction of tram infrastructure is carried out by applying new systems and technologies, it is necessary to take into account their impact on the future propagation of noise and vibration in the environment. This paper gives a short overview of the characteristics of the two newly developed rail fastening systems for Zagreb tram tracks, their application in construction of experimental track section, and performance and comparison of noise and vibration measurements results. Measured data on track vibrations and noise occurring during passage of the tram vehicles is analyzed in terms of track decay rates and equivalent noise levels of passing referent vehicle. Vibroacoustic performance of new fastening systems is evaluated and compared to referent fastening system, in order to investigate their ability to absorb vibration energy induced by tram operation and to reduce noise emission.

In facing the challenges of urban traffic congestion, when people are becoming more dependent on private vehicles, public transportation services should be functioning effectively as attractive alternative modes. This research evaluates how rail public transport users perceive day to day quality of the provided services. The study investigates commuters‟ satisfaction levels of various trip making aspects on board KTM Komuter trains, a commuter services operated by the company Keretapi Tanah Melayu Berhad (KTMB), a heavy rail operator in Kuala Lumpur, Malaysia. A systematic probabilistic sampling questionnaire survey was conducted among the users during the month of December 2011 until March 2012. A sample of 1000 questionnaire forms returned by respondents have been gathered for purposes of ascertaining the overall satisfaction level and analysis on selected aspects of the performance indicators. The results have shown that the majority of the respondents perceived KTM Komuter services to be below the levels that the users had expected, especially the non-adherence to published schedule and travel times, frequency or headways, capacity, the physical conditions of the rail coaches and the information on delays. Most of them expected better services to increase their satisfaction levels. Hence, it is concluded that for the rail public transportation to be sustainable and continuously relevant, the operator has to increase KTM Komuter‟s effectiveness and efficiency or the services have to in the least remain attractive to the existing users.

Transportation is the activity of moving an individual or group and tools or goods from one place to another. There are 3 types of transportation: land, water and air. Transportation by type is grouped into private transportation and public transportation. In Kapuas Hulu there are 6 Bus Terminals, one of which is the Type B Bus Terminal in Kedamin which is the highest type bus terminal in Kapuas Hulu. For the Type B Bus Terminal, the Kedamin Terminal has not met the requirements stipulated in government regulations, so it is necessary to redesign it to meet the standard for the Type B terminal. Bus terminals that look dirty are due to the unloading and loading activities that are not in place so that it disturbs the comfort of bus terminal visitors. Supporting facilities for bus management activities is inadequate. Insufficient arrival and departure waiting areas. Activities on a regular basis are disrupting the circulation of vehicles, therefore it is necessary to redesign the Kedamin Bus Terminal. The Bus Terminal design applies a contextual concept to adapt the conditions of the building on site to the surrounding conditions.
