Abstract

The main objective of this study is to contemplate the awareness of entrepreneurs of sightseeing bus services as used by Thai travelers for private group tours and field trips through four considerations including 1) provision of convenient and safe buses; 2) provision of customer service satisfaction; 3) provision of experienced and well-behaved bus drivers; and 4) provision of bus services under travel safety. The study was carried out through interviews with 25 bus company representatives and found that factors which were raised the highest priority by entrepreneurs are provision of bus drivers having a valid driving license matching the vehicle type according to law and the provision of regular bus cleaning service. While a factor related to the provision of auto massage seats for relaxation was overlooked by all respondents. Moreover, the research team classified factors into 5 groups from A to E (highest to lowest awareness) using clustering analysis possibly making it easier to develop policy interventions appropriate with awareness of each entrepreneur group

Abstract

This paper studies train passing operation and determine line capacity by checking minimum headway. The analysis is based on the blocking time model displayed on the time space diagram where minimum headway and minimum waiting time are calculated. The study found that the capacity is affected by the number of blocks and the overtaking block position. The graph between the overtaking position and capacity is symmetrical, in which capacity is reducing when the overtaking position is far from the center of the line. The overtaking position that maximizes capacity is not affected by speed nor block length. In the case of even number of blocks, the appropriate location to overtake is (n / 2) +1 while in case of odd number of blocks, the overtake position is at (n+1)/2 and (n+3)/2. Both positions maximize the line capacity for each case. In addition, when the block length was reduced the capacity increased and decrease dwell time.

Abstract

At present, bicycle use for both health and tourism is supported but it is found that most Thai people do not popularly use bicycles. This study aimed to seek for the factors promoting Thai people to use bicycles by choosing KhaoYai National Park, where there are a large number of tourists, to be studied with the application of the Theory of planned behavior-TPB. The factors, which were considered, included Attitude, Subjective norm, Perceived behavioral control, and Additional factors which were the factor of infrastructure, and number of bicycle possession in the family. The data used in this study were 429 Thai tourists. The data analysis was done by using Structural Equation Modeling. From data analysis, it was found that Perceived behavioral control, Subjective norm, and Attitude influenced behavioral intention in bicycle use at statistical significance 0.01. For Infrastructure, and number of bicycle possession in the family, they positively influenced behavioral intention in bicycle use in KhaoYai National Park at statistical insignificance. This study can be used as guidelines for the government or involved organizations to determine the pertinent policies on promoting bicycle use.

Abstract

In Mauritius, travelling by bus service widely plays an important role in people’s transportation. In 2011, there were 220 bus routes for bus transportation, and 900 bus stops. This research aimed to study the satisfaction of bus users with a variety of service kinds divided into four main aspects including Vehicle, Driver behavior, Bus stop facility, and Service. The data used for analysis were obtained from 531 completely screened questionnaires inquiring bus users’ satisfaction in Mauritius. The data were analyzed using Decision tree to classify the importance of criteria for bus users’ satisfaction and the Importance performance analysis was used to identify Items in each quadrant of which the meaning was different. The result obtained for the most important question item will be used to improve bus service in order to serve bus users’ needs. From data analysis, it was found that the strength of bus service in Mauritius was Driver and crew’s customs, and the weaknesses were the frequency of bus service and the locations of bus stop facility. In terms of IPA analysis, the frequency of bus services should increase and the locations of bus stops should be safer.

Abstract

Bicycles offer non-motorized transport that not only reduces energy consumption and pollution but also offers health benefits. However, most Thai people do not use bicycles. This study investigates the willingness to pay (WTP) for bicycle hire at tourist attractions in Thailand, which can inform strategies that encourage more Thai people to use bicycles. Data analysis considered socio-economic factors, such as gender, age, and level of education, average household income per month, type of tourist attraction, frequency of bicycle use, and type of bicycle. The analyses included the independent sample t-test and analysis of variance F-test. The samples for the analysis comprise 704 Thai tourists. From the results, it was found that WTP for bicycle hire between respondents’ gender for the age groups lower than 18 years and between 30–44 years was different. For type of bicycle, the differences were at statistical significance 0.05. The group having WTP for bicycle hire at a confidence level of 95% shared the same level of education, Average household income per month, frequency of bicycle use, and type of tourist attraction were not different. Government sectors or involved organizations can use this study to inform guidelines around suitable bicycle hire for target groups.
