Abstract.Thailand is now entering to an aging society, as the number of elderly will increase to 25.2 million people in the year 2030 [1]. From the statistics of National Statistical office 2007, the number of people with disabilities (PwDs) is approximately 2.9% or 1.7 million people of the total population. The Thai government has recently enacted many policies and acts specifically to equal the right of these people to be able to live like a normal person. One of the aspects of these acts is enabling them to access transportation services without difficulties. As Thailand has recently invested large amount budget on developing many railway projects, thus this is an important opportunity to enhance the design standard of transportation facilities to meet the demands of all types of users. This research is aimed to compare the laws and guidelines of railway station and facilities designed for all at international level and to explore the principles of railway station design that used for railway station design in order to make the recommendation for Thai railway station design to improve accessibility in terms of designs and additional facilities.
This study focuses on the future changes to the urban form around the Salaya railway station, which will be developed as a terminal station of the Bangkok metro service. The purpose is to investigate stakeholder attitudes to the transit-oriented development (TOD) approach to the station premises. The attitudes of local businesses and key stakeholders to joint programs on infrastructure development and the surrounding area are identified as local businesses encouraging the collaborative urban regeneration program. The approach uses scenarios as a tool for participatory planning to help identify future applications, including a workshop in two parts. The first part was conducted using group interviews with local entrepreneurs to raise the idea of the collaborative urban regeneration program. The second part was an evaluation of the program by the three key stakeholder groups: municipality, railway operators, and real estate investors. The scenarios evaluated by the key stakeholders indicate the different attitudes to the collaborative urban regeneration program depending on the role of each stakeholder. The collaborative program developed by local entrepreneurs can be classified by economic and physical factors. The findings suggest a common aspect for future collaboration in marketing strategies, such as advertising representing localness, as both local entrepreneurs and key stakeholders mostly agreed on the program. Disagreement on collaborative urban regeneration depends more on the specific role of the company or organization.
Nowadays, construction cost plays an essential role in various projects, which are buildings, roads, railways, and bridges projects. Conceptual cost estimation in feasibility study is require high accuracy and less validation error especially in construction projects at early stages. The more improvement of estimation techniques, it would lead to the lesser problems of cost overrun, and extra expenses. This paper developed a cost estimation model for new constructed rural road projects. Considering the estimation methods for predicting the cost model, parametric method based on regression learner and NN method are applied. Previously, many researchers studied the cost applicable model by using various computer applications, so that this paper differed to compare these methods based on MATLAB. Accordingly, 44 road projects were compiled from DRR database, after that identifying the effective cost parameters referred on collected data. Subsequently, the data implementation process was focusing with regression learner based on automated regression training, and lastly, with NN toolbox concentrated on nftool for simulating the cost models. Another 7 road projects are tested with holdout validation process for these models. Due to this validation, we compare the predicted cost models within these methods. Finally, the developed models are reliable for not only the conceptual phase of future rural road projects but also the related construction fields can be recovered about the cost model creation.
