Introduction
UbiquitousNot new and surprising technology
But new paradigm found through existing and/or potential developing technologies
Features of the new paradigm (i.e., ubiquitous computing) From individual system into the integrated system
From operators and managers into end-users
From controlling and managing strategies into focusing on self-controlling and providing information
From unspecific users services into personal custom-made services

Introduction (cont.)
Today topicSo far now, most urban transportation systems are focused on separated
systems, featured by different services to operate and manage the city
Recently, they are changed into the integrated and standard systems by the development and variety of technologies
Thus, the current ITS need to be changed into the user-oriented, i.e., u-Service system.
5
Lifecycle of a New Technology Compared with acceptance of technologies, user’ acceptance of the
new one seem to be progressive Depending on the user’s activity, the acceptance of ubiquitous service
is expected to speed up Propagation Rates of Information and Communication Services

The final goal of city is to predict the citizens’ activities and to implement them properly
The metropolis is focused on resources, citizens, and their interactions to operate and manage the target city

ITS u-Transp.
• No identification in data collection (e.g., CCTV, Loop, etc)
• Aggregated analysis in data process
• Averaged provision of information and services
• Identification in data collection (e.g., RFID)
• Disaggregated and various analysis in data process
• Individual provision of information and services
ITS provide the basic subjects and technologies for u-City ITS provide unidentified users with the servicesu-Transportation provide identified users with the services

Changes and Roles of ITS for u-City [4]So far now, the current ITS has been focused on effective
management of the traffic flows,
but now, can consider the management of actual travel demand, using various IT
17
Need of Integrated Platform and Solution based Hi-technologies For the integrated services and individually user-oriented services in u-
Transportation,
The current systems and technologies need to satisfy the following
requirements
Open Center Platform
Mobile/Embedded/Wireless
CRM (Customer Relation Management)
Payment and Billing
Web Portal
Changes and Roles of ITS for u-City [5]
18
Issues of u-Transportation
Integration of information related contents for anytime, anywhere, any service
Roadmap for applying technologies and realizing the services
Re-construction of ITS architecturesbecause it did not consider new emerging solutions such as ubiquitous
Participation in other standardization projects in u-City for including the needs of ITS into ubiquitous standardization
Solutions for privacy problem for ITS services like as acquiring traffic information
19
Conclusions
Need to change the paradigm of the current ITS
u-Transportation in u-City
Need to build the roadmap for ITS development based on
understanding the ubiquitous technologies
Need to prepare for the open platform to support the integrated
ITS services
