Number of Participants: 31Purpose
As a follow up to the previous workshops on TransportLogistics, “The Fifth Workshop on Transport Logistics” washeld in Center for Maritime Studies, National University ofSingapore, Singapore on 14th December 2011. Theworkshop covered several topics in urban transportation andlogistics with a main focus on issues relating to humansafety and security. The main objective is to share theongoing research works carried out by academics andresearchers from the two GCOE collaborative researchgroups in National University of Singapore and in Kyoto
University.
Achievement and Results
The workshop begun with a warm welcome addressfrom Prof. Bernard Tan, followed by opening addresses fromProf. Tien Fang Fwa and Prof. Eiichi Taniguchi. Professors
and researchers from National University of Singapore andKyoto University discussed several topics in transportationand logistics where concept of human security was directlyaddressed. Humanitarian Logistics, Hazardous MaterialLogistics, Transportation Networks, Accident Analysis, Urban
Road Pricing are among the topics discussed.
A total of 9 presentations were made each followed bya vibrant question and answer session. The workshop
served as a platform to discuss several issues of urban
transportation and logistics and emphasized several new
research problems in the field. Considering effectiveness ofthe workshop to exchange new research ideas andprogresses between the two collaborative groups, the event
concluded emphasizing the need of future organization ofsuch events.

Introduction
The Fifth Workshop on Transport Logistics was held
successfully with active participation of academics andresearchers from the two host institutions, the National
University of Singapore, Singapore and the Kyoto University,
Japan. A total of 31 delegates attended the workshop. Theworkshop covered several topics of transportation and logistics
in the form of presentations and discussions. The focus wasissues relating to human security. Four main sessions were held,composing of a total of nine presentations. Each thirty minutepresentation was followed by a vibrant question-and-answersession.
Presentations
Presentation 1: “Humanitarian Logistics in the Great Tohoku
Disasters 2011” by Prof. Eiichi Taniguchi (Kyoto University)
Demonstrating the actual difficulties that arose during relief
distribution after “The Great East Japan Earthquake andTsunami Disaster” in Tohoku region Japan, the presentationshows how the humanitarian logistics differ from commercial
logistics system. It addresses some key logistics issues in caseof disaster based on the interviews performed at the affectedarea and highlights some essential points that can result therelief distribution more smooth.
Presentation 2: “MICROCITY-based Transport NetworkAnalysis" by Dr. Sun Zhuo (National University of Singapore)
Considering the drawbacks of previous software package
most of which are closed source and therefore cannot be
evaluated under uniform standard, the presentation introduce a
Microcity-based urban spatial analysis and simulation
framework. The framework allows layering of three softwares,
which provides flexibilities in developing various types oftransportation analysis models. Moreover, it benefits
practitioners and planners with integrated efficiency solutions
while keeping the modeling efforts to low.
Presentation 3: “Evaluation of Urban Freight Road Pricing with
Multi-Agent Modelling Approach” by Mr. Joel Sze TEO (KyotoUniversity)
This presentation proposed a multi-agent model toevaluate Government-driven City Logistics scheme like urban
freight road pricing on rising trend of home delivery. The
proposed model incorporates decision making behavior formajor stakeholders. Test results of interaction between carriers
administrator and shippers were presented on a virtual networkwith 16 customers 4 carriers 5 shippers and 1 administrator.
Presentation 4: “Nonlinear Congestion Pricing – Model
Development and Distributed Algorithm Design" by Mr. LiuZhiyuan (National University of Singapore)
The presentation started with a review of existing congestion

pricing schemes. Considering possible efficient implementationof the distance-based toll charge method with the aid of global
positioning system (GPS), an in-vehicle unit integrating a GPSreceiver, a digital map and a general packet radio service(GPRS) communication device, a Mathematical Programmingwith Equilibrium Constraints (MPEC) distance based toll designmodel was presented. The objective of the model was tomaximize the total societal benefit was formulated and wassolved using distributed genetic algorithm.
Presentation 5: “Path Risk in Hazardous Material Logistics” byRojee Pradhananga (Kyoto University)
A procedure to determine threshold distance λ for risk
analysis in routing and scheduling of hazardous material wasdiscussed during the presentation. In addition to the materialtype, the procedure takes into account the geographic andmeteorological condition of the area where the hazardous
material is being transported. A demonstration to the procedure
was presented considering logistics of Liquefied Petroleum Gas(LPG) in Osaka, Japan. The demonstration resulted a λ value of275 meters in all direction corresponding to worst case accident
scenario of Boiling Liquid Expanding Vapor Explosion (BLEVE).
Presentation 6: “An Ensemble Tree Approach for Work Zone
Capacity Estimation” by Dr Weng Jinxian (National University ofSingapore)
The presentation highlighted the importance of accurate
estimation of work zone capacity as being an essential
component in estimating work zone delays and planning workzone implementation. An ensemble tree approach wasproposed for accurate estimation of the work zone capacity. Theapproach uses a set of decision trees whose individual outputs
are combined using a weight method to reproduce the estimatesfor new examples.
Presentation 7: “Large-Scale Intermodal Liner Shipping
Network Design” by Mr. Wang Shuaian (National University ofSingapore)Starting with literature review of decision problems at tacticallevel of decision making in liner shipping, the presentation
introduced a practical large-scale intermodal liner shipping
network design. Intermodal transportation, multi-type containers,origin-to-destination transit time, account for the initial network,
global shipping network were the key features considered.
Presentation 8: “Analyses and Implications of the Accidents inthe Singapore Strait by Mr Qu Xiaobo (National University ofSingapore)
Underreporting of accidents being a subject of great concern
to maritime and port authorities, an underreporting analyses of
databases of accident in the Singapore strait was discussed
during the presentation.

Presentation 9: “Integrated Driving Behavior Model Considering
the Driver’s Latent Intention” by Mr. Masami Yanagihara (KyotoUniversity)
A driving behavior model considering driver’s intention duringtransition was presented. The model deals with driver’s speed
regulation and lane changing behaviors in an integratedframework. Numerical analysis was performed on vehicle
trajectory data from video image of Hanshin Expressway, Japan.

Conclusions
The workshop served as a platform to discuss several issues oftransportation and logistics with special concern to Asian
Mega-Cities. New ideas and new horizons to counteract humansecurity issues were addressed.
Finally the event was concluded with a members' discussion
on textbook publication and future collaboration.
