TITLE: Positioning Technology Using Mobile Phone
ABSTRACT: Location positioning technologies using mobile communication instruments are shown for monitoring individual travel behaviour. PHS (Personal Handy phone System) based on-line systems and off-line recording instrument are used for travel data collection. A new location positioning method will be presented which is available when the location of base stations may not be known. Data transfer algorithms are mentioned for estimating travel behaviour using a sequence of location positioning data in space-time dimensions. Some examples of travel data collection in actual urban areas are then presented.
SPEAKER: Professor Asakura is currently a professor at the Department of Architecture and Civil Engineering and the Graduate School of Science and Technology of Kobe University. He obtained his bachelor and doctoral degrees from Kyoto University in 1981 and 1988, respectively. He joined Ehime University as a lecturer in 1988, and was promoted to associate professor and then professor, before moving to Kobe University in 2002. Professor Asakura research interests are transport network analysis with a focus on network reliability and route choice modelling, and travel behavioural research with a focus on the behavioural monitoring using mobile communication instruments.

TITLE: Location Fixing Methods for 3G Mobile Phones
ABSTRACT: Mobile phone location fixing is an important issue for 3G emergency and location-based services, as well as Intelligent Transportation Systems applications. This talk will present some of the methods being proposed and developed, including a study of the cell ID-based, assisted GPS-based and TDOA-based approaches and their relative strengths and weaknesses.
SPEAKER: Dr. Nelson YUNG is an associate professor at the Department of Electrical and Electronic Engineering of the University of Hong Kong. He received his B.Sc. and Ph.D. degrees from the University of Newcastle-Upon-Tyne in 1982 and 1985 respectively. His research interests cover image processing, video analysis, surveillance and vehicle collision avoidance and navigation. Dr. Yung has co-authored a computer vision book, and has published over 100 journal and conference papers. He is a Chartered Electrical Engineer, Member of the HKIE, IEE and Senior member of the IEEE.
