Passenger Rail Service Comfortability in Kuala Lumpur Urban Transit System
Rail transit transportation system is among the public transportation network in 
Kuala Lumpur City. Some important elements in establishing this system are ticket price, 
operation cost, maintenance implications, service quality and passenger’s comfortability. The 
level of passenger’s comfortability in the coach is important to be considered by the relevant 
authorities and system operators in order to provide comfort and safety to passengers. The 
objective this research is to study some parameters that impact the comfortability of passengers 
and to obtain feedbacks from passengers for different rail transit system. Site observations were 
conducted to obtain data such as noise, vibration, speed and coach layouts which will be 
verified by using the passenger feedback outcomes. The research will be focused in and around 
the Kuala Lumpur City for the duration of 10 months. Four rail transit systems were being 
considered, i.e. Train Type A (LRA), Train Type B (LRB), Train Type C (MRL) and Train 
Type D (CTR). Data parameters obtained from field observations were conducted in the rail 
coaches during actual operation using apparatus among others the sound level meter (SLM), 
vibration analyzer (VA) and the global positioning system (GPS). Questionnaires were 
prepared as passenger feedback instrument, focusing on the level of comfortability in rail 
coaches. The outcomes of these analyses showed that CTR was the best and most comfortable 
coach, followed by LRA, LRB and MRL. Using the passenger feedbacks (MBP) it was also 
found that the ranking values for the railway transit system using Rail Coach Comfortability 
(RCC) is RCC (MBP) were the same as the outcomes using the RCC (parameters). In 
conclusion, it was found that this research has successfully determined the level of 
comfortability as determined in its aim and objectives. From this research, it is hoped that the 
relevant authorities will continue to find ways to enhance the comfortability and safety of its 
train coaches especially its passengers and the community at large.
Appraisal on Different Sustainable Road Stabilization Techniques for Different Road Condition and Materials
Road condition in term of road surface condition depends on the subgrade soil strength. Therefore, a weak subgrade condition requires improvements in stabilization. Soil stabilization is the alteration of one or more geotechnical properties to create an improved soil material possessing the desired engineering properties. The main purpose of the soil stabilization is to increase the shear strength of an existing ground condition to enhance its load-bearing capacity, achieve a desired improved permeability and enhance the durability of the soil to resistance to the process of weathering, and traffic usage among others. Three method in soil stabilization considered in this study are chemical admixture, mechanical and geosynthetics methods. The difference in soil stabilization methods depends on the different road surface conditions. Road condition with weakness subgrade is more appropriate and economical in used stabilization chemical method. In this paper, discussing the road condition requires the ground improvement through soil stabilization
Do Potential People Have Moral Rights?
By a potential person I shall mean an entity which is not now a person but which is capable of developing into a person, given certain biologically and/or technologically possible conditions. This is admittedly a narrower sense than some would attach to the term ‘potential'. After all, people of the twenty-fifth century, if such there will be, are in some sense potential people now, even though the specific biological entities from which they will develop, i.e. the particular gametes or concepti, do not yet exist. For there do exist, in the reproductive capacities of people now living and in the earth's resources, conditions adequate to produce these future people eventually, provided of course that various possible catastrophes are avoided. Indeed, in some sense of ‘potential’ there have been countless billions of potential people from the beginning of time. But I am concerned not with such remote potentialities but with currently existing entities that are capable of developing into people.
