Bibliometric Analysis on Street Network components in Influencing Genome of Urban Morphologies
Get PDFThe bibliometric is a type of research method used in library and information science. The objective of the study are to overview the influences of street network elements comprises of street hierarchy , permeability and urban streetscapes in studying genome of urban morphologies. The quantitative analysis and statistic was used to describe a pattern of publication in the given body of literature. The publications from Scopus and Web of Science were compiled and anlyzed further. The finding shows that, the genome of urban morphologies have being influenced by the street network components nalemy street hierarchy, permeability and legibility, streescapes and pedestrian movement. These components were mutually present in the urban morphology genome which have the capability in accelerating the movement of city. Street hierarchy shows that hierarchical street becomes an organism that vital for the city’s development. The transition of hierarchical system of street contribute to the changes or evolution of the city from time to time. Meanwhile, permeability is represent the image of city. The physical and visual of image of a city is important to bring the city into global level. However, inconsistency of implementation of permeability element will provides a negative impact on the place. Urban streetscape is essential to avoid negative impression of the city images where it should provide visual richness to the city. Lastly, the pedestrian accessibility attract the movement of publis space with the integration of street network. In conclusion, the street network components mutually influenced the morphology of the city over time and become a backbone for the city to reflects the urbanization process. However, based on the bibliometric analysis, the study of street netwok morphology is not grasp sufficent attention from the Asian country
Cost Performance for Residential Building Projects
Get PDFThe construction industry is one of the main sectors that play basic role in the urban and rural development of a society. It provides important ingredients for the development of an economy. However, many construction projects experience extensive cost overrun. This study is conducted to: (1) reveal the magnitude and direction of cost overrun in building construction projects implemented in the West Bank - Palestine over the years 2013 to 2018, (2) develop prediction models for predicting project cost overrun based on the contract price value, (3) identify the causes of cost overrun in building construction contracts in the West Bank – Palestine, (4) test the importance of cost overrun causes from consultants and contractors’ perspective. To achieve the study objectives, two methods are followed: (1) Field data collection for 102 building construction projects implemented in the West Bank during the period 2013 and 2018, (2) A questionnaire survey was conducted to identify and rank cost overrun causes from the perspectives of contractors and consultants. The findings reveal that100% of projects suffer from cost overrun with average of 34.58%, ranging from 15% to about 88%. The results show that cost overruns for building projects increased with contract prices. The questionnaire survey reveals that the top five cost overrun causes from combined view are: experience in contracts, insufficient time for estimate, incomplete drawings, materials’ price fluctuation, and political situation. It is hoped that the findings will guide efforts to improve the performance of construction industry in Palestine and other developing countries
TRANSIT-ORIENTED DEVELOPMENT (TOD) PLANNING ANALYSIS BY INTEGRATING GEOGRAPHIC INFORMATION SYSTEM (GIS) APPROACH
Get PDFThe development of TODs in Malaysia is still unclear because of no specific development and planning guidelines relating to TOD have been gazetted at the federal level. The objectives for this study are; (1) identifying land-use dimension to determine the potential of TOD development, (2) to analyse the potential of rail-based stations for TOD purposes based on five land-use dimension analysis, (3) to rank TOD typology of rail-based stations using GISMCDM technique and (4) to recommend the use of geospatial approach as a transportation planning solutions. The area of analysis will be within 400 meters radius from the rail-based stations in Shah Alam City Council. The analysis of research was evaluated on the land-use criteria comprising of coverage area, land availability, gentrification potential, density and diversity. The finding shows that the KTM Padang Jawa was identified as the most potential stations with scores of 80%. The least potential station is Skypark Link Subang Airport with scores of 40%. Result shows that the typology for two stations are determined as’ second-highest TOD intensity’ and ‘third-highest TOD intensity’. This study will provide a better understanding of how the land-use dimensions of TOD potential analysis are integrated into GIS application which is significant in many ways
PUBLIC PARTICIPATION ASSESSMENT FOR ENVIRONMENTAL IMPACT ASSESSMENT IN MALAYSIA, CANADA AND NEW ZEALAND
Get PDFIn 1975, the Environmental Impact Assessment (EIA) was promulgated in Malaysia after the enactment of Environmental Quality Act (EQA) in 1974. Although the EIA is integrated for nearly five decades, the effective public participation application for EIA remained scant in the Malaysian environment. This paper provides a comparative study on public participation application for EIA in Malaysia, Canada and New Zealand. This study is administered by analysing the current EIA process and EIA legislation pertaining to the public participation for EIA in the three countries via literature review. This paper examines the similarities and differences between the three countries on their application of public participation for EIA. It is paramount to examine the current application of public participation administered for EIA in the Malaysian environment with other developed countries to induce effective public participation for EIA in Malaysia
SPATIAL MAPPING OF ENVIRONMENTAL SENSITIVE INDEX IN PULAU HUJUNG AND PULAU TENGAH, JOHOR
Get PDFThis paper addresses the necessity of sea spatial mapping for valuable natural resources of the island ecosystem in Pulau Hujung and Pulau Tengah, Johor. These islands are located in Johor Marine Park, rich with a diversity of marine life, resources, valuable ecosystems, and historical and cultural values. As an environmental asset considered as Environmental Sensitive Areas (ESA), the spatial mapping of its different zonal uses by using the Environmental Sensitive Index (ESI) is crucial in planning and managing natural resources within protected areas. By integrating the data of ESAs into the GIS application via the ESI, the generation of its outcome of digital mapping is easier to understand and applicable in managing the planning of the islands. The indices of ESI comprise of biological and human resources, and shoreline classification. Besides, the research refers to international guidance, namely the IUCN Guideline 2008 where the requirements of ESA protection were clearly stated. The results of the spatial mapping demonstrate that the islands could be categorised as preservation zone, habitat protection zone, general use zone, and buffer zone, in which each of these sea zonal use reflects both its characteristics and importance. The division of clear zones helps the relevant authorities to manage and monitor this special area so that these natural resources, marine life, and ecosystems can be sustained as the natural heritage of the nation. In a conclusion, it is evident that the spatial sea zonal use map is very significant and may benefit many stakeholders involved in planning and managing the waters of the eastern part of Johor.
 
USERS’ PERCEPTIONS ON PARKING UTILIZATION PATTERN AT PARK-AND-RIDE FACILITY IN PUTRAJAYA SENTRAL
Get PDFThe increasing number of private vehicles in Federal Territory of Kuala Lumpur and Putrajaya has created inadequate parking spaces and traffic congestion. The limited parking spaces for the public at Government complexes and its surroundings in Putrajaya had lead to the increasing number of illegal parking. As an initiative to encounter this problem, the concerned authority had provided the park-and-ride facilities at public transportation terminal in Putrajaya. The provision of park-and-ride scheme would obviously promote the use of rail transit, thus shifting the users from using motorcar to public transport. Putrajaya Sentral is the main public transportation hub of Putrajaya which provides multi-modal public transportation services such as Express Rail Link (ERL), intercity buses, intra-city buses namely as ‘Nadi Putra’, express buses and taxi services. However, the existing parking spaces at the park and ride facility in Putrajaya Sentral are not fully utilized. Thus, this paper highlights the user’s perceptions on parking utilization pattern at Putrajaya Sentral park and ride facility in order to examine the current parking demand at the parking facility. Parking inventory survey to determine existing physical conditions of the parking facility and questionnaire survey to evaluate the perceptions of the users on the parking usage pattern were administered. The findings showed that most of the users (78%) parked their vehicles for longer duration (more than eight hours). The multi-storey parking facility was found to have higher demand than surface parking due to minimal parking fees and longer operation hours. The major factors that influenced the users in using the park-and-ride facility are “avoiding traffic congestionâ€, “convenience of travel with public transportâ€, “less stress by travelling with public transport†and “parking at destination are too expensiveâ€. Few recommendations to overcome the identified problems and conclusions are also drawn
COLLECTION AND PHYSICAL CHARACTERIZATION OF AIRBORNE PARTICULATES
Get PDFAirborne particulates are one of the most complex air pollutants and considerable concern surrounds their environmental impact especially with regards to human health. An investigation on the efficiency of various total inhalable and respirable dust samplers has been conducted to identify the most convenient way of collecting dust particles to examine their physical characteristics. The efficiency of a variety of dust samplers were investigated using limestone dust clouds generated inside an environmental dust chamber. Various sampling periods were employed to establish dust concentrations in the environmental dust chamber. The experimental dust cloud was found to contain on average 55.74 % of respirable dust as defined by different instruments while a consistent dust concentration of approx 200 mg/m3 was repeatedly produced.
The methods for collecting and estimating airborne asbestos fibre concentrations were studied and found to be extremely limited. Standard optical techniques grossly underestimated both airborne fibre concentrations and respirable dimensions of fibres. The size and dimensions of respirable asbestos fibres are defined by their ability to gain access to the lungs and there is no instrument or technique available at present, which will allow collection and estimation of respirable fibrous dust clouds. A comparison of coal dust particles with similar particles retained in the lungs has shown a difference from the predicted respirable fractions as proposed by the British Medical Research Council (BMRC) and other conventions. Respirable dust sampling instruments may therefore be more suited forsampling larger particles. The difficulty in estimating the characteristics of airborne particulate material has been demonstrated by illustrating urban particulate collection and analysis. The extremely large differences in terms of physical size, and aerodynamic properties of dust particles formed by different materials have been demonstrated.

Biophilia: Residents’ Connection with Green Infrastructure in a Town
Get PDFGreen infrastructure is urban nature consisting of greenery and green spaces distributed in and around town. It facilitates residents’ contact with natural environment that may fulfil their needs for nature in urban places.Human’s inherent affiliation with the natural environment or Biophilia has been long hypotesised. The paper draws the findings of a case study exploration on the connection between residents with green infrastructure in Taiping, a small colonial town in Peninsular Malaysia. Biophilic tendency of residents to green infrastructure in the town was elicited using questionnaire survey (n=335) and semi-structured interviews (n=33). The results show that residents who participated in activities within the greenery and open spaces in the town experienced various benefits that fulfil their needs for nature. Physically, participating in activities provided the residents active living. Physical and visual experience afforded relaxation, comfort and calmness. More social interactions were experienced resulting in community satisfaction. The study concludes that existence of matured green infrastructure extends beyond aesthetic enjoyment. It provides urban residents with a connection to nature that induces affiliation with green infrastructure in a town. Thus, planning and provision of green infrastructure with care by urban planners and designers are essential in the urban fabrics
