Design principle for public transportation infographic

Infographics is a visual representation of data. Today, people learn faster and remember things more efficiently and effectively through the use of text and visuals than using the conventional textual method alone. Infographics can be used in visualization to enhance data interpretation and knowledge discovery. Many businesses use infographic elements that are hard to digest and understand. Visualization can be insufficient or ineffective, thus messages can be transferred well or they can be wrongly transferred. Businesses with lack of graphical representation skills usually meet with this kind of challenge. Preliminary study has found that transportation companies may not follow any design principle to design infographics. This can cause data to be poorly defined with uninteresting graphics which eventually do not trigger target audiences’ interest or unable to engage them. Besides, this process can affect the businesses’ revenues and customers’ satisfaction. A qualitative method was applied in this study. A design principle for public transportation infographic was developed based on three main principles which were Gestalt theory, components of infographics and components of public transportation. Gestalt theory introduces the theory of similarity, figure-ground, proximity, common region, focal point, closure, and continuity. Components of infographic include visual element, content element, and knowledge. Components of public transportation are unit of carriage, transportation terminals, travel directions and durations, safety, accessibility, reliability, and fares. A qualitative methodology was applied to evaluate the proposed principles. Five experts in infographics and visualization were assigned to evaluate the reliability of both the questionnaire and the infographic design principles. Findings from the expert’s review show the content validity index 0.95 for questionnaire and 0.89 for the design principle Infographic. Therefore, the result is acceptable. It is hoped that the developed design principle in public transportation will give good impacts in developing and enhancing infographics

Proposed data quality evaluation method for a transportation agency

The data quality evaluation is essential towards designing a data assessment method for any company because data is an important asset. Therefore, the purpose of this study is to develop the data quality evaluation method for a transportation agency in Malaysia in order to quantify the quality of data in the SIKAP licensing system. This can benefit the transportation agency to improve the quality of data for the use of reporting, forecasting business operations and data integration with other agency’s systems. The relevant data evaluation dimensions have been identified from literature study and relative data evaluation framework which are necessarily required by the transportation agency to maintain high data quality in the SIKAP system. The process design for the proposed method involves data dimension identification, capturing the relevant database structure, subjective evaluation with a questionnaire and objective evaluation with data profiling. From the design process, the result shows that data evaluation method for a transportation agency must have a minimum of six data quality dimensions. SIKAP, the legacy system is in the process to revamp into a new system. Thus, this research contributes to enhance the current system’s data quality during revamping process and data migration into the new system

Preliminary review of model-view-presenter (MVP) and usability design for the development of postgraduate web portal

The process of managing and monitoring postgraduate students should enable mobility to the individuals involved, should not use high human effort and should provide transparent monitoring. Therefore, it needs a solution that could enable mobility, reduce human effort and provide transparent monitoring. A possible of it is through web portal that allows reducing numbers of physical meetings, avoiding double key-in, and allowing authorized personnel to easily access, monitor and analyzing data. Developing a good web portal requires good web pattern design which should be done prior or in earlier stage of a software development as a blueprint of the development. The web design of a web portal development as one of the web dimensions refers to the visualization of the web. Web pattern design has been used to solve commonly occurring problems in web portal development. This paper focuses on the preliminary review of modelview- presenter (MVP) web pattern design and usability heuristics for the development of postgraduate portal. It will discuss some of the existing web pattern design and the selections of the web pattern design which suitable to the development of postgraduate web portal
