1. Smart Address Plates for Pedestrian Indoor Navigation and Location-Based Services and Management (Silver Medal)

Traditionally, pedestrian navigation uses Location Positioning System (LPS) with trilateration to find the user’s position, which have very high positioning error for outdoor GPS and indoor positioning. This new solution adopts a cost-effective innovative Location Confirmation System (LCS) to accurately locate and guide the user to the destination by using Smart Address Plates (SAP) that transmit stored geographic coordinates with innovative 3D Smart Address (SA) codes to the users even without WiFi or telephone signals. This SAP system can help to find shops/ offices/ restaurants/ car parking spaces inside a multi-storey building accurately while providing location-based services and management for precise target marketing. It is highly scalable, connecting shops/rooms on a floor to a building, then to a district and to the whole city through a Smart Address Plate Management System (SAP-MS).

The Smart Address Plates and Location Confirmation System were developed by Professor Anthony Yeh, Dr Zhong Teng and Dr Run Shi from the Department of Urban Planning and Design, The University of Hong Kong.

2. Remote e-Inspection System for the Manufacturing and Delivery of Offsite Modular Construction (Bronze Medal)

This e-Inspection System is a Modular Construction Supply Chain Quality Assurance system that includes i-Core (an loT device attached to each MC module to monitor the position, humidity, temperature and collision data), e-InStar (an App for uploading the checking result of each production step in a remote factory to the block chain), e-TranStar (an App for monitoring the location and condition of the MC module in the transport process) and a blockchain-based backend. Designed for offsite modular construction use to help solve housing problems, it reduces resources required for supervision and paperwork while ensuring tamper-proof data, helping overcome the current difficulties in monitoring the quality of production and transportation from remote sites. The system has been piloted in an HKU project in Hong Kong with two 17-storey buildings using 952 MiC modules. This project has also received the Hong Kong ICT Smart Mobility (Smart Logistics) Gold Award in November 2022 and the 12th Guangdong-Hong Kong IoT Competition Best IoT Innovation Award in December 2022.

The system was developed by Prof Wilson Lu, Director of the iLab of the Faculty of Architecture, together with Professor Anthony Yeh, Chair Professor of the Department of Urban Planning and Design, and Mr KL Tam, Former Director of the Estates Office of the University of Hong Kong.

Digitalization in the Service of Society: Harnessing Big Vehicle Trajectory Data


DOWNLOAD LECTURE POSTER

SPEAKER:

Prof. Christian S. Jensen

Professor of Computer Science at Aalborg University, Denmark


DATE & TIME:

May 3 (Wednesday) 17:00-18:00 HKT


VENUE:

CPD-2.42, Centennial Campus, HKU


ABSTRACT:

The ongoing, sweeping digitalization of societal processes yields massive volumes of data that capture the underlying processes at an unprecedented level of detail, in turn enabling us to better understand and improve those processes. Put differently, if harnessed properly, data holds the potential to enable value creation throughout society.

Considering primarily vehicle trajectory data, this talk puts focus on the important process of transportation: While we all depend on it for mobility, transportation has adverse effects on our productivity due to lack of predictability and congestion, on the climate due to greenhouse gas emissions, and our health and safety due to air and noise pollution and accidents. In sum, it makes sense to invent techniques capable of leveraging trajectory data for the improvement of transportation.


This talk will describe how the availability of massive trajectory data renders the traditional routing paradigm, where a road network is modelled as an edge-weighted graph, inadequate. Instead, new paradigms that thrive on massive trajectory data are called for. The talk will cover several such paradigms. As even massive volumes of trajectory data are sparse in these settings, the talk will also cover means of making good use of available data.

Cyclists as Intelligent Carriers of Space-time Environmental Information: Crowd-sourced Sensor Data for Local Air Quality Measurement and Mobility Analysis in the Netherlands

DOWNLOAD LECTURE POSTER

SPEAKERS:

Prof. Peter Nijkamp Emeritus Professor in regional and urban economics and in economic geography, VU University, The Netherlands

Dr. Karima Kourtit Assistant-professor at the Open University, Heerlen, The Netherlands


DATE & TIME:

April 21 (Friday) 11:00-12:00 HKT


VENUE:

Social Sciences Chamber, 11/F, The Jockey Club Tower, Centennial Campus, HKU


ABSTRACT:

In recent years, slow travel modes (walking, cycling) have gained much interest in the context of urban air quality management. This article presents the findings from a novel air quality measurement experiment in the Netherlands, by regarding cyclists as carriers and transmitters of real-world information on fine-grained air quality conditions. Using individual sensors on bicycles—connected to a GPS positioning system—online local pollution information originating from cyclists’ detailed spatial mobility patterns is obtained. Such air quality surface maps and cyclists’ mobility maps are then used to identify whether there are significant differences between the actual route choice and the cyclists’ shortest route choice, so as to identify the implications of poor air quality conditions for their mobility choices. Thus, the article seeks to present both a detailed pollution surface map and the complex space-time mobility patterns of cyclists in a region, on the basis of online quantitative data—at any point in time and space—from bicycle users in a given locality. In addition, the article estimates their response—in terms of route choice—to detailed air-quality information through the use of a novel geoscience-inspired analysis of space-time “big data.” The empirical test of our quantitative modeling approach was carried out for the Greater Utrecht area in the Netherlands. Our findings confirm that spatial concentration of air pollutants have great consequences for bike users’ route choice patterns, especially in the case of non-commuting trips. We also find that cyclists make longer trips on weekends and in the evenings, especially towards parks and natural amenities.
