HPC Symposium 2016: Accelerating the Way to a Smart Nation
Details to be announced
Dr. Muhamad Azfar Ramli, IHPC and Mr. Loh Zhi Ping, SMRT Buses Ltd
In this talk, we share various challenges faced by local public bus operators in achieving high standards of reliability to meet the needs of the commuter. The intricate relationships between bus captains, operations controllers, bus logistics, schedule design and the dynamics of commuting patterns are highly complex and their individual impact on the reliability of bus operations is therefore difficult to discern.
We share how the use of automated data collection on bus location and passenger fare collection has contributed enormously to a better understanding of the dynamics of bus operations. We thereby demonstrate that through a data-driven simulation and modelling approach, the operations can be more easily understood to anticipate the dynamic changes to the operating landscape in Singapore.

Under the 3rd Green Building Master Plan (GBMP), Green Mark aims to further encourage the adoption of natural ventilation and passive design in buildings designs to minimize energy consumption. As a result from this GBMP, BCA has funded a research project team made up of IHPC (PI role), NUS, Eindhoven University and BSD Pte Ltd to develop an enhanced set of CFD simulation and evaluation method for ascertaining the air quality of indoor environments, the level of comfort of occupants (thermal comfort and IAQ index) and the ability to mitigate extensive rain penetration (WDR modelling) in naturally ventilated spaces. Specific criteria will be developed for natural ventilation design in six (6) non-residential building types, namely healthcare facilities, industrial facilities, hawker centres, sports facilities, commercial atriums and schools. Findings from this research project will be considered in the development of new criteria in new Green Mark schemes.

The National Science Experiment (NSE), themed “Step Out for Science”, is an island-wide outdoor science experiment carried out by Singapore students to track their carbon footprint, travel mobility patterns, and the amount of time they spend indoors and outdoors. In 2015, 43,140 students from 128 schools carried the SENSg device to collect data on their daily travel patterns and to map Singapore’s urban outdoor environment such as temperature, humidity and sound, or Wi-Fi connectivity. A key goal of the NSE is to interest students in science, technology, engineering and mathematics (STEM), and students’ curiosity in science was sparked as they learned concepts such as Big Data, along with the Internet of Things as part of the project. I will describe our work in developing a highly available, distributed computing infrastructure over our data centres at both Fusionopolis and Biopolis, and the key findings of the NSE 2015.
In this talk, I will also describe the Dynamic Mobility Management (DMM) project, under the A*STAR-Fujitsu-SMU Centre of Excellence on Urban Computing and Engineering. The Centre’s objective is to harness high performance computing capabilities to develop solutions for sustainable urban operations such as crowd mobility and transport engineering, with researchers using Singapore as a “living lab” to test-bed next generation solutions to real urban issues. I will describe the specific objectives of DMM and our early progresses in developing methods to understand and improve the dynamics of commuter traffic in large urban spaces, as well as manage crowds under extreme conditions and surges
Dr. Ronnie Lee, IDA Singapore
Virtual Singapore is conceived as an intelligent, computable digital twin of the physical Singapore to cater for geospatial intelligence, virtual experimentation, research, planning and provision of pre-emptive services. Virtual Singapore also catalyses research in Virtual City Models (VCM) from its production, maintenance and usage.
Dr. Yang Yinping, IHPC
I will also share several avenues the solutions and research capabilities can be extended for new applications and prospective collaboration.
Mr. Mohit Sindhwani, Quantum Inventions Pte Ltd and Dr. Liu Enxiao, IHPC
Commuters in mega-cities need to access static and real-time information to make right decisions about their navigation including multi-modal or inter-modal navigation and travel. At the same time, sensors deployed in smart cities can provide commuters with enhanced information for them to have different travel options and to select an optimal navigation plan.
Dr. Miao Haiyan, IHPC
In this work, we have developed a coupled mesoscale and microscale climate model for risk assessment of urban wind channels in Singapore. A high resolution mesoscale spectral model (MSM) has been adapted and calibrated for Singapore, to downscale hourly weather fields at 1km spatial resolution. The downscaled weather fields are then fed into a Computational Fluid Dynamics (CFD) urban model as the initial and boundary conditions to simulate 3D wind and pressure with high resolution at 1-2 meters. With the hourly weather fields at 1 km spatial resolution, the coupled MSM-CFD model is then used to study the effect of wind channels on urban biodiversity, particularly on tree failure, in the urbanized Garden City, Singapore. The MSM-CFD model indicated a correlation between the predicted strong wind gust area and tree failure recorded over Marina Bay. We conducted a risk assessment study of urban wind channels over the urbanized Marina Bay caused by a tropical cyclone, Vamei, which traversed close to Singapore on the 27 Dec 2001. The impact of climate change on wind channel distribution was also studied.

Noise is one of the important factors determining the liveability in urban areas. As we further intensify the land use, it is inevitable that buildings will be exposed to higher ambient noise level generated by various noise sources. To address the issue of high noise levels while maintaining natural ventilation is a challenge. In a high-rise high density living, the building envelop often constitutes to the primary path for external noise sources to travel into the living environment. The project is committed to investigating and developing advanced technological solutions to improve aural and thermal comfort in the living environment. In particular, new window designs that can substantially reduce noise transmission and at the same time maintain ventilation function to achieve good thermal comfort and resource efficiency will be studied. Here we present a few different window designs with dual functions, the numerical models and simulation results to evaluate the transmission loss, and the optimization window design results. This gives the basis for further developing windows, with addition of smart materials and active control elements.
Dr. Koh Wee Shing, IHPC and Mr. Tan Sze Tiong, HDB
Cities today generates enormous amount of data. Through research and advancement in ICT, we see many examples on how cities capitalise on data analytics to gain better insights on its performance and improve to the quality of life for its residents. With the vision for Singapore to be a Smart Nation, HDB has embarked on an exciting journey to develop Smart HDB Town. As part of the Urban Habitat Domain, HDB has developed a Smart HDB Town framework to help drive greater ‘smartness’ to enhance sustainability, resilience and liveability in HDB towns and estates. The framework maps out key strategies on how HDB introduces “Smart” solutions, focusing on four key dimensions of Smart Planning, Smart Environment, Smart Estate and Smart Living. Technology like advanced 3D visualisation and urban analytic will be an essential enabler to achieve this vision. Through engagement with residents, HDB will pilot selected technologies in selected living laboratories, to bring the real smart solutions to daily life and their neighbourhood. The success of these initiatives will drive evidence-based approach to planning and design for our future towns.
