This paper presents the design of an IoT based air pollution monitoring system to measure carbon dioxide gas, butane gas, humidity and temperature. The hardware consists of MQ-2 gas sensor, ESP8266 Wi-Fi module, DHT22 temperature and humidity sensors. Meanwhile, the software used in this prototype is the Arduino Integrated Development Environment (IDE) written in function C and C++. The monitoring system indicate air quality is below than 100 AQI for safety air quality and more than 200 AQI for hazardous air quality. The green LED illuminated indicates there is no hazardous gas detected. Meantime, when the butane gas or carbon dioxide gas is identified, the red LED is illuminated. All the data are sent through ThingSpeak and Blynk applications. In ThingSpeak and Blynk applications, the data are displayed and updated after detected by the sensors in every 15 seconds and 1 second. In the Blynk application, when the hazardous gas is detected, the Blynk application sends a notification to alert the users immediately.
Transit Oriented Development (TOD) is an emerging concept to optimise the land use development surrounding a transit station and to create a reliable relationship between a densely compact urban form and high public transportation ridership. In Malaysia, the concept of TOD was initiated in the first National Physical Plan in 2005 and mentioned again in National Physical Plan 2 in 2010. This paper identifies the principle of TOD applied in Malaysia and other countries, and discusses the differences and similarities of the TOD practices using comparative analysis and document analysis methods. Findings of this study indicate that mixed-use development, high density, intensity and connectivity are the main TOD principles adopted in Malaysia and other countries around the globe. The current policy and practises of these countries tend to focus more on the better management and increase ridership of these transit rail stations, including ways to encourage users to shift from private vehicles to public transportation. The findings of this study would contribute towards policy decisions and practices of TOD in Malaysia.
In the past years, the concept of Transit-Oriented Development has been adopted in cities and countries including Malaysia and Singapore. The integration of land use and public transport stations through Transit Oriented Development (TOD) as part of urban and cities strategy is highly acclaimed in promoting sustainable development concept in cities development. To understand the performance of TODs implementation in Klang Valley, this study has selected eleven stations in of Mass Rapid Transit (MRT) Putrajaya Line as case studies. This paper aims to evaluate the current implementation of TODs in Malaysia, benchmarked against the TOD land use composition and percentage from Singapore’s model. The findings show that Raja Uda, Ampang Park and Persiaran KLCC stations show significant performance. However, Bandar Malaysia North station displayed poor result with the lowest percentage of residential and commercial components. All stations did not achieve the ideal TOD value for residential land use and eight out of eleven stations recorded higher than the ideal TOD value for roads. However, highest number of stations achieved the ideal TOD value for mixed-use and commercial land uses. These results would help policymakers to improve the current implementation of TODs in Malaysia.
Despite the fading cultural value as a Chinatown, the relationship of the society and its public space is a form of a natural phenomenon that is inseparable. The changing functions of public space in Malaysia were identified to decrease the quality of social and cultural activities in Petaling Street. Therefore, this study aims to explore urban public spaces as the main social driver in crating interaction in Petaling Street, Kuala Lumpur. The relationship between attributes of the urban public space and visitor retention were analyzed in this study. In terms of social interaction, the user activities were interrelated with the sociability of the urban space. The questionnaire survey was selected as the main medium for data collection distributed to the visitors and locals within the Klang Valley who have visited Petaling Street Chinatown. A total of 150 respondents involved and the analysis shows that street furniture does affect their preferences in an urban public space. Furthermore, the time spent by respondents will increase depending on the external factors such as weather and aesthetics. On the other hand, the internal factor that contributes to the number of visitors in Petaling Street Chinatown is their accompanying traveler which in the context of a solo traveler, the street should be celebrated with vibrancy.
National Transport Policy (2019-2030) strives to improve the transportation sector towards a conducive and competitive sector while fulfils the demands of people. The new development of Mass Rapid Transit (MRT2) Sungai Buloh – Subang – Putrajaya Line is expected to complete in 2022 and would benefit 529,000 users. This paper analyses the preferences of users on the facility provision at mass rapid transit stations in the local context. This paper was based on secondary and primary data sources such as official documents, websites and data collected for the Integrated MRT2 Land Use Masterplan. Document analysis method was employed to review official sources from public transport providers across selected benchmarked countries. Six categories of facility at mass rapid transit stations were evaluated using 40 criteria. Results suggested improvements are needed in barrier-free considerations and convenient facilities. Statistical analyses, involving descriptive and inferential analyses, were conducted. The results show that gender and travel time to station influenced users’ preferences on facilities needed at stations. This paper suggests that certain criteria of facilities must be considered based on universal needs of the population to encourage usage of MRT2 as public transport as well as to provide convenient travel experiences.
